A team of researchers has confirmed that seasonal fluctuations in blood lead levels found in children in urban areas throughout the United States and elsewhere in the northern hemisphere are the result of resuspended dust contaminated with lead. The researchers were led by Shawn P. McElmurry, Ph.D., P.E., assistant professor of civil and environmental engineering in Wayne State University's College of Engineering.
The study, published in the journal Environmental Science and Technology was based on nine years of data on more than 367,000 children in Detroit. The team of scientists stated the results support the critical need for controls for lead exposure in children.
Any Connection Between Lead Poisoning and Juvenile Crime?
Lead is a common element but is found in old paints (including those once used on children's toys), soil, old piping, water, and the atmosphere from lead-containing vehicular fuels,

"The study aimed to address a critical gap in understanding why child blood lead levels vary seasonally," said McElmurry. "What we have done is demonstrate that increased blood lead levels in the summer are connected to increased amounts of soil and dust contaminated with lead. This soil is resuspended into the air to a greater extent during the summer than during the winter, hence showing decreased lead levels in children during the winter months."
According to McElmurry, the results of this study place a greater importance on soil contaminated with lead and the need to come up with better remediation to improve children's health.

A local industrial park is being accused by parents of causing lead poisoning in their children, Chinese state media said Monday.
"Our findings suggest that more attention should be focused on the resuspension of soil contaminated with lead," said McElmurry. "Current efforts focused on lead-based paint have generally been ineffective in reducing the average child's exposure to lead, and our research team recommends primary attention be given to preventing lead exposure from lead-contaminated soil."
