Claremont School District is requiring all students entering kindergarten and pre-k this fall to be tested for lead poisoning. Claremont health officials recommend that all children be screened because of the amount of older housing in the district. Over 60 percent of homes in New Hampshire were built before 1978 when the federal government banned lead paint use. It is the oldest housing stock in the US. Lead paint can be poisonous to children even in small amounts. Low levels of lead poisoning are associated with decreased intelligence, behavior problems, reduced physical stature and growth, and impaired hearing. The only way to know for sure if a child has lead poisoning is a simple blood test. To learn more about lead poisoning visit New Hampshire Department of Health and Human Services.
