The number and percentage of Baltimore children with elevated levels of lead in the blood continued to decline last year, state and city health officials reported yesterday.
Overall, 624 children, or 3.5 percent of those tested, had lead levels greater than 10 micrograms per deciliter, compared with 4.6 percent in 2006, according to the Maryland Department of the Environment. Thanks to lead abatement programs and education, the proportion has been declining steadily since 1998, when it was 22 percent.
On the down side, 85 children suffered from lead levels of 20 micrograms or more, compared with 69 the previous year.
