Embedded in our furniture and our clothing, our electronics and our food, our carpets and our walls, flame resistant chemicals are everywhere. One type, known as polybrominated diphenyl ethers (PBDEs), have taken a lot of the heat. Not only can they easily leach into the environment, these retardants are commonly inhaled and ingested, where they begin to build up in the body. More:

It was the start of the 2016 growing season when the farmers were told their water was contaminated. Susan Gordon and her husband had run Venetucci Farm for ten years. It was there, against the backdrop of the majestic Rocky Mountains, they had raised their two children. “I was devastated,” says Gordon. More:

Today humans are exposed to thousands of man-made chemicals. Can we infer how cumulative exposures shape our health? I am an environmental toxicologist studying effects of man-made chemicals on our health.

A total of about 400 different agricultural pesticides were used in the United States in 2017, the latest year data is available. More and more pesticides have been used because they “contribute to higher yields and improved product quality by controlling weeds, insects, nematodes, and plant pathogens,” according to the U.S. Department of Agriculture.

Chemicals are essential for the well-being, high living standards and comfort of modern society. They are used in many sectors, including health, energy, mobility and housing. However, most chemicals have hazardous properties which can harm the environment and human health. The European Commission published a chemicals strategy for sustainability on 14 October 2020. More:

The Initiative for Responsible Mining Assurance is one of the newest of more than a dozen mining standards. But most are narrow in focus or lack independence. Some concentrate on single issues like workers’ rights or particular parts of the industry, such as the supply chain. Others were developed by the mining industry without oversight or are just aspirational. There is an appetite for something better.More:

Gov. Gavin Newsom signed legislation Sept. 29 banning these foams in the state, with limited exceptions. The advocacy organization Environmental Working Group estimates that 7.5 million Californians have toxic nonpolymeric PFAS in their drinking water at a level of at least 1 part per trillion, with much of this contamination linked to the use of firefighting foam.

Earlier this year, state and federal researchers reported finding a new, potentially dangerous chemical in soil samples from multiple locations in New Jersey. The compound was a form of PFAS, a group of more than 5,000 chemicals that has raised concerns in recent years because of their potential link to learning delays in children and cancer, as well as their tendency to last in the environment for a long time.

There’s one store where the fields are literally right next to the parking lot. Nineteen year old Maritza Flores and her mom shop at one there all the time. And a lot of the time, when she’s there, she notices this smell. And instantly she knows, someone has just sprayed pesticides. She’s used to it. Maritza Flores has been part of a study her entire life that measures early life exposures to pesticides. More:
