Analytica chimica acta, 843, 59-72 (2014-08-26)
Synchrotron-based Fourier transform infrared micro-spectroscopy (SR-μFTIR) was used to map photo-oxidative degradation of acrylonitrile-butadiene-styrene (ABS) and to investigate the presence and the migration of additives in historical samples from important Italian design objects. High resolution (3×3 μm(2)) molecular maps were

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

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)
Niall D O'Leary et al.
FEMS microbiology reviews, 26(4), 403-417 (2002-11-05)
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
