NATURE AND NURTURE LESSONS FROM CHEMICAL CARCINOGENESIS

Boyland and Levi proposed in 1935 that toxic PAHs might either be intravitally converted into more active pathogenic substances or detoxified 75.

Rehn, that cancer of the bladder was more common in workers at a dyestuffs factory than in the general population and his suggestion that these tumours had an occupational origin.

The majority of outdoor PAHs are derived from coal tar, die-sel exhausts and cigarette smoke.[5] In addition to inhalation, dermal exposure to PAHs represents an important route as they can be easily absorbed through the skin.[2] Numerous studies support the associa-tion between PAHs and adverse effects on skin health.
