South-side children have greatest exposure to lead in Chicago, health department data shows


This interactive heat map, compiled using Chicago Department of Public Health data, GIS files, and Google Fusion, shows where Children with the highest rates elevated blood lead levels in Chicago live. Data is from 2010.


Chicago Department of Public Health data shows that children in the poorer, industrialized south of Chicago are more likely to have dangerous levels of lead in their bodies than children in more affluent neighborhoods.

The data, obtained by a FOIA request from the health department, shows the levels of lead the agency found in children 17 and under in the city of Chicago. Most children tested for lead, however, were under 6 years old.

“An EBL or elevated blood lead level, is defined… as the child’s highest venous test with a result of 6 or more micrograms lead (Pb) per deciliter blood,” the health department wrote.

According to the EPA, there is no safe level for lead in the human bloodstream. At 10 micrograms per deciliter of blood, children can develop symptoms such as “lowered intelligence, reading and learning disabilities, impaired hearing, reduced attention span, hyperactivity, and antisocial behavior.”

The most recent results are from 2010, but the file contains annual results back to 2005. They were compiled with the help of an epidemiologist in the department.

“Multiple blood lead tests were determined using an algorithm that matches children by name, date of birth and sex, while allowing for common typographical and data entry (eg, reversing first and last name) errors for blood lead tests conducted within a calendar year,” the health department wrote.

In the interactive heat map at the top of the post shows the rate at which children in each of Chicago’s 77 communities reported elevated levels of lead.

The Englewood community has the highest EBL rate, where 9.15 percent of the children who were tested for lead came back with a positive EBL. Neighborhoods in the north end of Chicago had EBL rates between 0.8 percent and 3.31 percent.

The People VS the Bottom Line - BATTLE IN THE BARRIO part 3/4


“Decisions regarding whether or not to proceed with the above projects or other approaches to compliance remain subject to a number of factors, such as market conditions, regulatory and legislative developments, and forecasted commodity prices and capital and operating costs applicable at the time decisions are required or made… Due to existing uncertainties about these factors, Midwest Generation intends to defer final decisions about particular units for the maximum time available. 
- Excerpt from page 92 of Midwest Generation’s 2010 report to the Securities and Exchange Commission, form 10K.

NOTE: The following is the third installment in a series of four stories about the environmental and health impact of coal-fired power plants on densely-populated, low income Chicago communities. It's called "Battle in the Barrio: the Struggle in Chicago's Pilsen Neighborhood Against Pollution." Part one, "Four Sisters, One Rare Disorder," is available here. Part two, "Old Problems, New Attention" is available here. A visualization describing Pilsen's struggle with pollution is here.

South-side children have greatest exposure to lead in Chicago, health department data shows


In a dimly-lit space in the back of a Pilsen café known for its fruit smoothies, a dozen Pilsen Environmental Rights and Reform Organization (PERRO) activists and organizers huddled over coffees and discussed upcoming plans for an annual community festival, Fiesta del Sol.

A Pilsen tradition for the last 39 years, Fiesta del Sol is an event featuring local art vendors, Mexican food, carnival rides, soccer games, and a chance for local organizations to boost donations and deliver information to the public.

This year, as in years past, Midwest Generation was one of the lead corporate sponsors for the event, and included among a group of sponsors under the banner “Pilsen Neighborhood Community Counts.”

“Let me just say one thing,” Jerry Mead-Lucero said. “There was some discussion about whether we should do something at the Fiesta because of the whole connection with Midwest generation. What I’ve been suggesting is I don’t want to completely piss off Pilsen Neighbors about having a booth there, so I’m not recommending we do something like a direct action in a Fiesta.”
