Standard Practice for
Sampling and Selection of Analytical Techniques for
Pesticides and Polychlorinated Biphenyls in Air1

This standard is issued under the fixed designation D 4861; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope

1.1 This practice covers the sampling of atmospheres for a
variety of common pesticides and polychlorinated biphenyls
(PCBs) and provides guidance on the selection of appropriate
analytical measurement methods.

1.2 A complete listing of pesticides and other semivolatile
organic chemicals for which this practice has been tested is
shown in Table 1.

1.3 This practice is based on the adsorption of chemicals
from the air on polyurethane foam (PUF) or a combination of PUF
and granular sorbent.

1.4 This practice is applicable to multicomponent atmospheres, 0.001 to 50-µg/m3 concentrations, and 4 to 24-h
sampling periods. The limit of detection will depend on the
nature of the analyte and the length of the sampling period.

1.5 The analytical method(s) recommended will depend on
the specific chemical(s) sought, the concentration level, and the
degree of specificity required.

1.6 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard
statements, see 10.24 and A1.1.
