Nearly 1,400 new cases of lead-poisoned children under age 6 were reported in Connecticut in 2015, a slight drop from the year before, but more children showed higher levels of poisoning. A child whose blood test shows 5 micrograms of lead per deciliter or higher is considered poisoned. The 2015 numbers show 98 new cases of children with lead levels of 20 micrograms or higher, four times the threshold number and a 32 percent jump from 2014. “We cannot, with any certainty, explain why this is the case,” said Krista M. Veneziano, coordinator of the Connecticut Department of Public Health’s (DPH’s) Lead, Radon, and Healthy Homes Program, about the disproportionately larger numbers of higher toxicity. Exposure to lead can damage cognitive ability, including a measurable and irreversible loss in IQ points.
Nearly 1,500 children under the age of 6 tested positive for lead poisoning in 2014, according to the latest numbers from the state Department of Public Health. Overall, the number of lead-poisoned children in Connecticut was about the same in 2014 as in 2013, with the total rising by 9 children. In 2014, 2,284 children under 6 were diagnosed as lead-poisoned, compared with 2,275 in 2013. The numbers are roughly equal because some children diagnosed with lead poisoning are cleared after being treated for it, they turn 6 and so are no longer followed by the state, or their families leave the state. But at a combined hearing of the legislature’s Committees on Children and Public Health on Monday, a state Department of Public Health official conceded that those numbers and other state lead statistics may be misleading because of the deficiencies of lead screening in Connecticut.
