The amounts, profiles and origin of CNs (from triCNs to octaCN) sequestered in Scots pine needles collected from 25 spatially distant sites in Poland have been studied based on congener-specific data obtained after a several clean-up and fractionation steps and final HRGC/HRMS separation and determination. The absolute concentrations of CNs varied largely from site to site, i.e., by 15-fold. The sum of tri- to octaCN concentration at fifteen of the least contaminated sites ranged from 70 to 280 pg g(-1) ww, and at further eight sites were from 340 to 540 pg g(-1) ww, while at two the most contaminated were 1000 and 1100 pg g(-1)ww. There were some substantial similarities but also variations in triCN to octaCN homologue group profiles depending on the site. Among triCNs the isomers such as 1,2,4-/1,3,7-/1,4,6-triCNs (nos. 14/21/24) dominate in Scots pine needles. For majority of the sites examined 1,2,4-/1,3,7-/1,4,6-triCNs are also the major contributors to the bulk of CNs determined. Among tetraCNs isomer 1,2,5,8-tetraCN (no. 38) was dominant contributor at eighteen sites, while 1,2,4,6-/1,2,4,7-/1,2,5,7-tetraCN (nos. 33/34/37) at seven other sites. In the case of pentaCNs isomer 1,2,4,5,8-pentaCN (no. 59), was dominant contributor alone. Octachloronaphthalene frequently contributed substantially to the bulk of CNs. The Cluster Analysis and Principal Component Analysis did indicate that the compositional profiles of CNs found in Scots pine needles resemble somehow these found in the bottom ashes after coke and coal burning as well as of Halowax 1000 and 1099 formulations.
基于经过几步净化和分馏步骤以及最终的高分辨率气相色谱/高分辨率质谱分离和测定后获得的同系物特异性数据，对从波兰25个空间距离较远地点采集的苏格兰松针中螯合的多氯萘（从三氯萘到八氯萘）的含量、分布和来源进行了研究。多氯萘的绝对浓度在不同地点之间差异很大，即相差15倍。在15个污染最轻的地点，三氯萘到八氯萘的浓度总和在70至280 pg g(-1)湿重之间，在另外8个地点为340至540 pg g(-1)湿重，而在两个污染最严重的地点分别为1000和1100 pg g(-1)湿重。根据地点不同，三氯萘到八氯萘同系物组的分布存在一些显著的相似之处，但也有差异。在三氯萘中，1,2,4-/1,3,7-/1,4,6-三氯萘（编号14/21/24）等异构体在苏格兰松针中占主导地位。在所检查的大多数地点，1,2,4-/1,3,7-/1,4,6-三氯萘也是所测定的多氯萘总量的主要贡献者。在四氯萘中，异构体1,2,5,8-四氯萘（编号38）在18个地点是主要贡献者，而1,2,4,6-/1,2,4,7-/1,2,5,7-四氯萘（编号33/34/37）在其他7个地点是主要贡献者。在五氯萘的情况下，异构体1,2,4,5,8-五氯萘（编号59）单独是主要贡献者。八氯萘经常对多氯萘总量有很大贡献。聚类分析和主成分分析确实表明，在苏格兰松针中发现的多氯萘的组成分布在某种程度上类似于在焦炭和煤炭燃烧后的底灰以及Halowax 1000和1099配方中发现的分布。
