Air sampling devices

Integrated Sampling Device an air sampling device that allows estimation of air quality components over a period of time (e.g., two weeks) through laboratory analysis of the sampler s medium. 

Farm worker exposure to pesticides has been studied extensively over the past 30 years.This scientitic discipline has evolved from the days when respiratory exposure of farm workers was measured using gauze dosimeters placed inside respirators to collect airborne pesticide residues to very sophisticated air sampling devices and remarkable dosimeter devices to measure dermal exposure to farm workers. ... 

In some cases, direct measurements of contaminant exposure may be made, such as in the assessment of the steady-state release of an established hazardous waste source. Groundwater monitoring wells or air-sampling devices can be used to determine current exposure concentrations for exposed populations. Commonly, however, air, surface water, and groundwater sampling is neither a logical nor a practical choice. Typical situations in which sampling is not feasible include (i) the evaluation of future exposme and risk to potentially exposed populations and (ii) the potential risk from an event that has yet to occm (e.g. a hazardous waste spill).

The Instruments Product Group also is the secretariat for two American national standards. ANSI/ ISEA I02-I990 (R2009) for gas detector tubes and ANSI/ISEA I04-I998 (R2009) for diffusive type air sampling devices, or passive monitors. Although both standards have been around for awhile, they both were reaffirmed in 2009. The ANSI/...
