Exposure, occupational surface contamination

The relative contributions of the exposure routes and sources are as follows. For persons exposed to isophorone in the workplace, total doses will probably be substantially higher than those exposed only to ambient air and drinking water, and their inhalation and dermal exposures for the occupationally exposed can be assumed to result exclusively from the workplace exposures. Inhalation and dermal exposure for persons not exposed to isophorone in the workplace will most likely result from showering or bathing, but only in locations that receive their drinking water from contaminated surface water sources. These exposures are expected to be very small. In locations that do not have the potential for isophorone in the drinking water, any ingestion, inhalation, or dermal exposure is unlikely. 

Methods for Determining Parent Compounds and Degradation Products in Environmental Media. Human exposure to diazinon occurs via inhalation of ambient air ingestion of contaminated food and water and dermal uptake through occupational and non-occupational contact with contaminated soils, surface water, and commercial preparations. Methods have been reported for the measurement of... 

If DOD s occupational exposure limit for lead is lowered, surface and skin decontamination are likely to play an even more important role in effective control of employee exposures than in the past. It will be important for an updated guideline to address the importance of decontamination in more detail and with greater precision. Where possible, quantitative levels of contamination should be included in guidelines rather than qualitative statements regarding the importance of housekeeping.
