People living along France's Rhone River and people who regularly eat fish from the river have tested positive for a toxic chemical, health officials said. Some of those tested had four to five times the so-called safe level of PCB, or polychlorobiphenyl, in their blood, EuroNews.net reported Friday. PCB is known to be toxic, said Pierre Souvet, president of the medical association in Provence, which carried out the tests on 52 Rhone residents. It can cause cancer, neurological problems...

By Cushing, C A Golden, R; Lowney, Y W; Holm, S E ABSTRACT Alkaline copper quaternary (ACQ) Type D is one of several compounds currently being used as a chemical preservative to treat wood for prevention of rot and decay. As wood weathers naturally, human exposure to ACQ might occur through dermal contact or incidental ingestion of residues from the wood surface. To understand any potential for health risks from the use of ACQ- treated wood, a health-based evaluation was undertaken on the...

By REX SPRINGSTON They give their lives so that ours will be safer. Of course, when you're a fathead minnow or a water flea, you don't have a lot of choice.

WASHINGTON (AP) - After more than seven years of study scientists have isolated a toxin that they say may have killed millions of fish along the East Coast in the 1990s. The fish kills were associated with a parasitic algae called Pfiesteria, but until now researchers have been unable to determine how the organism killed the fish. Peter Moeller, a chemist with the National Oceanic and Atmospheric Administration, said Thursday that he was able to isolate a toxin from Pfiesteria, but that the...

Durham, N.C.  - Duke University Medical Center researchers have found that the naturally occurring marine toxin domoic acid can cause subtle but lasting cognitive damage in rats exposed to the chemical before birth. Humans can become poisoned by the potentially lethal, algal toxin after eating contaminated shellfish. The researchers saw behavioral effects of the toxin in animals after prenatal exposure to domoic acid levels below those generally deemed safe for adults, said Edward...
