Essay on Lead Poisoning

Lead is a heavy metal which is naturally found on earth’s crust. It is a piece of metal which is malleable, has low melting point and has high corrosion resistance. The problem with lead, however, is that exposure to it by ingestion, inhalation and absorption through the skin is highly poisonous and toxic.

Research shows that the problems of lead poisoning have reached an alarming stage, especially in developing countries. According to the World Health Organization, it is estimated that at least 15 to 18 Million children in developing countries are suffering from permanent brain damage because of lead poisoning. In India, studies show that over 50% of the children below the age of 12 years in urban environments have unacceptable blood levels of 10 mcg/dl or more which indicates a high level of exposure to lead.

Various researches have shown that even low levels of exposure to lead have serious side effects, especially to children. Among the recognized side effects of lead poisoning are reduction in IQ and attention span, reading and learning disabilities, hyperactivity and behavioral problems, impaired growth and visual and motor functioning and hearing loss. At high levels of exposure lead poisoning in children may cause anemia, brain, liver, kidney, nerve and stomach damage, coma, convulsions, or even death.

Indeed, the problem of lead poisoning is a serious cause of concern for every country. Considering that lead is non biodegradable, it exists and will continue to exist not just in our soil, or in the air or in our drinking water but also in our homes. Lead poisoning affects people of all social and economic classes.
