Every year, small-scale Kenyan farmers produce thousands of tonnes of mangoes only to watch them rot on orchard floors. Despite its prevalence, the mango industry barely contributes to rural incomes because of the fruit fly problem. Some producers are starting to reduce their reliance on chemicals and develop alternative controls for fruit fly, in the hope of reaching the quality standards required for western export markets. A small Kenyan biopesticide company has developed a pioneering fruit fly control based on a common insect-killing fungus that occurs naturally in the soil. More:

PCBs are industrial chemicals so toxic that were banned 40 years ago. Research has shown that they can cause a range of health concerns, including cancer and neurological problems such as decreased IQ. And yet, because they were commonly used in building materials for decades, they continue to contaminate classrooms in between 13,000 and 26,000 schools nationwide. More:

Under the EU chemicals legislation REACH, all chemicals manufactured or imported above 10 tonnes per year must be assessed for persistent, bioaccumulative and toxic (PBT) properties. For persistence assessment of chemicals a software system was developed combining multiple computational models to predict persistence in several environmental compartments (e.g. water, soil).

Researchers are continuing to discover associations between environmental contaminants and autism spectrum disorder, which now affects 1 in 68 children in the United States. In particular, children born to mothers with higher blood levels of PCBs during the second trimester of pregnancy had roughly an 80 percent higher risk of being diagnosed with autism than children of mothers with the lowest blood levels of the chemicals.

In order to enable sound management of chemicals, with the aim of reducing the risks associated with their use, their effects in the environment should be known and their occurrence should be monitored. However, it is not feasible to do this for the millions of chemicals in use. It is, therefore, important to prioritise the chemicals of highest concern — a major challenge currently facing regulatory bodies. More:

Pesticide exposure can have negative impacts on many species and is a major threat to biodiversity. A new study is one of few to assess the risks specifically for European reptiles. The results suggest that at least one third of European reptile species are at high risk of exposure, with lizards showing the highest sensitivity to pesticides. More:

Drinking water contamination with poly- and perfluoroalkyl substances (PFASs) poses risks to the developmental, immune, metabolic, and endocrine health of consumers. The number of industrial sites that manufacture or use these compounds, the number of military fire training areas, and the number of wastewater treatment plants are all significant predictors of PFAS detection frequencies and concentrations in public water supplies.

Head lice have become immune to most of the over-the-counter chemicals used to treat them, according to a new study. The study, published recently in the Journal of Medical Entomology, found insecticides such as permethrin – one of the most common treatments for head lice – used to be up to 100 per cent effective in killing the parasites when it was introduced in 1984.

How do we determine if a chemical is an endocrine disruptor? With more than 100,000 chemicals on the global market, it is a tremendous challenge to identify those that might cause harm to humans or wildlife. Scientists encourage decision makers around the world to adopt a new chemical evaluation tool that could save lives and money.
