Antibacterial drugs in products originating from aquaculture: assessing the risks to public welfare
(2010)As aquaculture expands to meet human demand and compensate for pessimistic forecasts of fisheries catches, use of antibacterial agents to combat or forestall bacterial diseases is still a necessity, although effective ... -
Application of single-drop microextraction coupled with gas chromatography for the determination of multiclass pesticides in vegetables with nitrogen phosphorus and electron capture detection
(2009)In the present work the single-drop microextraction (SDME) technique coupled with GC-NPD and GC-ECD was evaluated for the determination of multi-class pesticides in vegetables. The donor sample solution preparation was ... -
Comparison of spinosad with three traditional grain protectants against Prostephanus truncatus (Horn) and Ephestia kuehniella (Zeller) at different temperatures
(2013)The insecticidal effects of deltamethrin, chlorpyriphos-methyl, pirimiphos-methyl, and spinosad were evaluated against adults of Prostephanus truncatus (Horn) (Coleoptera: Bostrychidae) and larvae of Ephestia kuehniella ... -
Determination of benzoylurea insecticides in apples and pears by solid-phase extraction cleanup and liquid chromatography with UV detection
(1999)A liquid chromatographic (LC) method was developed and statistically validated for simultaneous determination of 5 benzoylurea insecticides (diflubenzuron, triflumuron, teflubenzuron, flufenoxuron, and lufenuron) in apples ... -
Development and validation of an HPLC-DAD method for the simultaneous determination of most common rice pesticides in paddy water systems
(2012)Rice crop is mainly cultivated in large river basins which constitute unique ecosystems and their ecological quality is invaluable. However, the high loads of pesticides used in rice cultivation contribute to the contamination ... -
The dissipation of three fungicides in a biobed organic substrate and their impact on the structure and activity of the microbial community
(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 ... -
Effects of Pea Cultivation as Cover Crop on Nitrogen-Use Efficiency and Nitrogen Uptake by Subsequent Maize and Sunflower Crops in a Sandy Soil in Central Greece
(2013)The long-term positive effects of cropping systems involving rotation with cover crops on soil properties and the environment are well recognized. The present work concerns a 3-year field experiment focusing on two cropping ... -
Experimental and modelling analysis of pesticide fate from greenhouses: The case of pyrimethanil on a tomato crop
(2012)The distribution of a pesticide on target and non-target elements of a greenhouse, and its fate after application, was studied. The experiments were performed in a round arched greenhouse with vertical side walls containing ... -
Headspace single-drop microextraction of common pesticide contaminants in honey-method development and comparison with other extraction methods
(2012)In the present study the main factors that may influence the headspace single-drop microextraction (HS-SDME) of common pesticide contaminants (diazinon, lindane, chlorpyrifos ethyl, p,p'-DDE, and endosulfan) that may occur ... -
Incubation experiments on net nitrogen mineralization in organic Greek soils
(2005)Aerobic incubation experiments were conducted in organic surface samples collected from arable soils of Philippoi, in Northern Greece. Laboratory experiments were carried out to investigate the nitrogen (N) mineralized ... -
Key parameters and practices controlling pesticide degradation efficiency of biobed substrates
(2012)We studied the contribution of each of the components of a compost-based biomixture (BX), commonly used in Europe, on pesticide degradation. The impact of other key parameters including pesticide dose, temperature and ... -
Laboratory and field dissipation of penoxsulam, tricyclazole and profoxydim in rice paddy systems
(2013)Rice cultivation relies on pesticide applications to ensure high yields. However, the regular use of pesticides seriously affects the quality of neighboring surface water systems. Thus complete knowledge of the environmental ... -
On-farm biopurification systems for the depuration of pesticide wastewaters: recent biotechnological advances and future perspectives
(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
(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 ... -
Poor bioavailability of oxytetracycline in sharpsnout sea bream Diplodus puntazzo
(2004)The pharmacokinetics of oxytetracycline (OTC) were investigated following single intravascular injection (40 mg/kg) in sharpsnout sea bream (90 g) at 19 degreesC. The distribution half-life (t(1/2alpha)) and the elimination ...
