Environmental lead exposure in Polish children: blood lead levels, major sources and principles of the lead poisoning prevention.
In Poland, children are exposed to lead from the combustion of leaded gasoline and industrial processes. Since the early 1990s, emission levels have declined, and a ban on leaded petrol is anticipated in 2005. Major industrial sources are located in Silesia Province and the copper mining centre (Legnica region). Concerns about, lead exposure in children date back to the 1980s; mean blood lead levels (BILL)reported in children living near lead smelters in Silesia exceeded 20microg/dl. in the 1990s, mean BLLs were decreasing, both in urban children and those living near lead industry. Lower than the CDC action level of 101microg/dl, they were however higher than mean values in children from the other countries, where leaded gasoline had already been banned. Childhood lead poisoning prevention requires a comprehensive approach, involving different sectors. Medical prevention focuses on the early detection of exposed child by the blood lead testing and individual case management. An increasing body of evidence, indicating adverse effects even below the current "safe" level of 101microg/dl, argues for intensification of the primary prevention, which requires legal, economic and technical measures. Public health efforts should contribute to the reduction and elimination of sources of exposure in child's environment and public education campaigns.
