Solar photocatalytic treatment of trimethoprim in four environmental matrices at a pilot scale: Transformation products and ecotoxicity evaluation. The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online. Photoproducts characterization and formation of light induced secondary OH precursors (LIS-OH). Therefore, their reaction with oxidizing agents is quite different from that of primary or secondary alcohols. Since evidence for both oxidative damage and the involvement for glutathione in the toxicity of butylated hydroxyanisole is available, this mechanism may be involved in the toxic action of this compound.
