Why a new treaty? The world produces 400 million tonnes of plastic every year. Less than 10 per cent is being recycled and the rest ends up incinerated, dumped in a landfill or in the ocean and other ecosystems. With plastic production expected to double in the next 20 years, plastic pollution is also set to worsen. More:

Chemists and chemical engineers could certainly do more to align their molecular machinery with sustainable development. An obvious place to begin is in the classroom by transforming the way chemistry is taught. An international network of motivated teachers and educators are looking to do just that through promoting a concept deemed green and sustainable chemistry education. More:

Once called “the world’s parliament on the environment,” the UN Environment Assembly (UNEA) has a unique role in global environmental governance. UNEA is an initiator or catalyst. It identifies emerging issues and (hopefully) agrees to the next steps for learning about and addressing these issues. More:

PFAS, or per- and polyfluoroalkyl substances, are a family of man-made chemicals used for their water- and stain-resistant qualities in products like clothing and carpet, nonstick cookware, packaging and firefighting foam. The family includes 5,000 compounds, which are persistent, remaining both in the environment and human body over time. More:

We’ve reached a tipping point – there are too many toxic chemicals in circulation for the world to handle! That’s the main conclusion from a recent study by some of the world’s foremost chemical scientists. Interview with one of the authors, Professor Bethanie Carney Almroth, to talk about the study and what we can do to turn this situation around. More:

The U.S. Geological Survey has detected the toxic “forever chemicals” known as PFAS in public and private drinking water wells in 16 Eastern states. PFAS were detected in public and private drinking water wells in Alabama, Florida, Georgia, Illinois, Indiana, Kentucky, Massachusetts, Maine, Mississippi, New Hampshire, Ohio, Pennsylvania, Rhode Island, South Carolina, Tennessee and West Virginia.

Everyday levels of a pregnant woman’s exposure to mixtures of endocrine-disrupting chemicals like bisphenol A (BPA), phthalates, and per- and polyfluoroalkyl substances (PFAS), put their child at an increased risk of delayed language development, according to new research. More:

Whether it’s lead, phthalates, per- and polyfluoroalkyl substances (PFAS), or BPA, nearly every time scientists assess chemicals, they lower the thresholds for safety. Doses that were previously thought innocuous, we find, turn out harmful. Why does that happen? More:

A new study found that in a marine environment, microplastics absorb and concentrate toxic organic substances and thus increase their toxicity by a factor of 10, which may lead to a severe impact on human health. More:

In Europe, scientists have blown the whistle on farmworkers' exposure to pesticides for years. Farm workers are not protected from pesticides. Their exposure has been linked to serious illnesses, including Parkinson’s disease and blood cancers. Recommended equipment, expensive, untested and rarely worn as it is, does not provide effective protection. Without this presumed protection, dangerous pesticides would be banned. More:

As regulators and growing public awareness have put the screws on some of the more well-known PFAS chemicals, other variants are marketed as safe and are rarely scrutinised.
