Local Positioning System for Exposure Assessment and Control Researcher:

An anodic stripping voltammetry instrument has been developed by ESA, Inc., Chelmsford, MA, in conjunction with CDC. This instrument provides a prompt, cost-effective technique to monitor lead exposures for pediatric screening. Although this instrument has only been used with children whose blood lead levels are significantly lower than in exposed adults, its capability to analyze blood quickly on-site makes it potentially valuable to occupational health professionals during on-site investigations, particularly with highly transient workers such those in construction. We will compare instrument results with split samples analyzed according to CDC’s Whole Blood Method 1080C from adult populations exposed to high lead levels. The practicality and cost-effectiveness of using this instrument in the workplace will be assessed and its precision estimated.
