the continuous addition of industrial, municipal, and agricultural effluents to the environment has led to a great increase of toxic pollutants. it is well known that these pollutants are hazardous to animals, plants, microorganisms, and other living organisms including humans. as a result, effective technologies should be developed to remove these contaminants. biological remediation, as an...

The interaction between four industrial wine yeast strains and grape juice chemical contaminants during alcoholic fermentation was studied. Industrial strains of Saccharomyces cerevisiae (AWRI 0838), S. cerevisiae mutant with low H2S production phenotype (AWRI 1640), interspecies hybrid of S. cerevisiae and S. kudriavzevii (AWRI 1539) and a hybrid of AWRI 1640 and AWRI 1539 (AWRI 1810) were exp...

The impact of unmonitored contaminants, also known as contaminants of emerging concern (CECs), on freshwater streams remains largely uncharacterized. Water samples from 31 streams representing urban, agricultural and undeveloped (i.e., open space) land use in Southern California (USA) were analyzed for in vitro and in vivo bioactivity. The extent and magnitude of bioactivity screened using endo...

Recent studies have shown that dissolved organic matter (DOM) may inhibit the excited triplet-induced oxidation of several aromatic water contaminants, in particular those containing an aniline functionality. Such an inhibition was ascribed to antioxidant moieties of DOM. The present study was conducted with the aim of verifying whether well-defined antioxidants could act as inhibitors in analo...

The hydrogen peroxide treatment was able to remediate chlorophenols, polycyclic aromatic hydrocarbons, diesel and transformer oil contaminated soil. Chemical treatment of contaminants adsorbed in peat resulted in lower contaminants’ removal and required higher addition of chemicals than the treatment of contaminants in sand. The hydrogen peroxide treatment was found to be feasible for soil reme...

removal of typical contaminants like aromatic amines (e.g. 1-naphthalen amine, diphenyl amine, aniline, 2 and 6-dimethyl pyridine) from water during one-stage process is a method to purify water wherein organic contaminants get extracted from water by bentonite. in this study the effects of ph, stirring time, stirring speed, bentonite mass and bentonite size (mesh) were investigated. also, the ...

Accurately measuring the bioavailability of organic contaminants associated with complex environmental matrices is necessary for assessing contaminant risk, as well as for evaluating the effectiveness of proposed and in-place remediation strategies. Due to its importance, the bioavailability of organic contaminants associated with soils and sediments has been widely examined at the macroscopic ...

1. Many chemical contaminants are formed during the combustion of fuel both in the smoking and in the direct drying process. Examples include polycyclic aromatic hydrocarbons (PAH), dioxins, formaldehyde, nitrogen and sulphur oxides (relevant for formation of e.g. nitrosamines). Furthermore, heavy metals are also found in combustion gases. The types and amount of contaminants depend on the fuel...
