General description

4-Chloro-2-methylphenoxyacetic acid (MPCA) is a herbicide. Various MCPA-mineralising bacterial combinations has been tested using a high-throughput microplate radiorespirometric mineralisation assay. Degradation mechanisms of OH and MCPA including molecular form and anionic form have been studied. Rapid and sensitive LC-electrospray tandem mass spectrometry method has been developed for the quantitation of MCPA in water and soil samples.

The herbicide 4-chloro-2-methylphenoxyacetic acid (MCPA) is found frequently in Danish groundwater in concentrations exceeding the EU threshold limit of 0.1 µg L(-1) . Groundwater is used for drinking water, and one potential remediation strategy is bioaugmentation using inoculation of sand filters at

The initial degradation mechanisms of ⁱOH and 4-chloro-2-methylphenoxyacetic acid (MCPA) including molecular form and anionic form are studied at the MPWB1K/6-311+G(3df, 2p)//MPWB1K/6-31+G(d, p) level. Possible reaction pathways of H-atom abstraction and ⁱOH addition are considered in detail. By result comparison

Two 4-chloro-2-methylphenoxyacetic acid (MCPA)-degrading enrichment cultures selected from an aquifer on low (0.1 mg liter(-1)) or high (25 mg liter(-1)) MCPA concentrations were compared in terms of metabolic activity, community composition, population growth, and single cell physiology. Different community compositions

Herbicide leaching through soil into groundwater greatly depends upon sorption-desorption and degradation phenomena. Batch adsorption, desorption and degradation experiments were performed with acidic herbicide MCPA and three soil types collected from their respective soil horizons. MCPA was found to be
