Halving meat and dairy consumption in Europe could reduce agricultural greenhouse-gas emissions by up to 42% and nitrogen pollution by 40%, new research suggests. The amount of land needed to grow food for each EU citizen would fall from 0.23 to 0.17 hectares and the reduced intake of saturated fats and red meat could have substantial health benefits, the researchers conclude.

Cyanobacteria — often referred to as blue-green algae — are found in water bodies around the world and can produce toxins with potential health risks. This US-wide study found a significant positive association between cyanobacterial bloom coverage and death by non-alcoholic liver disease. The researchers say their study suggests some evidence of a potential health risk and should be used to generate further investigation into the health impact of cyanobacteria.

Intersex fish, in which male reproductive tissues become ‘feminised’, are increasingly being identified. This effect has traditionally been attributed to birth-control medications. This study exposed fish to a widely prescribed anti-diabetic, metformin. Male fish developed female sexual characteristics and reproductive rate decreased, which suggests that metformin may be a non-traditional endocrine-disrupting compound.

A methodology for assessing ‘chemical footprints’ has been developed by researchers to evaluate human pressures and the impact of chemicals released by the production and consumption of goods. The study integrates a life-cycle approach with different methodologies, such as those developed in the context of environmental risk assessment and sustainability science, with the aim of assessing the extent to which chemicals impact on ecosystems beyond their ability to recover (i.e. surpass planetary boundaries).

Nitrogen and phosphorus pollution change the relationship between the tropical coral Stylophora pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral.

Growing sugar beet varieties which are resistant to their pest, the cyst nematode, is the best way to achieve high sugar yields in northern Germany, recent research has concluded. The researchers say this method is better than growing trap crops or using pesticides to control the pests.

Pesticide-related poisonings in EU Member States must be reported to the European Commission under current legislation, but there is no standard information collection and reporting system. A new system has been proposed, which harmonises data collection, categorisation and reporting, enabling exposure data to be compared among Member States. The new system would improve the monitoring of pesticides in Europe and aid the identification of emerging problems.

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.

Reductions in air pollution in European cities significantly reduce the number of premature deaths, according to researchers. However, these results need to be communicated effectively to policy makers in order to have an impact.

A recent study has compared the impact of future power generated from large, central stations with power generated from smaller distributed generators (DG) in California on air quality. It concluded that although DG produces more emissions, its impact on air quality is likely to be smaller than central power stations due to complex interactions between air chemistry and transport.

Living near busy roads is associated with an increased risk of childhood leukaemia, according to French researchers. The study found that children living within 500 metres of major roads were more likely to develop leukaemia than those who lived far from such roads. It is possible that high levels of traffic pollution from the roads are responsible for the higher rates of the illness.

Airborne particulate matter pollution leads to increases in death rates among people with underlying health conditions such as heart disease, according to a new study. The study suggests the effects are mainly related to the air pollution known as PM_{2.5 - particles smaller than 2.5 micrometres (μm). The study is the first to assess the health effects of this type of pollution across several European countries at once.}

Long-term exposure to air pollution may increase the risk of developing type-2 diabetes, a Swiss study has found. The results also suggest that the association between type-2 diabetes and air pollution occurs at concentrations below World Health Organization (WHO) air quality guidelines.

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.

Long-term exposure to traffic-related air particle pollution is linked with type 2 diabetes, a new study in Germany has found. Furthermore, the study found that people living close to busy roads were at greater risk of developing the disease than those living further away.

European buildings built in the 1950s, 60s and 70s may contribute towards levels of toxins in the body, a new study suggests. Polychlorinated biphenyls (PCBs) were found at elevated levels in children that lived in houses and studied in schools built during this period, before PCBs were more thoroughly regulated in the construction industry. Although food is generally a more concentrated source of these toxins, the authors say exposure through these environments should be minimised wherever possible.

Flexible measures, such as pollen barriers, for regulating the cultivation of GM and non-GM crops in the same landscape are more likely to encourage the adoption of GM technology by farmers than rigid measures, such as isolation distances, according to a recent study.

Preserving biodiversity seems to reduce the emergence and spread of human diseases in many cases, according to an investigation into the links between biodiversity and human health. It concludes that there is mounting evidence indicating that preserving ecosystems in their natural state generally decreases the occurrence of infectious diseases.
