...massive poisoning, made no headway against the frogs. The only chance left, says James St. Amant, supervisor of the state department of fish and game, is to find "a critter that'll feed on them." That may be difficult since the frog's skin apparently contains a toxic venom and tastes awful. Even an alligator passed up a dish of clawed frogs-legs...
...alternatives to nuclear power, which depend on existing technology, will avoid the necessity of storing wastes that remain toxic for 500,000 years, he added...
...blood cells that occurs after they unload their cargo of oxygen. But how? During cocktail-party chatter, Lab Director Cerami learned from a colleague that a byproduct of urea-a chemical called cyanate-can prevent sickling. Tests on both animals and humans confirmed this, but the cyanate also had toxic side effects on the nervous system. So the Rockefeller scientists suggested adding the cyanate directly to the blood. That idea has led to the experimental development elsewhere of machines, somewhat like artificial kidney units, which allow the cyanate to react with the blood outside the body...
...kidneys remove toxic substances from the blood. The drinking of urine will result in reabsorption of these substances. A healthy adult could probably consume a small daily portion of his urine without complication. However, consumption of even a small amount of urine by a person with marginally functional kidneys could lead to uremic poisoning by progressively elevating the blood concentrations of toxic substances. Readers who are willing to "drink up" should know the odds before they toast their health...
...that have been tested in one microbial system, 90 per cent of those that scored positive for mutagenicity were also found to induce tumors when studied in animals. In light of this high correlation between mutagenicity and carcinogenicity, test systems for mutagenicity are being used increasingly to identify potentially toxic substances early in product development. Recent reports do indicate that saccharin-containing products produce mutations in test systems...
