The state of North Carolina formally warned Chemours that in 60 days, it will prohibit the plant from emitting to the atmosphere hexafluoropropylene oxide dimer acid (HFPO-DA) and two related fluoroethers that hydrolyze into HFPO-DA. One of those chemicals is GenX, a surfactant used as a polymerization aid to manufacture fluoropolymers. Fluoropolymers are used as membranes in fuel cells and to produce chlorine and sodium hydroxide. More:

The levels of harmful flame retardants in children's blood are dropping every year, according to a new study of kids from New York City. The flame retardants—polybrominated diphenyl ethers (PBDEs)— were used for decades in furniture, electronics and clothing in an effort to slow the spread of flames if they catch fire. The chemicals were voluntarily phased out starting in 2004 because they build up in the environment and people—PBDEs are found in the air (in and outside our homes), some food, and in people all around the world.


Good News: Toxic flame retardants declining in NYC kids’ blood

A byproduct of yellow pigment manufacturing is showing up in Great Lakes air—and it isn't going away Toxic PCBs are on a steady decrease in Great Lakes region air but over the past decade one type remains constant—it's likely due to yellow pigment manufacturing. More:

When Donald Taves discovered two kinds of fluoride in his blood in the late 1960s, he immediately knew something was wrong. Everyone assumed that blood contained just one type of fluoride, a naturally occurring form that health officials added to drinking water to prevent cavities. But levels in people’s blood didn’t seem to relate to those found in their water supply. More:

Le Muséum national d’histoire naturelle (MNHN) et le Centre national de la recherche scientifique (CNRS) annoncent les résultats principaux de deux réseaux de suivi des oiseaux sur le territoire français et évoquent un phénomène de « disparition massive », « proche de la catastrophe écologique ». « Les oiseaux des campagnes françaises disparaissent à une vitesse vertigineuse, précisent les deux institutions dans un communiqué commun. En moyenne, leurs populations se sont réduites d’un tiers en quinze ans. » More:

Luring falcons to farms can keep pesky insects, rodents and other critters in check—putting a dent in poison and pesticide use. Summer carloads of sweet-toothed tourists, flush with cash and seeking local pies and jams, are an economic godsend in the cherry-growing region. Other hungry visitors are less welcome—voles, weevils, fruit flies, grasshoppers and pest birds do significant damage to local crops. More:

Glaciers, like many venerable objects, can act as time capsules. Like a dusty vinyl record holds an era’s songs, ice holds very old molecules—not just the H2O of snow, but traces of airborne particles like dust, ash, and chemicals that hitched a ride on falling flakes. In the Antarctic, Adélie penguins harbor consistent levels of the pesticide DDT. More:

Pesticides accumulate in bodies with high fat content. This conclusion has been reported by scientists who have been studying seabirds and marine mammals of the Sea of Okhotsk and the Bering Sea for several years. In a scientific article, the authors presented the results of a study of organochlorine pesticide (OCP) build-up in the bodies of seabirds and marine mammals living in the north-western part of the Pacific Ocean.

Chemicals known as perfluoroalkyl substances (PFAS)—used frequently in fast-food wrappers and other products for their oil- and water-repellant properties—have been linked to hormone disruption, immune dysfunction, high cholesterol and even cancer. Now, a new study suggests that exposure to the chemicals could make it harder to keep weight off after dieting. More:

In regions of the world threatened by malaria, bed nets treated with insecticides are an increasingly common public health tool to fend off mosquitos. But there is growing evidence that the nets, often provided for free or at a subsidized price by hospitals and aid organizations, are being put to other uses, including fishing. More:

Long strips of bright wildflowers are being planted through crop fields to boost the natural predators of pests and potentially cut pesticide spraying. Concern over the environmental damage caused by pesticides has grown rapidly in recent years. Using wildflower margins to support insects including hoverflies, parasitic wasps and ground beetles has been shown to slash pest numbers in crops and even increase yields.
