This study aims to assess the health risk of exposure to heavy metal contaminated in soil samples of operators who work at waste electrical and electronic equipment sorting and retail shops which was conducted in Ban Daeng Yai Sub-district, Ban Mai Chaiyaphot district, Buriram Province. Soil samples were collected by using the Judgement/Biased sampling method from 77 retail shops and the amount of heavy metal was analyzed by the X-ray Fluorescence Spectrophotometry technique and Atomic Absorption Spectrophotometry (AAS). Independent Samples Test (t-test) was selected to compare statistical differences of heavy metal content in soil detected by both analytical methods. The results showed that there was no difference found for copper, lead, and zinc contents (statistical significance level of 0.05); but the analytical results of cadmium, nickel, manganese, and chromium were different (statistical significance level of 0.05). The correlation to arsenic could not be conducted because they were not detected. The risk assessment of exposure to heavy metal contamination resulting from electrical and electronic equipment sorting and detected by both analytical methods found no harmful health effect. However, retail shop owners should be well aware of the dangers and request staff to wear personal protective gear during working hours. In addition, Daeng Yai Subdistrict Administrative Organization should provide a proper purchasing procedure and handling method for retail shop owners on a regular basis.
