ABSTRACTObjective. To find out whether the use of lead-glazed ceramic (LGC) is associated with blood lead levels in indigenous schoolchildren from Oaxaca, México. Materials and Methods. We evaluated LGC use at home as a primary source of lead exposure in 387 indigenous schoolchildren in Oaxaca in May 2001. Results. We found an adjusted difference of 3.9µg/dl (p‹0.01) in blood lead levels (BLL) among children reporting to use (82%) LGC at home vs those who didn’t. BL levels greater or equal than 10 and 20 µg/dl were observed in 60 and 27% of children, respectively. Conclusions. Lead poisoning from LGC use could remain a concern for public health in Mexico, where there is a need to provide care and further study to verify its effect on BLL.
