Sample Collection and Analysis
A limited number of products associated
with case households, such as
cosmetics, spices, and remedies, were
purchased in the camps. Several identified
as possible risk factors for EBLL
in the case-control investigation were
tested for lead at the Applied Technical
Services laboratories (Marietta, GA) in
August 2009. During a previous visit in
January 2009, samples from the major
water sources supplying each of the 3
camps were collected and tested for
lead at UAE laboratories (Bangkok,
Thailand); levels were below or nearly
below limits of detection (,0.5 ppb).
