Salmonella assay - Opis:
- The paper presents the effect of UV radiation of 254 nmwavelength on the mutagenic activity of aquatic solutions of 3-chlorophenol (3-CP), 2,4-dichlorophenol (PCP), 2,4,6-trichlorophenol (2,4,6-TCP) and pentachlorophenol (PCP). Mutagenicity studies were carried out on two Salmonella strains: TA98 and TA100, with and without metabolic activation by S9 mix. Stable intermediate products of photodegradation have been identified using the GC/MS method. Chlorophenols in doses below 0.1µg were strongly mutagenic towards both strains: TA98 and TA100. The mutagenic properties of aquatic solutions of chlorophenols for both strains decreased as follows: PCP>=2,4-DCP>2,4,6-TCP>3-CP. Aquatic solutions of three chlorophenols after their photodegradation were non-mutagenic for both bacterial strains, except for 2,4-dichlorophenol. In the case of this compound, the products of its decomposition were more mutagenic for the TA100 strain. No significant metabolic activation by S9 mix was observed which suggests a direct mutagenic impact of chlorophenols on the tested Salmonella strains.
