ABSTRACT:
A combination respiratory filter and sampling device has been developed which collects airborne contaminants for respiratory exposure measurements. The devices, which fit existing commercial half-mask respirators, are generally smaller and lighter in weight than existing filters, and have low resistance to airflow, so they can be comfortably worn by people performing their normal work duties. Each device consists of at least a front, a middle and a back section which can be independently separated and analyzed by traditional laboratory techniques. The filtering and sampling media thickness and types can be adapted to target specific compounds.
