...grebe's problems began in the late '40s when the local mosquito abatement district sprayed thousands of pounds of DDD, a chlorinated hydrocarbon pesticide, on Clear Lake to rid the area of swarms of buzzing black gnats. The chemical, a close cousin of DDT, worked so well that developers previously put off by the gnats began building houses around the lake...

...relatively short time, the liquefied natural gas boils off. If your car sits in the driveway for a few weeks while you're on vacation, you may return to find your fuel has evaporated. Not only is this bothersome and expensive, but I suspect this evaporated hydrocarbon fuel may pollute the atmosphere with unburned hydrocarbons similar to those from evaporating gasoline...

Tests of the device, conducted at the bureau's Bartlesville, Okla., petroleum research center, will continue through July. Thus far, they have demonstrated that the reactor can cut automotive hydrocarbon exhaust to less than 70 parts per million, compared with an average of 900 p. p.m. in exhaust from cars unequipped with pollution-control units. Carbon monoxide has been reduced to less than .7% of the total exhaust from a car equipped with the reactor. Both figures are well within the 1970 standards proposed last week. Nonetheless, said one Du Pont official, the unit is far from commercially feasible...

Fortunately, research scientists on both sides of the Atlantic have just demonstrated two new substances that seem to do well at cleaning up oil-fouled waters. In the U.S., Guardian Chemical Co. of Long Island City, N.Y., has produced a hydrocarbon known as Poly-complex A. When the new substance is sprayed on a slick, it breaks down the oil into tiny particles, combines with them and forms a chemical complex that is readily degraded by bacteria, sunlight and air. "The bacteria have a hard time tackling a big oil slick," says Guardian President Dr. Alfred R. Globus...
