“…In this investigation we have shown that halophilic bacteria are able to grow in the presence of DDVP and possibly metabolize the pollutant by mechanisms previously described by Lieberman & Alexander [8]. To our knowledge, this is the first study on the possible use of halophilic bacteria as decontamination agents of DDVP from the polluted saline water.…”

“…Since the mutagenicity of DDVP was suspected in Salmonella species [2], some studies have been done on the degradation of this compound in the photochemical treatment [3,4] and in the soil by some soil microorganisms [5][6][7]. It has been shown that DDVP is decomposed to dimethylphosphate and dichloroacetaldehyde and subsequently broken down into dichloroacetic acid, 2,2-dichloroethanol, and ethyl dichloroacetate [8]. DDVP is highly toxic by inhalation, dermal absorption and ingestion [9,10].…”

“…The degradation is more rapid in alkaline pH (Lamoteaux, 1978) and high temperature (Faust, 1996). A study by Lartiges and Garrigues (Lieberman & Alexander, 1983) investigated the degradation of dichlorvos in different types of water under different environmental conditions. The study reported that in winter temperature, dichlorvos was still present in filtered water (pH 6.1) after 180 days; residues in river water (pH 7.3) and filtered river water (pH 7.3) disappeared after 81 days; residues in sea water (pH 8.1) disappeared after 34 days.…”

“…Microorganisms found in sewage sludges apparently can degrade dichlorvos which may require acclimation. However, the rate of degradation is slower than abiotic degradation (Lieberman & Alexander, 1983).…”

“…Once the level of dichlorvos in raw waters does not meet regulations, additional treatment processes have to be applied to comply with the drinking water standards. Treatment methods such as biodegradation (Lieberman and Alexander, 1983), ultrasonication (Schramm and Hua, 2001), adsorption (Lu et al, 1996), photocatalysis (Lu et al, 1993;Evgenidou et al, 2005Evgenidou et al, , 2006, and oxidation with Fenton's reagent and permanganate (Lu et al, 1997(Lu et al, , 1999Waldemer and Tratnyek, 2006) have shown effectiveness on the decomposition of dichlorvos. Among the above various treatment methods, permanganate oxidation is commonly used at water treatment plants due to the stability, ease of handling, wide pH range, and low cost of the oxidant.…”
