Most cases of lead poisoning in the United States occur among children who
eat chips of lead-containing paint that have peeled off the ceilings and
walls of old buildings. Lead paints were widely used for home interiors
until the 1940's, and in many city slums, where buildings have been poorly
kept. 15 per cent to 20 per cent of the children between the ages of one and
five show evidence of lead ingestion. It is estimated that 3 per cent to 5
per cent have potentially toxic levels of lead in their blood. In many large
cities, hundreds of cases among children are reported each year, but it is
believed that the actual number may be much higher. In industries that use
lead or lead components, lead poisoning among workers is a potentially
serious hazard, but present control measures are so stringent that cases of
industrial poisoning are rare. Symptoms of lead poisoning develop slowly
after several months of lead ingestion. Early symptoms are mild diarrhea,
anemia and irritability. As the level of lead rises, stupor and convulsions
occur, often leading to death. The prevention of lead poisoning is therefore
of prime importance. An effective measure program includes making the public
aware of the danger, testing paint in dilapidated buildings, examining
children for evidence of lead ingestion, and keeping children out of unsafe
houses. Stringent checks on the level of lead discharged from motorized
vehicles and factories should be regularly carried out. |

Cases of lead poisoning occur among children who eat chips
of lead-containing paint peeled off from ceiling and walls of old houses.
This is especially so in slums and large cities in industries that use lead
or its components, workers are also exposed to lead poisoning. The symptoms
include diarrhea, anemia, irritability and convulsions. To curb lead
poisoning, awareness campaigns should be carried out. Children should be
checked for lead ingestion. Paint in old buildings and discharges from
vehicles should be monitored closely. ( 86 words ) |
