In this study,we searched multiple databases for all relevant original articles(1996-2013).To investigate blood lead levels(BLL)and possible risk factors for lead exposure among children in China A total of 388 articles met our inclusion criteria.The overall geometric mean(GM)BLL was 71μg/L,and the prevalence of elevated BLL(EBLL,defined as BLL≥100μg/L)was 18.48%among children.The prevalence of EBLL remained significantly higher
