Increased black smoke pollution was associated with increased mortality rates almost a month after exposure in a recent study. The researchers studied death rates in relation to pollution concentrations over a 22-year period in the city of Glasgow, UK, and found significantly higher mortality rates among residents at 13-18 and 19-24 days after increased exposure to black smoke.

Levels of the air pollutant PM_2.5 in Europe will continue to fall in 2020, concludes a recent study. Furthermore, deposition of nitrogen from air pollution will also drop. The outlook seems less positive for ground-level ozone, however, as large amounts of this pollutant continue drift over to Europe from other continents.

Real time monitoring of public health during two periods of high air pollution in the UK showed that there were an estimated 3 500 extra healthcare visits for acute respiratory symptoms and approximately 500 for severe asthma during these spells in 2014. The results of this research are presented in a new study which demonstrates the value of such ‘syndromic surveillance’ systems for exploring air quality’s effects on human health.

Emissions from well-regulated household waste incinerators do not reduce the quality of vegetables and milk produced nearby, a Dutch study suggests. Researchers found that levels of certain contaminants were similar whether vegetables and milk came from the area surrounding three incinerators, or from elsewhere in the Netherlands. They say biomonitoring programmes could offer a way to increase the understanding of the real impacts of waste incineration and to improve communication between waste management companies and local communities.

Hydrocarbons are precursors to hazardous air pollutants including ozone and particulate matter. Hydrocarbons from diesel make up over 50% of all hydrocarbons in the air in London, a new study has found. The authors also estimate that they contribute up to half of total ozone production potential in London, and say future air quality control strategies must focus more on these pollutants.

Health impact assessments (HIAs) provide information on the potential health impacts of policies, and are important for developing regulation on air pollution. In this study, researchers evaluated the metrics currently used in air quality HIAs to provide recommendations for their use in policy.

Research using the Environmental Quality Index (EQI) linked increased risk of preterm birth with poor air quality, but not with overall low environmental quality. The study is one of the first to explore the relationship between preterm birth and environmental quality across a range of different environmental domains (including water, air, land, built environment and sociodemographic aspects).

Different modelling approaches are used to design and assess air quality plans across Europe. This study assessed the strengths and weaknesses of these different approaches. The researchers conclude that a large variety of models is in use, without a preferred or standard model having emerged yet. They identify integrating local-scale and large-scale models and verifying models with measurements as the most important challenges.

Pollutants emitted by human activities have caused declines in air quality and drastic changes to climate. Despite being inextricably linked, these two major environmental issues tend to be viewed separately by policy. However, in certain instances, considering these issues together could lead to strategies that benefit both, according to a newly published review.

Researchers have estimated that, annually, almost 3 000 deaths (i.e. 20% of mortality) in Barcelona, Spain, are premature, and would be preventable if residents lived in urban environments that met international exposure recommendations for physical activity, air pollution, noise, heat and access to green spaces. The results emphasise the need to reduce motorised traffic, promote active and public transport, and provide adequate green space to encourage exercise and mitigate the impacts of environmental hazards in cities.

A recent study develops a framework for implementing IAMs using the Lombardy region of Italy as a case study. Researchers have run an uncertainty and sensitivity analysis with an environmental model, specifically with an Integrated Assessment Model (IAM) for air quality, demonstrating how model components are sources of uncertainty in the output of an integrated assessment. Policy responses should therefore consider uncertainty and sensitivity when developing measures to improve air quality.

Researchers have shown that emissions from vehicles can react with emissions from urban trees and other plants, resulting in a decrease in air quality in cities in summer; this reduces the otherwise positive impacts of urban vegetation. The study, conducted in Berlin, showed that during a July heatwave, 20% of ozone concentrations were due to emissions of volatile organic compounds (VOCs) from vegetation interacting with other pollutants. To reduce this effect, lowering emissions of these other pollutants is crucial.

A new study aimed at increasing knowledge of indoor air quality (IAQ) in recently built or refurbished office buildings has found that levels of pollutants are mostly within World Health Organization (WHO) air-quality guidelines, however they vary between seasons. In addition, some levels of particulate matter were found to exceed WHO guideline values. The OFFICAIR project was funded by the European Union's Seventh Framework Programme.

Ahead of the 2016 Paris Agreement on climate change, various climate and energy policy actions were proposed to target pledged 'nationally determined contributions' (NDCs). Now, researchers have quantified the global impact of implementing these actions on air quality, and determined that they have the potential to substantially reduce air pollution worldwide, with significant co-benefits for human health and agriculture — including the prevention of up to 99 000 premature deaths annually by 2030. These co-benefits could offset the global costs of climate policy; this study thus calls for an integrated policy perspective that aims to maximise the benefits of NDCs for climate and health.
