Abstract: BACKGROUND & AIM: To investigate umbilical cord blood chrome level of newborns in Guiyu town,an e_waste recycling area,and to discuss the effects of e_waste on newborn's health. MATERIALS AND METHODS: 152 full_term newborns belonged to two groups, one group from Guiyu (Guiyu group,n=100) and another group from other neighboring towns (control group,n=52). The chrome level of umbilical cord blood was determined with graphite atomizer absorption spectrophotometer. Questionnaires for mothers were used for analysis of related factors. RESULTS: Compared with the control group (20.30 μg/L), the geometric mean of chrome level 303.38 μg/L in the Guiyu group was significantly different (P<0.01). The Guiyu group of newborns with relatively high chrome levels in umbilical cord blood were from pregnant women who were working with e_waste recycling. CONCLUSION: There were close relationships between the Guiyu group of newborns with relatively high chrome levels in umbilical cord blood and local e_waste recycling activities as well chrome pollution locally. Environmental chrome pollution could threaten the children's health around the recycling site.
