Variability in response of the nervous system (central, peripheral) to workplace chemicals.

Abstract

The contemporary way of studying responses of the nervous system to workplace chemicals is the epidemiological approach. That is, of course, the way to study causal relationships between certain chemicals and adverse or subclinical nervous effects. We accept that the exposed and nonexposed (control) groups contain some individuals who have positive signs or otherwise belong to those with slightly deviant test results, but we assume that those deviant subjects are evenly distributed in both groups and thus do not prevent us from finding true causal relationships.
