BACKGROUND: Electronic waste (e-waste) recycling has remained primitive in Guiyu, China, and thus may contribute to the elevation of blood lead levels (BLLs) in children living in the local environment. OBJECTIVES: We compared the BLLs in children living in the e-waste recycling town of Guiyu with those living in the neighboring town of Chendian. METHODS: We observed the processing of e-waste recycling in Guiyu and studied BLLs in a cluster sample of 226 children 10 microg/dL, compared with 37.7% of children (23 of 61) in Chendian (p < 0.01). In addition, we observed a significant increasing trend in BLLs with increasing age in Guiyu (p < 0.01). It appeared that there was correlation between the BLLs in children and numbers of e-waste workshops. However, no significant difference in Hgb level or physical indexes was found between the two towns. CONCLUSIONS: The primitive e-waste recycling activities may contribute to the elevated BLLs in children living in Guiyu.
