Jakarta enforces odd-even traffic policy to counter jams

Posted on March 13, 2018 by Respro® UK Ltd

Officials aim to cut traffic coming into the city by 25 percent by the move.

Jakarta officials have introduced a rush-hour odd-even traffic control system on Jakarta-Cikampek Toll Road, the main toll road leading into the city, in order to cut traffic by 25 percent.

The policy was implemented on Monday and the first morning saw traffic moving at 60kmph and not the snail’s pace that motorists are used to.

More than 1.3 million people commute into Indonesia’s capital every day. In addition to cutting down the number of cars, officials aim to force commuters to use public transport by this move.

Only an estimated 20 percent of people in Jakarta use buses or trains.

A recent study done by Uber showed that Jakartans spend an average of 22 days a year stuck in traffic jams, more than any other city in Asia.

On odd dates, only plate numbers ending in odd numbers are allowed to enter the toll road between 6am and 9am. On even dates, it is the same for vehicles with plates ending in even numbers.

Drivers who violate the rule are forced to turn back and encouraged to take one of the busses the government has prepared at a nearby location.

“I’m now forced to take the bus and I don’t mind that,” Gaffy, a regular commuter, said.

“It’s a nice bus and this is a good method to convince people to use public transport.”

Others, however, feel the policy is discriminatory to people living in Bekasi, so far the only suburb of Jakarta where the policy applies.

As a spokesman for Indonesia Police Watch told local media, “the hellish traffic jams will only move elsewhere”.

Effective policy

It is a policy that has been used inside the city with mixed results, where the government said traffic has reduced by 15 percent.

But Tito Karnavia, the national police chief, admits the policy is not a solution to Jakarta’s notorious traffic problem.

“We have to do something than nothing. It’s not a silver bullet to erase the problem.”

While the construction of Jakarta’s first subway, an elevated toll road and a monorail is causing serious traffic jams, the government promises that these will reduce as soon as these projects are finished.

The jams not only eat up a lot of time, air pollution has been on the rise and business are losing an estimated $5bn annually.

Air pollution in the south 20 times above safe levels

Posted on March 12, 2018 by Respro® UK Ltd

Air pollution in the south of Malta has been more than 20 times above safe levels for the last week, according to European Environment Agency data. Experts who spoke to the Times of Malta, however, could not pinpoint an immediate cause for the apparently worsening conditions and warned that the data may be misleading.

Readings from the Żejtun air monitoring station – retrieved from the European Air Quality Index – show concentrations of fine particulate matter, known as PM2.5, averaging around 500 micrograms per cubic metre since at least March 4.

According to World Health Organisation guidelines, 25 micrograms is the limit for healthy exposure over a 24-hour period.

Fine particulate matter has a major impact on human health, according to the EEA, aggravating heart and lung disease and posing a serious threat to respiratory health for the general population.

The US Environmental Protection Agency defines anything above 250 micrograms as “hazardous” and recommends that everyone should avoid outdoor exertion, while those with respiratory or heart disease, as well as the elderly and children, should remain indoors.

The data should set alarm bells ringing
Martin Balzan, a respiratory health expert, told the Times of Malta PM2.5 readings at the Żejtun station were typically low due to the gas-fired power station and prevailing winds in the area.

He noted that the cause of the spike was unlikely to be traffic, as nitrogen dioxide levels had not increased, and cautioned that the readings could be an error or the result of an extremely localised event, such as a traffic detour or fireplace output close to the monitoring station’s sensors.

Engineer Arthur Ciantar, who has studied air quality in the area, said he could not recall such high levels of fine particulate matter before. Increases, he said, were most often caused by traffic, highlighting marine traffic and trans-boundary pollution as other contributing factors.

He added that, if accurate, the data should set alarm bells ringing and highlight the consequences of the region’s significant increase in traffic density.

A European Environment Agency report published last October found that Malta had the fourth worst levels of particulate matter in the EU – 50 micrograms per cubic metre, right at the European daily limit.

The report also found air pollution was responsible for 250 premature deaths in Malta in 2014.

A 2016 study by Dr Balzan and Michael Pace Bardon from the Department of Medicine at Mater Dei found pedestrians and cyclists in Fgura were exposed to three or four times more black carbon on the streets than indoors.

High air pollution levels prompt special weather statement for Calgary

Posted on March 9, 2018 by Respro® UK Ltd

Light winds paired with a change in temperature have trapped smog over Calgary, prompting a special weather statement alert from Environment Canada.

On Thursday at 5: 30 p.m., the agency warned that high levels of air pollution will remain over the city until westerly winds blow in later in the evening, dispersing the smog.

Environment Canada warned that people could experience symptoms including coughing, throat irritation, headaches and shortness of breath. Children, seniors and people with cardiovascular or lung problems are especially at risk.

The government’s Air Quality Health Index rated Calgary’s air as a high risk.

The risk is projected to drop to low by noon Friday.

Air pollution linked to brain alterations and cognitive impairment in children

Posted on March 9, 2018 by Respro® UK Ltd

A study examines the relationship between air pollution exposure during fetal life, brain abnormalities and cognitive impairment

A new study performed in the Netherlands has linked exposure to residential air pollution during fetal life with brain abnormalities that may contribute to impaired cognitive function in school-age children. The study, published in Biological Psychiatry, reports that the air pollution levels related to brain alterations were below those considered to be safe.

“We observed brain development effects in relationship to fine particles levels below the current EU limit,” said lead author Mònica Guxens, MD, of Barcelona Institute for Global Health (ISGlobal), Spain, a center supported by the “la Caixa” Foundation, and Erasmus University Medical Center, the Netherlands. This finding adds to previous studies that have linked acceptable air pollution levels with other complications including cognitive decline and fetal growth development. “Therefore, we cannot warrant the safety of the current levels of air pollution in our cities,” said Dr. Guxens.

Exposure to fine particles during fetal life was associated with a thinner outer layer of the brain, called the cortex, in several regions. The study showed that these brain abnormalities contribute in part to difficulty with inhibitory control — the ability to regulate self-control over temptations and impulsive behavior — which is related to mental health problems such as addictive behavior and attention-deficit/hyperactivity disorder.

The study used a population-based cohort in the Netherlands, which enrolled pregnant women and followed the children from fetal life onward. Dr. Guxens and colleagues assessed air pollution levels at home during the fetal life of 783 children. The data were collected by air pollution monitoring campaigns, and included levels of nitrogen dioxide (a prominent air pollutant caused by traffic and cigarette smoking), coarse particles, and fine particles.

Brain imaging performed when the children were between 6 and 10 years old revealed abnormalities in the thickness of the brain cortex of the precuneus and rostral middle frontal region. Despite the relationship between these brain structure alterations and fine particle exposure, the average residential levels of fine particles in the study were well below the current acceptable limit set by the EU — only 0.5 percent of the pregnant women in the study were exposed to levels considered unsafe. The average residential levels of nitrogen dioxide were right at the safe limit.

“Air pollution is so obviously bad for lungs, heart, and other organs that most of us have never considered its effects on the developing brain. But perhaps we should have learned from studies of maternal smoking that inhaling toxins may have lasting effects on cognitive development,” said John Krystal, MD, Editor of Biological Psychiatry.

The fetal brain is particularly vulnerable during pregnancy — it hasn’t yet developed the mechanisms to protect against or remove environmental toxins. The findings of the study suggest that exposure to levels even below those considered safe could cause permanent brain damage.

“Although specific individual clinical implications of these findings cannot be quantified, based on other studies, the observed cognitive delays at early ages could have significant long-term consequences such as increased risk of mental health disorders and low academic achievement, in particular due to the ubiquity of the exposure,” said Dr. Guxens.

Medellin issues red alert over ‘harmful’ air

Posted on March 8, 2018 by Respro® UK Ltd

Medellin partially banned motorized traffic and reduced economic activity on Wednesday “to protect citizens” from pollution that has made air “harmful” for people’s health.

The red alert that was issued bans more than half of the city’s cars and physical activity for children in schools. Businesses that have failed to adhere to environmental regulations were ordered to immediately stop operations.

The state of alert is the second in two years and occurred only weeks after the city government announced it had closed a pact with the private sector to reduce air pollution.

The restrictions on traffic, industry and school activities will remain in place at least until Friday, local authorities said. The measures can be extended if the air quality has not improved by then.

Why this is happening
The exhausts of cars and factories have reduced air quality to the point it is considered harmful, especially for elderly citizens and children.

A rapid increase in car ownership in the fast-developing city of 2.5 million has led to excessive pollution.

According to transit authorities, one in every three cars in Medellin does not comply with environmental regulations.

Gasoline and diesel provided by state-run oil company Ecopetrol contain excessive levels of harmful chemicals, like sulfur, that would make the fuel illegal in developed economies like the United States and the European Union.

The city’s geographical location — Medellin lies in a valley — does not allow the exhausts of cars and factories to blow away. This is particularly an issue in March, a month in which there is hardly any wind or rain because of the dry season.

Is this the new normal?

Medellin mayor Federico Gutierrez announced in February that the city’s administration and private sector had agreed to measures that would curb the deterioration of air quality.

Environmental activists, however, have said the pact was “superficial” and fails to tackle the primary causes of pollution, low-quality fuel and an outdated fleet of privately-owned buses.

Ecopetrol has refused to sign this pact, arguing that its fuel quality is higher than demanded by government regulators.

Local transport companies have also refused to take part as they would have to cover the cost of filtering Ecopetrol’s notoriously bad fuel.

If the national government were to impose norms similar to those in the US, sulfur levels could drop to 5% of what they are now. Congress, however, is busy with elections. The national government has less than six months left in office.

Dangerous pollution spreads to Northeastern region

Posted on March 6, 2018 by Respro® UK Ltd

Air pollution from a high level of particulate matter smaller than 2.5 microns (PM2.5) has continued to intensify. The problem is no longer limited to the Northern region, but also to the Northeast.

Tak’s Mae Sot district was found to have the most severe air pollution problem from PM2.5 in Thailand. The PM2.5 peak level as of Tuesday morning, measured by the Pollution Control Department (PCD), was as high as 211.21 milligrams per cubic metre of air, while the PM2.5 daily average level was at 133.41 milligrams.

Lampang was the second most hazardous area, as the PM2.5 level reached as high as 189 milligrams in the morning and the daily average was 133.5 milligrams.

The PM2.5 level at Khon Kaen in the Northeast rose up to 132.17 milligrams on Tuesday morning and had a daily average at 90.2 milligrams.
Chiang Mai and Nan also suffered from harmful levels of PM2.5, as PCD’s data revealed daily averages of 96.34 and 49.1 milligrams respectively.

Thailand’s safe standard for daily-average PM2.5 is 50 milligrams, while the World Health Organisation’s recommended level is just 25 milligrams.

According to medical experts, long-term exposure to PM2.5 can cause many fatal diseases such as lung cancer, stroke and heart disease, and lead to premature death.

Old Cars Bringing More Air Pollution to Croatia

Posted on March 5, 2018 by Respro® UK Ltd

When it comes to the impact of transport on air quality in Europe, cars in the Czech Republic, Poland and Estonia fare the worst and they are labelled by the Eco Experts organisation as the most toxic drivers, while Croatia ranks the fifth on the list of 25 European countries.

The ranking was compiled according to the results from several criteria: the average vehicle age, the number of vehicles per 1,000 inhabitants, the percentage of alternative fuel passenger cars, and air pollution.

Motorists in the Czech Republic were named the most toxic in Europe, according to the report released by the British organisation Eco Experts. Not only do Czech motorists have the 6th lowest number of alternative fuel vehicles (0.7%), their cars are also the 6th oldest on average at 14.5 years old, according to the findings of the report.

“Vehicle owners in Poland came in at a close second. Despite having the highest number of alternative fuel passenger cars (15.5%) in the research, the eastern European country performed poorly on all other measures of vehicle toxicity. Most notably, Poland is home to the oldest cars in Europe (17.2 years on average) and has the highest recorded ambient air pollution in the continent,” reads the research.

“Estonia was found to be home to the third most toxic drivers in Europe, owing to its citizens driving the 5th oldest vehicles on average at 15.1 years old, and having the fifth highest number of vehicles per capita. The country also has a very low percentage of alternative fuel vehicles, at a mere 0.6%.

“Croatia and Slovakia completed the list of the top 5 most toxic drivers in Europe, with motorists in countries such as Slovenia and Romania not far behind.”

In terms of the number of vehicles per 1,000 inhabitants, Croatia ranks 25th (with 392 cars per 1,000 inhabitants). Only Latvia, Hungary and Romania have fewer cars per 1,000 inhabitants. Measured by this criterion, Malta and Luxembourg top the list.

In Croatia, the average vehicle age is 14.1 years.

Public at risk from ‘daily cocktail of pollution’

Posted on March 2, 2018 by Respro® UK Ltd

 

People are being exposed to a daily cocktail of pollution that may be having a significant impact on their health, England’s chief medical officer says.

Prof Dame Sally Davies said the impact of air, light and noise pollution was well recognised in the environment.

But she said its role in terms of health was yet to be fully understood.

Dame Sally added there was enough evidence to suggest action had to be taken.

And, in her annual report, she said the NHS could lead the way in cutting pollution levels.

She said one in 20 vehicle journeys was linked to the NHS, either from patients or staff travelling.
And making sure services were brought out of hospitals and closer to people’s homes could help reduce that burden.

Dame Sally also pointed to the attempts being made to phase out ambulances run on diesel, a key source of nitrogen dioxide, which is linked to respiratory disease.

And she said the NHS could cut its use of disposable plastics, landfill and incineration.
While air pollution does not kill people directly, it can shorten their lives by undermining the health of people with lung problems and heart disease.

Previous research has suggested it may be a factor in one in 12 deaths and is the ninth leading factor for mortality in the UK – tobacco, diet and high blood pressure are the top three.

But Dame Sally said there was also a question about how air, light and noise could coincide to have an impact on long-term health.

“With factors like air, light and noise, the public is exposed to a daily cocktail of pollutants,” she said.

“Some of these can be linked to chronic conditions like heart disease and asthma.

“This increases the risk for some of the most vulnerable members of our society and places a huge burden on our health service.”
