Effects of lead speciation in soils on lead levels in food and crops - FS2103

A review of published literature and research reports on soil-plant relationships of lead and the factors affecting these. This will include the concentrations of lead in agricultural and horticultural soils, especially those receiving sewage sludge, levels in food crops, the speciation of the metal in soils and factors affecting the soil-plant transfer coefficient. Crop species and varietal differences will be considered together with the magnitude of atmospheric deposition of the metal onto crop foliage.
To produce a detailed report based mainly on literature published during the last 10 years on the key soil factors affecting the speciation of lead and its uptake and accumulation in the edible portions of food crops. Special attention will be paid to soils amended with sewage sludge in order to determine the key factors, such as sludge metal content, soil pH and organic matter content, which may affect the uptake of lead.
