碩士 === 國立高雄第一科技大學 === 環境與安全衛生工程所 === 92 === Abstract
This study aims to evaluate the contamination of heavy metals (As, Cd, Cr, Cu, Pb, Hg, Ni, and Zn) in the soil of Kaoshiung metropolitan area and to estimate the human health risk following exposures. Kaohsiung, an industrialized city, is composed of downtown, rural, farming and industrial areas. The data of eight heavy metals in soil, which were collected form the soil inspections conducted by Environmental Protection Bureau of Kaohsiung Municipal City Government from 1997 to 2003, were analyzed in this study. The studying areas include parks, schools, greensward and farmland in twelve districts of Kaohsiung. The results of the soil analysis show that the heavy metals concentrations were lower than the Soil Pollution Monitoring Standards of Taiwan. The Exposure and Risk Assessment Decision Support System (DSS) developed by American Petroleum Institute (API) was used to estimate human health risk following soil exposure to eight heavy metals. The analyzed routes of exposure included ingestion, dermal contact and inhalation of soil. The results show that the lifetime cancer risks for all exposure scenarios were less than the accepted level of 1×10-6,and the hazard Index for non-carcinogenic effects were all less than one. This study also estimated the health risk based on the Soil Pollution Monitoring Standards and Soil Pollution Control Standards of Taiwan. The results show that lifetime cancer risk could be higher than 1×10-6 if all eight heavy metals levels higher than the Soil Pollution Monitoring Standards with 5 to 10 years of exposures.
