McElvenny DM, et al. - This study aims at investigating whether risk of meningioma is associated with several occupational exposures, including selected combustion products, dusts and other chemical agents. Excess risks of meningioma are not evident with most agents. Findings reveal a statistical association between exposure to oil mists and meningioma. This may be a chance finding or could be due to confounding with iron exposure and further research is needed to assess whether the relationship is causal.
