... ELEMENTAL DETECTORS Phosphorus Methods exist that are specific for phosphon~s-containing compounds such as phosphate ester pesticides and organophosphate esters that are used as additives in certain fluids. Instrumentation Is Positive but expensive.
From page 317...
... Instruments using electrical charge include commercial smoke detectors as well as more technically sophisticated electrical aerosol analyzers. Smoke detectors employ an ionizing radiation source to generate electric charge on particles, and the resulting change in electric current is used to sense the presence of particles in air.

... For example, it has been demonstrated recently that alkyl phosphate compounds are present in the urine of workers exposed to organophosphate pesticides (WHO ~ 996; Lauwerys and Hoet ~ 993~. These pesticides are chemically similar to the phosphate esters commonly used as additives in hydraulic fluids and lubricating fluids employed in aircraft engines and auxiliary power units, and identified as possible causes of neurological problems in cabin crew members (Centers ~ 992; Craig and Barth ~ 999; Crane et al.

... Although this procedure would provide useful objective infonnation regarding the recent exposure history for Each individual providing a sample, biological sampling also has certain negative attributes. These negatives include necessary invasion of pnvacy, need to obtain informed consent, and the additional effort required to keep confidential the date resulting from analyses (Schulte and Sweeney ~995~.
