Abstract
Human health risk assessment can connect the contaminated environment media with the scenario of human life and estimate the probability of adverse health effect in humans. Recently, this approach has been largely applied in several areas and helps assessors or leaders make the decision. The research is focus on the typical air toxic pollutant – dioxin from the sinter process of the steel plant in Linhi industrial park in Kaohsiung city . I combine the exposure scenario with contaminated environment media which was predicted by the air dispersion model and multiple media model in order to understand whether the emission standard of the dioxin from steel plant is reasonable for the local residents. Furthermore, I also evaluate the human health risk in the real pollutant emission status. The results show the both risk are below 10-6 The research also discuss and investigate the system from multiple source of dioxin ,including sinter process of the steel plant and background concentration by the accumulative health risk analysis . The results show the human health risk from background concentration can’t be ignored.
