Simultaneous analytical method for urinary metabolites of organophosphorus compounds and moth repellents in general population

► We develop an analytical method of 15 urinary metabolites in general population. ► They are exposed to organophosphorus compounds and moth repellents. ► The metabolites from hydrolyzed urine are analyzed by GC/MS(EI) after derivatization. ► They can be measured accurately and precisely (quantification limits: 0.8-4 μg/l). ► The collected urine samples can be stored for up to 1 month at −20 °C in a freezer.
