Each day at 4 p.m., the trawlers return, alive with giant bass, mackerel and squirming eels, at the end of a food chain that links family dinner tables to poisons in the sea. Besides mercury, which can damage the brains of fetuses and young children, and can affect healthy adults, there are PCBs, dioxins and flame retardants with unknown long-term effects.

A tipster's recollection of a hazardous substance spill in Los Cerritos Wetlands in the 1950s has led to the discovery of elevated levels of carcinogenic PCBs that could derail a controversial proposal to restore the degraded Long Beach salt marsh, officials say. The Environmental Protection Agency is scheduled to present the results of its study of the contamination to the Long Beach City Council today. "The informant, who wishes to remain anonymous, was an apprentice electrician in his late teens in the early 1950s," said EPA spokesman Robert Wise.
Ethyl Corp., a Richmond, Va.--based chemical company, on Thursday temporarily withdrew its application for approval of a gasoline additive designed to reduce emissions, just days before a deadline for the Environmental Protection Agency to act on it. After meeting with EPA officials Wednesday, the company said it needed more time to answer questions raised about HiTEC 3000, a manganese-based additive that the company contends would reduce emissions while boosting octane in unleaded gasoline.

Sardines that suffocated and died en masse this week in King Harbor have tested positive for a powerful neurotoxin that scientists believeĀ  may have distressed 1 million or more fish off the Los Angeles coastline and caused them to swim chaotically into the Redondo Beach marina. Researchers still believe critically low oxygen levels, not the toxin or an algae bloom, caused the fish to suddenly die Monday night in the Redondo Beach marina. But the discovery of domoic acid in dead fish ?

Scientists investigating why 13 people who ate puffer fish got sick have found a toxin in the species from two Florida rivers. Tests found saxitoxin poison was heaviest in puffers caught in the Indian River near Titusville, the Centers for Disease Control and Prevention in Atlanta said. The CDC said it also was found in Banana River fish.

Government scientists released colorless, harmless gas at four Manhattan locations as part of an effort to find out how fast and far a toxic substance could spread in the city. "It went very well," said Susan Bauer, a spokeswoman for the Urban Dispersion Program, which aims to produce a computerized model of air flow patterns that could help authorities decide how to evacuate people after a chemical or biological attack.

A recent Cornell University report revealed that potatoes could be lethal. Storing potatoes at high temperatures encourages toxins to flourish, putting a whole population of noshers at risk. I prefer peace of mind with my potatoes, so it's good to know that green signals the presence of toxins. No color means the spud is safe, and a healthful source of vitamins A and C, complex carbohydrates, fiber and flavor.

For several years now, seed producers have been using genetic engineering to produce corn and cotton varieties that are toxic to pests. Companies like Monsanto and Novartis have developed so-called transgenic cotton and corn that contain the genes for natural insecticides produced by a bacterium called Bacillus thuringiensis--"Bt" for short. Organic farmers have been using these bacteria for more than 30 years as an alternative to chemical pesticides.

Using federal grant money it might otherwise lose, county officials are creating a "weapons of mass destruction" equipment vehicle to respond to a nuclear, biological or chemical attack. The vehicle will detect radiation and chemical and biological agents, and will be available to anyone who needs it, officials said. The county will use $163,234 to build the unit and to buy a second vehicle to respond to spills of hazardous materials. The county will get $110,000 from federal grants.

A few deft changes have turned a dangerous anthrax toxin into a possible cancer drug, according to a report in the Proceedings of the National Academy of Sciences. Shihui Liu and colleagues at the National Institutes of Health genetically altered one of the three anthrax toxins so that it would be activated by a protein that sits on the surface of virtually all human tumor cells.
