摘要

多环芳烃(PAHs)、多氯联苯(PCBs)和有机氯农药(OCPs)因其对生物的有害影响,一直是大气中的重要监测目标。松针已被用于监测大气污染物。本研究采用超声辅助萃取和气相色谱-串联质谱法(GC-MS/MS)开发了一种分析方法,用于测量松针中的 21 种 PAHs、14 种烷基 PAHs、7 种 PCBs 和 23 种 OCPs。多环芳烃、多氯联苯和 OCP 的检测下限范围分别为 0.01-0.05、0.02-0.06 和 0.01-0.07 μg/kg。该方法的精密度为0.83%~7.80%(多环芳烃)、0.93%~4.78%(多氯联苯)和0.73%~4.71%(OCPs),准确度为89.2%~102%(多环芳烃)、94.6%~109%(多氯联苯)和99.4%~102%(OCPs)。利用所开发的方法对真实松针样品中的多环芳烃、多氯联苯和 OCPS 进行了测定。

Method development for gas chromatography-tandem mass spectrometry analysis of trace level polycyclicaromatic hydrocarbons, alkyl polycyclicaromatic hydrocarbons, polychlorinated biphenyls, and organochlorinepesticides in pine needle specimen

Polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs) have been important monitoring targets in the atmosphere due to their deleterious biological effects. Pine needles have been used to monitor atmospheric pollutants. An analytical method was developed to measure 21 PAHs, 14 alkyl PAHs, 7 PCBs, and 23 OCPs in pine needles using ultrasonically assisted extraction and gas chromatography-tandem mass spectrometry (GC–MS/MS). The ranges of the lower limits of detection of PAHs, PCBs, and OCPs were 0.01–0.05, 0.02–0.06, and 0.01–0.07 μg/kg, respectively. The feasibility of the proposed method was validated by analyzing dust standard reference materials of the samples, which gave satisfactory results with a precision of 0.83%–7.80% (PAHs), 0.93%–4.78% (PCBs), and 0.73%–4.71% (OCPs), and an accuracy of 89.2%–102% (PAHs), 94.6%–109% (PCBs), and 99.4%–102% (OCPs). The PAHs, PCBs, and OCPS were determined from real pine needle samples using the developed method.
