Diuron is categorized as a probable human carcinogen by the United States Environmental Protection Agency (EPA). This work aimed to determine optimal conditions for catalytic degradation of in an aqueous solution with H2O2 using Algerian sodium Montmorillonite (Mont-Na) catalyst. The material characterized before and after experiment X-ray diffraction, Fourier transform infrared (FTIR) spectros...

Biochar amendment can alter soil properties, for instance, the ability to adsorb and degrade different chemicals. However, ageing of the biochar, due to processes occurring in the soil over time, can influence such biochar-mediated effects. This study examined how biochar affected adsorption and degradation of two herbicides, glyphosate (N-(phosphonomethyl)-glycine) and diuron (3-(3,4-dichlorop...

The objective of this work was to evaluate the acute toxicity commercial herbicides Karmex® (diuron: DCMU 3-(3,4-dichlorophenyl)-1,1-dimethylurea) and Herbipol® (glyphosate: N-(phosphonomethyl) glycine) on megalopae Callinectes sapidus measure their relative abundance in association larval postlarval species crustaceans from estuary Jamapa River, Veracruz. Collections were made overnight using ...

Herbicide selectivity is the basis for chemical control of weeds; however, it depends on interactions between herbicide, crop, and edaphoclimatic conditions. The objective this work was to evaluate herbicides applied at pre-emergence stage soybean cultivars with different maturation times grown in locations. experiment conducted under field conditions, two crop seasons (2019/2020 2020/2021), La...

BACKGROUND A recent Commentary article entitled "On the pathways feeding the H2 production process in nutrient-replete, hypoxic conditions" by Dr. Scoma and Dr. Tóth, Biotechnology for Biofuels (2017), opened a very interesting debate about the H2 production photosynthetic-linked pathways occurring in Chlamydomonas cultures grown in acetate-containing media and incubated under hypoxia/anoxia co...

Fungi have been recently recognized as organisms able to grow in presence of high salt concentration with halophilic and halotolerance properties and their ligninolytic enzyme complex have an unspecific action enabling their use to degradation of a number of xenobiotic compounds. In this work, both the effect of salt and polyols on growth of the basidiomycetes strains, on their ability to produ...

Off-line solid-phase extraction (SPE) combined with liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS-MS) was used to study the estuarine behaviour of the polar pesticides, atrazine, chloridazon, diuron and metolachlor, and their transformation products (TPs), hydroxyatrazine (HA), desisopropylatrazine (DIA), desethylatrazine (DEA), 3,4-dichlorophenylmethylurea (DPMU) and m...
