To investigate the influence of lead pollution in SY River on children's intelligence and provide a scientific data for governance of the SY River and protection of the residents, especially children. The polluted area and control area were selected randomly from less than 5 km and more than 20 km away from the SY river basin, respectively. Concentrations of lead in the river water, drinking water, soil, grain and vegetables were measured by atomic absorption spectrophotometer (flame technique). There were 154 children, aged from 8 to 13, were recruited from two areas. Combined Raven's Test (CRT) was used to measure the intelligence of the children. The concentration of lead in SY River was exceeding the standards of surface water quality. Compared to the control area, the concentrations of lead were significantly higher in the polluted area among drinking water, soil and vegetables (P<0.05). Blood lead levels were significantly higher in children who were living in polluted area than those living in control area (P<0.05). Similarly, children who were living in polluted area had significantly lower IQ than those living in control area (P<0.05). After controlling for confounders, an inverse association was observed between blood lead concentration and IQ scores (beta=-0.293, P<0.05). These data suggested that the lead pollution in SY River were still serious and had entered the body by soil, drinking water and vegetables. Finally, our study suggested that environmental lead exposure had affected the children's intelligence to a certain extent. [Tang CY, Li AQ, Huang H, et al.
