Tolerance and phytoremediation capacity of atrazine and S-metolachlor by two duckweeds

Environmental Science and Pollution Research
The phytotoxicity and removal of atrazine and S-metolachlor in sterile duckweed systems were estimated in this study. Herbicides were added at environmentally relevant ranges: 0-400 µg/L for atrazine or 0-200 µg/L for S-metolachlor in systems with Spirodela polyrhiza or Lemna minor.

[Influence of S-metolachlor and Cd2+ on photosynthesis of Scenedesmus obliquus].

Huan jing ke xue= Huanjing kexue, 2015
The single and combined effects of Cd2+ and S-metolachlor on the chlorophyll content and chlorophyll fluorescence parameters of Scenedesmus obliquus were studied by using standard toxic testing method. Both Cd2+ and S-metolachlor had effects on the chlorophyll content and fluorescence parameters such as F0, FV/Fm, FV/F0, Y( II), qP, NPQ and rETR after ...

[Toxicity effects of Rac- and S-metolachlor on two algaes].

Huan jing ke xue= Huanjing kexue, 2013
The enantioselective toxicity of the chiral herbicides Rac- and S-metolachlor to Scenedesmus obliquus and Chlorella vulgaris was determined, and the effect of humic acid was studied by using acute toxicity testing method. The results indicated that the toxicity of Rac- and S-metolachlor increased with increasing concentration and exposure time.

Ecotoxicity of nicosulfuron and S-metolachlor-based herbicides on non-target plants

Journal of Toxicology and Environmental Health, Part A
Herbicides have been extensively researched due to widespread use in agriculture, consequently raising concerns regarding their environmental impact and potential adverse effects on non-target organisms, including humans. Nicosulfuron is a post-emergence herbicide used to control annual or perennial grasses and broad-leaved weeds.

Toxicity mechanism of organosilicon adjuvant in combination with S-metolachlor on Vigna angularis

Journal of Hazardous Materials
The widespread use of S-metolachlor (ME) in agriculture to suppress weeds and boost crop yields, particularly in cultivating Vigna angularis, is well established. However, the application of organosilicon adjuvants with herbicides has potential threats to non-target crops. This study investigates the toxicity symptoms and mechanisms when V.

[Combined toxicity of cadmium and S-metolachlor to Scenedesmus obliquus].

Huan jing ke xue= Huanjing kexue, 2015
The single and combined effects of Cd2+ and S-metolachlor on acute toxicity, total soluble protein content, superoxide dismutase (SOD) activity and cell membrane permeability of Scenedesmus obliquus (S. obliquus) were studied using the standard toxic testing methods.

Bacterial communities in batch and continuous-flow wetlands treating the herbicide S-metolachlor

Science of The Total Environment, 2014
Knowledge of wetland bacterial communities in the context of pesticide contamination and hydrological regime is scarce. We investigated the bacterial composition in constructed wetlands receiving Mercantor Gold(®) contaminated water (960 g L(-1) of the herbicide S-metolachlor, >80% of the S-enantiomer) operated under continuous-flow or batch modes to ...
