In a new study, environmental pollutants found in fish were shown to obstruct the human body’s natural defense system to expel harmful toxins. A protein found in cells of nearly all plants and animals, called P-gp, acts as the cell’s bouncer by binding to the foreign chemical and expelling it from the body. More:

Also known as C8, because of its eight-carbon molecule, PFOA has been found in drinking water in many places across the United States. Although the chemical was developed and long manufactured in the United States, it’s not just an American problem. PFOA has spread throughout the world. More:

Polychlorinated biphenyls (PCBs) were found at elevated levels in children that lived in houses and studied in schools built during this period, before PCBs were more thoroughly regulated in the construction industry. Although food is generally a more concentrated source of these toxins, exposure through these environments should be minimised wherever possible. More: 


Building materials used between 1950 and 1980 in Europe may contribute to PCB air pollution

Chickens foraging on soils containing environmental pollutants can accumulate these chemicals in their tissues and eggs. A 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.  More:

Where do you stand on the role of academia in training the next generation of chemists: should we favour ‘applied chemistry’ or ‘science for the sake of science’? Both sides have valid points; public funding should not be subsidising private industry, but students should receive practical training to help them get jobs after graduation. Navigating the complex issues around toxicity and waste can be a significant impediment to commercial success of any new technology. More:

Research has found evidence for recent contamination of Lake Como, northern Italy, with chemicals banned in the EU since the 1970s. Levels of DDT and PCBs in sediment, aquatic microorganisms and fish were examined. The results suggest glacial meltwater as a source for renewed DDT contamination and show recent contamination of fish above safe levels. The findings demonstrate the need for continued monitoring of persistent organic pollutants in European waters. More:

Since California banned flame retardant polybrominated diphenyl ethers (PBDEs) in 2006, levels of these chemicals in the breast milk of San Francisco Bay area women has fallen by nearly 40%. The US Environmental Protection Agency (EPA) has deemed PBDEs a concern for children’s health, linking them to behavioural problems following postnatal exposure. More:

Alternatives assessment involves comparing the advantages and disadvantages of potential substitutes for toxic chemicals. To determine the factors common to a high-quality alternatives assessment framework, researchers identified 20 frameworks and evaluated six core areas: hazard assessment, exposure characterization, life cycle impacts, technical feasibility assessment, economic feasibility assessment, and decision-making processes for reaching conclusions about alternatives.

Regulatory toxicology has begun to embrace new hazard characterisation approaches which could be integrated into regulatory safety assessments. The vision is to fundamentally change the way we assess the safety of chemicals, by superseding traditional animal experiments with a predictive toxicology that is based on a comprehensive understanding of how chemicals can cause adverse effects in humans.
