Polluted air is choking the city – Buses, cars are the main culprits

I couldn’t be the only one concerned about how increasingly polluted the ambient air around Kingston and St Andrew has become in recent times. Every other vehicle is spitting out thick, black smoke. One whiff of those vehicular emissions and my throat becomes sore, my head aches and my lips start burning – sure signs that the toxic emissions have just poisoned me.

These poisonous vehicular emissions consist of pollutants such as lead, carbon monoxide, suspended sulphates, nitrates, dirt, sulphur dioxide, nitrogen dioxide and soot. Drive around town with your windows down at your own risk.

Public transport vehicles, especially taxis, minibuses and the Jamaica Urban Transit Company (JUTC) buses, seem to be the worst offenders. They spew out the thickest, blackest smoke around town. Don’t the authorities, supported with taxpayers’ money, drive on the roads too and see and smell the pollution?

I sent some questions last week to Reginald Allen, JUTC’s corporate communications manager. He said that the problem of vehicular emissions “is definitely of concern to the JUTC, as we are aware of the health concerns relative to excessive emission into the atmosphere”, and he further indicated that “the intricate issue that relates to this problem is the high sulphur content that exists in our diesel fuel locally, which is 5,000 parts per million (5,000 PPM)”.

Thousands in southern Taiwan petition for better air quality control

Thousands of residents from southern Taiwan have petitioned online for the Legislature to pass an amendment to the Air Pollution Control Act to enable better air quality management, environmentalists said Thursday.

About 7,200 residents from Pingtung County and Kaohsiung City have joined the signature drive, which asks the Legislature to pass an amendment that requires the Environmental Protection Administration (EPA) to adopt a total volume control mechanism on air pollutants, according to Citizen of the Earth, Taiwan, organizer of the petition.

The mechanism will help local governments better control air quality, Wang Min-ling, deputy secretary-general of the environmental group, said at a press conference.

The petition also asks local weather channels to broadcast air quality daily to help citizens better prepare themselves for hazy days, she said.

The severity of air pollution in southern Taiwan is illustrated in a recent survey conducted between January and October this year, Wang said.

The survey showed air monitoring stations in southern Taiwan recorded a high level on the Pollutant Standards Index more often than other areas of the country, Wang said.

Air pollution in Prague starts crossing yearly quotas

Dust-related air pollution has crossed the yearly quota in some parts of Prague, mainly due to motor vehicles exhaust fumes, which leads to increased numbers of the diseases of lungs and the cardiovascular system and consequently to a higher death rate, Miroslav Suta has told CTK.

Suta, from the Environment and Health Centre, said low-emission zones that limit the entrance of high-emission motor vehicles would help Prague.

“These zones have proved themselves mainly in Germany and Denmark, but they are also established in several other countries. Prague has decided to have a feasibility study made,” Suta said.

He said the Prague City Hall set up a working group for the zones in the spring, but it has not met since.

Suta said the introduction of the toll would also help Prague. Now, Prague has zones from which lorries above 3.5 and six tonnes and buses are banned.

Suta said a part of Prague inhabitants breathe dust-polluted air due to heavy road traffic more often than the permissible 35 days a year.

The situation in Prague crosses World Health Organisation (WHO) recommendations as well as valid domestic levels.

Airborne particles smuggle pollutants to far reaches of globe

airborne particles

Pollution from fossil fuel burning and forest fires reaches all the way to the Arctic, even though it should decay long before it travels that far. Now, lab research can explain how pollution makes its lofty journey: rather than ride on the surface of airborne particles, pollutants snuggle inside, protected from the elements on the way. The results will help scientists improve atmospheric air-quality and pollution transport models.

The results also show that the particles that envelop pollutants also benefit from this arrangement. The new study in Environmental Science & Technology shows that the airborne particles, made from natural molecules mostly given off by live or burning plants, last longer with a touch of pollutant packed inside. The pollutants are known as polycyclic aromatic hydrocarbons, or PAHs, and are regulated by environmental agencies due to their toxicity.

Lydney awarded £44,000 for air quality surveys

A town in the Forest of Dean with air quality issues has been given a cash grant to carry out traffic surveys.

Earlier this year, levels of nitrogen dioxide in Lydney were found to be above national safety levels.

The Forest of Dean District Council has received £44,000 from Defra to carry out traffic surveys and work up possible solutions for the town.

Environmental health officers applied for the money to help develop an Air Quality Action Plan for the area.

Councillor Martin Quaile said the authority was pleased with the amount of feedback it had received from a consultation into managing the problem of traffic emissions in High Street, Newerne Street and Bream Road.

Smartphones equipped with sensors to study EU air pollution

Environmental sensor-equipped, GPS-enabled smartphones are set to be used in researching possible adverse effects of chemicals exposure to the human body, in the EU’s biggest to-date investment into environmental health research.

The €8.7m Exposomics project sets out to study the potential hazards of chemical exposure to the body, while at the same time analysing blood and urine samples to determine risk factors and see whether a chemical fingerprint can be detected in bodily fluids.

“It has become clear that the diseases with the greatest burden, such as cancer, diabetes, heart disease and neurodegenerative diseases such as Alzheimer’s, are mainly caused by factors other than genetics. These are likely to include aspects of lifestyle and the environment, but the precise roles of different factors in causing diseases are not well understood,” said Professor Paolo Vineis, School of Public Health, Imperial College London.

The term ‘exposome’ refers to the environmental components affecting a person’s health over the course of their life time, including lifestyle factors and chemicals exposure.

“We are all exposed to low levels of environmental pollutants every day, such as diesel exhaust, tobacco smoke, and pesticides. It’s very difficult to assess the health effects of these exposures, because often there are no unexposed people to compare with,” Prof Vineis added.

In order to measure the exposomes, high-tech tools are being developed, particularly those focusing on air and water pollution during critical periods of life.

Delhi smog defies quick-fix solutions

As the spells of winter smog spur environmentalists to ring alarm bells, the Delhi Pollution Control Committee (DPCC) says it is working overtime to ensure that Delhiites breathe safer air.

DPCC Chairman Sanjiv Kumar says that the city’s smog cover hasn’t developed because of factors such as increased emissions from vehicles or mushrooming industries. Rather, the Capital has become a victim of weather phenomena that aren’t under its control.

“By our assessment the rate of pollution hasn’t increased,” says Kumar. “Our city doesn’t have any major industries that can contribute so much pollution. Nor has the emission from vehicles increased overnight.”

Till recently, Delhi was in the grip of a weather phenomenon known as ‘inversion’ and the problem was further compounded by the air pollution travelling to the city from elsewhere.

‘Inversion’ is a weather phenomenon in which the air in an area remains confined within the city walls, with outside air unable to stir or disperse it. The stagnant air, like in an unventilated room, stays put until strong winds are able to scatter it away.

But such winds weren’t arriving in the Capital even as pollution from Punjab and Haryana was entering it, and the smog cover has thickened over the past few weeks.

Air quality alert issued for the area

The N.H. Department of Environmental Services is expecting air pollution concentrations to reach unhealthy levels for sensitive individuals in populated valley areas in southwestern New Hampshire — especially in Keene — for tonight into the late morning hours Wednesday.

State officials are calling for an Air Quality Action Day for this time and are advising sensitive individuals in the area to take precautions to protect their health by limiting prolonged exertion. Sensitive individuals include children, older adults and anyone with heart or lung diseases, such as asthma, emphysema, and bronchitis. Even healthy individuals may experience mild health effects and should consider limiting strenuous or prolonged activities.

The department forecasts concentrations of fine particle pollution to be unhealthy as the result of locally emitted pollution stagnating under temperature inversion conditions. Temperature inversions occur during calm, cold nights when warm air above traps cold air below. Such inversions prevent pollution near the ground from mixing with cleaner air aloft and diluting. As a result, ground-level pollution concentrations can increase. Much of locally emitted pollution comes from heating devices, especially residential wood burning stoves and boilers.
