Insight Into the Formation Paths of Methyl Bromide From Syringic Acid in Aqueous Bromide Solutions Under Simulated Sunlight Irradiation

Methyl bromide under fire.

Methyl Bromide under Fire Methyl bromide is one of the most widely used pesticides in the world, a broad-spectrum fumigant effective in controlling insects, nematodes, fungi, and bacteria. Methyl bromide is also highly toxic to humans. In December 1993, the EPA listed methyl bromide as a stratospheric ozone-depleting substance subject to phase-out. The final rule, issued 1 January 1994, freezes...

Efficiency of Modified Zeolite with Cationic Surfactant Hexadecyltrimethylammonium Bromide in Removal of Diazinon from Aqueous Solutions

Background and purpose: Diazinon is one of the most widely used pesticides in agricultural pest control that pollutes water resources. The aim of this study was to evaluate the adsorption of diazinon from water by zeolite modified with cationic surfactant hexadecyltrimethyl ammonium bromide (HDTMA). Materials and methods: The amount of HDTMA surfactant used to modify the zeolite was one-fold E...

Photocatalytic Degradation of Humic Acid by Ag/ZnO Nanoparticles under UVC Irradiation from Aqueous Solutions

Introduction: Humic acid (HA) is one the original disinfection byproducts processors in water treatment. So, removing it is necessary before water chlorination. In the present study, photodegredation of humic acid in water using Ag/ZnO nano particle under UVc irradiation in batch system was investigated. Material and Methods: Photocatalytic study was carried out to evaluate the effect of UVc (...

Methyl bromide poisoning.

Methyl bromide is a highly volatile liquid which disperses rapidly and readily. As a fumigant it ranks amongst the most efficient because of its extremely effective penetrating power and absence of fire or explosion hazard. It is, unfortunately, highly toxic and poisoning occurs readily in circumstances of careless or inadvertent exposure. Before 1940, only 42 cases of methyl bromide poisoning ...
