| Research Abstract |
The effects of long term exposure to arsenic on IQ (IntelligenceQuotient) or SC (social competence) of Bangladeshi children, who have been drinking arsenic-contaminated groundwater, were examined with more than 200 subjects in each agegroup of 4-5 years, 9-10 years, and 14-15 years old. Children who have been highly exposed to arsenic (those with high urinary arsenic concentration) showed lower IQ and SC scoresin each age group. The relation was consistent after controlling for parents’socioeconomic conditions (income, education and occupation). Therefore, exposure to arsenic (drinking arsenic contaminated groundwater) from early stage of life was considered to be critical for the mental and social development.
