Environmental Impact Prediction and Control of Ecotoxicity Based on System Dynamics

Abstract

Eco-toxicant residues permanently stay in the environment and eventually are consumed by plants, animals and humans. Consequently, various diseases and carcinogenic aberrations are caused on humans. Industrial production each year will produce much more eco-toxicants which have been directly discharged into the environment without treatment and ruined the environment in an unpredictable way. The analysis of the mechanism of ecotoxicity unveils the relationship between economic development and the emission load of eco-toxicants. According to the principle of system dynamics, the future emission behavior of eco-toxicants in China was predicted, and the cost required for the eco-toxicant emission control that has surpassed the environment capacity was calculated so as to provide the basis for the development of relevant policy and inputs in the emission control of ecotoxic substances.
