Sparrowhawks and their eggs are used to assess environmental concentrations of polybrominated diphenyl ethers (PBDEs), chemicals that were used until relatively recently as flame retardants. Recent research may help explain why different studies report different PBDE levels in sparrowhawks for the same countries and time periods. It appears nutrition may play an important role in determining PBDE concentrations in birds.
Natura 2000 sites may not be adequately protected in Eastern Europe, according to a recent publication. Researchers in the Czech Republic found that, despite being designated as a Natura 2000 site, environmentally damaging activities continued in the Šumava National Park. They recommend that good environmental education is needed to help post-communist countries implement Natura 2000 and better recognise its value and importance.
Oil spills at sea can be catastrophic events, with oil and discharged toxins, including polycyclic aromatic hydrocarbons, threatening marine wildlife and coastlines, damaging healthy ecosystems and harming livelihoods. A recent study found that using dispersants moderately decreased the number of cod eggs and larvae affected by spills off the Norwegian coast.
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.
Chickens foraging on soils containing environmental pollutants can accumulate these chemicals in their tissues and eggs. This study assessed levels of dioxins in eggs produced in Poland, in some cases finding concentrations several times above the safe EU limit. The researchers identified the source as preservative-treated wood in the chicken coop, which they say is a public health risk.
A study of the pollution caused by ship scrapping in Alang, India, shows significantly higher levels of heavy metal and petroleum hydrocarbons in sediment and seawater, compared to a control site. The researchers also found reduced populations of zooplankton — a critical food source for marine biota — and increased numbers of pathogenic bacteria.
European policy permits the application of nutrient-rich sewage sludge on agricultural land as a means of recycling1. However, contamination of sludge with microplastics may pose a risk to ecosystems. This study looked at the characteristics of microplastics in sewage sludge after three types of waste-water treatment, finding that anaerobic digestion should be explored as a method of microplastic reduction.
Personal Care Products (PCPs) are of increasing global concern, as thousands of tonnes enter the environment every year. Similar to persistent organic pollutants (POPs), some substances used in PCPs are toxic, persist in the environment and accumulate in the bodies of organisms that take them in. This study focused on the presence of ultraviolet filters (UV-Fs) (used in PCPs such as sunscreens and cosmetics) in the unhatched eggs of wild birds.
PFASs — per- and polyfluoroalkyl substances — are a family of chemicals used in a wide range of industrial and consumer applications. Due to concerns about their persistence, bioaccumulation and toxicity, long-chain PFASs are increasingly being phased out, creating a growing market for alternatives. Researchers have developed a novel method, based on molecular simulation techniques, to estimate the rate at which novel PFASs interact and bind with particular proteins (‘binding affinity’) — an important factor in determining a substance’s bioaccumulation potential in organisms. The method indicates that replacement PFASs may be just as bioaccumulative as original (legacy) PFASs and are, therefore, not necessarily safer. If correct, this finding has significant policy implications.
Innovatively designed batteries offer a way for vehicles to move away from their dependence on fossil fuels. There has been little mass-market uptake of new battery design, however. In the last century, only four types of battery have been used: manganese oxide; lead acid; nickel; and lithium ion, which is a relative newcomer, introduced in 1991. To understand how innovation moves from research and development (R&D) to application and the mass market, scientists perform technology lifecycle (TLC) analyses, often focusing on R&D and basic research. This study adds an additional indicator — start-up companies — to explore the early phases of how batteries transition from science into industry.
Greater amounts of air pollutants emitted in East Asia will move around the globe under climate change, a recent study predicts. Changes to wind speeds and air pressure will mean that movement of pollution from this region is enhanced under a changing climate. These results highlight the need for globally coordinated efforts to tackle air pollution and climate change.
Although nanomaterials are already in widespread use, their risk to the environment is not completely understood. Researchers in the US have developed a next-generation risk-assessment model to better understand nanomaterials’ environmental impact. Applied to the San Francisco Bay area, the model predicted that even soluble nanomaterials could accumulate at toxic levels.

A study of families in Singapore with terminally ill children found that parents tend to defer discussing their psychological pain with their spouses to protect them from emotional distress. The study, conducted by psychologists at NTU through interviews, revealed the parents’ preference to support each other in pragmatic and solution-oriented ways such as discussing treatment options, arranging care plans and sharing caregiving responsibilities....
