In summary, there are several case reports that have implicated lead as a potential renal carcinogen in humans, but the association remains uncertain. Soluble salts, such as lead acetate and lead phosphate, have been reported to cause kidney tumors in rats. Lead affects primarily the peripheral and central nervous systems, the blood cells, and metabolism of vitamin D and calcium. Lead also causes reproductive toxicity. The public must be educated about the dangers of lead. Families must learn how to protect themselves from occupational and environmental sources of lead. Schools have responsibilities in raising public awareness to help prevent lead poisoning. It must also help to build a network of support for developing and sustaining lead poisoning prevention programs.
Since we now know that the neurological damage caused by even low levels of lead is long term and often irreversible, it is no longer acceptable to only identify and attempt to treat already poisoned individuals. The only solution to lead poisoning is to prevent it by controlling lead hazards in the environment before poisoning occurs. Therefore, educators must take an active role in educating the nations teachers and children of the chemically contaminated communities and must warn of the consequences of ignoring the chemical threat of lead in our environment. Schools must structure curriculum that promote a non-toxic environment for all. The role of teachers, parents and communities is to protect its young by having a healthy, safe and orderly environment for all of its children. We must rally around policies, practices and ethics to achieve that end.
