Influence of River Water in the Detection of Cr(VI) Mutagenicity by the Ames Test

Toxicity and genotoxicity assessment in sediments from the Matanza-Riachuelo river basin (Argentina) under the influence of heavy metals and organic contaminants

“…Some trace metals are considered to be essential for living organisms, e.g. they facilitate electron transfer reactions, catalyze enzymatic reactions and take part in the structural functions of nucleic acid metabolism, but they may be toxic or mutagenic in excessive amounts (Borboa and La Torre, 1996;López et al, 1998;Fedorova et al, 2007;Nagajyoti et al, 2010). The comparison of methodologies for inorganic compound extraction in the present study identified the largest total concentration of metals in acidic extracts submitted to extraction by ultrasound, followed by acidic extracts prepared by shaking.…”
