RESUMEN
The use of lead in petrol in Israel is described. Results of a soil survey are presented and the distribution of lead in soil, water, air, edible plants and the human organism is reviewed. Soils do not generally show high lead retention. The concentrations of lead in water, air and edible plants are low as is the concentration of lead in blood. A possible source of danger is the use of spent motor oil as a fuel in glass making furnaces.

Fruit, vegetables and other crops grown in areas of heavy traffic were sampled and analysed for lead. The maximum lead content in washed vegetables was found in lettuce which contained about 0.5 mg/Kg (fresh weight). The low lead contents of the crops are partially due to the low lead contents of the soils on which they are grown. These in turn are a reflection of the lack of organic matter and clays in the soils. There appears to be no undue danger to health from eating crops tested.
