I am an environmental toxicologist studying how man-made chemicals affect our health. I was always interested in understanding how our current health is shaped by chemical exposures during the embryonic and early postnatal period – life stages that are particularly sensitive to environmental stressors.

The hefty price tag reflects the state’s serious PFAS problem. New Jersey is thought to be one of the states most contaminated with these chemicals. Seventy percent of drinking water samples taken from 20 of New Jersey’s 21 counties contained at least one compound from the class of chemicals, according to research done in 2009 and 2010. And, last year, another state study showed that all surface water samples taken from 11 waterways and ecosystems around New Jersey contained PFAS. All the fish found there contained the chemicals as well. The state is also home to military bases that have been contaminated by firefighting foam, as well as several industrially polluted sites.

At the Sweeney Water Treatment Plant in North Carolina, engineers are finalizing designs for a new system aimed at removing a mix of persistent industrial chemicals from their drinking water. These molecules are troublemakers—wily foes that have evaded capture by traditional water treatment methods. They’re known collectively as PFAS, the family of nonpolymer per- and polyfluoroalkyl substances nicknamed “forever chemicals.” More:

Every year US farmers use about a billion pounds of chemicals on crops, including the fruits, nuts, and vegetables many parents beg their kids to eat. The Department of Agriculture and the Food and Drug Administration are charged with ensuring that these chemicals don’t endanger consumers, and both agencies test the food supply for pesticide residues each year. They focus on foods eaten by babies and children, whose developing bodies are particularly sensitive to toxic chemicals, and typically report that pesticide residues in these products rarely exceed safety standards.

Thousands of seals died along the coasts of the heavily polluted Baltic Sea in the late 1980s. Scientists traced the deaths to a virus similar to the one that causes distemper in dogs. Last year, the same virus struck hundreds of seals in Maine. In both instances, researchers believe that persistent organic pollutants, such as polychlorinated biphenyls (PCBs), dioxins, and furans, played an indirect role in the seals’ demise. More:

En Vietnam, el ejército de EE UU mantuvo dos guerras: una contra el Viet Cong y otra contra la naturaleza. En esta, los militares estadounidenses usaron millones de litros de herbicidas contra la selva donde se escondían los comunistas y los cultivos de arroz que les alimentaban. El herbicida más usado fue el agente naranja. Una revisión de diversos estudios muestra que, 50 años después de que dejaran de rociarlo, aún hay restos altamente tóxicos de este defoliante en suelos y sedimentos, desde los que entran en la cadena alimenticia.

Now, as environmental concerns about these fluorinated chemicals mount, Dutch and US environmental regulators are taking a close look at Chemours’s practice of shipping reclaimed HFPO-DA from its plant in the city of Dordrecht, the Netherlands, to one in Fayetteville, North Carolina. In addition, Dutch authorities are raising concerns about the environmental release of HFPO-containing material as it is hauled for reprocessing or disposal. More:

Per- and polyfluoroalkyl substances (PFAS) are the largest identified complex group of environmental pollutants reported in the scientific literature. These chemicals have many uses in the marketplace. However, their strong carbon–fluorine bonds keep them from degrading, and they bind to blood proteins, hindering their elimination from the body.

That was 2016. Since then, the Defense Department has admitted that it allowed a firefighting foam to slip into at least 55 drinking water systems at military bases around the globe, sometimes for generations. This exposed tens of thousands of Americans, possibly many more, to per-and polyfluoroalkyl substances, a group of man-made chemicals known as PFAS that have been linked to cancers, immune suppression and other serious health problems.
