This study measured and analyzed the heavy metal (Cd, As) content of fine dust in the city of Gwangyang, Jeonnam from September 19 to September 22, 2016. For cadmium, the arithmetic average was 0.21 ng/m3 (0.12~0.49 ng/ m3), which did not exceed the WHO\'s recommended level. The average of arsenic was 2.41 ng/m3 (0.30~142.08 ng/ m3) and the geometric mean was 11.18 ng/m3, which exceeded the WHO\'s recommended standard in 16 out of 24 measurements. In the case of cadmium, the CTE of male was 9.22 × 10−8 RME 1.91 × 10−7 and the female CTE was 9.44 × 10−8 RME 1.92 × 10−7, which did not exceed the EPA limit of CTE 2.18 × 10−5 RME 1.51 × 10−4 for men and CTE 2.23 × 10−5 RME 1.51 × 10−4 For women, CTE 2.23 × 10−5 RME 1.51 × 10−4 results were obtained, which exceeded the EPA\'s recommended limit and also exceeded the maximum allowable limit of 10-4.
