Biodegradation of anthelmintics in soils: does prior exposure of soils to anthelmintics accelerate their dissipation?
(2022)Anthelmintics (AHs) control animal infections with gastrointestinal nematodes. They reach soil through animal faeces deposited on soils or through manuring. Although soil constitutes a major AH sink, we know little about ... -
Dissipation and adsorption of isoproturon, tebuconazole, chlorpyrifos and their main transformation products under laboratory and field conditions
(2016)Assessment of dissipation constitutes an integral part of pesticides risk assessment since it provides an estimate of the level and the duration of exposure of the terrestrial ecosystem to pesticides. Within the frame of ... -
The dissipation and microbial ecotoxicity of tebuconazole and its transformation products in soil under standard laboratory and simulated winter conditions
(2018)Tebuconazole (TBZ) is a widely used triazole fungicide at EU level on cereals and vines. It is relatively persistent in soil where it is transformed to various transformation products (TPs) which might be environmentally ... -
The dissipation of fipronil, chlorpyrifos, fosthiazate and ethoprophos in soils from potato monoculture areas: First evidence for the enhanced biodegradation of fosthiazate
(2016)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 teflubenzuron and triflumuron residues in field-sprayed and cold-stored pears
(1999)Dissipation of residues of benzoylurea insecticides teflubenzuron (TFB) and triflumuron (TFM) under field conditions was evaluated on a pear orchard in Greece. Residues were determined by UV-HPLC analysis, with a detection ... -
Field persistence studies on pendimethalin residues in onions and soil after herbicide postemergence application in onion cultivation
(1998)Field studies were undertaken to evaluate the fate of pendimethalin residues in spring and dry onions, after postemergence application of the herbicide in a clay soil onion planting in central Greece, at rates of 1.32 and ... -
Identification and characterization of tebuconazole transformation products in soil by combining suspect screening and molecular typology
(2016)Pesticides generate transformation products (TPs) when they are released into the environment. These TPs may be of ecotoxicological importance. Past studies have demonstrated how difficult it is to predict the occurrence ... -
Persistence of pendimethalin in cotton fields under sprinkler or drip irrigation in central Greece
(2004)The dissipation of pendimethalin was investigated in soils of cotton fields in Thessaly, central Greece, for a period of two years. The fields were irrigated either with sprinkler or with sprinkler for the first two ...
