CINCINNATIA multinational team of environmental and occupational health researchers has found that consumer paints sold in Nigeria contain dangerously high levels of lead.
Increased globalization and outsourcing of manufacturing has drastically increased the likelihood that products with unacceptably high levels of lead are being traded across bordersincluding between China and Africa as well as into regulated countries like the United States.
Researchers at the University of Cincinnati (UC) and University of Ibadan in Nigeria report these findings in an early Sept. 12 online edition of the journal Science of the Total Environment. Researchers believe the studyto be published in the December print issue of the journalis the first report of new consumer paint lead levels in Africa.
Nigerias recent economic recovery may lead to increased activity in the building industry and Nigerialike other African countriesis increasing trade with Asia, particularly in China, explains Eugenious Adebamowo, of the University of Ibadan and lead author of the study.
Its important that international regulations be in place to supplement local efforts to ensure that paints have lower than recommended lead levels, with the ultimate goal of eventually eliminating all lead from paint, she adds.
For this study, researchers analyzed lead levels in five colors of paint, from each of five brands, marketed and sold in Ibadan, a city of more than 2 million people in southwestern Nigeria. Each paint sample was applied in a single layer to a wood block, left to dry and then removed and analyzed in UC laboratories for lead content.
They found that 96 percent of the consumer paints available in Nigeria contained higher than the recommended levels of lead. Bright-colored paintsparticularly yellow, red, and green contained the highest levels. Respectively, lead levels in yellow, red and green paint were 10, six and three times higher when co
