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.
