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.

Fluorinated compounds are everywhere. A bouquet of poly- and perfluoroalkyl substances (PFASs), prized for their ability to repel both water and oils, have been used in diverse applications from non-stick frying pans to firefighting foams for decades. Yet they resist degradation, making them almost ubiquitous in the environment; and they tend to bioaccumulate in living creatures, raising health worries. More:

Fish show high concentrations but since microplastics are mostly present in the stomach and intestines they are usually removed and consumers are not exposed to them. But in crustaceans and bivalve molluscs like oysters and mussels, you eat the digestive tract so there is some exposure there. Trophic transfer of POPs within the marine food webs has been reported to be associated with oceanic plastics and biomagnification of POPs has been found. More:

During tosca’s 40-year run only a little over 200 chemicals have been assessed out of roughly 85,000 chemical substances in its inventory. Currently, a new chemical has to be shown to pose an ‘unreasonable risk’ before more information can be requested. Making a call on the risk a chemical poses is difficult to do without more information, however. More:

Agent Orange – named after the orange stripes on the barrels used to transport it – was used extensively by the US military to remove forest cover and destroy militia crops from 1962 to 1971 during the war. The mixture used was contaminated with a highly toxic dioxin called 2,3,7,8-tetrachlorodibenzodioxin (TCDD), formed as an unintended by-product during the 2,4,5-T manufacturing process when temperatures were too high.
