Long term hazards

Styrene -— Classified by ACGIH (the American Conference of Governmental Industrial Hygienists) as category A4 (not classifiable as a human carcinogen). — Classified by IARC (the International Agency for Research on Cancer) as category 2B (possibly carcinogenic to humans). — Classified by NTP (the National Toxicology Program) in Group 2 (reasonably anticipated to be a human carcinogen). — An increased incidence of lung tumors was observed in mice from a recent inhalation study. The relevance of this finding is uncertain since data from other long-term animal studies and from epidemiology studies of workers exposed to styrene do not provide a basis to conclude that styrene is carcinogenic to humans.
