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 thicknesses and types can be adapted to target specific compounds.

Apparatus and method for filtering and sampling airborne respiratory

The disclosure herein relates to antigens, antibodies, antisera and diagnostic assay kits used in an enzyme-linked immunosorbent assay (ELISA) for .alpha.-haloacetamide herbicides.

Immunoassay for the detection of .alpha.-haloacetamides

A method is disclosed for stimulating the immune system of a warm-blooded animal by the production of antibodies by administering an effective amount of Cytophaga allerginae lipopolysaccharide endotoxin.
