background: the presence of pesticide due to the huge demand for agricultural purposes is very prevalent in surface waters of iran. these pesticides could finally accumulate in aquatic ecosystems and have been proved to have toxic effects on aquatic animals. the aim of this study was to assess the acute toxicity of diazinon, deltamethrin, butachlor and pretilachlor on zebra cichlid (cryptoheros...

The pollution of surface water by recently used pesticides in Mekong Delta, a main drinking water source, is increasing both on the concentration residues and the polluted area [1,2]. Nanofiltration (NF) is arising as the most appropriate method for removal of pesticides with not only a good efficiency but also low energy consumption in comparison with other pressure-driven membrane processes [...

Abstract Background The chloroacetamide herbicides pretilachlor is an emerging pollutant. Due to the large amount of use, its presence in environment threatens human health. However, molecular mechanism degradation remains unknown. Results Now, Rhodococcus sp. B2 was isolated from rice field and shown degrade pretilachlor. maximum efficiency (86.1%) observed at a culture time 5 d, initial subst...

A dynamic aquatic model (DynA model) was previously developed to predict the fate of a chemical in aquatic scenarios characterized by daily or periodic changes in several input parameters. DynA model is here calibrated with data obtained from the literature in specific unsteady state scenarios, such as those of rice fields. The results obtained for two herbicides (cinosulfuron and pretilachlor)...

Ischaemum rugosum Salisb. (Saramolla grass) is a noxious weed of rice that is difficult to control by chemical or mechanical means once established. A study was conducted to determine the effect of light, temperature, salt, drought, flooding, rice residue mulch, burial depth, and pre-emergence herbicides on seed germination and emergence of I. rugosum. Germination was stimulated by light and in...

Pregnane X receptor (PXR, NR1I2) is activated by various chemically unrelated compounds, including environmental pollutants and drugs. We proceeded here to in vitro screening of 28 pesticides with a new reporter system that detects human pregnane X receptor (hPXR) activators. The cell line was obtained by a two-step stable transfection of cervical cancer HeLa cells. The first transfected cell l...
