Acute toxicity evaluation of five herbicides: paraquat, 2,4-dichlorophenoxy acetic acid (2,4-D), trifluralin, glyphosite and atrazine in Luciobarbus esocinus fingerlings
Background: Evaluation of herbicide pollution in aquatic environments needs the great concern and the most important echo-pollutant effects of herbicides are related to their effects on non target aquatic organisms. Native fish can serve as a proper bio-indicator for evaluation of pollution on aquatic ecosystems. OBJECTIVES: To find environmentally friendly herbicides, in this study the acute ...
متن کاملMagnetic Solid Phase Extraction of Triazine Herbicides from Environmental Aquatic Media using Polyaniline/ Fe3O4 Nanocomposite
Polyaniline/Fe3 O4 magnetic nanoparticles were synthesized and employed as a sorbent for the magnetic solid phase extraction (MSPE) of seven triazine herbicides from environmental water samples. The properties of the prepared magnetic sorbent were characterized using field emission-scanning electron microscopy (FE-SEM), fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetome...
متن کاملAcute Toxicity of Herbicides on the Survival of Adult Shrimp, Artemia Franciscana
Background: Herbicides are widely used in agriculture to kill a large variety of unwanted weeds. However, the application in water ecosystems may pose harmful impacts on the health of aquatic organisms. We studied the acute toxicity of four major types of herbicides on the survival of adult shrimp, Artemia franciscana (AF). Methods: The brine shrimp, AF, was hatched from the commercially encys...
متن کاملRemoval of 2,4-dichlorophenoxyacetic acid and 4-chloro-2-methyl phenoxyacetic acid herbicides from aquatic environments by a novel polymer magnetic nanoparticles
Background and Objective: Increased use of pesticides and chemical fertilizers in agriculture in order to increase the productivity of fertile lands has led to pollution of water resources with a variety of pollutants, including herbicides. In this study, a new polymer magnetic nanoadsorbent named PV/S-g-3D-GO/N was synthesized and used to remove 2,4-D and MCPA herbicides from aquatic environme...
متن کاملComparative Sensitivity of Five Species of Macrophytes and Six Species of Algae to Atrazine, Metribuzin, Alachlor, and Metolachlor
This study determined the relative sensitivity of five species of aquatic macrophytes and six species of algae to four commonly used herbicides (atrazine, metribuzin, alachlor, and metolachlor). Toxicity tests consisted of 96-h (duckweed and algae) or 14-d (submerged macrophytes) static exposures. The triazine herbicides (atrazine and metribuzin) were significantly more toxic to aquatic plants ...
