Nanolithography — a way of making finely detailed patterns or structures, such as those found in advanced computer microchips, uses toxic and corrosive chemicals. Researchers have now shown that these could be replaced with eco-friendly silk proteins and water, eliminating the need to use and dispose of hazardous chemicals, while achieving similar levels of detail to conventional methods.

Phosphorus can be extracted in viable quantities from fly ash, a by-product created when municipal solid waste is burnt in incinerators, according to research conducted in Sweden. Sufficient phosphorus could be recovered from the country’s incinerators to meet 30% of the Swedish annual demand for mineral fertilisers, say the researchers.

Pharmaceutical pollution of marine environments has important biological consequences for aquatic organisms. This study investigated the effects on mussels of treatment with environmentally relevant levels of an antidepressant, fluoxetine, and a beta-blocker, propranolol, using biomarkers including DNA damage. The results showed that mussels are most vulnerable to these drugs in combination.

This study assessed the effects of herbicides on non-target plants in Denmark and Canada. The findings showed that some plants are more sensitive to herbicides in the reproductive stages of their life cycle and can experience delays in flowering and reduced seed production. The authors say future ecological assessments should consider reproductive outcomes.

The framework for a Europe-wide biomonitoring programme has been established by a new study. The preliminary investigation of 17 European countries showed that monitored levels of toxic chemicals varied significantly between countries. Although the levels were mostly within recognised health-based guidance values, in a few cases these values were exceeded. The researchers suggest that a fully-fledged European biomonitoring programme would help to develop policies to avert public health risks presented by environmental chemicals.

Weathering of treated wood and other construction materials can lead to the release of chemicals into the environment. Researchers have investigated the release of biocides from wood and roof paints, demonstrating that the amount of water in contact with exposed surfaces is a key factor in determining the level of active chemicals released. The study provides guidance for testing biocidal products in line with the European Biocidal Products Regulation.

Chemicals are everywhere and new substances are regularly being introduced to the market. However, only some pose a risk to the environment. How do we decide which of them to monitor? A new study using a database of chemicals found in fish in the Baltic Sea has assessed which chemicals are commonly monitored. The researchers suggest that monitoring is biased towards known, already regulated hazardous chemicals, and recommend changes to address other chemicals.

Researchers have developed a new approach to hierarchise pesticides based on their risk to or via the aquatic environment, which has been implemented in the Pinios River Basin of Central Greece. The analysis indicated that a number of pesticides were found in concentrations that could cause negative impacts on aquatic ecosystems. The results provide detailed information to inform decisions regarding the monitoring of pesticides in the Pinios River Basin and outline an approach that could be used in other watersheds.

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.

Soil biodiversity, soil quality, and soil health are integral to protecting the natural environment. Soils are crucial to food production and human well-being, as highlighted by the UN Sustainable Development Goals (SDGs). The abundance of soil biota is of great importance for the provision of associated ecosystem services (ES) and fundamental driver of self-regulation in soil. This study explores how the presence, or absence, of earthworms affects aspects of crop health and productivity, focusing on their shielding of winter wheat from the toxic plant fungi Fusarium.

Croatian researchers have developed new indicators that can be used to analyse photochemical pollution and smog caused by ozone. The indicators are based on simple mathematical formulae and could make it easier for those who monitor pollution levels to make meaningful comparisons between different sites.

The nitrogen dioxides (NOX) and carbon dioxide (CO2) emissions of some light-duty petrol and diesel vehicles are higher during on-road driving than during standard laboratory tests, according to a new study. This means that in normal on-road driving, light-duty vehicles, which include passenger cars and light commercial vehicles, may exceed European emissions limits and could be having a greater impact on urban air quality than previously thought.

Cutting mercury pollution could save Europe €8-9 billion per year by protecting children’s brain development, suggests a recent study. A third of babies in Europe are estimated to be exposed to unsafe levels of mercury before they are born, when in the womb, which may reduce their IQ and, in turn, restrict their educational and working achievements over their lifetime. This has long-term implications for society and the economy.

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.

The EU's Nitrates Directive has led to significant decreases in nitrogen pollution in Europe, a new study suggests. Modelled scenarios with and without implementation of the Directive showed that it had resulted in a 16% reduction of nitrate leaching by 2008. These improvements could be further increased as implementation becomes stricter, the researchers conclude.

The chances of a child developing Autism Spectrum Disorder (ASD) are higher if the mother is exposed to high levels of fine particulate air pollution during pregnancy, a recent study suggests. This increased risk was associated specifically with exposure in the last three months of pregnancy, the researchers found.

A recent analysis of tree-ring data spanning the past millennium reveals drought patterns that largely align with climate model projections for the same period. This adds credibility to climate models, which project that human influences on drought patterns will become stronger over the next century.
