Heavy metals in the soils and plants of Novosibirsk

摘要

The technogenic contamination of soils and allotment crops in the right-bank regions of Novosibirsk have been studied. An appreciable alkalization of the 0- to 20-cm soil layer resulted from the technogenic impact; abrupt variations in the C_(org) concentration were noted. Ni, Cr, Sr, Zn, Cu, V, Mo, and As were the predominant aoil contaminants. Hazardous amounts of Cd, Pb, and Zn were the most widespread in plants, especially in beet and carrot roots, less frequent in potato tubers and tomatoes were practically free of them.
