Microwave-assisted Extraction of Glucosinolates from Eruca sativa Seeds and Soil: Comparison with Existing Methods
Omirou, M.; Papastylianou, I.; Iori, R.; Papastephanou, C.; Papadopoulou, K. K.; Ehaliotis, C.; Karpouzas, D. G. (2009)Introduction - Glucosinolates (GSLs) are secondary plant metabolites that are abundant in brassicas and their hydrolysis products, isothiocyanates, are toxic to soil pathogens. Efficiency and extraction time are critical ... -
A multi-residue method for pesticide residue analysis in rice grains using matrix solid-phase dispersion extraction and high-performance liquid chromatography-diode array detection
Tsochatzis, E. D.; Menkissoglu-Spiroudi, U.; Karpouzas, D. G.; Tzimou-Tsitouridou, R. (2010)Pesticides are widely used in rice cultivation, often resulting in detection of their residues in rice grains. So far, no analytical method has been available for the simultaneous determination of most rice pesticides in ... -
Novel biomixtures based on local Mediterranean lignocellulosic materials: Evaluation for use in biobed systems
Karanasios, E.; Tsiropoulos, N. G.; Karpouzas, D. G.; Menkissoglu-Spiroudi, U. (2010)The composition of biomixtures strongly affect the efficacy of biobeds. Typically, biomixture consists of peat (or compost), straw (SIR) and topsoil (1:2:1 by volume). Straw guarantees a continuous supply of nutrients and ... -
Olive mill wastewater affects the structure of soil bacterial communities
Karpouzas, D. G.; Ntougias, S.; Iskidou, E.; Rousidou, C.; Papadopoulou, K. K.; Zervakis, G. I.; Ehaliotis, C. (2010)Land spreading of olive mill wastewater (OMW) has beets proposed as a useful means for its disposal. However, there is no information regarding the impact of OMW soil applications on the structure of bacterial communities. ... -
On-farm biopurification systems for the depuration of pesticide wastewaters: recent biotechnological advances and future perspectives
Karanasios, E.; Tsiropoulos, N. G.; Karpouzas, D. G. (2012)Point source contamination of natural water resources by pesticides constitutes a serious problem and on-farm biopurification systems (BPS) were introduced to resolve it. This paper reviews the processes and parameters ... -
Optimization of Biomixture Composition and Water Management for Maximum Pesticide Dissipation in Peat-Free Biobeds
Karanasios, E.; Papadi-Psyllou, A.; Karpouzas, D. G.; Tsiropoulos, N. G. (2012)Biomixture composition and water management are key factors controlling biobeds performance. Although compost-biomixtures (BXs) possess high degradation efficiency, their low water-holding capacity compared with peat-biomixtures ... -
Pesticide exposure assessment in rice paddies in Europe: a comparative study of existing mathematical models
Karpouzas, D. G.; Cervelli, S.; Watanabe, H.; Capri, E.; Ferrero, A. (2006)A comparative test was undertaken in order to identify the potential of existing mathematical models, including the rice water quality (RICEWQ) 1.6.4v model, the pesticide concentration in paddy field (PCPF-1) model and ... -
Potential for bioremediation of agro-industrial effluents with high loads of pesticides by selected fungi
Karas, P. A.; Perruchon, C.; Exarhou, K.; Ehaliotis, C.; Karpouzas, D. G. (2011)Wastewaters from the fruit packaging industry contain a high pesticide load and require treatment before their environmental discharge. We provide first evidence for the potential bioremediation of these wastewaters. Three ... -
Quantitative and qualitative differences in the metabolism of pesticides in biobed substrates and soil
Karanasios, E. C.; Tsiropoulos, N. G.; Karpouzas, D. G. (2013)Biobed substrates commonly exhibit high degradation capacity. However, degradation does not always lead to detoxification and information on the metabolic pathways of pesticides in biobeds is scarce. We studied the degradation ... -
Repeated application of diluted olive mill wastewater induces changes in the structure of the soil microbial community
Rousidou, C.; Papadopoulou, K.; Zervakis, G.; Singh, B. K.; Ehaliotis, C.; Karpouzas, D. G. (2010)Repeated application of diluted olive mill wastewater (OMW) is a common disposal method which allows the application of large amounts of OMW and improves the organic matter and nutrient status of Mediterranean soils. ... -
Simulation models of pesticide fate and transport in paddy environment for ecological risk assessment and management
Inao, K.; Watanabe, H.; Karpouzas, D. G.; Capri, E. (2008)Rice production is one of the major non-point sources of pesticide pollution in Japan. Monitoring of pesticide concentrations in river systems detected a number of herbicides commonly used in paddy fields, and these ... -
A tiered assessment approach based on standardized methods to estimate the impact of nicosulfuron on the abundance and function of the soil microbial community
Karpouzas, D. G.; Kandeler, E.; Bru, D.; Friedel, I.; Auer, Y.; Kramer, S.; Vasileiadis, S.; Petric, I.; Udikovic-Kolic, N.; Djuric, S.; Martin-Laurent, F. (2014)Pesticides impact soil microorganisms in various ways. Despite the pivotal role of the latter in ecosystem functioning, the assessment of pesticides soil microbial toxicity is lagging behind the recent methodological ...
