Dangerous Lead-based Paint Common Around the World
A new study shows that lead-based paint remains a worldwide threat to public health. Paint containing lead is a major cause of lead poisoning in children.
The heavy metal enters the body when children breathe the paint dust or fumes in the air. Or when babies put their mouth on painted surfaces or swallow pieces of paint.
Lead can damage the brain and the nervous system. It can decrease intelligence, create behavior problems and slow a child’s growth.
Researchers tested new household paints from twelve countries in Africa, Asia and South America. The paints were sold under different brand names. The study found that almost three-fourths of the brands had dangerously high levels of lead.
The professor says high quality paint can be produced without lead. He and his team are calling for a worldwide ban on lead-based paint. He says many parts of the world are doing too little to correct the problem of lead poisoning in children. He notes that research has found no safe level of lead.
