A pesticide known as "DDT's cousin" is still being used in the United States, despite evidence of its toxic effects. The EPA acknowledged that even though it had not fully addressed all of the ecological and human health risk concerns regarding endosulfan, it had taken a number of mitigation measures to make its use safer.

Every day thousands of people make decisions that affect the chemical market. Most decisions are about the costs, availability, and performance of products; few involve consideration of human health or the environment. If the consumer market offers an important opportunity for promoting safer chemical production and consumption systems, the amount of chemical information in the market must expand, and the number of products that take health and environment into account must increase.

Chemistry is having “an innovation crisis”, according to John Warner, co-author of the 12 Principles of Green Chemistry. “We need to ask if the way we’re training future scientists is fitting the need of society.” “Instead of enacting another law that bans or regulates a chemical or a molecule that has a toxic or environmentally destructive effect, we need to think about how we invent a product that doesn’t have that effect”, he said.

Until recently few people had heard much about chemicals like C8. One of tens of thousands of unregulated industrial chemicals, perfluorooctanoic acid, or PFOA — also called C8 because of the eight-carbon chain that makes up its chemical backbone — had gone unnoticed for most of its eight or so decades on earth. PFOA was slippery, chemically stable, and a critical ingredient in the manufacture of hundreds of products, including Teflon. More:

When parents are exposed to chemicals, they can influence epigenetics, or the cues that turn genes on and off. These patterns can later influence how genes are passed on to offspring. More:
