which the XRF model could reliably determine the presence of lead) was used to evaluate
the results. The Niton consistently identified the presence of lead spectra emissions and
gave quantitative readings above 10 ppm for the nine samples with lead content that
exceeded 10 ppm in laboratory testing. The authors’ study suggests that the Niton
XLp303A is an effective screening method for food and similar items with lead content
≥10 ppm, provided the operator is trained to identify lead spectra. Rapid, on-site
identification of lead exposure sources allows an investigator to inform the family of
immediate steps they can take to decrease their child’s lead exposure.
State Public Health Laboratory Biomonitoring Programs: Implementation and
Early Accomplishments

In 2009, the Centers for Disease Control and Prevention funded three state-based
public health laboratory biomonitoring programs. These programs are the foundation for
a National Biomonitoring Plan that consists of a larger network of state and local
biomonitoring programs. To understand the utility of these programs and plan for the
larger network, interviews were conducted with the program officials. The goal was to
gather information on the challenges, successes, and lessons learned in program launch
and implementation. Representatives of all programs participated. Projects range from
statewide efforts to focused community investigations. Each program focuses on specific
analytes including metals, pesticides, and other organics. Main accomplishments reported
include development of laboratory and field capacity as well as generation of analytical
results. Common challenges reported were laboratory setup and operation, sample
collection and logistics, and staff recruitment. Respondents made specific
recommendations for improving effectiveness of the current programs as well as ways to
advance the National Biomonitoring Plan.
Evaluation of Metal Impurities in Foods Preserved With Sodium Lactate
Kimberly Ferren Carter, PhD, RN

The public is being bombarded by the media almost daily with real and potential
food health concerns leading to a public sentiment that questions the vulnerability and
quality of our food. Sodium lactate is a food-grade product that in recent years has been
used in bioremediation to stimulate microbial growth and contaminant breakdown
processes. In previous work, impurities including arsenic and chromium were discovered
to be present in the sodium lactate concentrate. The study described in this article was
performed to determine whether arsenic and chromium were at detectable levels, posing a
potential concern in food products preserved with sodium lactate available to the general
public. A pilot sampling of three sodium-lactate-preserved food products was obtained
