METHOD AND APPARATUS FOR FLUOROGENIC DETERMINATION OF LEAD CONCENTRATION

摘要

A method and apparatus for the use of fluorogenic probes for development of a rapid, and cost-effective determination of lead clearance following lead hazard control activities. The invention involves the use of fluorogenic chemosensors for efficient detection of lead in dust on hard surfaces at regulatory levels. The use of methods for lead visualization based on one or more of the fluorogenic type compounds would be highly beneficial to lead abatement projects. The identification of areas of high lead concentration (hotspots) can allow work to be focused on areas that have the greatest impact on clearance. Also, a rapid and cost-effective means of determining if lead clearance has been met can improve compliance with lead abatement activities. This would decrease the amount of time and materials spent in general surface cleaning and allow the elimination of isolated areas of lead concentration that may otherwise have been missed.
