Cordless and snout-shaped, the Dustbuster is 14 1/4 in. long and weighs 1.4 lbs. To clean up small domestic disasters, the user grabs the Dustbuster from its wall rack, vacuums up the mess and returns the machine to its base. There, its three nickel-cadmium batteries are recharged so that it will be ready for the next spill. Life expectancy: 150 hours, or five years of 15-to-20-second bursts...
...growth of the bay area's population has been accompanied by the peril of pollution. The EPA found high concentrations of such heavy metals as copper, cadmium and lead in rivers flowing into the bay from Baltimore, Washington and other cities; high levels of organic compounds, including PCB's, Kepone and DDT, were detected in Pennsylvania and Virginia rivers that flow into...
...more rain, which washes chemicals onto the trees. "Most people think of remote mountains as ideal vacation spots that are very clean, but they're not," declares Johnson. Many isolated areas in the mountains of New England have abnormally high levels of copper, zinc, nickel and cadmium. And the Green Mountains of New Hampshire, seemingly pristine, in fact rival big cities when it comes to lead pollution...
...designed to glide without power for a distance at least 16 times its altitude. In the case of Air Canada Flight 143, that meant more than 100 miles. As soon as the second engine went out, an elaborate series of automatic backup mechanisms was activated. A 24-volt nickel-cadmium emergency battery took over the plane's dead electrical system, providing enough juice to operate the radio and the key instruments in the cockpit. At the same time, a ram-air turbine dropped into position beneath the aircraft's belly. The airstream passing through the turbine generated enough...
...most experts believe that the current problem is directly traceable to the burning of fossil fuels by power plants, factories and smelting operations and, to a lesser extent, auto emissions. When tall smokestacks vent their fumes, sulfur dioxide, nitrogen oxides and traces of such toxic metals as mercury and cadmium mix with water vapor in the atmosphere. Chemical reactions follow that form dilute solutions of nitric and sulfuric acids-acid rain...
