The structure of the copper complex of the 6-((1-butanethiol)oxy)-tris(2-pyridylmethyl)amine ligand (Cu-tmpa-O(CH2)4SH) anchored to a gold surface has been investigated. To enable covalent attachment of the complex to the gold surface, a heteromolecular self-assembled monolayer (SAM) of butanethiol and a thiol-substituted

Indicators of free-radical or oxidant-mediated responses were quantified in channel catfish, Ictalurus punctatus, exposed to the organophosphorus herbicide DEF and its metabolite, n-butyl mercaptan (nBM). The activities of the antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase did
