Effects on the Lithosphere


Pollution

Pollutants are often dispersed across cities or concentrated in industrial areas or waste sites. Lead- based paint used on roads and highways and on buildings is one such example of a widely dispersed pollutant that found its way into soil. But humans also bury tremendous amounts of waste in the ground at municipal and industrial dumps. These materials can severely contaminate soils. Even such commonplace items like gasoline storage tanks at filling stations have the potential to cause serious contamination. When this problem was discovered a decade ago, hundreds of storage tanks had to be removed and replaced with safer containers. The most extreme cases of industrial pollution, as at Love Canal in Buffalo, New York, have forced the abandonment.
