Children in 323 neighborhood areas in Los Angeles County have lead levels at least as high as found in Flint, Michigan. Some have levels at least twice as high. Reuters has examined the results of more more than 15,000 tests on child lead levels taken between 2011 and 2015 by the Los Angeles County Department of Public Health. The results of that analysis are worrying for L.A.'s children and parents.
In Lead's Hidden Toll Reuters examines the areas of Los Angeles with the highest levels of lead and explores some of the reasons why these levels might be high. The article is illustrated by an interactive map which shows the levels of lead found in children in each census tract area. You can click on each neighborhood on the map to view the number of tested children and the percentage found with elevated levels of lead.
Lead's Hidden Toll and the interactive map are part of Reuters' nationwide investigation, Off the Charts. The map not only show the levels of lead found in L.A.'s children, it also allows you to view the results of childhood blood lead tests in 21 different U.S. states.
