Abstract
Blood Lead, Urinary Lead and Urinary δ-Aminolevulinic Acid Levels among Children Living in Kinshasa, D R Congo: A Pilot Biomonitoring Study
Highlights
Lead is a heavy metal mainly in the earth’s crust
This study has reported a geometric mean blood lead of 120 μg/L (IC 95%: 115-125) and sixty-three percent of children aged less than 6-years-old with blood lead levels above 100 μg/L [28]
It was observed that 10% of children between 0 and 6-years-old, and 77% between 7 and 8-years-old had blood lead level of 136.93 μg/L and 108.45 μg/L respectively, 23% of children between 9 and 10-years-old and 17% between 11 and 12-years-old presented blood lead
Summary
Lead is a heavy metal mainly in the earth’s crust. Up to now, no health benefits to humans have been reported for this metal or its compounds. It is an environment toxic affecting deleteriously nervous, hematopoietic, skeletal, renal, endocrine and reproductive systems. It is classified in its inorganic form as possible human carcinogen (group 2A) by International Agency for Research on Cancer (IARC). Exposure to this metal in the environment continued to be a serious public health problem for all ages [1,2,3,4,5,6,7,8,9]. Children absorbed more lead from their environment and their developing central nervous systems are vulnerable to the toxic.
