France to require ‘clean stickers’ on vehicles in high pollution areas

Vehicles failing to display Crit’Air stickers will be banned from low-emission zones in Paris and other cities in bid to combat smog

French motorists in high pollution areas will be required to display a “clean sticker” on their vehicle from January to combat pollution that has created a cloud of noxious smog in Paris and other cities.

The six differently coloured Crit’Air (air criteria) stickers will be large enough for the police to see at a distance and will indicate the age of the vehicle, its engine and cleanliness on a scale of one to six.

Although emergency vehicles, vintage cars and certain delivery and security vans will be exempt from the regulation, to take effect from 16 January, stickers will be obligatory for motorbikes and scooters.

On weekdays, vehicles without the stickers will be banned from entering designated zones à circulation restreinte (ZCR – low-emission zones), which will be determined by local authorities based on pollution evaluations.

Announcing a raft of measures to combat the increasing problem of pollution in France’s cities, the ecology minister, Ségolène Royal, said the government was “taking the problem seriously”.

“What we now need is a revolution bringing clean transport, responsible cities, electric vehicles in cities and different ways of moving around,” Royal said.

The alternating traffic rule – in which cars with odd or even registration plates are banned from cities – was enforced for a record four days in Paris last week. It was dropped after the pollution improved over the weekend when the roads were less busy. But Airparif, which monitors air quality in the French capital, warned that the smog, which led to a rise in asthma and hospital admissions for breathing difficulties and caused schools to cancel outdoor sports, could return with the rush-hour traffic on Monday.

Other measures announced include an extension of the “superbonus scheme” in which vehicle owners can obtain a €10,000 (£8,400) payment for changing an old polluting vehicle for an electric one. Until now this has been offered to private car owners but is to be extended to taxis and vans.

From January, the government will also offer €1,000 to those buying an electric scooter.

The Paris mayor, Anne Hidalgo, who has made fighting pollution in the city a priority, has declared she wants the capital free of diesel vehicles by 2020 and the whole of France by 2025.

Air pollution impairs function of blood vessels in lungs: Authors recommend limiting physical activity in heavily polluted areas 

Air pollution impairs the function of blood vessels in the lungs, according to a study in more than 16,000 patients presented today at EuroEcho-Imaging 2016.

“This is the first human study to report an influence of air pollution on pulmonary vascular function,” said lead author Dr Jean-Francois Argacha, a cardiologist at the University Hospital (UZ) Brussels, Belgium. “This is a major public health issue for people living in polluted urban areas where exercise could damage the lungs and potentially lead to decompensated heart failure.”

Promoting a safer environment appears to be as important as controlling conventional risk factors, like high cholesterol, in reducing cardiovascular disease. Air pollution consists of particles (particulate matter [PM] of different sizes) and gases (nitrogen dioxide, ozone, etc). The first vascular bed in contact with air pollutants is the pulmonary circulation yet few studies have investigated the impact.

“Such studies are important because if air pollution causes narrowing of the blood vessels in the lungs (vasoconstriction), this combined with the systemic effects of pollution could cause decompensated heart failure,” said Dr Argacha.

The current study examined the effect of air pollution on pulmonary haemodynamics in a population and in individuals. The population study assessed whether common levels of outdoor air pollution influence the echocardiography parameters conventionally used to evaluate the pulmonary circulation and right ventricular function. Between 2009 and 2013, transthoracic echocardiography including an evaluation of pulmonary pressure was conducted in 16 295 individuals and correlated with average air pollution in Brussels on the same day and in the last five and ten days. The authors examined whether any patient subgroups were more susceptible to the effects of air pollution.

The individual study examined the effect of air pollution on pulmonary circulation in ten healthy male volunteers exposed to pollutants in a chamber with standardised conditions. The volunteers were exposed to ambient air or dilute diesel exhaust with a PM2.5 concentration of 300 ?g/m3 for two hours in a randomised, crossover study design. The effects on pulmonary vascular resistance were assessed with echocardiography at rest and during a cardiac stress test in which the drug dobutamine is given to simulate heart function during exercise.

The population study showed a negative effect of PM10, PM2.5 and ozone on pulmonary circulation on the same day and over five and ten days. Specifically, increases in these pollutants were associated with reduced pulmonary acceleration time and increased pulmonary acceleration slope. Increases in PM10 and PM2.5 over ten days were associated with worse right ventricle function. The negative impact of PM10 on pulmonary circulation was more pronounced in patients with obstructive sleep apnoea.

Dr Argacha said: “Air pollution was associated with increased pulmonary vascular tone which makes it more difficult for blood to flow to the lungs. Longer exposure to air pollution exposure seems necessary to impair right ventricular systolic function. Patients with obstructive sleep apnoea were at greater risk.”

The individual study showed that exposure to diesel exhaust did not modify the pulmonary circulation compared to ambient air when the volunteers were resting but did when dobutamine was administered. “This suggests that pollution is more harmful to the lung circulation during exercise,” said Dr Argacha.

He continued: “Our dual approach provides original data on the impact of air pollution on the pulmonary circulation. The individual study strengthens the plausible link emerging from the epidemiological research.”

Regarding how to minimise the health risks, Dr Argacha said: “Our main advice is to limit physical activities during heavy air pollution. More studies are needed before specific recommendations on intensity and duration of exercise can be given. Emission controls such as particulate filters have reduced tailpipe emissions, but other sources such as engine crankcases, tyres and brake wear are becoming important. No strong evidence exists on effectiveness of face masks to eliminate or reduce particle exposure.”

He added that legislation protecting the population from air pollution is weak. He said: “Diesel emission control has been associated with health outcomes5 but unfortunately the standards defined by the European Union differ from those of the World Health Organization.

Running home from work in high air pollution could be deadly, study suggests 

Running or cycling home from work when air pollution is high could damage the lungs and lead to heart failure, a new study suggests.

Researchers in Belgium have discovered that the pollution causes blood vessels in the lungs to narrow, which prevents oxygen circulating effectively through the body, and could lead to cardiovascular disease.

“This is a major public health issue for people living in polluted urban areas where exercise could damage the lungs and potentially lead to decompensated heart failure,”  said lead author Dr Jean-Francois Argacha, a cardiologist at the University Hospital  Brussels.

“Our main advice is to limit physical activities during heavy air pollution. No strong evidence exists on effectiveness of face masks to eliminate or reduce particle exposure.”

Researchers looked at more than 16,000 people who had been admitted to hospital in Belgium between 2009 and 2013 and who had an echocardiogram taken to show the movement of blood through the heart.

They then compared the results to air pollution records and found that on average patients had worse circulation on days where pollution was high, or had been in the week before admission.

In a second experiment scientists exposed 10 healthy male volunteers to pollution in a chamber and tested their lung function at rest, and when taking a drug which simulates heart function during exercise.

Although there was no impact when resting, circulation worsened when the drug was administered.

“This suggests that pollution is more harmful to the lung circulation during exercise,” added Dr Argacha.

“Our dual approach provides original data on the impact of air pollution on the pulmonary circulation.”

The research was presented at the EuroEcho-Imaging annual meeting in Leipzig, Germany.

Parisians grapple with worst winter pollution in a decade

Under deceptively blue skies, the marvels of Paris beckoned. But art dealer Sophie Vigourous wore a face mask to appreciate them because of the pollution.

Under deceptively blue skies, the marvels of Paris beckoned. But art dealer Sophie Vigourous wore a face mask to appreciate them because of the pollution.

The 38-year-old has lung cancer, putting her in the groups most at risk from the toxic, throat-tickling broth of tiny particles — far smaller than the width of a human hair — blanketing France’s capital and other cities. It has prompted vehicle bans and other extraordinary but only moderately effective anti-pollution measures.

When viewed from the 210-meter (690-feet) tall Montparnasse Tower, Paris’ tallest skyscraper, the city’s worst episode of winter pollution in a decade was clearly visible, a brown haze punctured by the Eiffel Tower.

But from street level, the fog of lung-penetrating pollutants was less obvious, making the danger more insidious than the gritty, almost chewy, smog of notoriously unhealthy cities like Beijing.

Out on their morning jog, a group of heavy-breathing fire officers in shorts and T-shirts sucked in lungfuls, either oblivious or uncaring. Likewise, the jogger who bounded up the Champs-Elysees, a smug smile on her face.

Vigourous, however, knew better: hence the paper face mask.

“A nice day like this makes you want to go out for a walk and get some fresh air,” she said. “You can’t really feel it, the pollution.”

But by the end of the day, “it stings,” she noted.

Large red stains showing the pollution cloud have covered daily maps produced by Airparif since last week, broken up by a two-day window of cleaner air last weekend. The monitoring agency says a high-pressure weather system and a low-altitude blanket of warmer air over the city are acting like a saucepan lid, forcing Paris to breathe its own trapped emissions.

“An anti-cyclone with very little wind that prevents the dispersion of pollutants,” Airparif spokeswoman Amelie Fritz explained.

The problematic pollutant this time is particulate matter — “very fine dust,” mostly from vehicle emissions and wood-burning heating, Fritz said. Able to penetrate the lungs and bloodstream, the tiny PM10 particles can cause heart disease, lung cancer, asthma and acute respiratory infections, according to the World Health Organization.

The response from Paris authorities involves both carrot and stick. To encourage car users to switch to public transport, the Metro, suburban trains and buses have been free since Tuesday, at a cost, Paris region authorities say, of about 4 million euros ($4.3 million) per day. Paris’ Velib bicycle-sharing service and Autolib electric cars are offering special deals.

On the punitive side, the Paris police chief has reduced speed limits, banned outdoor and indoor fires and even required homeowners to restrict their heating to no more than 18 C (64 F).

The headline measure, an alternating ban on cars, depending on whether they have odd or even-numbered plates, has been extended into Friday. Drivers face fines of between 22 ($23) and 75 euros ($80) for ignoring the rule. A similar scheme will be implemented Friday in the city of Lyon, as pollution hits various regions, including the Rhone valley.

But the Paris ban doesn’t apply to small trucks, trucks delivering food and other essentials, to cars carrying at least three people and to certain professions. Undertakers and journalists, for example, aren’t affected. The boulevards still hum with vehicles.

“We’ve noticed that the measures haven’t been followed that much,” said Fritz at Airparif. “We’ve noticed only 5 to 10 percent less traffic.”

Among those who abided by the rule on Thursday were Marion Le Mouroux, her mother and sister. Leaving their diesel-burning Renault at home, they rode together to work in an Autolib. The electric cars weren’t affected by the ban.

“It’s worrying for our future,” Marion Le Mouroux said after connecting the vehicle for a recharge. “If we are generating this much pollution, what’s going to become of us.”

Why Madrid Is Going Car-Free This Holiday Season 

The city center will be nearly car-free for nine days.

Madrid just gave its citizens a present for the holidays. The city closed the entire city center to most cars, turning the urban core into a de facto pedestrian zone.

Starting last Friday at 5 p.m. and continuing for nine days, vehicles belonging to non-residents are banned from entering a zone covering Madrid’s historic core as well as Gran Via, the blaring, multi-lane avenue that serves as the Spanish capital’s main drag and as a major through-route for crosstown traffic.

Buses, cabs and residents’ cars will still be crawling the streets, although restricted to a specially lowered 30 kmh (18 mph) speed limit. The otherwise blanket ban in the throbbing, vehicle-packed heart of a major metropolis is one of the boldest anti-car plans seen in Europe so far. To get a loose idea of the scale in American terms, imagine banning all cars in Manhattan from driving south of 14th Street.

The restrictions, which end Sunday at 10 p.m., couldn’t come at a better time. It’s not just that the holiday shopping season is in full swing in Spain’s busiest commercial district, making the place a whole lot more manageable for shoppers on foot. Spain also has two national holidays this week: Tuesday’s Constitution Day and Thursday’s Immaculate Conception Day. These make early December a classic choice for Spaniards who want to take a week off without squandering too much of their paid vacation allowance. As you’d expect, crowds in the streets are thicker than usual, while the area’s arterial roads tend to get more than a little snarled up. The temporary ban is likely to make the whole area… well, just nicer.

Winter is also a period when Madrid’s air quality needs all the help it can get. Thanks to a seasonal inversion effect, Madrid’s plateau location helps trap fumes into a noxious greige-colored cap known locally as La Boina (“the beret”). Discouraging cars from central Madrid won’t just make the streets a lot more attractive to pedestrians. By keeping keys out of car ignitions, it could also ensure that city residents get to breathe a little more freely for a week.

That should make this week far more pleasant for Madrid residents, who will benefit from increased metro services to get them into town during the shutdown. But like a puppy given as a gift, the plan will have a long life beyond Christmas. The car-free week is a harbinger of further reductions to come. Madrid is planning to cut the number of car lanes along Gran Via, expanding sidewalks to take their place so that the roaring car canyon becomes a pleasant place to stroll. This makeover is due to arrive in summer 2017.

Meanwhile, new car parks are due to be constructed around the edge of the current semi-car-free zone, so it becomes easier for drivers to ditch their vehicles and switch to public transit as they descend on the dense, frequently knotty streets at Madrid’s heart.

The city plans to have a fleet of 2,000 clean electric buses on its roads by 2020 to absorb some of the escapees from private cars. And finally, there are further plans in the works to divert traffic away from central Madrid entirely, though these early-stage proposals still have a few more hoops to jump through before they’re made public. All this comes on the back of past temporary driving bans during winter pollution peaks, designed to soften the worst excesses of air pollution when La Boina is hanging especially heavily over the city. Slowly but surely, the city is getting people used to the idea of not driving into downtown, while also letting them see how much more pleasant and healthy the area is without cars when they actually get there.

By taking the softly, softly approach to cutting car use, Madrid may well be emulating Paris. The French capital’s total ban on cars on the Seine’s right bank was wisely preceded by closing the area in question to host a temporary summer beach. As locals got used to this seasonal closure, extending it into the autumn and thereafter became a far-narrower psychological chasm to jump across, even if reaction from authorities in the greater Paris region has been pretty combative. Madrid has a similar split to Paris’, between a left-leaning city government and a right-leaning one in the region immediately surrounding the city limits, so a similar stand-off between city and exurbs is not unthinkable.

Madrid has already successfully banished most cars from its center in the past—it began doing so for two days of its Mobility Week in September 2015. Moves like this aren’t entirely contested, of course. But by slowly introducing a less car-dependent city—as a seasonal treat rather than a gray bureaucratic edict—Madrid isn’t just pushing toward a cleaner future. It’s steadily building the consensus necessary to make sure that future is what most people in the city actually want.

Get your masks out! Delhi’s air quality ‘severe’, to get worse this week 

Air quality in the Capital worsened on Wednesday as pollution levels in various parts of the city reached “severe” proportions.

Air quality in the Capital worsened on Wednesday as pollution levels in various parts of the city reached “severe” proportions.

Although the overall Air Quality Index read 379, which is “very poor”, Pusa Road had the AQI at 404, Dhirpur 441, Delhi University 458, IGI Airport 438 and Pitampura 431. These are all in the severe category. The monitoring station at Lodhi Road recorded a maximum AQI of 500.

Air pollution level is classified as severe if the AQI is between 401 and 500. China declares a “red alert” at this level.

Severe AQI for three consecutive days is met with desperate measures such as shutting down of schools and offices, closing down industries and power plants and rationing of vehicles on the roads.

SAFAR has advised people to avoid all outdoor physical activity. People with heart or lung diseases, senior citizens, and children should remain indoors and keep activity levels low when air quality turns “severe”, it said.

People with existing heart or lung diseases such as asthma, congestive heart disease, or ischemic heart disease should avoid heavy exertion when the air quality is “very poor”.

In the morning, the 24-hour rolling average of PM10 and PM2.5 touched poor and very poor limits, respectively, according to System of Air Quality Weather Forecasting and Research (SAFAR) data, reading 346 and 174 microgram per cubic metre respectively. These, too, became fouler as the day progressed clocking 408 and 222 microgram per cubic metre.

PM2.5 and PM10 are ultrafine particles that are the dominant pollutants in Delhi. The 24-hour acceptable levels of PM 2.5 and PM10 are 60 and 100 microgram per cubic metre, respectively.

According to forecasts, the air-quality may get fouler over the next couple of days.

“Cold winds from the Indo-Gangetic plains are bringing in pollution to the Delhi region and as a result air is getting fouler. The air quality will keep getting worse till Thursday when PM2.5 is expected to touch 200g/m³,” Gufran Beig, programme director of SAFAR, which comes under the earth sciences ministry, told HT.

With patterns and directions changing, dense fog has returned to Delhi. Officials predict dense to very dense fog on Thursday morning.

The change in weather, in terms of dense fog, comes with the return of easterly winds. “There is also a cyclonic movement of air over the Bay of Bengal. The factors raise moisture in the air, which in cold climates can lead to fog,” a scientist said.

The minimum temperature on Wednesday was recorded at 11.2°C, which is two notches above average for this time of the year, a MeT official said. The maximum was recorded at 24.3°C, which is normal. On Thursday, the maximum and minimum temperature will be around 25°C and 12°C, respectively.

Paris bans cars for second day running as pollution chokes city 

Vehicles with odd-number plates were banned on Tuesday and, on Wednesday, it was the even numbers’ turn

Paris authorities restricted traffic in the city for a second day after a “lid of pollution” sealed the capital, causing concern over public health.

Photographs showed a grey veil of dirty air trapped over the city, masking the horizon and, at times, landmarks such as the Eiffel Tower. Experts said it was the longest most intense spike in pollution for at least 10 years and was expected to continue for at least another day if not longer.

Following a ban on vehicles with odd-number licence plates on Tuesday, it was the turn of those with even numbers to be told to leave the car at home on Wednesday. To encourage them, public transport in the city and suburbs was free.

The alternate-day vehicle bans have only been introduced four times in the last two decades, and never before for two consecutive days.

“Without it the air would be even more polluted. It’s an emergency solution to an urgent problem,” Charlotte Songeur of Airparif, which measures air quality in the French capital, said.

She added: “Even before this, 1.6 million French people were breathing in a level of nitrogen dioxide over European recommended levels.”

High levels of pollutant gases and fine lead particles can cause asthma, allergies, breathing difficulties and heart diseases.

The Paris prefect, Michel Cadot, said the ban would be extended to a third day if air quality did not improve.

The spike in pollution was blamed on anticyclonic weather conditions, little wind combined with the cold snap keeping the pollution from escaping, and people turning up their gas heating or lighting fires.

“As long as the meteorological situation remains the same and emissions remain the same, we will not see the end of the pollution spike,” said Cadot.

The level of PM10 lead particles in Paris was higher than the recommended 80 micrograms per cubic metre several days last week.

However, because the alternating traffic rule is only introduced after four consecutive days of continuous high pollution – and the traffic level dropped at the weekend – it was not introduced on Monday, causing criticism of the authorities when the levels shot back up again. Air quality controllers also noted a jump in nitrogen dioxide levels from last Thursday.

The air quality was said to be bad in other French cities, including Grenoble and Lyon.

Sébastien Vray, president of the group Respire (Breathe), said there were 48,000 premature deaths in France each year due to air pollution. “It’s the third biggest cause of death, but politicians only react under the pressure of public opinion,” Vray told France TV Info.

“It’s now 40 years that we’ve had health problems linked to air pollution. Organisations measuring air quality give the same reports each year … what are we waiting for to bring in technological change? Our carmakers have known for the last 40 years they can improve their engines with increasingly efficient technology and the state must better inform the public to help them change.”

Motorists who ignored the ban aimed at cutting traffic were fined €22 (£19).

The mayor of Paris, Anne Hidalgo, who has made tackling pollution a priority, tweeted a photograph taken from an aircraft over the capital showing the city covered in a grey blanket, with only the top of the Eiffel Tower visible. “Proof of the necessity to reduce the place of the car in city centres,” she wrote.

Londoners urged to leave cars at home as polluted air drifts in from Europe 

Motorists in London were to leave their cars at home on Monday as air pollution drifted in from Europe. Westminster and the City were among the worst-affected areas, along with other busy roads, while the rest of London was issued with “moderate” warnings.  Experts at King’s College’s pollution monitoring centre, London Air, said levels of toxic fumes were thought to be particularly bad in the capital as polluted air flows across the channel from France.

Experts at King’s College’s pollution monitoring centre, London Air, said levels of toxic fumes were thought to be particularly bad in the capital as polluted air flows across the channel from France.

Green Party Assembly Member Caroline Russell said car-free days were no replacement for decisive action on the capital’s traffic problem.

“It’s great the Mayor has issued air pollution warnings but these don’t go far enough, you need to tackle pollution at its source not just tell people that it’s happening,” she told The Independent. 

“I have supported the Mayor’s idea for Paris-style ‘car free’ days but car free days are no substitute for decisive action on air pollution and traffic reduction.”

Green Party peer Jenny Jones suggested Mayor of London Sadiq Khan should urge motorists not to drive during the air pollution spike.

Public Health England advice for moderate air pollution cautions adults and children with lung or heart problems, who experience symptoms, to consider reducing strenuous physical activity, particularly outdoors.

Pollution is considered by the size of its particulate matter, with PM2.5 thought to be particularly dangerous for its ability to enter the lungs and seep into the bloodstream.

Diesel emissions are also known to produce high amounts of nitrogen dioxide pollution, thought to be significantly more harmful than emissions from petrol vehicles.

Mr Khan recently announced plans to spend £770 million on cycling schemes over the next five years to make cycling a “safe and obvious choice for Londoners”.

Ms Russell, who launched the plan Prioritising People in November to encourage the mayor to do more to deliver healthy streets, said extra investment was the only way to reduce pollution in the capital.

“Obviously the best way to bring pollution down is to make driving a bit less convenient and walking, cycling and public transport much more convenient, pleasant and affordable,” she told The Independent.

“Those vulnerable to dirty air risk their health just stepping outside their front doors. How much more are Londoners expected to take?”

According to City Hall, nearly 10,000 people die each year as a result of London’s poor air quality.

The Mayor has already pledged to pedestrianise Oxford Street and introduce low emissions zones in the capital to tackle the problem.

Last week, he introduced “anti-idling” pollution alerts at 2,500 bus stops and river piers, the entrances of all 270 Tube stations and on 140 signs next to the busiest main roads into London, with instructions to switch engines off when stationary to reduce emissions.

A spokesperson for Mayor of London Sadiq Khan said: “The Mayor is delivering hard-hitting measures to rid London of the dirtiest diesel long before 2025.

“His immediate plans include charges for the most polluting diesel cars in central from 2017 and bringing forward and extending the Ultra-Low Emission Zone which removes all but the newest Euro 6 diesel vehicles from as early as 2019.

“Across London all heavy vehicles will have to meet the same Euro 6 standard which removes the oldest models.

“The Mayor is transforming London’s buses into one of the greenest fleets in the world and last week announced no more pure diesel buses will be procured from 2018. The Mayor is doing everything in his power to tackle London’s toxic air and get rid of the most polluting vehicles, but he cannot do this alone and is calling on the Government to face its responsibility and implement a national diesel scrappage scheme now.”
