Flounders from the three different and relatively distant sites in the Gulf of Gdańsk were collected in august and october 1992 and analysed to investigate a potential differences in concentration and composition of chloronaphthalenes. The method of PCNs measurement was capillary gas chromatography and high resolution mass spectrometry (HRGC/HRMS) after a nondestructive extraction and cleanup step via dialysis with polyethylene membrane and than HPLC preseparation on a activated carbon column. Chloronaphthalenes were separated and quantified on RTx-5 capillary column using an electron impact (EI) mode and selective ion recording (SIR). All samples contained detectable concentrations of many tetra-, penta- and heksachloronaphthalenes, and the total PCNs concentration ranged from 1700 to 3900 pg/gwet weight. A substantial difference in pattern and concentration of PCNs residues in flounders between some of the sampling sites were found.
1992年8月和10月，从格但斯克湾三个不同且距离相对较远的地点采集了比目鱼，并对其进行分析，以研究氯萘浓度和成分的潜在差异。多氯萘的测量方法是在通过聚乙烯膜透析进行无损萃取和净化步骤后，再在活性炭柱上进行高效液相色谱预分离，然后采用毛细管气相色谱和高分辨率质谱法（HRGC/HRMS）。使用电子轰击（EI）模式和选择性离子记录（SIR）在RTX-5毛细管柱上分离并定量氯萘。所有样品中都含有可检测浓度的多种四氯、五氯和六氯萘，多氯萘的总浓度范围为1700至3900 pg/g湿重。在一些采样点之间的比目鱼中，多氯萘残留的模式和浓度存在显著差异。
