Soil and grass were sampled in industrial, municipal and rural regions at a distance of up to 10 m from the edge of roads. Lead, cadmium and zinc concentration was determined. The highest lead concentration in the soil was found in samples collected 5 m from the edge of the road, at 17.0-334.7 mg kg . The largest impact of exhaust emission from the vehicles on the roads on vegetation and soil pollution was found 2 m from the edge of the road. This phenomenon appeared in all regions regardless of the level of industrialization. Lead concentration in the analysed grass varied in the range of 7.3 - 26.4 mg kg"1 of dry matter. The maximum concentration exceeded twice the EC pasture plants standard - 10.0 mg kg" . To assess animals’ exposure to lead a quantity of this metal was introduced into sheep with grass grown in the vicinity of the roads. In a heavily polluted area the amount of lead absorbed with grass and soil could reach 10.26 mg daily. In the case of the largest absorption, which occurs especially in industrial regions, lead concentration in the livers and kidneys of sheep was estimated at 0.013 and 6.0 fig g". Human lead intake with 200 g of kidney consumption was calculated at 1200 /(g and exceeded the ADI 3 times.
