Mediterranean capital pollution has far-reaching effects on air quality

New research has modelled the impacts of Athens and Istanbul in the eastern Mediterranean, on local and regional air quality. Results indicate that the impacts of megacity pollution vary significantly according to the time of year and that air quality improvements will require coordinated efforts within the eastern Mediterranean region and beyond.

EU ship emissions directive improves air quality in harbours

To reduce air pollution levels in harbours, EU Directive 2005/33/EC requires all anchored ships to use fuels with low sulphur content. A recent study of air quality in Mediterranean harbours shows that levels of sulphur dioxide have decreased significantly since the Directive was implemented in 2010.

Air quality in Europe: pollution levels have dropped, but health concerns remain

Some progress has been made towards improving air quality in Europe with levels of sulphur dioxide, carbon monoxide and benzene all falling substantially in recent years, a new report from the European Environment Agency (EEA) concludes. However, threats to human health and ecosystems remain, and urban citizens’ exposure to high levels of particulate matter (PM) and ozone are a particular concern.

Black carbon pollution from megacities and effects on global air quality

Air pollution from the world’s megacities not only has local impacts, but can spread to remote regions of the world. Recent research has highlighted, for example, that megacities are a source of black carbon pollution in lowest kilometre of atmosphere in the Arctic, with European megacities contributing more than others.

European air quality in 2020: success story for PM2.5

Levels of the air pollutant PM2.5 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.

Fourteen days of poor air quality caused 4 000 extra healthcare visits in UK

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.

Air quality impact of diesel ‘severely underestimated’

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.

Air quality health impact assessments should use combination of metrics

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.

Poor air quality associated with increased risk of preterm birth

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).

Air quality assessment in the EU: room for improvement?

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.

Coordinated policies can benefit both air quality and climate change

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.

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.

OFFICAIR project finds seasonal variation in indoor air quality in modern office buildings

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.

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.

Lichen bioindication of biodiversity, air quality, and climate: baseline results from monitoring in Washington, Oregon, and California

Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results from the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) Lichen Community Indicator covering the first full cycle of data collection (1998-2001, 2003) for Washington, Oregon, and California. During this period, FIA conducted 972 surveys of epiphytic macrolichen communities for monitoring both spatial and long-term temporal trends in forest health. Major research findings are presented with emphasis on lichen biodiversity as well as bioindication of air quality and climate. Considerable effort is devoted to mapping geographic patterns and defining lichen indicator species suitable for estimating air quality and climate.

Did COVID-19 Improve Air Quality Near Hubei? -- by Douglas Almond, Xinming Du, Shuang Zhang

Ambient pollution is a byproduct of economic activity. It has been widely reported that COVID-19 and associated lockdowns have generated large improvements in air quality worldwide, including to China's notoriously-poor air quality. We analyze China's official pollution monitor data and account for the large, recurrent improvement in air quality following Lunar New Year (LNY), which essentially coincided with lockdowns in 2020. With the important exception of NO2, China's air quality improvements in 2020 are smaller than we should expect near the pandemic's epicenter: Hubei province. Compared with LNY improvements experienced in 2018 and 2019 in Hubei, we see smaller improvements in SO2 while ozone concentrations increased in both relative and absolute terms (roughly doubling). Similar patterns are found for the six provinces neighboring Hubei. We conclude that whether COVID-19 actually decreased pollution in China depends on the pollutant and reference period considered.
