According to most EU legislation, regulatory assessment of chemicals should make use of all available and relevant studies. However, in practice, assessments tend to be predominantly based on research sponsored and provided by industry as part of their legal obligations to show safety of their products, rather than on independent peer-reviewed findings. To bridge this science–policy gap, a team of Swedish researchers, in combination with regulators at three Swedish governmental agencies, have published a list of recommendations aimed at increasing the regulatory usability and impact of academic research. This advice is aimed at researchers, for whom it clarifies relevant regulatory data requirements and quality criteria. However, it is also relevant to policymakers, in that it highlights the advantages and availability of relevant, reliable peer-reviewed research for use in the regulatory assessment of chemicals. The study’s recommendations contribute to the formulation of more science-based, sustainable policies.

Environmental pollution is putting amphibians and reptiles at risk, yet these animals are not included in regulations regarding the environmental risk assessment (ERA) of pesticides. The extent to which other species already used in pesticide toxicity assessment (including fish, birds and mammals) can serve as effective surrogates is currently under debate. This study conducts a systematic review of the available literature. The results reveal a positive correlation between toxicity recorded on fish and aquatic amphibians, but indicate that birds and mammals are generally not good surrogates for reptiles and terrestrial amphibians. Moreover, some chemical-dependent trends were detected, with a number of insecticides found to be more toxic to amphibians or reptiles than to potential surrogates. These findings highlight an urgent need for further research to reduce uncertainties and contribute to future policymaking regarding the protection of amphibians and reptiles from potentially harmful pesticides.

PFASs — per- and polyfluoroalkyl substances — are a family of chemicals used in a wide range of industrial and consumer applications. Due to concerns about their persistence, bioaccumulation and toxicity, long-chain PFASs are increasingly being phased out, creating a growing market for alternatives. Researchers have developed a novel method, based on molecular simulation techniques, to estimate the rate at which novel PFASs interact and bind with particular proteins (‘binding affinity’) — an important factor in determining a substance’s bioaccumulation potential in organisms. The method indicates that replacement PFASs may be just as bioaccumulative as original (legacy) PFASs and are, therefore, not necessarily safer. If correct, this finding has significant policy implications.

Soil is an overlooked source of persistent organic pollutants (POPs) for grazing cows, finds a new study of contaminated farms in Switzerland. The researchers tested a new modelling tool to track two specific environmental POPs — known as polychlorinated biphenyls (PCBs) and dioxins (PCDD/Fs) — as they moved from the farm environment into a cow’s body over time. The tool could be used to assess measures designed to decontaminate animals or to prevent contamination, such as grazing regimes that aim to reduce the risk of cows eating soil accidentally.

Silver nanoparticles present in the effluent from waste-water treatment plants could have toxic effects on aquatic organisms, new research suggests. The lab-based study tested the effects of nanoparticle-containing effluent on several crustacean and algae species. The researchers observed that epibenthic crustaceans (those living in or on sediments at the bottom of water bodies) were the most sensitive; notably, a 20–45% higher death rate was observed compared with those exposed to nanoparticle-free effluent.

Assessing the impact of large urban areas on air quality and climate change needs an integrated approach with a range of spatial and temporal scales, according to researchers. The EU-funded MEGAPOLI project considers time scales from seconds to decades and spatial scales from local to global.

Using hydrogen as an energy carrier can help reduce air pollution and greenhouse gas (GHG) emissions associated with fossil fuels, according to recent research. However, if used on a large-scale, it is important that hydrogen does not leak significantly into the atmosphere as it might have some negative environmental effects, such as increasing the lifetime of methane, increasing climate effects and causing some depletion of the ozone layer.

Residents living within half a mile of unconventional natural gas wells may have an increased risk of illness from exposure to air pollution from the wells, according to a recent study. The peer-reviewed study recommends that risk prevention efforts to minimise impacts on human health should concentrate on communities living and working close to wells during well completions and that further studies on health effects of exposures to air emissions from such projects should be carried out.

City dwellers who grow their own fruit and vegetables may be consuming high levels of pollutants. In a recent study, researchers found that vegetables grown on plots in Berlin, Germany, often contained higher concentrations of some heavy metals than shop-bought vegetables, with those grown close to busy roads containing the greatest quantities.

Danish researchers have recently revealed that crop harvesting can release high levels of Alternaria fungal spores, affecting air quality locally and, occasionally, over long distances. The fungus is known to trigger human allergic reactions, and the study calls for improved monitoring and forecasting of airborne fungal spores.

Gas flaring and residential combustion are significant sources of soot, or black carbon, pollution in the Arctic, but their role has been underestimated until now, according to a recent study. The research indicates that flaring from oil and gas developments is the largest source of this pollutant, responsible for 42% of black carbon pollution in the Arctic.

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.

Particulate matter (PM) emissions from domestic wood burning in London are higher than the PM reductions achieved through London’s Low Emission Zone, finds a new study. The research suggests that increases in wood burning could risk undermining policies aimed at meeting EU PM₁₀ targets.

The net cooling effect that aerosols have on the climate will be lost as emissions drop in the future, new research suggests. However, the consequent warming will ultimately be counter balanced if policies to reduce greenhouse gas (GHG) emissions are put in place.

Pregnant women living within 16 km of unconventional gas wells in Colorado, US, are up to 30% more likely to give birth to a baby with a heart defect, new research has found. These findings suggest that more research is needed to understand the potential health impact of natural gas developments, say the researchers.

Emissions of the greenhouse gases (GHGs) tetrafluoromethane (TFM) and hexafluoroethane (HFE) reported by industry accounted for only around half actual levels measured in the atmosphere between 2002 and 2010, new research reveals. The semiconductor and aluminium production industries, the two main sources of these gases, have reported success in their voluntary efforts to control these emissions. However, this does not match ‘top-down’ atmospheric monitoring, the researchers say.

Setting cycle and footpaths further back from the road can significantly lower the amount of air pollution that cyclists and pedestrians inhale, suggests new research. While wide gaps are not always practical, the study shows that even small increases in distance could substantially reduce the dose of pollution.

Effective greenhouse gas (GHG) mitigation measures to stabilise global temperature change to no more than 2°C above pre-industrial temperatures would also substantially reduce air pollutant emissions, recent research predicts. A variety of mitigation options are available, including switching from fossil fuels to renewable sources of energy. To achieve the necessary GHG emission reductions, one key option is to impose carbon taxes. However, these would need to be high to help achieve this target, according to the study’s authors.

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.

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.

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.

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 PM_2.5 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.

Scientists have discovered a novel way to produce bioplastic, which could be more cost-effective on a commercial scale than current techniques. The new technique, which uses microscopic algae to synthesise a widely used polyester, has the potential to revolutionise plastic production, say the researchers.

Biogas production from waste and manure has the potential to make a contribution to environmental, energy and climate policy objectives. However, farmer engagement has remained persistently low. A new study, involving 461 Danish farmers, has investigated their willingness to participate in collective biogas investment (where two or more farmers collectively own a biogas plant). The study suggests that the majority of farmers are willing to participate in partnership-based biogas investment (PBI) and identifies the main factors driving willingness to participate and the intensity of participation. These findings are relevant to policymaking aimed at increasing biogas production and stakeholder engagement.
