大气污染:关键词:sulfur dioxide(二氧化硫,一氧化碳)
Although substantial progress had been made, sulfur dioxide and monoxide levels were up 25 percent nationally and particulates were increased by more than 14 percent.

Of 20,000 major stationary sources of air pollution, about 5,000 failed to meet the schedules, and well over half the steel plants and nonferrous smelters in the United States continued to be in violation of federal regulations.
核污染(Chernobyl: 切尔诺贝利核事故)
On April 26, 1986, another serious incident alarmed the world. One of four nuclear reactors at Chernobyl', about 130 km (about 80 mi) north of Kyiv (now in Ukraine) in the USSR, exploded and burned. Radioactive material spread over Scandinavia and northern Europe, as discovered by Swedish observers on April 28. According to the official report issued in August, the accident was caused by unauthorized testing of the reactor by its operators. Radiation about 50 times higher than that at Three Mile Island exposed people nearest the reactor, and a cloud of radioactive fallout spread westward. Unlike most reactors in western countries, including the United States, the reactor at Chernobyl' did not have a containment building. Such a structure could have prevented material from leaving the reactor site.
