Chemistry 310/311 Fall 2001
Mission Determine if soils near Sherwin
Williams White lead factory (10909 S. Cottage
Grove) listed as EPA site in the neighborhood of
Pullman, Chicago are elevated in lead as compared
to other areas of Chicago. This area is not
overall high for reported lead poisoning
cases deriving from leaded paints (see map at
http//www.luc.edu/depts/chem/faculty/fitch/fitch
group /Service_Learning/Lead_in_Chicago/lead_in_ch
icago.html) but was the site of numerous white
lead paint factories. The paint factories
located in this region in the late 1800s as part
of the industrial boom based on railways in
Chicago.

Sampling Procedure
10 samples acquired at the factory site 12
samples acquired in the surrounding vicinity up
to 2 miles distant. See next slide
1. 3 foot square, grab samples at surface in each
corner and in center, bag. 2. Dry 3. Split
into 4 1 gramsubsamples. 3 serve as replicates
of digestion. 1 serves as a lead spiked
control. Spiked with 100 ug of lead.
Recovery Solution blank 104 Soil
spikes 170-132 soils were much more
variable in recovery. Soil samples with gt35
relative standard deviation were omitted from
the final report.
