Risk Assessment of Classic Endocrine Disrupting Chemicals in Beijing-Tianjin-Tangshan District

This terms Endocrine Disrupting Chemicals (EDCs) are also called Environmental Estrogens. The synthetic chemicals in the artifice products may affect the endocrine system, associated with developmental, reproductive and other health problems in wildlife and laboratory animals. In the Beijing-Tianjin-Tangshan district, there are 38.58 million populations. And chemical engineering of petroleum and coal are the main industries. So, the extent of exposure and safety of health are very important for residents in this area. But, there are no enough attentions to focus on the environmental risk and disruption of EDCs. And, Many are chemicals produced for specific purposes and are used in pesticides, plastics, cosmetics, electrical transformers and other products. Then, how to assess so many compounds and determine the risk rank of potential effects on physiological functions? The Priority detected EDCs have been chosen form the many industrial compounds by the system of fuzzy clustering analysis. In this paper, analytic hierarchy process (AHP) has been introduced to accumulate the weight value of the properties parameters for the risk assessment system.
