Abstract：Air samples were collected to determine the concentrations of the 16 polycyclic aromatic hydrocarbons (PAHs) in some high lung cancer rate area of our country. Total 24 h food and drinking water of the subjects were collected. Daily total exposure to Bap of local people was analyzed through the approaches of air and food. Concentrations of 14 trace elements were determined using ICP-MS and daily total exposure of each element was calculated. The experiment results showed that the PAHs pollution was more serious in indoor air than outdoor. The percentage of five-ring and six-ring PAHs which were considered more carcinogenic in exposure area was higher than that of the background area. The average of daily total exposure amount to PAHs was 3.758μg/d for the exposure group while the control was only 0.257μg/d. Significant differences of the exposure amount of some trace elements were found between the two groups. The daily intake of cadmium and thallium of the exposure group were higher than that of the control group, while daily intake of selenium was lower in the exposure group than in the control. And intake of selenium in this area was severe deficiency. The intake of life elements such as iron, copper and zinc through food and drinking water were much lower than the recommended dietary allowance (RDA).
