由于大量的非正式电子垃圾(电子垃圾)回收活动，贵屿是中国铬污染最严重的地区之一。对贵屿和对照地区的711名儿童进行了为期3年(2004年、2006年和2008年)的独立横断面研究。使用父母/监护人填写的问卷来评估铬暴露的危险因素，而体检仅用于2008年，以评估长期接触铬对儿童身体发育的影响。与2004年至2008年同期的陈店儿童相比，贵屿儿童的bcr水平显著升高(P<； 0.001)。与儿童BCR水平升高相关的主要危险因素包括将房子用作家庭作坊、父母参与电子垃圾回收以及贵屿儿童住所。高铬暴露组儿童体重和胸围高于低铬暴露组(P<； 0.0 1)，两组男童体重和胸围差异不显著(P<； 0.0 5)。这一结果表明，非正式的电子垃圾回收活动导致贵州省儿童BCR升高，可能威胁到儿童的健康，并对身体生长发育产生影响。
Guiyu is one of the most heavily chromium-polluted areas in China due to the numerous informal electronic waste (e-waste) recycling activities. A 3-year (2004, 2006, and 2008) independent cross-sectional study on blood chromium (BCr) levels of 711 children from Guiyu and a control area was investigated. Questionnaire completed by parents/guardians was used to assess the risk factors of chromium (Cr) exposure, while physical examination, for the year 2008 only, was used to evaluate the effects of long-term exposure to Cr on child physical development. Children living in Guiyu had significantly higher BCr levels compared with those living in Chendian at the same period from 2004 to 2008 (P< 0.001). The predominant risk factors related to elevated child BCr levels included the use of house as a family workshop, parent involved in e-waste recycling, and child residence in Guiyu. Children’s weight and chest circumferences in group with high exposure to Cr (upper quartile) were higher than in the low-exposure group (P< 0.01), although the difference was less significant for boys between the two groups (P< 0.05). The results suggest that elevated child BCr in Guiyu due to informal e-waste recycling activities might be threatening the health of children, with implications on physical growth and development.
