How Reliable Are Exposure Estimate Techniques?
This month's Journal of Occupational and Environmental Hygiene has several interesting articles. If you're looking for confirmation of the worry that expert subjective or quasi-quantitative (e.g. task based) exposure estimation techniques don't produce anything that has much to do with reality see:
"Evaluation and Comparison of Three Exposure Assessment Techniques"
If you want an estimate of benzene exposure above 1 ppm from mineral spirits containing less than 0.1% benzene wt/wt see:
"Estimating Airborne Benzene Exposures from Air Monitoring Data for Mineral Spirits"
If you wonder why historical data on asbestos exposures from joint compound don't jibe with data from recent efforts to measure exposures using recreated asbestos-containing joint compound from old formulae see:
Finally, if you want to know what variables influence dust in the breating zone of drywall sanders see:
"Factors Influeincing Dust Exposure: Finishing Activities in Drywall Construction"
Always remember, what you see depends on how you look as much as where you look.
