“…This content, however, can be increased up to 4,000 ppm near industrial plants emitting lead, and to more than 300 ppm in urban soils by the combustion of fuels such as wood, coal, and oil. The exhaust fumes of automobiles can increase the lead content by 100 ppm in the soils at the sides of busy roadways up to a distance of about 20 m (54,58,66,69,101,102). A considerable improvement has been achieved through the reduction of gasoline leading being enforced by law.…”

Abstract. The most important sources of heavy metal contamination in their order of significance are air pollution, river sediments, sewage sludges, town waste composts, agricultural chemicals, and industrial waste.Lead accumulation in plants near highways and roads has decreased considerably since the law controlling the lead content of petrol came into force. Hazardous amounts of lead, however, are still concentrated 10-20 m along the sides of highways and roads, and in the strip of up to 5 m there are also higher concentrations of cadmium.
