The oxidation of leachate coming from the composting of two organic wastes (wastewater sludge and organic fraction of municipal solid wastes) using the Fenton's reagent was studied using different ratios [Fe(2+)]/[COD](0) and maintaining a ratio [H(2)O(2)]/[COD](0) equal to 1. The optimal conditions for Fenton reaction were found at a ratio [Fe(2+)]/[COD](0) equal to 0.1. Both leachates were significantly oxidized under these conditions in terms of COD removal (77 and 75% for leachate from wastewater sludge composting and leachate from organic fraction of municipal solid wastes, respectively) and BOD(5) removal (90 and 98% for leachate from wastewater sludge composting and leachate from organic fraction of municipal solid wastes, respectively). Fenton's reagent was found to oxidize preferably biodegradable organic matter of leachate. In consequence, a decrease in the biodegradability of leachates was observed after Fenton treatment for both leachates. Nevertheless, Fenton reaction proved to be a feasible technique for the oxidation of the leachate under study, and it can be considered a suitable treatment for this type of wastewaters.

Mutagenicity analysis of water samples from Camalti Saltern, Turkey were investigated by applying Salmonella mutagenicity test. Plate incorporation assay was applied in the absence of metabolic activation. XAD 4 and XAD 16 columns were used for the fractionation of the water samples. The results obtained were negative in both TA 98 and TA 100. Although the number of revertants of XAD 16 extract in station B were higher than the revertants in the other stations for TA 98 strain when compared to the solvent control. However this was not significant to be considered as mutagenic. The results were discussed for the future analysis.

“…The catalysts of AC and TiO 2 / AC can accelerate the transformation of ozone with large amount of OH radicals generation. The OH radical is a very powerful and nonselective oxidizing agent which can deal with organic compounds until mineralized [23]. Organic molecules can be destroyed by OH radical at the high rate of 10 6 -10 9 M À1 s À1 [24].…”
