Botha showed no signs last week that he was ready to make concessions. In fact, he seemed particularly pugnacious as he told a political meeting that if sanctions against South Africa resulted in a cutoff of chromium exports, it would put 1 million Americans out of work and bring Western Europe's auto industry to a standstill. South Africa supplies more than 80% of the U.S. and Europe's chromium, which is used in the manufacture of stainless steel. A spokesman later said Botha's statement was not a threat; he was only pointing out that sanctions can boomerang...
There's more to tattooing than pinpricks. The first detailed analysis of tattoo inks, presented at the American Chemical Society meeting last week, found copper, iron, lead, lithium, chromium and strontium. Rub-ons, anyone...
...into industry lobbies and weakened previously-set regulatory policies. In a document released by the government late last year, the EPA decided to revise its December 2000 findings (in which it placed mercury under the most stringent regulations of the Clean Air Act alongside other neurotoxins such as asbestos, chromium and lead) to place mercury under a significantly less stringent provision of the Act which deals with pollutants less toxic to humans, such as smog...
...what are the facts? There is no doubt that PG&E irresponsibly dumped chromium-6, and that the substance is a carcinogen. When inhaled regularly over long periods of time, it can cause cancer of the lung and the septum. But current studies show that, ingested in the trace amount found in Hinkley's water, or in food, it's harmless. According to a 1998 Environmental Protection Agency report on chromium-6, "No data were located in the available literature that suggested that it is carcinogenic by the oral route of exposure...
...Schwarcz, director of McGill University's Office for Chemistry and Society, explains why. The difference, he says, "is that ingested chromium-6 encounters hydrochloric acid in the stomach's gastric juices, and is converted to chromium-3, which is innocuous." Anyway, he points out, "no single toxin causes the wide array of conditions that afflict Hinkley residents...
