...head upriver, away from the power plants, I ask whether the river, let alone, would repair itself. Not always, they say. The toxic industrial chemicals known as PCBs, which were discharged into the river by General Electric plants until the company agreed to stop, do not biodegrade; they have to be removed. Pollutants have a cumulative effect--what Cronin calls "the death of a thousand cuts." An individual polluter says, "What I alone am doing is not harming this river," which may be so. But Kennedy and Cronin insist the plants that we passed--four in five minutes--are working...
Different pollutants work differently. Some, such as PCBs, are subtle. A female striped bass produces 6 million eggs in a lifetime. If some die from PCBs, it won't be noticed. But humans are also affected when they eat fish contaminated by PCBs; the chemicals can cause cancer and disrupt the functioning of hormones in the body. Other forms of pollution, like nitrate and phosphate runoff from farms, kill the ecosystem by starving fish. These nutrient pollutants are found in fertilizer and in sewage, and they cause excessive growth of aquatic plants when they hit the water. Algae, during their...
...this state would expect her to focus on the issues of concern to New York. They'd want to see her in every county, and they would want to hear her views on health care, education and Social Security reform but also the cost of air fares upstate, PCBs in the Hudson River, the aquifers in Nassau County and on and on. And though she wouldn't have to live in New York, she'd have to run a campaign in New York, which might be tough to do from the White House. Federal election rules are very specific about...
Chronic exposure of animals to polychlorinated biphenyls(PCBs) can lead to disrupted hormone balances, reproductive failures or several forms of cancer...
...often the case with environmental pollution, practices once deemed safe turn out years later to be hazardous. So it was with the PCBs used by General Electric Co. and other manufacturers of transformers. Now cost estimates for cleaning up GE's PCB contamination in the Hudson River alone range as high as $3 billion...
