舞鹤湾水样中有机磷酸三酯的浓度范围为3.0-62纳克/升。总的来说，OPEs的浓度为TBXP > TDCPP > TCEP > TBP > TCP > TPP > TEP。水样中检出二嗪农、杀螟松、异稻瘟净和毒死蜱等有机磷农药。舞鹤湾沉积物中OPEs的浓度范围为TDCPP > TCP > TBXP = TPP = TCEP。在贻贝中检测到农药，但这些浓度低于每日允许摄入量值。二嗪农和杀螟硫磷在水和沉积物中的分配系数分别为200-1300和200-300，在生物样品中的分配系数分别为700-3300和450-700，表明这两种农药在生物样品中的富集速率高于沉积物。
The concentrations of organophosphoric acid triesters (OPEs) in water samples from Maizuru Bay were in the range of 3.0–62 ng/l. In general, the concentrations of OPEs were found in the order of TBXP > TDCPP > TCEP > TBP > TCP > TPP > TEP. The organophosphorous pesticides (OPPs) diazinon, fenitrothion, iprobenfos and chlorpyrifos were detected in water samples. The concentrations of OPEs in sediment from Maizuru Bay were in the range of TDCPP > TCP > TBXP = TPP = TCEP. Pesticides were detected in mussels, but these concentrations were lower than the acceptable daily intake (ADI) values. The partition coefficients between water and sediment (Kws) of diazinon and fenitrothion were 200–1300 and 200–300, respectively and the partition coefficients between water and biological samples (Kwb) of diazinon and fenitrothion were 700–3300 and 450–700, respectively, suggesting that these pesticides accumulate in biological samples at higher rates than in sediment.
