Mutagenicity assessment of produced water during photoelectrocatalytic degradation.
Oilfield produced water was treated by photocatalysis, electro-oxidation, and photoelectrocatalysis, respectively. The chemical composition and toxicity of the raw effluent and treated products were assessed by chemical and mutagenicity analysis. The raw effluent exhibited mutagenic activity in both strains of Salmonella typhimurium. The lowest concentration of the dichloromethane extract capab...
متن کاملMutagenicity of the drinking water supply in Bangkok.
Seventeen samples of tap water in Bangkok and 2 neighboring provinces were collected in winter and summer, concentrated and tested for mutagenic activity using the Ames Salmonella mutagenesis assay. Preliminary results demonstrated that concentrated tap water exhibited clear mutagenicity towards S. typhimurium TA100 and YG1029, but not towards TA98 and YG1024, in the absence of S9 mix, and the ...

Ames Mutagenicity Assessment of Flavored Water Pipe Tobacco Products :A Cross Sectional Study in Tehran
Waterpipe smoking has become a global youth trend especially in the Middle East countries and Iran . The aim of this study was to determine the mutagenic effects of three most popular flavored tobaccos by four different salmonella typhimurium strains and compare the possible mutagenic effects of the test samples. Ames mutagenicity assessment was conducted according to the OECD guideline using T...
متن کاملMutagenicity and anti-mutagenicity of selected spices.
Using Salmonella typhimurium strains TA 100 and TA 1535, the mutagenicity and anti-mutagenicity of extracts of several spices were checked. Spices like pepper, pippali, ginger and mustard increased the number of revertants indicating their mutagenic potential. Garlic extract on the other hand was found to inhibit the mutagenicity produced by direct acting mutagens such as N-methyl N'-nitro-N-ni...
