Because the findings of in vivo and in vitro research so strongly implicate the involvement of ROS in benzene-induced toxicity (Snyder and Hedli 1996), we designed a study to investigate the carcinogenic mechanism of benzene, focusing on BT, a benzene metabolite that generates ROS by autoxidation (Kawanishi et al.

Working at the university's Australian Research Council (ARC) Centre of Excellence for Free Radical Chemistry and Biotechnology, the scientists dismissed assumptions that plastics left in the sun, such as clothing pegs, inevitably become brittle through autoxidation.
This method is based on the SOD-mediated increase in the rate of autoxidation of 5,6,6,6 a,1 1 b tetrahydro - 3,9,10 - trihydroxybenzo (c) fluorine (TTF) in aqueous alkaline solution to yield a chromophore with maximum absorbance at 525 nm.
Under these conditions a variety of degradation reactions can occur, such as autoxidation, thermal polymerization, thermal oxidation, isomerization, cyclization and hydrolysis (Predojevic, 2008), leading to less molecular weight compounds and therefore to a higher saponification value.
