Human urine was analyzed for nine dialkyl (DAP) and five monoalkyl phosphates (MAP) by LC-MS/MS. Some phosphoric acid esters are industrial chemicals and other hydrolysis products of trialkyl or triaryl phosphates, used as pesticides, flame retardants or plasticizers. Five MAP and two DAP were detected here for the first time in human urine. Monobutyl, diethyl. diphenyl and diethylhexyl phosphate were determined with median concentrations in the mu g/L-range. The total urinary concentration of the 14 DAP and MAP summed up to a median of 20 mu g/L. Inclusion of MAP in future biomonitoring studies should provide a more comprehensive picture of the exposure of humans to organophosphorus compounds. (C) 2011 Elsevier B.V. All rights reserved.
