Dietary intake of total and inorganic arsenic by adults in arsenic-contaminated Dan Chang district, Thailand, using duplicate food approach.

摘要

Dan Chang district, approximately 100 km west of Bangkok, was a site of tin mines operated almost 40 years ago. Mining operations caused arsenic contamination in soil, surface water, and groundwater within the district. The specific aim of this study was to estimate the dietary intakes of total and inorganic arsenic in 60 adults (30 males and 30 females) residing in Dan Chang district, using a duplicate food approach. The daily intake rates of inorganic arsenic ranged from 0.496 to 1.817 mug/kg BW for males and 0.342 to 1.778 mug/kg BW for females.
