Ash from waste incineration can be made safer simply by mixing it with rice husks, water and other forms of waste ash at temperatures under 100 °C, according to new research. Once dried, the end product not only locks away toxic metals lead and zinc, but also stores carbon. Furthermore, it can be used in the polymer industry to lower costs, improve polymer properties and reduce the use of natural resources.

Aeration is an effective means of eliminating antidepressants from landfill leachate, a new study finds. The concentrations of five different drugs were reduced by this treatment process, which could be an effective means of tackling the growing problem of pharmaceutical infiltration into aquatic environments.

Chemical risk assessment and governance can be integrated and harmonised, but only up to a limit, albeit a variable limit, finds new research. The study’s authors examined the socio-political processes and factors surrounding integrated risk assessment and governance associated with chemicals in the EU. The research suggests there are opportunities for improvement if different views and implications of risk integration are considered through open communication and negotiations.

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 recent study has assessed the environmental impact of a group of technology-critical elements (TCEs) — niobium (Nb), tantalum (Ta), gallium (Ga), indium (In), germanium (Ge) and tellurium (Te) — that, to date, have been relatively under-researched. The researchers reviewed published concentrations of these elements in environmental archives and evaluated trends over time in surface waters. Overall, they found no evidence that the rising use of these elements in modern technologies is causing environmental concentrations to increase on a global level. These findings are relevant to future policy discussions regarding the source, usage and presence of less-studied TCEs, particularly in relation to critical raw metals.

Copper (Cu) is frequently used in agricultural practices, particularly in fungicides, used extensively in the management of permanent crops, such as vineyards, olive groves, and fruit orchards — all crops of significant economic importance to the EU. An investigation into the factors influencing Cu distribution in the topsoils of 25 EU Member States has identified that, in conjunction with other factors such as topsoil properties, land cover, and climate, such agricultural management practices play a role in influencing Cu concentration. The analysis used 21 682 soil samples from the EU-funded Land Use and Coverage Area frame Survey (LUCAS)¹ and found that vineyards, olive groves, and orchards had the highest mean soil Cu concentrations of all land use categories. The findings highlight the major impact of land use and agricultural practices on soil Cu concentrations and emphasise a need for more sustainable land management practices.

The presence and accumulation of micropollutants1 (anthropogenic trace contaminants) in aquatic environments is an area of policy concern for the EU. In order to better understand how these chemicals enter and are transported within water systems, this study investigated the occurrence and concentration of a broad spectrum of micropollutants across Austria’s water system. Municipal waste-water effluents were found to be the emission pathway with the highest concentrations of some micropollutants. The study also demonstrated that levels of other micropollutants are higher in rivers, atmospheric deposition and groundwater than in waste-water effluents and that these sometimes exceeded environmental quality standards for surface waters.

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.

Overall concentrations of some persistent organic pollutants (POPs) in soil have declined, according to research conducted in Norway and the UK. The researchers suggest that there has been a reduced influence of primary sources of some POPs on soils for these two countries in recent years.

Recently adopted EU waste legislation and its implementation at national level could have a significant effect on some countries’ emission loads for municipal solid waste incinerators, according to a recent study. The study suggests that the effects of increasing incineration over the next decade would be most profound for countries where incineration is currently only used on a small scale.

A recent global study has estimated that, each year, 1.5 million people die early from cardiopulmonary diseases and 0.1 million people die early from lung cancer caused by exposure to PM2.5 pollution. A further 0.4 million people are estimated to die early from respiratory diseases caused by exposure to surface ozone (O3) pollution. Although short-lived air pollutants have the largest influence on air quality and premature deaths, controlling methane emissions as well would improve air quality and reduce the number of people dying prematurely each year, the study suggests.

More Europeans are driving diesel cars, with important implications for vehicle emissions. A new study suggests that diesel cars may emit nitrogen oxides (NOx) at levels far higher than emissions standards, even when considering the newest generation of diesel cars. Part of the problem is that tests of vehicle emissions in the laboratory do not accurately reflect on-road emissions.

Nitrous oxide (N₂O) is a potent greenhouse gas and atmospheric pollutant. A new study proposes tackling both problems by removing N₂O from the atmosphere using a combination of two innovative technologies — photocatalytic breakdown of the N₂O to nitrogen and oxygen, and this within a solar chimney power plant that generates renewable electricity. Although some way off from commercial development, the researchers say this approach is feasible, and they outline how these two technologies can be integrated to reduce the climate impact and polluting effects of N₂O emissions.

A recent analysis highlights the potential of natural products as an indispensable source for drug discovery. Natural compounds can be used directly as potential medicines or can provide templates for the design of synthetic and semi-synthetic drugs. Furthermore, because of their ability to interact selectively with biological macromolecules, they also provide a tool to better understand biochemical processes and thus identify new potential targets for the treatment of human diseases.

Differences in the way wetland plants accumulate pollutants are helping researchers understand how vegetation can be used to help restore contaminated marshes. In a study by Belgian researchers, certain plants, including bulrushes, were identified as being potentially useful for locking away metal contaminants below the surface, thereby helping to reduce spread of these pollutants through food chains and to the wider environment.

An infrastructure offering high levels of quality and flexibility was required as a platform for a new system. Buying or renting new servers – and connecting and configuring them in short timescales – would be an expensive and challenging task. The IMV technical team turned to BT and asked whether it would be possible to set up the system in a virtual environment .
