NMAM is a collection of methods for sampling
and analysis of contaminants in workplace air, and in the blood and urine
of workers who are occupationally exposed. These methods have been developed
or adapted by NIOSH or its partners and have been evaluated according
to established experimental protocols and
performance criteria. NMAM also includes chapters on quality assurance,
sampling, portable instrumentation, etc.
Individual
analytical methods are in Adobe Acrobat format and require the free

NIOSH recommends that the best method available be used for making each
measurement. Methods published by others, such as OSHA,
MSHA, EPA,
ASTM, ISO
or commercial suppliers of sampling and analytical equipment, may have
advantages over NIOSH methods for a given sampling situation. (An Industrial
Hygienist should determine the sampling protocol, considering analytical
accuracy, cost, and optimum sample number.) Every method should undergo
an initial evaluation to demonstrate performance. When a method is used
in a laboratory that did not perform the initial evaluation, that laboratory
should verify that comparable results can be obtained. NIOSH methods may
need to be modified, and if modified, should be re-evaluated. Various
OSHA regulations (e.g. benzene)
mention performance criteria for evaluating whatever method is used.
NIOSH has published methods developed in cooperating laboratories. These
method performance have been evaluated using established experimental
protocols. These methods were selected based upon priorities established
in a joint NIOSH/AIHA survey of participating laboratories.
