...trouble is that both natural and man-made nutrients (phosphates, nitrate, carbon, iron, calcium) are ending up in bodies of water where they fertilize prodigious growths of algae. As the algae decompose, they use up enormous quantities of oxygen. Fish die; the water looks and tastes so bad that other chemicals have to be added to make even potable water palatable for human use. Finally, a lake turns into a swamp or bog and slowly "dies...
UNTIL the great cyclamate furor bubbled over this fall, few Americans paid much heed to the minute lettering on their cakes and candy bars, diet drinks and instant dinners. Even a magnifying glass was little help in explaining those obscure polysyllables: propylene glycol, calcium silicate, butylated hydroxyanisole, sorbitan monostearate, methylparaben. Today, the portmanteau word for such substances is "additives"-which translates into myriad chemicals that have made even bread a laboratory product and the cheese spread to put on it a test-tube concoction...
...Harvard dining halls are phasing out their use of fruit drinks containing calcium cyclamate-an artificial sweetener which has been suspected of causing cancer in rats...
...trouble with cyclamates (besides the sodium compound, there is a calcium combination for patients on low-salt diets) is that they do not behave predictably in the human body-unlike sugar, which is completely and naturally metabolized. Cyclamates break down in the body, forming chemicals, notably cyclohexylamine (CHA). This, in large doses (upwards of 50 times the probable human dose of cyclamate), is known to cause bladder cancer in rats. Because of the emergence of CHA, cyclamates injected into incubating eggs cause grotesque deformities in many of the chicks and kill others in the shell...
...North Miami; more have been spotted in Hollywood ten miles to the north. Tough, ravenous creatures, whose original home is East Africa, they have chewed up large stretches of grass, stripped the bark off trees, feasted on citrus plants and even devoured paint off buildings-a handy source of calcium for snails' shells...
