The last few decades have seen a steady increase in the global production and utilisation of the alkenylbenzene, styrene. The compound is of major importance in the petrochemical and polymer-processing industries, which can contribute to the pollution of natural resources

Beach sand and seawater taken from the coastlines of the North-East Pacific Ocean and Hawaii State were investigated to determine the causes of global chemical contamination from polystyrene (PS). All samples were found to contain styrene monomer (SM), styrene dimers (SD)

Styrene is an important industrial chemical that has shown genotoxicity in many toxicology assays. This is believed to be related to the DNA-binding properties of styrene-7,8-oxide (SO), a major metabolite of styrene. In this review, we have summarized knowledge on
James J Collins et al.
Epidemiology (Cambridge, Mass.), 24(2), 195-203 (2013-01-25)
Epidemiologic studies have reported increased risk of lymphohematopoietic cancers, lung cancer, and pancreatic cancer after exposure to styrene, although findings across studies are not consistent. We update a large study of reinforced plastic industry workers with relatively high exposures to
