High levels of pollution put children at the risk of getting viral/pneumonia infections 

Studies indicate that extended exposure to pollutants like particulate matter (PM2.5), nitrogen dioxide, and carbon monoxide can lead to systemic inflammation and metabolic disruptions, both of which play a significant role in weight gain.

The Centre and the States need to fight air pollution together 

Toxic smog has shrouded Pakistan's cultural capital of Lahore and 17 other districts in Punjab since October 2024.

Air pollution is costing advanced economies plus China and India an estimated USD 3.5 trillion a year in premature deaths and ill health and the costs will rise without government action to limit vehicle emissions, a new OECD report says.

Today’s post, marking World Environment Day, is from OECD Secretary-General Angel Gurría. Air pollution has become the biggest environmental cause of premature death, overtaking poor sanitation and a lack of clean drinking water.

The current Volkswagen diesel emissions scandal highlights the difficult reality of making the transition to a low-carbon economy. It also highlights the growing need for governments to make smart policies, based on actual costs.

Outdoor air pollution is a major determinant of health worldwide. The objective of this paper is to inform the development of improved estimates of the social costs of human morbidity impacts resulting from outdoor air pollution in two components; namely to develop a core set of pollutant-health end-points to be covered when estimating the costs of morbidity, and to review current estimates of the cost of morbidity from air pollution.

Outdoor air pollution could cause 6 to 9 million premature deaths a year by 2060 and cost 1% of global GDP – around USD 2.6 trillion annually – as a result of sick days, medical bills and reduced agricultural output, unless action is taken, according to a new OECD report.

Anyone else feeling exhausted by all this drum humming about air pollution? Indeed it appears the fumes won’t be dissipating any time soon as we consider the extent to which tyre and brake rubbish exacerbate the problem.

This paper presents updated results for the cost of ambient air pollution in 41 countries: the 6 major emerging economies known as the BRIICS – Brazil, Russia, India, Indonesia, China and South Africa – and the 35 OECD member countries.

Air pollution in Delhi has been so bad this November that the Indian Medical Association declared a public health emergency. According to the latest Global Burden of Disease study published in The Lancet, outdoor air pollution caused more than a million premature deaths in India in 2016, whose cost, according to OECD estimates, amounts to more than USD 800 billion.

Short-term exposure to current levels of ozone in many areas is likely to contribute to premature deaths, says a new National Research Council report, which adds that the evidence is strong enough that the U.S. Environmental Protection Agency should include ozone-related mortality in health-benefit analyses related to future ozone standards.

The U.S. Environmental Protection Agency (EPA) carries out experiments in which volunteer participants agree to be intentionally exposed by inhalation to specific pollutants at restricted concentrations over short periods to obtain important information about the effects of outdoor air pollution on human health.

The U.S. National Academy of Sciences and U.S. National Academy of Medicine joined the science academies of South Africa, Brazil, and Germany today in issuing a statement calling for urgent worldwide action to reduce air pollution.

Researchers have developed a new model to assess the health-related external costs arising from air pollution from ten major emission sectors. Applying the model at national and Europe-wide levels, they suggested that the major contributors to costs were industrial power production, agriculture, road traffic and domestic combustion.

The damaging health impacts of some key air pollutants can occur at lower atmospheric concentrations than indicated by the most recent World Health Organization (WHO) Air Quality guidelines, set in 2005 and currently used in Europe. This is according to a new WHO report, which assesses scientific evidence to help inform European air pollution policies.

Continued reductions in air pollution and greenhouse gas (GHG) emissions are essential, as they pose serious threats to both people's health and the environment across the world. Air quality and climate policies can provide mutual benefits and there can also be trade-offs. This thematic issue reports on research which helps us understand the relationship between air pollution and climate change and how the two policy areas can be integrated to produce the greatest results.

Residents living within half a mile of unconventional natural gas wells may have an increased risk of illness from exposure to air pollution from the wells, according to a recent study. The peer-reviewed study recommends that risk prevention efforts to minimise impacts on human health should concentrate on communities living and working close to wells during well completions and that further studies on health effects of exposures to air emissions from such projects should be carried out.

Periods of slow growth observed in coral reefs in the Caribbean are caused by aerosols in the air from pollution and volcanic activity, recent research suggests. Aerosols cause cooler sea surface temperatures and reduce the amount of sunlight reaching the coral, both of which slow coral growth.

Measures designed to reduce levels of methane and black carbon in the atmosphere could help bring climate change under control more quickly than CO2 targeting measures alone, according to a new study. The researchers also predict wider benefits for human health and food security from methane-targeted measures.

New research reveals that indoor air pollution is an important indicator of the impact of emissions from an oil refinery on nearby communities. It suggests policies based on outdoor monitoring alone are not sufficient to safeguard health, especially with regards to breast cancer.

A team of investigators has examined the effects of air pollution on human health using the databases of earlier studies from Europe, the United States and Canada. They concluded that PM₁₀ and ozone are associated with an increase in mortality. Different modelling approaches do not significantly affect the results.

Reductions in air pollution in European cities significantly reduce the number of premature deaths, according to researchers. However, these results need to be communicated effectively to policy makers in order to have an impact.

The 2010 deadline for the Gothenburg Protocol ceilings for transboundary air pollutants is fast approaching and new ceilings may soon be set for 2020. Recent research indicates that, although the ceilings have been effective, they could benefit from more flexibility to allow for the inherent uncertainty in modelling future energy use, technologies and growth.

Evidence from modelling studies suggests that climate change is likely to increase concentrations of ozone, one of the most important urban air pollutants responsible for respiratory problems. Under this assumption, rapid reductions of emissions from fossil fuel burning are needed to protect the health of both current and future generations.

Combining policies that tackle local air pollution and global climate change will deliver enhanced benefits for climate change mitigation, according to researchers. Medium-term efforts to control air pollution will provide additional benefits to long-term strategies that aim to curb climate change.

A new study has shown that life expectancy and monetary benefits increase significantly when levels of fine particles are reduced further in European cities. It also reveals that living near busy roads could be responsible for a substantial amount of poor health attributable to air pollution.

The quality of indoor air varies widely across Europe, according to a recent study. However, more data are needed from a range of locations, especially in towns and cities, and greater harmonisation of sampling and analysis procedures are needed to develop a more comprehensive picture of European indoor air quality.

Traffic fumes can cause serious health problems, but their distribution and spread in complex urban environments can be hard to predict. Now, researchers have created the ‘STEMS-Air dispersion model’, which can be used by planners and health authorities to give accurate daily and annual estimates of exposure to traffic fumes and other forms of air pollution in cities.

The quality of indoor air varies widely across Europe, according to a recent study. Poor indoor air quality is mainly due to household products, outdoor pollution and smoking yielding high levels of organic pollutants harmful to human health. The study indicates higher levels of indoor air pollution in southern Europe than in northern Europe, and with an associated risk of cancer higher than the acceptable unit risk. However the present data must be improved in order to get more precise risk estimates

A study in the Czech Republic has found a link between exposure to certain air pollutants and an increase in DNA damage for people exposed to high levels of the pollution. They found that breathing small quantities of a polycyclic aromatic hydrocarbon (PAH), called benzo[a]pyrene (B[a]P), caused an increase in the number of certain ‘biomarkers’ in DNA associated with a higher risk of diseases, including cancer.

A new report suggests that underground carbon storage projects in Europe could lead to positive and negative effects on air pollution, depending on the pollutant in question. Carbon capture and storage (CCS) is considered in European legislation as a ‘bridging technology’ – a medium-term solution to climate change. Although the overall air quality impact of CCS is expected to be positive, the legislation notes that the technology should not be seen as a replacement for commitments to developing a greener and more energy-efficient economy.

Scientists have created a new, easy-to-use tool that allows health professionals to monitor the day-to-day risks posed by short-term exposure to main urban air pollutants. The tool could enable vulnerable groups, such as asthmatics, to take precautionary measures and to increase public awareness of the health impacts of air pollution, say the researchers.

Residents living within half a mile of unconventional natural gas wells may have an increased risk of illness from exposure to air pollution from the wells, according to a recent study. The peer-reviewed study recommends that risk prevention efforts to minimise impacts on human health should concentrate on communities living and working close to wells during well completions and that further studies on health effects of exposures to air emissions from such projects should be carried out.

Planting vegetation in city streets could significantly reduce air pollution in urban street canyons, according to new research. Traffic pollutants are deposited on vegetation at a higher rate than on hard, built surfaces and could reduce the concentration of nitrogen dioxide (NO2) and PM10 in the air by as much as 40% and 60%, respectively, under certain conditions.

A new study has estimated that nitrogen oxide (NOx) and harmful ozone levels will fall significantly in Europe, by 2030, if all current and planned air quality legislation is implemented. The co-beneficial effects of climate change policies could also reduce levels of these air pollutants by a further 40%.

The damaging health impacts of some key air pollutants can occur at lower atmospheric concentrations than indicated by the most recent World Health Organization (WHO) Air Quality guidelines, set in 2005 and currently used in Europe. This is according to a new WHO report, which assesses scientific evidence to help inform European air pollution policies.
