RT Report T1 Childhood Exposure to Environmental Lead: MARC Report Number 34 A1 United Nations Environment Programme, A1 Monitoring and Assessment Research Centre, A2 Brunekreef, B. K1 environmentally hazardous substance K1 environmentally hazardous activity K1 child K1 lead contamination K1 epidemiology K1 air pollution K1 child health SN 0-905918-31-2 YR 1986 FD 1986 LK https://wedocs.unep.org/handle/20.500.11822/27888 UL https://wedocs.unep.org/handle/20.500.11822/27888 NO Considerable attention has been given to evaluating the significance of environmental pollution by lead. It has long been known that lead in sufficient quantities is a neurotoxin, but whether general environmental sources can result in the build-up and transfer of lead to an extent which might cause serious damage to human health is a question yet to be answered. Recent studies suggest that adverse health effects can occur at blood lead levels which are lower than the levels previously considered safe. In this report, the exposure of children to environmental lead is discussed, along with the impact of environmental lead exposure on the concentration of lead in children's blood.
