These documents describe methods for sampling and analysis of a variety of common pesticides and for:

• polychlorinated biphenyls (PCBs) in ambient air. The high volume (method TO-4A) sampler procedure is based on the adsorption of chemicals from
• ambient air on polyurethane foam (PUF). The low volume (method TO-10A) procedure is based on the adsorption of chemicals from
• ambient air on polyurethane foam (PUF) or a combination of PUF and granular sorbent.
