Occurrence and distribution of chlorinated and non-chlorinated organophosphates in 72 groundwater samples from Germany under different recharge/infiltration conditions were investigated. Tris(2-chloro-1-methylethyl) phosphate (TCPP) and tris(2-chloroethyl) phosphate (TCEP) were the most frequently detected organophosphates in groundwater samples. Highest individual organophosphate concentrations (>0.1 µg L(-1)) were determined in groundwater polluted by infiltrating leachate and groundwater recharged via riverbank filtration of organophosphate-loaded recipients. In samples from springs and deep groundwater monitoring wells that are not affected by surface waters, organophosphate concentrations were mostly below the limit of detection. The occurrence (3-9 ng L(-1)) of TCPP and TCEP in samples from aquifers with groundwater ages between 20 and 45 years indicates the persistence of both compounds within the aquifer. At urban sites organophosphate-loaded precipitation, surface runoff, and leakage of wastewater influenced groundwater quality. For rural sites, where groundwater recharge is only influenced by precipitation, organophosphates were very rarely detectable in groundwater.
研究了德国72个不同补给/渗透条件下的地下水样品中氯化和非氯化有机磷酸酯的出现情况和分布。磷酸三(2-氯-1-甲基乙基)酯(TCPP)和磷酸三(2-氯乙基)酯(TCEP)是地下水中最常检测到的有机磷酸酯。在受渗滤液污染的地下水以及通过有机磷酸酯污染受体的河岸过滤补给的地下水中,测定出最高的单个有机磷酸酯浓度(>0.1 µg L⁻¹)。在不受地表水影响的泉水和深层地下水监测井的样品中,有机磷酸酯浓度大多低于检测限。在地下水年龄为20至45年的含水层样品中,TCPP和TCEP的出现情况(3-9 ng L⁻¹)表明这两种化合物在含水层中的持久性。在城市地区,有机磷酸酯负载的降水、地表径流和废水泄漏影响了地下水质量。对于农村地区,地下水补给仅受降水影响,地下水中很少能检测到有机磷酸酯。
