Additionally, there are long-term tubes designed to measure exposures over an extended period such as an 8-hour work shift; these operate using a batterypowered pump or as passive samplers relying on diffusion. With battery-powered pumps, several detector tubes (or detector tubes plus an adsorption tube) can be connected via a manifold to permit parallel sampling for multiple compounds. To measure some contaminants that cannot be detected with a simple colorimetric tube, enhancements are available such as: • • • Colorimetric Direct-Reading Systems This category describes devices that rely on the color produced by the contaminant of interest and reagents in the sampling system to indicate airborne concentration.

A “pre-cleanse” tube before the detector tube removes interferences from the air sample so the contaminant of interest can be measured accurately. A “pyrolyzer” unit that uses heat to convert the contaminant to a compound that can be measured with the detector tube. A “trap” tube after the detector tube for long-term samples collected with a battery-powered pump to remove reaction products that could damage the pump. qxd 7/19/04 6:23 PM Page 30 30 AIR MONITORING OVERVIEW develops in the tube, although some devices use an internal photometer to read and display the colorimetric change.

In the spore stage the organism is encapsulated, is somewhat indifferent to temperature, and often behaves as a particle, whereas in the growth stage it can assume many different appearances but generally must be collected on some type of growth medium. Organic dusts, derived from vegetable, soil or animal sources, can have the characteristics of both chemical and microbial agents. Examples include grain dusts (oats, wheat, barley), straw, hay, wood dusts (a wide variety of compounds with many diverse effects ranging from asthma to suspect carcinogens), cotton, sewage sludge, and animal dander.
