Carbon nanotubes (CNT) could be released into the environment as the plastic they are embedded in degrades, a new study suggests. The research found that general wear combined with exposure to UV light and moderate humidity would expose CNTs, posing a potential threat to human health.

Mercury and persistent organic pollutants (POPs) reduce albatrosses’ chances of successfully breeding, a recent study finds. These pollutants add to the list of environmental pressures, including climate change, disease and fishery bycatch, affecting this highly threatened species.

Rodents poisoned by pest control substances may pose a threat to protected birds if the carcasses are not removed quickly enough. A new study found that dead water voles on farmland were scavenged rapidly by red kites and buzzards, suggesting that regular removal is needed to reduce poisoning risks.

Beetles that are helpful to farmers can be poisoned if they feed on slugs that have eaten crops treated with neonicotinoids, a new study reports. The slugs themselves are not harmed by neonicotinoids. In American field trials, researchers found that plots planted with neonicotinoid-treated soybeans contained more slugs, fewer beetle predators and had 5% lower yields. The insecticide may be reducing the beetles’ effectiveness as a natural control of slug pests.

Ocean acidification and eutrophication may affect the growth of microscopic algae - phytoplankton - with knock-on impacts for marine food chains and fisheries, warns a new study. By growing phytoplankton under different scenarios the researchers found that phytoplankton species are affected differently according to the acidity and nutrient content of the water.

The risk of eutrophication as a result of nitrogen and phosphorus pollution in Europe’s freshwaters fell by 22% in lakes and by 38% in rivers between 1985 and 2011, new research has shown. The researchers analysed data across 88 European river basins using a new statistical approach which could be used to help identify factors which increase eutrophication risks.

Halogenated nitrogenous disinfection by-products (N-DBPs) in water increase bacterial resistance to antibiotics, new research shows. The study found that a strain of bacteria which can cause disease in humans, Pseudomonas aeruginosa, increased its resistance to a range of different antibiotics by an average of 5.5 times after the bacteria were exposed to chemicals which form as by-products of common water treatment procedures. The results highlight the risks to public health which these currently unregulated by-products may cause.

Vermicomposting livestock manure with maize can increase agricultural benefit by 304%, shows a new study. The combination of increased crop yield and the additional earthworms produced as a result of the process led to a substantial increase in output compared to a traditional composting system.

Pesticides used on agricultural land can leach into nearby surface water; this is called run-off and can harm aquatic ecosystems. This study evaluated the potential of ditches to reduce run-off, using Italy’s Po Valley as a case study. Grassy ditches were able to significantly reduce the concentration of herbicides, even during extreme flooding. The researchers therefore suggest that the promotion of vegetated ditches via agri-environment schemes would be beneficial for pesticide mitigation.

Silver nanoparticles are used in a range of household products. This study investigated the risk to plants of these nanoparticles in soil, showing that risk was overall low but increased when soils contained high levels of chlorine. The researchers, therefore, suggest that the risk of silver nanoparticles to plants may increase in salty soils or those irrigated with poor-quality water. These findings could be important for future risk assessments.

European Atlantic countries are, in general, at higher risk of being affected by oil spills than Mediterranean and Baltic countries, with the United Kingdom most affected, according to new research. The study developed a new risk index for analysing the potential vulnerability of coastal regions to oil spills at sea.

A new study has mapped levels of chemical elements found in European agricultural soils. In most places, unusually high concentrations are linked to geology, such as high levels of arsenic in the Massif Central in France. Human activity is to blame in some small areas, for example high concentrations of mercury were found near London and Paris. Abnormal concentrations, both too low and too high, could pose an environmental risk. This new data can be used in conjunction with the REACH Regulation1 and can help identify areas where action may be needed in relation to toxic elements in the environment.

The presence of disinfection by-products (DBPs) in drinking water is an emerging health concern. DBPs come in many classes and are chemically diverse, making them challenging to monitor. Swedish researchers have evaluated a new method for the simultaneous determination of a broader range of DBPs than typically possible using other available techniques. The method uses gas chromatography (a laboratory technique that separates and analyses vaporisable compounds in a mixture), together with a halogen-specific detector (XSD). Having been tested in real water samples from two municipal waterworks in Sweden, the method has been optimised for the simultaneous determination of a wide range of neutral DBPs.

Sulphur and nitrogen emissions have been significantly reduced across Europe in recent decades, but a recent study from Sweden finds that some forest soils are still struggling to recover from the acidifying effects of the pollutants. Some areas are also at risk of nitrogen leaching from soils into surface waters.

Measures to control methane and black carbon (soot) emissions could improve air quality and public health, in addition to slowing the rate of climate change, according to recent research. By 2030, the reduced pollution could prevent between 700,000 and 4.7 million premature deaths each year, with 80% of the benefits occurring in Asia.

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.

New software has been developed to rate the health risks of different activities in the urban environment, for example, cycling or driving in different areas of a city. 'CENSE' is based on a variety of different pollutants and environmental health hazards encountered in urban environments and may provide a useful tool for urban planning and improving residents’ quality of life, its developers say.

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.

Fires in forests contaminated by the Chernobyl nuclear accident could lead to areas of Europe and Russia being exposed to further radioactive fallout, new research has found. The study examined the spread of the fallout and the health effects on people and animals under three different scenarios: 10, 50 and 100% of the forests being burnt.

Back in 1999, a group of scientists predicted how changing air pollution levels would affect the acidity of lakes and rivers in Europe in 2010 using a computer model. A follow up study has now gathered actual measurements of these waters to see if the predictions came true. The observations show that most of the rivers and lakes did recover from acidification, as forecast by the model, and demonstrate the model’s value in predicting future water chemistry, the authors say.

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.

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.

Bacteria taken from underground petroleum reserves could be used to effectively break down crude oil from spills at sea, new research has found. The study measured the breakdown of crude oil components in simulated seawater by four bacterial strains that had been isolated from petroleum reservoirs, as well as by four genetically modified stains. The findings raise the possibility of tailor-making organisms to clean up specific types of contamination.

The effects of antibiotic contamination may be attenuated by the common reed, new research shows. The study found that the common reed (Phragmites australis), sourced from a temperate estuary with brackish water, had capacity for the bioremediation of the veterinary antibiotic enrofloxacin (ENR). The authors suggest that salt-marsh plants and their associated micro-organisms could be a valuable asset in the recovery of contaminated estuary environments.
