Subaquatic sediment samples derived form Elbe and Mulde Rivers, Germany, were analyzed for extractable and non-extractable anthropogenic organic compounds by a non-target screening approach. Applied methodologies were gas chromatography-mass spectrometry, dispersion extraction and degradation procedures, particularly alkaline and acidic hydrolysis, boron tribromide treatment, ruthenium tetroxide oxidation
通过非目标筛选方法分析了来自德国易北河和穆尔德河的亚水底沉积物样品中可提取和不可提取的人为有机化合物。应用的方法是气相色谱-质谱法,分散体提取和降解程序,特别是碱和酸性水解,三溴化硼处理,四氧化钌氧化以及热解和TMAH(氢氧化四甲铵)-热化学法。鉴定出许多化合物,包括卤代苯,茴香醚,苯乙烯,烷烃,二苯甲烷衍生物,苯胺,苯酚和二苯醚。结合化合物的特定掺入方式以及潜在来源(例如市政,农业,工业)对结果进行了解释。可萃取和不可萃取馏分的定性和定量组成差异很大。例如,氯化苯的可萃取和不可萃取馏分中的含量差异最大为50。除其他重要结果外,研究还显示出氯化苯的掺入方式取决于其取代方式。
