PCBs were domestically manufactured for construction materials in the United States beginning in about 1930 until 1979, a time period that coincides with a boom in school construction to meet the ...

HOLDERNESS, N.H. (AP) — Navigating her boat toward a wooden platform floating in an idyllic New Hampshire lake where “On Golden Pond" was filmed, biologist Tiffany Grade spotted what she had feared.

Nearly a half century after the U.S. banned PCBs, communities around the Great Lakes are still digging the toxic chemical out of waterways.

Polychlorinated biphenyls, or PCBs, are stable man-made organic compounds. That was their value to industry and in the past few decades that has been the problem. They were used from the 1920s as ...

PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites -- the filament-like projections that conduct electrochemical signals between neurons ...

People who have been exposed to both PFAS and PCBs are more likely to be diagnosed with multiple sclerosis (MS). These new research findings are based on analyses of blood samples from more than 1,800 ...

PCBs emerge in the world of construction as an attractive and efficient tool for ensuring that caulking and other processes are long-lasting. These chemicals were particularly appealing for builders ...

In three new studies researchers provide compelling evidence of how low levels of polychlorinated biphenyls (PCBs) alter the way brain cells develop. Researchers explain the relationship between PCB ...

A trio of researchers at Chemistry Matters Inc., in Canada, has found evidence suggesting that more polychlorinated biphenyls (PCBs) are being generated today than before they were banned. In their ...

Nearly a half century after the U.S. banned polychlorinated biphenyls, also known as PCBs, communities around the Great Lakes are still digging the toxic chemical out of rivers, harbors and lakes.
