A novel report of metallothioneins in fish bile: SDS-PAGE analysis, spectrophotometry quantification and metal speciation characterization by liquid chromatography coupled to ICP-MS.
Metallothioneins (MT) are a validated biomarker for metal exposure. In fish they are usually determined in the liver, while some studies have observed MT in kidney, muscle and gills. There are,Expand

Photocatalytic decomposition of seawater-soluble crude-oil fractions using high surface area colloid nanoparticles of TiO2
Abstract Photocatalytic destruction of the water-soluble crude oil fraction, WSF, was conducted using TiO2/UV–VIS. Infrared studies were carried out to investigate the transformations of crude oilExpand
