Ending a bitter fight over diesel exhaust, the California Air Resources Board today is expected to declare diesel soot a cancer-causing pollutant after industry leaders and environmentalists struck a deal that quells nearly a decade of intense opposition. The agreement is an unusual compromise in a war of words that has endured for nine years--the time that state environmental officials have spent reviewing the dangers that trucks, buses and other diesel engines pose to public health.

Workers wearing protective "moon suits" and backed up by volunteer firefighters Friday removed 13,000 bushels of what could be the most toxic grain ever tested from an Iowa farm and trucked it to a hazardous waste dump near here. The delicate $90,000 operation took place more than two months after Iowa officials declared the corn--tainted by a mold-induced carcinogen called aflatoxin--a "hazardous material," the same designation reserved for dangerous chemicals and industrial pollutants.

It was widely reported last week that Swedish researchers had discovered that some highly starchy cooked foods, including potato chips, French fries, biscuits and bread, contained a chemical called acrylamide--a probable cause of human cancer. You have questions? So glad you asked. Question: Oh boy, another food scare. So you're going to tell me not to eat bread or French fries? Answer: No way.

Just when you thought it was safe to go back to the barbecue--bundling your steaks in aluminum foil and keeping fat far from the flames--scientists are surfacing like party poopers with more bad news about grilled meat and cancer. The latest worry is a class of chemicals produced during the cooking of muscle meats like beef, pork, chicken and fish. In laboratory tests and animal studies, the chemicals have been found to damage genetic material and to be carcinogenic.

Quietly last spring, a panel of state-appointed scientists unanimously concluded that one of the world's most widely prescribed anti-cancer drugs, tamoxifen, can itself cause cancer. This finding would normally mean that tamoxifen, which has been prescribed worldwide to about 3 million women with breast cancer, would be added to the governor's list of 404 chemicals "known to the state to cause cancer." But the drug has not been listed. Instead, under pressure from the drug maker and the National Cancer Institute and after personal intervention by the governor, the Wilson Administration has delayed a decision indefinitely.

Atty. Gen. John K. Van de Kamp on Wednesday sued four medical and food sterilization firms in Los Angeles and Orange counties, saying they have exposed an estimated 3 million people to emissions of toxic ethylene oxide, a potent carcinogen that also can cause reproductive abnormalities. In the most sweeping lawsuits ever filed under Proposition 65, the 1986 anti-toxics measure, Van de Kamp charged that the companies failed to adequately warn the public of possible exposure to the toxic gas.

Smoking a joint is equivalent to 20 cigarettes in terms of lung cancer risk, New Zealand scientists have found, as they warned of an "epidemic" of lung cancers linked to cannabis. In a report in the European Respiratory Journal, the scientists said that cannabis could be expected to harm the airways more than tobacco because its smoke contains twice the level of carcinogens, such as polyaromatic hydrocarbons. The method of smoking also increases the risk, since joints are typically smoked without a filter and almost to the very tip, which increases the amount of smoke inhaled.

Re "Traces of Prescription Drugs Found in Southland Aquifers," Jan. 30 Prescription drugs in reclaimed water -- that's no surprise. The National Research Council, in a 1998 study, indicated that reclaimed water is unsafe for drinking because the technology does not exist to test for thousands of potential toxins and carcinogens that can survive the reclamation process. Instead of waiting for the other shoe to drop, water districts should be considering technologies, such as desalination, that are now less expensive and produce safer water.

The styrene folks are not amused — not amused at all — by the federal government’s addition of the compound to a list of substances that might cause cancer. Representatives from — the Styrene Information and Research Center -- said they would fight "vigorously" to remove styrene’s new designation as “reasonably anticipated to be a human carcinogen.” That designation appears on the U.S. Department of Health and Human Services’ most recent Report on Carcinogens. The industry group contends that the inclusion is “completely unjustified.” In a news release Friday, the group condemned the inclusion, using terms such as “flawed process” and “preponderance of data” and tartly pointing out that the latest research by European scientists doesn’t support a link between styrene and cancer.
