Mutagenicity assays were carried out in the Salmonella/microsome test, using five S. typhimurium his(-) strains (TA1535, TA1537, TA1538, TA98 and TA100), both in the presence and absence of post-mitochondrial preparations from Aroclor-induced rat liv

Investigations were carried out in a coastal area of the Tyrrhenian Sea, which receives wastes from a chemical manufacturing industry. Industrial wastes are combined with domestic sewage prior to discharge into the sea. Warm and alkaline wastewaters

Various mechanisms tend to reduce hexavalent chromium (Cr(VI)) in the organism, both outside and inside target cells. A reducing activity has been demonstrated in the blood (mainly in erythrocytes), in secretions of the alimentary tract (saliva, gast

Hexavalent chromium compounds (sodium dichromate, potassium chromate, chromic acid, basic zinc chromate and basic lead chromate) were found to be mutagenic for his − strains of S. typhimurium by inducing both frameshifts and base-pair substitutions

Four hexavalent and two trivalent chromium compounds were tested for toxicity and mutagenicity by means of the Salmonella typhimurium /mammalian-microsome test. All hexavalent compounds yielded a complete inhibition of bacterial growth at doses of 40

Soluble trivalent chromium compounds (chromium potassium sulfate, chromium nitrate, chromium chloride, neochromium and chromium alum) were inactive for Salmonella typhimurium TA100, even at milligram amounts per plate. No effect could be detected eit

Pulmonary alveolar macrophages (PAM), obtained by bronchoalveolar lavage from 47 individuals, reduced hexavalent chromium [Cr(VI)] and decreased its mutagenicity. Their specific activity--mostly mediated by cytosolic, enzyme-catalyzed mechanisms--was
This paper reports the results of a 4-year investigation, concerning the microbiological quality of coastal waters in the Tyrrhenian Sea, for a total coastline length of approximately 180 km. The monitored areas include the Tuscany littoral in the di
