Greener cities and more exercise could dramatically reduce urban mortality rates

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.

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.

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.

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.

Vegetative Vigour Terrestrial Plant Test adapted for assessment of atmospheric pollution

It is important to understand the extent to which atmospheric (air) pollution damages plants (i.e. its phytotoxicity) as well as the wider ecosystem (i.e. its ecotoxicity). For this reason, researchers have adapted the Organisation for Economic Cooperation and Development (OECD) Vegetative Vigour Test1 for the assessment of the ecotoxicity of samples of aerosol (suspensions of fine solid particles or liquid droplets in air). Typically, the test involves spraying the trial liquid on above-ground portions of the plant, such as the leaves. The adapted protocol involves extracting water-soluble aerosol compounds from aerosol samples to spray on the plant. The new protocol is sensitive enough to determine phytotoxicity and establish a clear cause–effect relationship, and as such has the potential to serve as a useful tool for the assessment of the effects of air pollution on environmental and human health.

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’).

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.

Precautionary Principle: decision-making under uncertainty – September 2017

One of the greatest challenges facing today’s environmental policymakers is how to deal with complex risks, such as those associated with climate change. These risks are difficult to deal with because they are not precisely calculable in advance. Where there is scientific uncertainty about the full extent of possible harms but ‘doing nothing’ is also risky, decision-makers may use the precautionary principle. This Future Brief explores the role of the precautionary principle in EU law and policy, and examines key points of discussion drawn from the evidence.

‘Cooling-off effect’ causes public perception of novel environmental technology to improve over time

Researchers have published a paper providing evidence that a ‘cooling-off effect’ can lead to increased public acceptance of new environmental technologies over time. The scientists analysed survey results from over 1 000 respondents in Germany, using solar radiation management (SRM), a controversial climate-engineering technique, as a test case. They found that, following a cooling-off period of either one month, 12 months, or 18 months, acceptance of SRM increased significantly — and that the longer the cooling-off period, the larger the increase. These findings have far-reaching implications, both for the deployment of SRM and for climate policymakers seeking to more accurately measure the public acceptability of novel interventions.

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.

How can ‘omics’ technologies – which enable large-scale, speedy biological data analysis – improve environmental risk assessment and management?

High-throughput ‘omics’ technologies, which allow exact and synchronised study of thousands of DNA, RNA, proteins and other molecules, are rapidly becoming more advanced and affordable. As these technologies develop, it is becoming quicker, easier and more affordable to generate unprecedented amounts of biological data, much of which could usefully inform environmental management. So far, however, the application of omics information in environmental management has failed to keep pace with the rapid development of omics-based research, meaning there is untapped potential. A recent study highlights the value of bringing omics information into environmental management and outlines practical ways in which omics can contribute to the risk assessment and management of chemicals.
