...blood increases. The non-smoker might even face a greater danger from cigarettes than the smoker. The cigarette filter often protects the smoker; the non-smoker has no such protection and must breathe the smoke that wafts his way from the cigarette's end. That unfiltered smoke contains more cadmium than is contained in filtered smoke. (Cadmium, in large doses, is connected with emphysema, chronic bronchitis, and hypertension). Unfiltered smoke also contains almost twice the tar and nicotine of filtered smoke. A study in Germany revealed that a non-smoker in a closed room where several cigarettes have recently been...
...star of Texasgulf's metals division is the Kidd Creek Mine at Timmins, Ont., the world's richest source of zinc and silver as well as a major supplier of copper, lead and cadmium. In addition to its Canadian holdings, Texasgulf owns sulfur mines in Texas and Louisiana, a potash mine in Utah, three iron mines in Australia and woodlands in Pennsylvania. Despite a somewhat desultory performance in the stock market in recent years, Texasgulf has impressive profits. In this year's first half, it earned $22.9 million, almost double last year's rate, on sales...
...essential ingredients for the great cleanup are all there. Every sort of pollutant, from heavy metals like mercury and cadmium to heated water from electricity plants, is defined and limited. The bill provides up to $18 billion for municipalities to build new sewage-treatment plants, with 75% of the money being paid by Washington and 25% by states and cities. It would finance the removal of toxic sludge from river and lake bottoms and also provide low-interest loans to small businesses for antipollution equipment...
...energy for their size and weight. Enough of them to power an electric car would weigh as much as an entire conventional automobile. Furthermore, there is little room for improvement; lead-acid batteries have already been developed close to their theoretical peak. Other batteries using different materials-nickel and cadmium, zinc and silver, or sodium and sulfur-have greater energy density, but they have not yet proved practical either, largely because of high costs...
...humans. First came the so-called Minamata Disease, caused by a fertilizer plant dumping methyl mercury into a bay near the town of Minamata; it produced in its victims an appalling array of eye and brain damages. Another painful new disease called itai-itai (literally, ouch-ouch) derived from cadmium flowing into the Jintsu River from a mining and smelting factory. Its symptoms: a softening and finally a breaking of the bones. Then, two years ago, a wave of smog-associated complaints began afflicting Tokyo residents. So far, at least 30,000 victims have been reported in the capital...
