This study evaluated the impact of pesticide application through agricultural activities in Chanchaga River, Nigeria, using macroinvertebrate data sets obtained for six months (September 2021–February 2022). Four (4) stations, characterized by various activities, were sampled along river. Analysis water samples organochlorine residues (OCP) Gas Chromatography-Mass Spectrometry (GC/MS) at peak two seasons revealed a high concentration eleven isomers organochlorine, which ranged from 0.01 to 0.81 μg/L, and mean that was above international drinking standards set World Health Organization, Federal Environmental Protection Agency, European Union.

The Patagonian steppe is a vast territory with diverse array of aquatic environments low fish richness, including several exotic species which are mostly salmonids. Unlike the Andean region, knowledge ichthyofauna and fisheries plateau comparatively scarce. characteristics their assemblages vary greatly in large basins that cross steppe. Fish north Patagonia include elements Patagonian, Cuyean, Pampean ichthyological provinces, where Austral Brazilic subregion overlap. Salmonid richness increases from northern to southern latitudes, as do anadromous species. also presents some endorheic inhabited by high conservation value restricted distribution.

Historical current management policies permitted uncontrolled stocking due fishing value, thus favoring reduction distribution abundance native fishes, endangered an extreme degree endemism.

Assessment of the impacts of GABA and AChE targeting pesticides on freshwater invertebrate family richness in English Rivers

The Science of The Total Environment, Journal Year: 2023, Volume and Issue: 912, P. 169079 - 169079

Published: Dec. 2, 2023

Globally, riverine system biodiversity is threatened by a range of stressors, spanning pollution, sedimentation, alterations to water flow, and climate change. Pesticides have been associated with population level impacts on freshwater invertebrates for acute high-level exposures, but far less known about the chronic impact episodic exposure specific classes pesticides or their mixtures. Here we employed use UK Environment Agency's monitoring datasets over 40 years (covering 1980 2019) assess AChE (acetylcholinesterase) GABA (gamma-aminobutyric acid) receptor targeting invertebrate family richness at English river sites. Concentrations toxic occurred (measured) across 18 66 sites assessed.

Chlorpyrifos removal: Nb/boron-doped diamond anode coupled with solid polymer electrolyte and ultrasound irradiation

Published: Oct. 9, 2020

Abstract Chlorpyrifos is an organophosphorus insecticide, acaricide and miticide used worldwide for the control of soil-borne insect pests. It must be considered as a substance growing concern, given its use, toxicity, environmental occurrence, potential regional to long-range atmospheric transport. Considering incomplete removal attained by conventional water treatment processes, we investigated efficiency electrolytic radicals production sonoelectrolysis on degradation pesticide. The has been conducted in novel electrochemical reactor, equipped with boron-doped diamond anode solid polymer electrolyte (SPE). Different current intensity times have tested coupled sonication at 40 kHz. Up 69% chlorpyrifos was completely removed 10 min electrolysis operated 0.1 mA, while 12.5% 5.4% converted into intermediates 3,5,6-trichloro-2-pyridinol (TCP) diethyl (3,5,6-trichloropyridin-2-yl) phosphate, respectively. Ultrasound irradiation did not enhance efficiency, likely due mass transport limitations, energy consumption increased from 8.68∙10 − 6 9.34∙10 4 kWh µg 1 removed.
