      <subfield code="a">The results of this study suggest that exposure to styrene below the current Swedish permissible exposure limit of 20ppm induces neurotoxic effects expressed as an increased number of neuropsychiatric symptoms. Twenty men exposed to styrene at a plastics factory participated. The reference group included 20 non-exposed men matched for age, working schedule, and physical work load</subfield>
