Carrier effect of S-metolachlor by microplastics and environmental risk assessment

Journal of Water Process Engineering, 2021
Abstract Organic pesticide pollutants have obvious negative effects on organisms in the environment. As an emerging organic contaminant, the ubiquitous microplastics (MPs) are undoubtedly regarded as the focus of global attention. MPs originate from the fragmentation of large plastic waste or direct environmental emissions. This research explored the

Adsorption of the herbicide S-Metolachlor on periodic mesoporous organosilicas

Chemical Engineering Journal, 2013
Abstract Due to their hydrophobic pore systems and high surface areas, periodic mesoporous organosilicas (PMOs) offer unique properties for use as adsorbents of organic compounds. Two organosilicas (ethane-PMO and benzene-PMO) and a silica (PMS) were synthesized following a similar procedure.

Metolachlor, S-metolachlor and their role within sustainable weed-management

Crop Protection, 1998
Abstract The herbicide metolachlor has been widely used for over 20 years for selective weed control in more than 70 crops worldwide. Its favourable soil behaviour and low risk for developing weed resistance means that metolachlor integrates well into sustainable weed-management practices, such as conservation tillage.

Effect of s-metolachlor application timing on cabbage tolerance

Crop Protection, 2007
There is limited information on the effect of s-metolachlor application timing on cabbage tolerance in Ontario. A total of five field trials (1999–2004) were established near Ridgetown Ontario, Canada to evaluate tolerance of cabbage to s-metolachlor applied pretransplant incorporated, pre-transplant and post-transplant at 800, 1600 and 2400 g a.i./ha.

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.

Endocrine and physiological effects of linuron and S-metolachlor in zebrafish developing embryos

Science of The Total Environment, 2017
Evaluation of the effects of linuron and S-metolachlor on apical, biochemical and transcriptional endpoints in zebrafish (Danio rerio) early life stages was the main purpose of this work. Embryos were exposed for 96h to a range of concentrations of each herbicide to determine lethal and sub-lethal effects on apical (e.g.

[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 ...

[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.

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.
