“…Substrates with the highest % of SMS such as SMS/straw/soil (50:25:25) and SMS/soil (50:50) showed the highest dissipation potential for all pesticides tested. In particular, the DT50s obtained for TBZ and IMZ in those organic biomixtures were amongst the lowest ever reported verifying their enhanced dissipation efficiency (Kesavan et al, 1976;Kreuzig et al, 2010;Omirou et al, 2012). Our findings are in accordance with the positive correlation between % of SMS in biobed substrates and pesticide biodegradation observed by Karanasios et al (2010a).…”

“…The long persistence of both IMZ (US EPA, 2003;Kreuzig et al, 2010) and TBZ (Kesavan et al, 1976;EC, 2013) in soil is well documented. Regarding organic biomixtures, our results are in agreement with Omirou et al (2012) who identified OPP and IMZ as the least persistent and the most persistent chemicals respectively, in different organic biomixtures derived from by-products of the winery and olive oil agro-industries compared to our SMS-rich biomixtures.…”

“…Only a few studies have investigated the dissipation of IMZ, TBZ and OPP in soil (Kreuzig et al, 2010;Kesavan et al, 1976), municipal wastewater treatment plants Korner et al, 2000) and organic substrates (Omirou et al, 2012), while even less are known regarding DPA. In sewage sludge Gardner et al (1982) reported the metabolism of DPA to aniline, 4-hydroxy-DPA and indole.…”

“…Omirou et al (2012) provided first evidence for the potential use of modified biobed systems for the depuration of wastewaters from the fruit-packaging industry. Such modified systems should be packed with organic materials which ensure effective dissipation of the particularly persistent (TBZ (EC, 2013) and IMZ (Kreuzig et al, 2010)) and toxic pesticides (OPP (EFSA, 2008), EQ (EFSA, 2010b) and DPA (EFSA, 2012)) contained in those agro-industrial effluents. The optimum composition of biobed packing material includes a lignocellulosic material like straw, soil and a humified substrate like peat or compost (Castillo et al, 2008).…”

“…The pesticides studied showed marked differences in their soil dissipation. TBZ and IMZ showed moderate to high persistence (Table 1) in accordance with previous reports which showed DT 50 of 41 to 135 days for IMZ (36,37), and 37 to 1100 days for TBZ (38,39). OPP, DPA, and EQ dissipated rapidly (DT 50 s Ͻ 2.2 days) in line with previous studies (4,24).…”

c Thiabendazole (TBZ), imazalil (IMZ), ortho-phenylphenol (OPP), diphenylamine (DPA), and ethoxyquin (EQ) are used in fruitpackaging plants (FPP) with the stipulation that wastewaters produced by their application would be depurated on site. However, no such treatment systems are currently in place, leading FPP to dispose of their effluents in agricultural land. We investigated the dissipation of those pesticides and their impact on soil microbes known to have a key role on ecosystem functioning. OPP and DPA showed limited persistence (50% dissipation time [DT 50 ], 0.6 and 1.3 days) compared to TBZ and IMZ (DT 50 , 47.0 and 150.8 days). EQ was rapidly transformed to the short-lived quinone imine (QI) (major metabolite) and the more persistent 2,4-dimethyl-6-ethoxyquinoline (EQNL) (minor metabolite). EQ and OPP exerted significant inhibition of potential nitrification, with the effect of the former being more persistent. This was not reflected in the abundance (determined by quantitative PCR [qPCR]) of the amoA gene of ammonia-oxidizing bacteria (AOB) and archaea (AOA). Considering the above discrepancy and the metabolic pattern of EQ, we further investigated the hypothesis that its metabolites and not only EQ were toxic to ammonia oxidizers. Potential nitrification, amoA gene abundance, and amoA gene transcripts of AOB and AOA showed that QI was probably responsible for the inhibition of nitrification. Our findings have serious ecological and practical implications for soil productivity and N conservation in agriculturally impacted ecosystems and stress the need to include metabolites and RNAbased methods when the soil microbial toxicity of pesticides is assessed. During postharvest handling, fruits are subjected to treatments with fungicides like thiabendazole (TBZ), imazalil (IMZ), and ortho-phenyl phenol (OPP) (1, 2) and antioxidants like diphenylamine (DPA) and ethoxyquin (EQ) (3), resulting in the production of large volumes of pesticide-contaminated wastewaters. The direct environmental discharge of those effluents without prior depuration entails a serious risk for the integrity of receiving ecosystems, considering the high aquatic toxicity of the pesticides (4, 5). This concern has been addressed by the European Commission (EC), and authorization for those pesticides was given with the stipulation "that an efficient treatment of the produced wastewaters should be operative at a local scale" (6, 7).Various processes and systems have been tested for the treatment of wastewaters produced by fruit-packaging plants (FPP) including adsorption onto activated carbon (8), photocatalytic degradation (9, 10), and biological degradation (11, 12). However, their high cost, their elevated technological requirements, and the frequent production of oxidized metabolites which are of unknown toxicity compared to the parent compound have hampered their full-scale implementation. Thus, to date effluents from FPP are either discharged in municipal wastewater treatment systems or they are disposed via land-spreading on the s...
