[Mental health and the exposure to organic solvents in the workplace.].
Organic solvents, due to their chemical properties have a particular affinity with the nervous system, giving them the power to interfere with the functioning of an element. Case histories and epidemiological studies have shown a relationship between a long term exposure to certain solvents and the danger of neuropathies, encephalopathies and psychiatric troubles. This article's aim is to expose the problem of the deterioration of the well being of persons exposed to neurotoxic agents. A study was made in an explosives factory with workers who were exposed to ethylic ether or ethanol and a control of 74 workers who were not exposed. This is an exploratory study which mostly looks into the prevalence of symptoms that could result from a professional contact with theses neurotoxic agents. The results show that the exposed workers, compared to those who were not exposed, are afflicted with more prenarcotic symptoms at work : such as feelings of drunkeness and difficulties in articulating words. The workers also show more frequently general symptoms such as changes of mood, problems of fatigue, sleep, memory and concentration. The reported numbers of prenarcotic symptoms increase with the degree of exposure. The significance of these results on the mental health of the persons involved is studied.
