...answer that basic question, the experts discovered that the bullet-marking characteristics of Sirhan's Iver Johnson .22-cal. revolver had changed since the night it was fired in the Ambassador Hotel. The panel found that the inside of the barrel was fouled by a thin layer of copper alloy that probably stemmed from test firings by the Los Angeles police. The panel squeezed off eight shots into a tank of water, compared the bullets with the original three, studied the barrel of Sirhan's gun, and finally gave up. They announced that they could...
CANCER. The U.S. has one of the world's highest incidences of cancers associated with environmental pollution. A recent National Cancer Institute study (TIME, Aug. 11) shows that the industrialized and highly air-polluted Northeast has a particularly high incidence of lung cancer, as do areas where copper and lead smelters are located. The highest rates of bladder and liver cancers are found in counties with plants producing rubber and chemicals, perfumes and cosmetics, soaps and printing ink. One Ohio community, most of whose workers are employed by chemical plants, had a high rate for all three cancers...
Kellogg, Idaho, and El Paso. (Children are metabolically more susceptible to lead poisoning than adults.) Elevated lead levels can also be found in people who live near freeways, where auto exhausts pollute the air. High arsenic levels have been detected in children living near a copper smelter in Ruston, Wash. High levels of lead and other heavy metals, such as arsenic and mercury, are potentially lethal.

A break with Bougainville would cripple the new country; the island is the site of Papua New Guinea's one large industrial enterprise, an immense opencut copper mine that last year generated upwards of $120 million in taxes and royalties-fully half the country's internal revenue...
