The purpose of this paper is 3-fold: a) to review briefly the neuropsychological tests that have been used to evaluate the effects of neurotoxicants; b) to identify individual factors that may create heightened sensitivity to neurotoxicants; and c) to discuss test parameters that will increase the sensitivity of neuropsychological tests for detecting symptoms in low-level exposure situations. W...

We examined the prevalence of multiple chemical sensitivities (MCS), a hypersensitivity to common chemical substances. We used a randomly selected sample of 1582 respondents from the Atlanta, Ga, standard metropolitan statistical area. We found that 12.6% of our sample reported the hypersensitivity and that, while the hypersensitivity is more common in women, it is experienced by both men and w...

Technological progress and related social processes will determine the measuring strategies of workplace air monitoring for the nineties even if the objective is dose estimation or compliance. Expectations of the lowest possible exposure, require workplace air monitoring to be closely linked to process control in a life cycle approach. Production regularity and preventive maintenance also becom...

Skepticism about the validity of the multiple chemical sensitivity (MCS) syndrome stems in part from the lack of supporting experimental data. Performing the relevant experiments requires investigators to take account of broad variations in sensitivity and the need to establish reproducibility. The research approach best suited for MCS studies is the single-subject design. In contrast with conv...
