Air sampling rates

Figure 3.10 Experimental air sampling rates as a function of log Koa for PCBs—open circles Ockenden etal. (1998), diamond Petty etal. (1993), closed circles Huckinsetal. (1994), closed triangles Shoeib and Harner (2002) polychlorinated naphthalenes—open triangles Shoeib and Harner (2002) PAHs—closed squares Robertson (2004) and pesticides—open squares Robertson (2004).

Verify the air sample rate, time, and location of the plate before starting the sampling. Sampling time should be 20 min at every location. After the sampling is complete, remove the collection plates, cover, and identify them. Identification should include date, sampling instrument number, location, and plate number.
