RAPID HIGH RATE LEAD-IN-AIR MONITOR FOR USE AT FIRING RANGES

The development of a simple, reliable, and easily operated system to detect and measure airborne lead (Pb) to trace levels is the subject of the Phase I effort. Lead is toxic to humans at very low levels and is ingested easily by breathing air in which elemental Pb or compounds of this element are dispersed. In firing ranges there is an opportunity for shooters and range personnel to be exposed to hazardous levels of lead and its compounds. Control of Pb levels in firing ranges typically depends on adjusting ventilation to limit Pb buildup. This control strategy depends on the ability to monitor Pb levels in the air if maximum energy efficiency in use of fans and maximum heat conservation is to be achieved. The Phase I real-time monitor for Pb levels in firing range air will provide a monitor to protect human health for those using the range and provide a continuous monitor suitable for ventilation control to assure that acceptable Pb levels can be reached and maintained. After successful demonstration of the monitoring technology for trace levels of Pb in air during Phase I, the project will proceed to development and testing of a prototype analyzer at operating firing ranges in Phase II. The results of the prototype testing will serve as the basis for a commercial lead-in-air analyzer to serve a market, expanded beyond just firing ranges, in Phase III.
