Pollution from agricultural pesticides can present a serious threat to aquatic ecosystems. Researchers have now developed a guide to identify the most appropriate measures to reduce pesticides entering waterways. It focuses on reducing pesticide entry via spray drift or runoff.

Silver nanoparticles are toxic to common bacteria at concentrations found in many aquatic environments across the globe, new research has found. Bacteria often form a key part of ecosystems and these impacts may be felt by the entire system, the researchers warn.

The combined effects of pollution and rising levels of atmospheric greenhouse gases, including CO₂, may have effects on marine ecosystems that are more damaging than expected, warns new research. The study found that bacteria capable of breaking down oil pollution were far less abundant in sediment in acidified waters. Although increased ultraviolet-B (UV-B) light reduced these negative impacts, the researchers caution that deeper waters or other waters with less UV-B, may still suffer.

Petrochemical lubricants have toxic effects on Antarctic seafloor ecosystems even after five years of degradation, a new study suggests. Examining the impacts of a standard lubricant and one marketed as biodegradable, the researchers were able to show that algae, which form the basis of the food chain, remained affected even after five years. Furthermore, the biodegradable lubricant appeared to provide no environmental benefits, as it had greater impacts in the long term.

The economic benefits of the ecosystem services provided by constructed wetlands far outweigh the costs of maintaining them, new research has confirmed. Analysis of a wetland that treats the third largest lake in Florida, US, shows that it provides ecosystem services worth $1.79 (€1.64) million per year, against costs of less than half that figure.

Researchers have presented a comprehensive new classification manual of asbestos-containing products (ACP), materials (ACM) and waste (ACW) in a recent study. They also mapped suitable landfill sites for the proper disposal of ACW in Italy and developed guidance on assigning ACW to correct European Waste Catalogue (EWC) codes. The research will help operators engaged in asbestos waste disposal across Europe and should contribute to aims for the total removal of asbestos from the EU.

The pathways for removal of dissolved phosphorus within biofiltration systems have been examined in a new study. Over 95% of phosphorus was removed over the study period, with the majority of phosphorus stored within plants. The researchers say the findings demonstrate the value of using suitable plant species within biofiltration systems to treat polluted water.

A new study shows that run-off from de-icing road salts can affect freshwater aquatic ecosystems by increasing certain types of plankton. The study is the first to compare effects of the most popular road salt, sodium chloride, with the effects of alternative salts and additives used to increase de-icing efficiency. Based on their findings, the researchers recommend that magnesium chloride and salt additives are used cautiously near water bodies.

For the first time, researchers have quantified the link between heat waves, the removal of ozone from the atmosphere by vegetation, ground-level ozone concentrations and its impact on human health and ecosystems. They found that high ozone levels, enhanced by effectively ‘turning-off’ the loss of ozone to the vegetated surface, could have caused around 460 extra deaths during a UK heat wave in 2006. In contrast, the heat wave protected ecosystems from ozone damage as plants absorbed less ozone from the atmosphere.ozone damage as plants absorbed less ozone from the atmosphere.

European emissions of sulphur and nitrogen pollution have fallen greatly in recent decades, a new report shows. However, even at present levels they harm sensitive ecosystems, and will continue do so for some years to come.
