Bio-pesticides: Harmful or harmless to ammonia oxidizing microorganisms? The case of a Paecilomyces lilacinus-based nematicide
Rousidou, C.; Papadopoulou, E. S.; Kortsinidou, M.; Giannakou, I. O.; Singh, B. K.; Menkissoglu-Spiroudi, U.; Karpouzas, D. G. (2013)Bio-pesticides are considered as low-risk compounds, a belief mainly based on their natural origin rather than on experimental evidence. Thus there is a need to explore the ecotoxicity of bio-pesticides and mostly their ... -

However, the high loads of pesticides used in rice cultivation contribute to the contamination ... -
The dissipation of fipronil, chlorpyrifos, fosthiazate and ethoprophos in soils from potato monoculture areas: First evidence for the enhanced biodegradation of fosthiazate
Papadopoulou, E. S.; Lagos, S.; Spentza, F.; Vidiadakis, E.; Karas, P. A.; Klitsinaris, T.; Karpouzas, D. G. (2015)BACKGROUND: A limited number of pesticides are available for the control of soil pests in potato. This, together with the monoculture nature of potato cultivation, does not favour chemical rotation, increasing the risk of ... -
Dissipation of pure and broccoli-released glucosinolates in soil under high and low moisture content
Omirou, M.; Karpouzas, D. G.; Papadopoulou, K. K.; Ehaliotis, C. (2013)Glucosinolates (GSLs) are secondary metabolites found in Brassica species. Upon tissue disruption GSLs are hydrolyzed by myrosinase enzymes to isothiocyanates (ITCs) which are highly toxic to microbes. Therefore the ... -
The dissipation of three fungicides in a biobed organic substrate and their impact on the structure and activity of the microbial community
Marinozzi, M.; Coppola, L.; Monaci, E.; Karpouzas, D. G.; Papadopoulou, E.; Menkissoglu-Spiroudi, U.; Vischetti, C. (2013)Biopurification systems (BPS) have been introduced to minimise the risk for point source contamination of natural water resources by pesticides. Their depuration efficiency relies mostly on the high biodegradation of their ... -
Dissipation, metabolism and sorption of pesticides used in fruit-packaging plants: Towards an optimized depuration of their pesticide-contaminated agro-industrial effluents
Karas, P.; Metsoviti, A.; Zisis, V.; Ehaliotis, C.; Omirou, M.; Papadopoulou, E. S.; Menkissoglou-Spiroudi, U.; Manta, S.; Komiotis, D.; Karpouzas, D. G. (2015)Wastewaters from the fruit-packaging industry constitute a serious point source contamination with pesticides. In the absence of effective depuration methods, they are discharged in municipal wastewater treatment plants ... -
Do Botanical Pesticides Alter the Structure of the Soil Microbial Community?
Spyrou, I. M.; Karpouzas, D. G.; Menkissoglu-Spiroudi, U. (2009)The effects of synthetic pesticides on the soil microbial community have been thoroughly investigated in the past mostly by culture-dependent methods and only few recent studies have used culture-independent approaches for ... -
ECOFUN-MICROBIODIV: An FP7 European project for developing and evaluating innovative tools for assessing the impact of pesticides on soil functional microbial diversity-towards new pesticide registration regulation?
Martin-Laurent, F.; Kandeler, E.; Petric, I.; Djuric, S.; Karpouzas, D. G. (2013) -
Effect of continuous olive mill wastewater applications, in the presence and absence of nitrogen fertilization, on the structure of rhizosphere-soil fungal communities
Karpouzas, D. G.; Rousidou, C.; Papadopoulou, K. K.; Bekris, F.; Zervakis, G. I.; Singh, B. K.; Ehaliotis, C. (2009)Olive mill wastewater (OMW) is rich in potentially toxic organics precluding its disposal into water receptors. However, land application of diluted OMW may result in safe disposal and fertilization. In order to investigate ... -
