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.

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 has, for the first time, estimated total anthropogenic releases of mercury over the last 4 000 years, up to 2010. Overall, the study estimates that a total of 1 540 000 tonnes of mercury have been released; three-quarters of this since 1850, and 78 times more than was released through natural causes over this period. Therefore, human activity has been responsible for a significant level of contamination, and this inventory can be used to inform and assess mitigation measures. The publication coincides with the ratification of the Minamata Convention on Mercury, and the new EU Mercury Regulation1, which prohibits the export, import and manufacturing of mercury-added products, among other measures.

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.

Researchers have assessed the phyto-toxic effects of copper nanoparticles on vegetables grown within urban gardens, comparing increasing doses of these nanoparticles to simulate potential aerial deposition to extreme pollution of CuO-NP in a range of increasing exposure periods. Lettuce and cabbage absorbed high amounts of copper nanoparticles, after 15 days of exposure, which interfered with photosynthesis, respiration and also reduced growth. Under the specific exposure conditions of the study the researchers indicate that metal nanoparticles could lead to potential health risks to humans from the contamination of crops from pollution.

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.

Although methods to assess the impact of genetically modified (GM) crops on terrestrial ecosystems are well defined, impacts on aquatic ecosystems have received less attention. A recent study has shown how the first step of an Environmental Risk Assessment could be applied in an aquatic environment, to assess the exposure of aquatic organisms to proteins in GM crops, using Bt maize as a case study.

Aquaculture is the fastest growing sector of worldwide food production and is facing a new era of expansion in Europe. What are the environmental implications of this, and can the sector expand sustainably? This Future Brief presents an overview of research into aquaculture’s impacts, and considers how it could develop in balance with environmental goals.

Conventional municipal waste-water treatment processes are based on aeration, which is energy intensive. Now, researchers have developed an alternative waste-water treatment process. In addition to avoiding the use of aeration in favour of filtration/biofiltration and encapsulated denitrification (the application of capsules containing nitrifiers, which convert ammonium into nitrate), the process also uses waste biosolids to generate electrical energy. The process has been tested in a pilot facility and found to require just 15% of the energy required for conventional approaches. Moreover, the process is energy positive, as the biosolids are able to generate more than enough energy to power the treatment plant. If this technology could be scaled up to the municipal level, it could significantly reduce the energy use and environmental impacts of waste-water treatment.
