Childhood lead exposure is costing developing countries $992 billion annually due to reductions in IQs and earning potential, according to a new study published today.<\/p>\n
The report by New York University researchers is the first to calculate the economic cost of children exposed to lead in Africa, Asia, Latin America and other developing regions. The researchers found that, despite major declines in exposure in the United States and Europe, lead is still harming brains and bottom lines in poorer regions around the world.<\/p>\n
The toxic metal is annually taking a 1.2 percent chunk out of the entire world\u2019s gross domestic product, according to the new report.<\/p>\n
\u201cChildhood lead exposure represents a major opportunity lost,\u201d said Dr. Leonardo Trasande, a professor at New York University School of Medicine and senior author of the study published online in Environmental Health Perspectives. \u201cPrevention may actually accelerate economic development, which is critically needed in these countries.\u201d<\/p>\n
Low levels of lead affect children\u2019s IQs, their ability to pay attention and how well they do in school. It also has been linked to violent and antisocial behavior.<\/p>\n
The researchers found that Africa\u2019s economy is harmed the most, with annual economic losses estimated at $137.7 billion, or 4 percent of its gross domestic product \u2013 a number that represents a country\u2019s economic output and financial health. Lead exposures cause annual estimated economic losses of $142.3 billion in Latin America, which is 2 percent of its gross domestic product, and $699.9 billion in Asia, which is 1.88 percent of its gross domestic product.<\/p>\n
