| Abstract |
A methodology is presented for constructing mass balances for pollutants which move interactively through the air, land and water of an urban-industrial region. Results are reported for lead, zinc, cadmium, and arsenic based on experiments conducted specifically for this study, and on available data from the open literature. The principle on which the analysis is based is the conservation of mass equation for a given chemical element. Using chemical element balance as in flow diagrams for the movement of pollutants through the environment, rates of flow and accumulation can be estimated for the separate environmental compartments. |
