For the current study, Clark analyzed a total of 373 new household enamel paint samples of various colors and brands from 12 countries in Africa, Asia and South Americawith a minimum of 10 samples from most countries included in analysis. His goal was to determine the amount of lead and how it compares to U.S. standards. His team also analyzed the consumer cost of leaded and unleaded paint.
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. Researchers determined that 73 percent of the paint companies' products tested had lead concentrations exceeding current U.S. standards.
In September 2006, Clark's team published what is believed to be the first scientific report to show that unregulated Asian countries produced and sold new consumer paints that greatly exceeded U.S. lead safety levels. In that study, 75 percent of the consumer paint samples tested from countries without controls including India, Malaysia and Chinahad levels exceeding U.S. regulations.
"Although lead poisoning of children is widely recognized as a major public health problem, too little attention is being given to correcting the problem in many parts of the world," says Clark. "Meanwhile, thousands of children continue to be poisoned by the metal, setting them up for life-threatening problems later in life.
"Our studies have shown that when comparing the prices of the same size can of paint produced by several companies within India with a wide range of lead concentrations, there is no significant consumer price difference between leaded and unleaded consumer paint," says Clark.
Their research showed that one large multi-national company produced low lead paint in each of the countries where it was sampled and another company was found to have stopped using lead in paints in one country during
