Fate of Trace-Metals (Impurities) in Subsoils as Related to the Quality of Ground Water.

摘要

The report presents findings of a two-year study of the ground water pollution hazard from trace-metals which are applied in agricultural chemicals. The study establishes whether movement through the soil constitutes a significant source of trace-metals found in surface and ground water,identifies the properties of soils that control the extent of (quantity of) metals moving in and through the soil,establishes the relation of this movement to the concentration of the various metals in the water originating on agricultural lands,and examines the possible use of cationic polymers or other organic compounds in controlling the extent of trace-metals in water.
