Air pollution modelling could help predict algal blooms

Models that predict how nitrogen from the air is deposited in the sea could be useful in predicting algal blooms. Based on the knowledge that excess nitrogen increases algal growth rates, researchers simulated nitrogen deposition in the North Sea and suggested that, using predicted weather data, it might be possible to adapt this approach to predict algal blooms.

Air pollution linked to increased incidents of stroke

Exposure to gaseous and particulate matter pollution have been found to increase the immediate risk of stroke, a review of medical studies has shown. The increased risk is most pronounced the same day as the exposure, and for fine particles the increased risk persists over several days. The authors hope information from this study will help policymakers to develop suitable controls to limit the risks posed by these harmful air pollutants.

Long-term exposure to aircraft emissions causes premature death

As well as contributing to the greenhouse effect, aircraft emissions have an important impact on air quality and human health. This study, which quantified the effect of civil aviation emissions across the globe, suggests they could be responsible for 16 000 premature deaths every year, at an annual cost of over €18 billion. The air quality costs of aviation were similar to its climate costs, and over 10 times larger than accident and noise costs.

Travelling slower reduces fuel consumption and nitrogen oxides emissions of ships

Ships that reduce their speed use less fuel, which lowers costs for shipping companies. The slow steaming practice also cuts nitrogen oxides (NOx) emissions. A study found that ships travelling on four European routes lowered their NOx emissions by 12% during the economic crisis of 2008/2009. Shipping continues to be a major way of transporting goods, however, and as the global economy recovers the researchers and civil society call for additional measures to reduce NOx emissions from shipping and improve air quality in Europe.

Emissions from 2008–2015 VW diesel vehicles fitted with ‘defeat devices’ linked to 59 premature deaths

In September 2015, the United States Environmental Protection Agency (EPA) alleged that Volkswagen (VW) violated the US Clean Air Act by fitting ‘defeat devices’ in their light-duty diesel vehicles to falsify the results of emissions tests. According to a study assessing the potential impact of this decision, an extra 59 early deaths in the US are likely to be caused by exposure to PM2.5 and ozone.

Nitrous oxide could be removed from the atmosphere with simultaneous generation of renewable energy

Nitrous oxide (N2O) is a potent greenhouse gas and atmospheric pollutant. A new study proposes tackling both problems by removing N2O from the atmosphere using a combination of two innovative technologies — photocatalytic breakdown of the N2O to nitrogen and oxygen, and this within a solar chimney power plant that generates renewable electricity. Although some way off from commercial development, the researchers say this approach is feasible, and they outline how these two technologies can be integrated to reduce the climate impact and polluting effects of N2O emissions.

Nitrification inhibitors — climate change mitigation tool recommended by the IPCC – may be less effective than previously thought

Nitrification inhibitors are thought to mitigate climate change by reducing emissions of nitrous oxide — a potent greenhouse gas — from land. However, they may not be as effective as once thought, a new study suggests. The researchers found that, while inhibitors decrease emissions of nitrous oxide, they can increase emissions of ammonia — which is later converted to nitrous oxide. They recommend these effects are considered when evaluating inhibitors as a mitigation technology.

Policy responses should therefore consider uncertainty and sensitivity when developing measures to improve air quality.

Tackling mercury pollution in the EU and worldwide – November 2017

Mercury is a heavy metal that is well known for being the only metal that is liquid at room temperature and normal pressure. It is also a potent neurotoxin with severe global human health impacts. It can be converted from one form to another by natural processes, and, once released, actively cycles in the environment for hundreds to thousands of years before being buried in sediment. This In-Depth Report from Science for Environment Policy summarises the latest scientific studies and research results on mercury pollution in the global environment.

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.

Potential contamination of copper oxide nanoparticles and possible consequences on urban agriculture

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.

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.

Portugal’s air pollution levels to worsen, exceeding WHO guidelines by 2050

Air quality standards worldwide are facing increasing scrutiny as countries struggle to meet World Health Organisation (WHO) air-quality guidelines (AQGs), particularly regarding ozone (O3) and particulate matter (pollutant particles with diameters of less than 10 or 2.5 micrometres — PM10 and PM2.5 respectively). A new study aimed to evaluate whether WHO guidelines are being met in Europe; the researchers focused on Portugal, using recent data alongside climate change and background air pollution predictions. At present, Portugal frequently exceeds legislated values for ozone and PM10.

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.
