...waters each year. For all its natural beauty, however, the Chesapeake is also threatened by man. Wastes poured into the upper reaches of the Susquehanna have begun to pollute the river. Continuing discharges into the river will flow into the bay, disrupting its ecological balance and leaving it as toxic as the estuaries adjacent to Manhattan...
...TOXIC MATERIALS are a growing worry, particularly lead and mercury. The amount of mercury in fish is expected to rise because more microorganisms are being produced by the increased amounts of nutrients, mainly from industry and agriculture, in U.S. waters. The microorganisms move up the food chain into fish, and man eats the fish. Heavy doses of mercury can result in nervous-system damage, even death. Lead, long a factor in urban air pollution, has now been found in the oceans. The upper layers of the oceans seem to be polluted with industrial lead, says the report, and "atmospheric levels...
...people's department." But has it turned out that way? Ralph Nader thinks not. In a 491-page report by one of his indefatigable groups of "Raiders," Nader charges that the department favors big "agribusiness" and fails to protect otherwise defenseless Americans from bad meat, contaminated poultry and toxic pesticides...
...combat the new onslaught, the pesticide industry offered up a chemical poison trademarked Sevin. It is not as toxic or long-lived as DDT, but just as surely kills the caterpillars. Nonetheless, environmentalists strongly oppose Sevin because it is fatal to fresh-water insects, fingerling fish and bees. Heeding the environmentalists' warnings, residents of most infested areas this year voted against aerial spraying of pesticides and settled back to let nature take its course...
Doctors now replace lost or damaged vitreous with either natural material taken from donors, saline solutions, air, silicone or other synthetics. None of those materials is completely satisfactory. The synthetics sometimes trigger toxic reactions that lead to further eye damage, the air is soon absorbed, and transplanted human vitreous may provide only short-term benefits. Now a research team at Cornell University Medical College's Rogosin Laboratories has developed a material that overcomes all these problems. According to Dr. Michael W. Dunn, he and his colleagues are using collagen, a natural body substance, to replace lost or damaged vitreous...
