Job (activity&exposure profiles may be developed
in order to specify specific activities according
to their (estimated) similar level of exposure
rate (homogeneous exposure groups). The similarity
may be found at the level of the job (activity),
the task or the chemical [13,14]. This approach,
however, requires measurements and estimation
of the boundaries and it may depend on
the chemicals of concern. For some mixtures of
chemicals it may be possible to measure only a
suitable marker as a surrogate for the mixture
ml.
