Asphalt workers rubber, aluminum, iron, steel, and tire factory workers and people working in the coke-producing industries are also at risk for potential exposure to coal tar pitch and coal tar pitch volatiles. They may breathe in vapors from or have direct skin contact with wood-preservation solutions, freshly treated wood, asphalt mixtures, or other products of coke-producing industries. Workers who use creosote-treated wood in building fences, bridges, or railroad tracks or installing telephone poles may be exposed those who inspect or maintain these materials, or apply asphalt or other coal tar pitch-containing materials, may also be exposed. Homeowners, farmers, or landscapers who apply coal tar creosote to wood in noncommercial... 

The best data available for the effects on man are coming from studies performed in different occupational environments (coke and gas workers, iron and steel workers, aluminium plants, carbon black industry and asphalt workers, etc. ..) a good review has been proposed by G. Lindstedt and J. Soelenberg in Search J. Environmental Health 8 (1982) 1-19. Although some criticism can be expressed on the referred substance and the analytical technique they have chosen.

Attempts have also been made to carry out surface modifications of the aggregate to enhance interactions with the asphalt (135) and other workers have made attempts to measure or predict the strength and type of asphalt—aggregate bonds (136,137). However, it must also be remembered that mix design parameters play an important role in determining the performance of asphalt—aggregate mixes (138—142). 

A few studies have reported an association between bladder and renal cancers and occupations having the potential for exposures to asphalt. In an historical cohort study of 1320 workers in the asphalt industry, there was a significant increase in brain cancer [standardized mortality ratio (SMR) 500] but not in respiratory, bladder, or gastrointestinal cancer. Of 679 Danish men who were heavily exposed to asphalt, significant increases occurred in the incidences of cancer of the mouth (SMR 1111), esophagus (698), rectum (318), and lung (344). ... 

NIOSH has determined that some workers exposed to asphalt fume are at an elevated risk for lung cancer however, it is uncertain whether this excess is related to asphalt or other carcinogens in the workplace. ...

The current sulfur-asphalt technologies are the result of research and development carried out since the late 1960 s, but the sulfur-asphalt concept is far from new. The foundation was laid in the 1930 s by Bencowitz 9) and his co-workers who produced and patented sulfur-asphalt mixtures which had several advantages over regular asphalt. 

Asphalt fumes are complex mixtures containing numerous organic compounds, PAHs and nitrogen, sulfur and oxygen-containing PAHs in vapor and aerosol form. Asphalt road pavers and highway maintenance workers are exposed to asphalt fumes by both inhalation and skin contact.
