Lead exposure at an early age substantially increases lead retention in the rat.
It has been hypothesized that the high rate of bone remodeling during childhood and the consequent high calcium and lead turnover result in a substantial reduction in bone lead stores so that much of the lead incorporated in bone during childhood does not persist into adulthood. We studied the effect of age at lead exposure on blood and organ concentrations of lead, calcium, and zinc 1-5 months...
متن کاملEarly asymptomatic lead exposure and development at school age.
Sixty-seven 7-year-old children, who had asymptomatic lead exposure between 1 and 3 years of age, were compared in their performance on a series of psychologic tests to 70 children of the same age and socioeconomic background who presumably did not have significant exposure to lead. Exposed children had deficits in global IQ and associative abilities, in visual and fine motor coordination, and ...
متن کاملEnvironmental lead exposure increases micronuclei in children.
The objective of this pilot study was to investigate the contribution of environmental exposures to lead in the development of cytogenetic damage detected as the frequency of micronuclei (MN) in children. The other aim was to apply the MN assay in combination with fluorescence in situ hybridization (FISH) using a pan-centromeric chromosome probe to elucidate the formation mechanism of induced M...
متن کاملPrimary Prevention of Lead Exposure—Blood Lead Results at Age Two Years
OBJECTIVES The Philadelphia Lead Safe Homes (LSH) Study was designed to evaluate whether educational and environmental interventions in the first year of life for families of newborns increased knowledge of lead exposure prevention and were associated with less elevation of blood lead levels (BLLs) for these children, when compared to children receiving standard care. METHODS The current stud...
متن کاملEnvironmental lead exposure during early childhood.
OBJECTIVE To determine the relative contribution of residential lead hazards to children's blood lead concentrations during early childhood. METHODS We enrolled children 6 months of age and followed them until 24 months of age. Blood and samples of dust, soil, water and paint were analyzed for lead at 6-month intervals, and interviews were conducted to estimate nutritional, behavioral, and de...
