Tower Bridge: drivers urged to turn off engines while boats pass

The Tower Bridge anti-idling campaign – a joint initiative by Southwark and Tower Hamlets councils – is one of a number of projects to be backed by the Mayor of London’s Air Quality Fund.

“This is all about helping local people to take forward projects that they know will help tackle the most polluted parts of their neighbourhoods,” said Boris Johnson, Mayor of London, who has awarded £100,000 to the Tower Bridge project.

“The more we work together to tackle air quality, the bigger the potential impact, and this funding will be used to make a real improvement.”

The two councils will install variable message signs on roads leading to the bridge which will tell drivers how long they are likely to wait when the bridge is raised.

The signs will urge drivers to switch off their engines while they wait for the bascules to be lowered and the bridge to be reopened to road traffic.

North Circular air pollution worst in London, emissions figures show

The North Circular, which carries more than 60,000 vehicles a day, has the worst traffic fumes of any road in London, according to official emissions figures released under freedom of information legislation.

Exhaust emissions data held by Transport for London show that a stretch of the road near Walthamstow ranked highest for four of the five most dangerous air pollutants, including benzene, nitrogen oxides (NOx) and fine particles of unburned carbon called PM10s and PM2.5s.

Four of the capital’s five worst roads for air pollution pass through some of the poorest areas of east London, including the A13 in Tower Hamlets and the Dartford crossing (A282) near Thurrock.

Oxford Street and Piccadilly in central London ranked in the worst 15 roads, due to the large number of buses and taxis. In west London and the wealthy stockbroker belt the air is cleaner, with roads in Weybridge, East Molesey and Esher the cleanest of the 41,713 recorded last year.

Air pollution from traffic is linked to strokes, heart and respiratory diseases as well as some cancers and asthma. About 4,300 premature deaths a year are attributable to air pollution, according to studies for the London mayor, Boris Johnson.

Pollution watchdog groups accused the government of trying to conceal the seriousness of traffic pollution. According to the data, which does not include pollution from brakes and tyres, Marylebone Road in the city centre ranked 1,074th for NOx levels and 1,126th for particulate pollution, yet was consistently said by government to be the worst in the capital.

Jenny Jones, a Green party London Assembly member, said: “[The government] has been fooling the EC by understating how bad pollution is on many roads. Oxford Street and some local shopping areas appear to be more polluted than Marylebone Road, but the government seems reluctant to measure air pollution where it could be having the biggest impact on people’s health.”

The mayor’s office said: “Strenuous efforts are being made to improve air quality in the capital. The mayor has tightened regulations on vehicles in the low emission zone, one of many changes that have resulted in emissions of dangerous particulates (PM10) falling by 15% and of oxides of nitrogen by 20%.”

The data raises new questions for Johnson’s plans for two new east London river crossings, because the figures show that any new bridges or tunnels built would increase the health risks in areas already among the most polluted in the capital.

London has the highest levels of nitrogen dioxide (NO2) of any capital city in Europe. Fifteen other British cities and regions – including Manchester, Birmingham and Glasgow – are heavily polluted by traffic and, according to the government, are not going to meet the legal requirements for lowering emissions for at least seven years.

Last month the supreme court ruled that Britain was in breach of EU law on NO2 emissions from exhausts. The case will now be heard in the European court of justice, and the government could face stiff fines.

Parliament’s environmental audit committee estimates that outdoor air pollution causes 29,000 deaths a year in the UK, compared with fewer than 2,000 a year caused by road traffic accidents.

Simon Birkett, director of Clean Air in London, which applied for the data, called on the government to ban diesel vehicles in the worst affected areas. “Hundreds of thousands of people are being gassed and showered in deadly particles from taxis and diesel vehicles,” he said. “All diesel vehicles from the most polluted parts of London should be banned by 2020.”

PM stands for Particular Matter

PINK SPORTSTAIt is the term for particles found in the air including dust, dirt, soot, smoke and pollen.  Particles can be suspended in the air for long periods of time. Some are large or dark enough to be seen such as soot or smoke and some are invisible to the naked eye.

As in the case of air quality in Beijing earlier this year and the current levels being experienced in Singapore, it is a concern to peoples health when PM level counts are high with a readings in excess of 300 on the pollution index and is measured in micrograms per cubic metre of air.

Particulate Matter comes in a wide range of sizes, measured in micrometres or ‘microns’. Like inches, metres and miles, a micron is a unit of measurement for distance, a very small distance. There are 1000 microns in one millimetre and the width of a hair on your head is between 100 and 500 microns. A typical range of particles found in city air would be in the order of 50+ microns in size down to less than 1 micron in size.

Particles that are 50+ microns in diameter can be seen by the naked eye, but as they get smaller they tend to invisibility. (The Invisible Threat)

Particles less than 10 microns in diameter (PM10) start to pose a health concerns because they can be inhaled into the back of the throat region causing irritation and coughing.

Particles less than 2.5 microns in diameter (PM2.5) which include sub micron particulates (less than one micron) are referred to as fine or ‘respirable’  particles and are believed to pose the greatest health risk.
Because of their size,  the normal human filtering system the nose and its nasal hair are unable to trap these fine particulates. They pass through the upper airways and deep into the the fine capillaries and air sacs which is where the oxygen exchange occurs to oxygenate the blood.
Current concerns are that very small amounts of toxic or carcinogenic chemicals like the VOC pyrene and Benzene are carried on the particle and taken to the point of exchange, which allows for the potential of the chemical agent to be absorbed into the blood stream and affect other vital organs.

A typical sample of black smoke emitted from one of the more popular people carrying vehicles,  would include particles from 100 microns to particles less than one micron in size. The sizing variation comes from the type of fuel being burnt and how efficiently it is being burnt. In the current case of Singapore, the particulate matter from forests being burnt, would be high in carbonaceous material and other residual matter from the sap of the trees.

In general, short term health effects from exposure to high pollution levels are eye, nose, throat and chest irritation, coughing, sneezing, runny nose and shortness of breath. Constant exposure to fine particles will also affect lung function, worsen medical conditions in existence such as asthma and heart disease and increase the risk of respiratory disorder in healthy people.

Those who exercise in an urban environment consistently where the PM reading is high, should really take considered and appropriate precautions. For example those who cycle for an average of 30 minutes to work at a brisk pace are likely to breathe approximately 1800 litres of air in that journey; without respiratory protection, that 1800 litres of contaminated air will be filtered by a cyclists respiratory system. That’s every day twice a day for two thirds of a year. Is there any wonder why people are looking to use masks to protect themselves.

Malaysia declares state of emergency in Muar and Ledang

Malaysia’s government on Sunday declared a state of emergency in two southern districts choked by smog from forest fires in Indonesia as air pollution levels reached 16-year-highs.

Environment minister G. Palanivel said the air pollutant index (API) hit 750 – a 16-year high for Malaysia – in the town of Muar on Sunday morning, with two other towns also reaching hazardous levels.

“The prime minister has signed a declaration of emergency for Muar and Ledang districts,” Palanivel told AFP in a text message.

Haze is an annual problem during drier summer months, when westerly monsoon winds blow smoke from forest fires and slash-and-burn land-clearing on the Indonesian island of Sumatra across the Malacca Strait to Malaysia and Singapore.

Malaysia’s API indicated that the capital Kuala Lumpur was also experiencing “unhealthy” air which has limited visibility to one kilometre, according to Palanivel.

The highest ever API reading was 860 during the 1997-1998 haze crisis that gripped the region.

An emergency was declared in 2005 when readings soared above 500.

Hundreds of schools have been closed since Thursday in Muar, which has a population of about 250,000.

Many Malaysians have begun wearing face masks as a precaution as the pollution levels have climbed.

The annual haze problem is blamed by Indonesia’s neighbours for affecting tourism and public health.

Singapore and Indonesia have lashed out at each other in recent days after the smog hit “critical” levels which the island-state said was potentially life-threatening to its ill and elderly.

Indonesia’s government has outlawed the use of fire to clear land, but weak enforcement means the ban is largely ignored.

Indonesia, meanwhile, has blamed Malaysian and Singapore-based palm oil companies for allowing slash and burn on estates they own on Sumatra.

The haze hit its worst levels in 1997-1998, costing Southeast Asia an estimated $9 billion from disruptions to air travel and other business activities.

Singapore mulls legal action over smog from Indonesia fires

Officials in Singapore say they are exploring whether to charge two Singapore-based companies in connection with severe smog triggered by forest fires in Indonesia.

The companies own land on the Indonesian island of Sumatra.

Singapore’s foreign minister said he had asked the attorney-general to consider the legal options.

However, he said it was mainly up to Indonesia to take action against the companies.

The firms, Asia Pacific Resources International (April) and Sinar Mas, are headquartered in Singapore but have Indonesian owners.

“The majority of hotspots in Riau (province) are inside April and Sinar Mas concessions,” Indonesian presidential aide Kuntoro Mangkusubroto told Reuters news agency.

Asia Pacific Resources International has issued a statement to the BBC denying the allegations.

Pollution has reached record levels in Singapore as a result of the smoky haze, affecting millions of residents.

Correspondents say the fires come from illegal burning in Sumatra that takes place in the dry season to clear space for palm oil plantations.

Foreign Minister K Shanmugam also said he would bring up the issue at a meeting of South-East Asian Nations (Asean) taking place in Brunei next week, and he has not ruled out appealing to other international bodies.

A senior official in the Indonesian president’s office said fires had been spotted on land owned by 32 companies in the region, some of them based in Malaysia and Singapore.

Schools in parts of Malaysia and Indonesia have closed temporarily.

Singapore’s Prime Minister Lee Hsieng Loong warned on Thursday that the haze could remain for weeks.

The Pollutant Standards Index (PSI) hit 401 at 12:00 on Friday (04:00 GMT) – the highest in Singapore’s history.

On Saturday at 10:00 local time (02:00 GMT) the PSI was at 326 – a level still considered hazardous.

UN concerns with the deteriorating air quality in Southeast Asia

As the blanket of haze, emanating from Indonesia, covers Singapore and Malaysia, the United Nations has been aroused to call for swift remedy to improve the air quality in Southeast Asia.

Reacting to the record high levels of smog that has descended across many Southeast Asian cities, a senior U.N. official has urged governments in the region to take effective and urgent action to tackle the serious challenges posed by the deteriorating air quality that is also having an impact on the health of the people that live there.

Noelen Heyzer, the executive secretary of the Bangkok-based U.N. Economic and Social Commission for Asia and the Pacific (ESCAP), observed that the current problem of air-pollution between Indonesia and Singapore was “symptomatic of a much wider challenge for the (region’s) countries.”

She called on the governments in the region to give priority to the issues of air quality and human health.

“Cross-boundary pollution is politically complex, but it must be urgently addressed. We need more effective frameworks to manage ecosystem services, such as air and water, which transcend administrative and political boundaries,” she said.

Adding that such matters were regional issues which must be tackled at the regional, as well as national and local levels.

According to ESCAP, the toll in terms of lives lost through pollution caused by vehicles, industries and energy-production activities in Asian cities is heavy, with an estimated 500,000 premature deaths occurring each year.

With over 1.7 billion people in the Asia Pacific region depending on dung, wood, crop waste and coal to meet their basic energy needs, indoor air pollution from solid fuel use is considered to be one of the causes for over 1.6 million deaths, with fatalities particularly among women and children being high.

Heyzer emphasized that health was the “single most important enabler of development”, and it was important to build a more sustainable region by prioritizing the prevention of “pollution of our air, water, food and other common regional goods”.

She cautioned the futility of making investment in healthcare systems and, yet, at the same time destroying the most basic environmental resources on which human health depended.

Carbon dioxide emissions had dominated regional and global air quality discussions in the context of increasingly severe climate change, reminding that one of the most serious and directly damaging issues of air pollution, especially in the rapidly urbanising region, is the concentration of particulates, which greatly increases the risk of heart and lung diseases and cancers.

“Our commitment to sustainable development in Asia and the Pacific will ultimately stand or fall on our response to these issues,” she said, and added that through strengthening existing mechanisms, and through inclusive intergovernmental platforms, such as ESCAP, that the challenges could be best addressed to the benefit of all the people of the region.

Singapore air pollution hits record high

Air pollution in Singapore has soared to a record high for a third consecutive day, as Indonesia prepares to send planes and helicopters to battle the fires blamed for hazardous levels of smoky haze in three countries.

The blazes in peat swamp forests on Indonesia’s Sumatra island have sent massive plumes of smog across the sea to neighbouring Singapore and Malaysia, both of which are growing impatient with Indonesia’s response to the problem that occurs nearly every year.

Singapore is suffering its worst haze in history. Its main index for air pollution hit a measurement of 401 at midday on Friday, exceeding record highs of 371 on Thursday and 321 on Wednesday. Those measurements were classified as hazardous and could aggravate respiratory ailments.

Plagued by the stifling smell of burning vegetation that wafted into homes and offices in this wealthy city-state, residents flocked to pharmacies to buy protective face masks after Singapore’s prime minister, Lee Hsien Loong, urged people to remain indoors.

“I don’t know if it’s just my imagination, but even indoors my throat is starting to feel weird,” said business manager Tan Joa-Quim. “I want a mask but my company has a limited supply, which we prioritised for the older and less healthy staff, and a lot of shops have sold out.”

The dirty, acrid haze has slashed visibility and shrouded many of Singapore’s landmarks, forcing airports to take extra precautions, the military to reduce outdoor training and some fast-food businesses to suspend delivery services.

Singapore’s environment minister flew to Jakarta, the Indonesian capital, on Friday to discuss measures to tackle the forest fires that break out in Indonesia during midyear dry spells because of carelessly discarded cigarettes and illegal blazes set by plantations and farmers to clear land.

Indonesia’s national disaster management agency said it planned to use two helicopters in a water-bombing operation to assist more than 100 firefighters on the ground.

It added that planes would be sent over parts of Sumatra in the next few days in a cloud-seeding effort to try to chemically induce rain.

Some airports in Sumatra have also closed because of poor visibility and pollution levels that exceeded Singapore’s.

In neighbouring Malaysia, officials closed nearly 600 schools in southern districts near Singapore. Most of the country, including the main city, Kuala Lumpur, was not as badly affected, though two southernmost towns recorded hazardous air quality.

This week Singapore’s environment minister, Vivian Balakrishnan, urged Indonesia to take urgent and definitive action to combat the pollution at its source. But some Indonesian officials suggested that Singaporean and Malaysian firms involved in Indonesian plantations might be responsible for several of the fires.

New pollution high as haze chokes Singapore

Pollution levels reached a new record high for a third day in a row in Singapore, as smoky haze from fires in Indonesia shrouded the city state.

The Pollutant Standards Index PSI hit 401 at 12:00 on Friday 04:00 GMT – the highest in the country’s history.

The haze is also affecting Malaysia, with another 100 schools closed in the south of the country.

Singaporean Prime Minister Lee Hsieng Loong warned on Thursday that the haze could remain in place for weeks.

“We can’t tell how this problem is going to develop because it depends on the burning, it depends on the weather, it depends on the wind,” he said.”

It can easily last for several weeks and quite possibly it could last longer until the dry season ends in Sumatra which may be September or October.”

A PSI reading above 300 is defined as “hazardous”, while Singapore government guidelines say a PSI reading of above 400 over 24 hours “may be life threatening to ill and elderly persons”.

Healthy people [may also] experience adverse symptoms that affect normal activity,” the government says.

Singapore resident Nicole Wu told the BBC that she had stayed indoors for the past two days.”It’s terrible. In my flat the windows are all closed with the air conditioning on,” she said. “My mother has to wear a mask to go shopping.”

“I can’t even see what’s happening outside my house due to the smog. You can’t see birds [or] moving objects,” she added.

Philip Koh, a doctor, told AFP news agency that the number of medical consultations he had had in the past week had increased by 20%.

A general view of the causeway from Singapore to southern Malaysia is obscured by haze on 21 June 2013 Air traffic controllers have been told to exercise caution given the poor visibility”

My patients are telling me they are worried about how long this is going to last and how much higher this is going to go,” he said.

Singapore’s National Environment Agency has started providing hourly PSI updates on its website, in addition to the three-hourly updates it previously provided.

Around 300 schools in southern Malaysia have now been closed as a result of the smog. Schools in Singapore are currently closed for the holidays.The fires are caused by illegal slash-and-burn land clearance in Sumatra, to the west of Singapore.

The smog has strained diplomatic relations between Singapore and Indonesia – two countries that usually share good relations, the BBC’s Karishma Vaswani in Jakarta reports.

Mr Lee said Singapore had provided satellite date to Indonesia to help it identify companies involved and said that if any Singapore firms were involved, that would be addressed.

Indonesia says two helicopters with cloud seeding equipment were deployed early on Friday to try and create artificial rain to put out the fire, AFP reported.

Indonesian President Susilo Bambang Yudhoyono said “all the country’s resources” would be mobilised to extinguish the fires.
