Urban vegetation can react with car emissions to decrease air quality in summer (Berlin)

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.

Three-quarters of all human releases of mercury have occurred since 1850

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.

Effects of air pollution on Mediterranean plants could be studied with reflectance spectroscopy

A technique called reflectance spectroscopy is the subject of a new literature review focusing on the use of this tool to study the effects of air pollution on vegetation. In particular, the researchers suggest that the technique could be more widely applied in the Mediterranean region, to study the effects of climate change and air pollution, which will be detrimental to crop growth as well as other vegetation. It could also be used as a more general biomonitoring technique for assessing pollutant levels in the environment.

Agricultural pesticides found in small streams in Germany

Small streams are important refuges for biodiversity, yet knowledge of the effects of agricultural pesticides on these freshwater bodies is limited. Researchers have used national monitoring data to determine the number of small streams in Germany where regulatory acceptable concentrations (RACs) of pesticides are exceeded. An analysis of data covering almost 500 pesticides and over 2 000 small streams suggests that agricultural land use is a major contributor of pesticides to streams. Overall, RACs were exceeded at 26% of sampled streams, and exceedances were 3.7 times more likely if a stream was near agricultural land. This finding may have implications for environmental monitoring and agri-environmental measures.

How to control and mitigate the effects of pollution on public health: Six Lancet Commission recommendations

Pollution is the world’s largest environmental cause of disease and premature death. The Lancet Commission on pollution and health brought together leaders, researchers and practitioners from the fields of pollution management, environmental health and sustainable development to elucidate the full health and economic costs of air, water, chemical and soil pollution worldwide. By analysing existing and emerging data, the Commission reveals that pollution makes a significant and underreported contribution to the global burden of disease, particularly in low- and middle-income countries. The Commission also provides six recommendations to policymakers and other stakeholders looking for efficient, cost-effective and actionable approaches to pollution mitigation and prevention.

Concern over health effects of air pollution linked to personal and environmental factors in seven European cities

Subjective perception of air pollution can have important implications in terms of health-protective behaviours and citizen and stakeholder engagement in cleaner-air policies. A recent study, conducted under the EU-funded PASTA1 project, has analysed the link between level of concern over health effects of air pollution and personal and environmental factors in seven European cities. Overall, 58% of participants were worried over health effects of air pollution, with large differences between cities. On a city scale, average levels of concern over health effects of air pollution had a good correlation with average NO2 levels and a lower correlation with average PM2.5 levels. Individual level of concern was found to be linked to gender, having children in the household, levels of physical activity, and NO2 levels at the home address. These findings can be used to inform future policymaking.

Innovative seaweed-based gel coating for urban homes able to capture harmful air particles

Air pollution via small particulate matter (PM) from diesel fumes and other sources is of growing concern in urban areas, and contributes to poor air quality. In European urban areas, PM pollution often exceeds World Health Organization (WHO) safe levels for human wellbeing. In response to this, the European Commission has encouraged researchers to develop a low-cost, sustainable material that captures these particles in order to clean the air1. This study created a new PM capture material using sustainable chemical processes where the carbon footprint and energy use of the production process of the remediation material is taken into account. The newly developed porous material is called ‘SUNSPACE’ (an acronym derived from ‘(SUstaiNable materials Synthesized from By-products and Alginates for Clean air and better Environment’).

Air quality co-benefits for health and agriculture outweigh costs of meeting Paris Agreement pledges

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.

PAH levels in Arctic air remain steady despite decreasing global emissions

Polycyclic aromatic hydrocarbons (PAHs) enter the environment in large quantities via the combustion of fossil fuels and organic matter. They are a cause for concern given their known toxicity, potential to cause cancer and ability to move large distances in the atmosphere — meaning that they are found in remote or protected areas, such as the Arctic, even if not emitted there. This study explores how PAH levels in the Arctic atmosphere have changed over the past 20 years at three sites in Canada, Norway and Finland. The results show that, despite a global decrease in PAH emissions in the same timeframe, the air concentrations in the Arctic are not significantly declining — possibly partly as a result of local warming causing more volatile PAHs to move from the surface to the air.

New energy-positive waste-water treatment process uses just 15% of the energy required for current alternative

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.
