Intentional self-poisoning with the chlorophenoxy herbicide 4-chloro-2-methylphenoxyacetic acid (MCPA).
STUDY OBJECTIVE Data on poisoning with MCPA (4-chloro-2-methyl-phenoxyacetic acid) are limited to 6 case reports. Our objective is to describe outcomes from intentional self-poisoning with MCPA in a prospective case series of 181 patients presenting to hospitals in Sri Lanka. METHODS Patient information was collected by on-site study physicians as part of an ongoing prospective cohort study o...
متن کاملMetabolism of 4-chloro-2-methylphenoxyacetic Acid by soil bacteria.
A microorganism capable of degrading 4-chloro-2-methylphenoxyacetic acid (MCPA) was isolated from soil and identified as Flavobacterium peregrinum. All of the chlorine of MCPA was released as chloride, and the carboxyl-carbon was converted to volatile products by growing cultures of the bacterium, but a phenol accumulated in the medium. The phenol was identified as 4-chloro-2-methylphenol on th...
متن کاملComparative sorption and leaching study of the herbicides fluometuron and 4-chloro-2-methylphenoxyacetic acid (MCPA) in a soil amended with biochars and other sorbents.
Biochar, the solid residual remaining after the thermochemical transformation of biomass for carbon sequestration, has been proposed to be used as a soil amendment, because of its agronomic benefits. The effect of amending soil with six biochars made from different feedstocks on the sorption and leaching of fluometuron and 4-chloro-2-methylphenoxyacetic acid (MCPA) was compared to the effect of...
متن کاملComparison of Mineralization Dynamics of 2,4-Dichlorophenoxyacetic Acid (2,4-D) and 4-Chloro-2-Methylphenoxyacetic Acid (MCPA) in Soils of Different Textures
The degradation behaviour of 2,4-D and MCPA in four types of soil were determined from measurements of 14CO2 evolution over a period of 100 days. The total C-organic volatile compounds evaporated from the soils during the experimental period and the residual C in the soils at the end of the incubation period was also determined. The degree of mineralization was different for tested pesticides, ...
متن کاملDifferences in sorption behavior of the herbicide 4-chloro-2-methylphenoxyacetic acid on artificial soils as a function of soil pre-aging
PURPOSE The sorption behavior of the herbicide 4-chloro-2-methylphenoxyacetic acid (MCPA) to three different artificial soil mixtures was investigated. Artificial soils serve as model systems for improving understanding of sorption phenomena. MATERIALS AND METHODS The soils consisted of quartz, ferrihydrite, illite, montmorillonite, and charcoal. In a previous study, several selected mixtures...
