This study investigated the human health risks of trichloroethylene from Industrial Complex A. The excessive carcinogenic risks for central tendency exposure were $1.40{ imes}10^{-5}$ for male and female residents in the vicinity of Industrial Complex A. The excessive cancers risk for reasonable maximum exposure were $2.88{ imes}10^{-5}$ and $1.97{ imes}10^{-5}$ for males and females, respectively. These values indicate that there are potential cancer risks for exposure to these concentrations. The hazard index for central tendency exposure to trichloroethylene was 1.71 for male and female residents. The hazard indexes for reasonable maximum exposure were 3.27 and 2.41 for males and females, respectively. These values were over one, which is equivalent to the threshold value. This result showed that adverse cancer and non-cancer health effects may occur and that some risk management of trichloroethylene from Industrial Complex A was needed.
