We have developed a simple, rapid, inexpensive method for the identification of fluoranthene (Flan), benz(a)anthracene (BaA), benzo(a)pyrene (BaP), benzo(k)fluoranthene (BkF), pyrene (Pyr), benz(ghi)perylene (BghiP) in suspended particulate matter in an urban environment of Delhi. Suspended particulate matter samples of 24h duration were collected on glass fiber filter papers. Polycyclic aromatic hydrocarbons (PAHs) were extracted from the filter papers using dichloromethane (DCM) and hexane with ultrasonication method. Comparison of the characteristic emission of spectra of PAHs with standard spectra indicated the degree of condensation of aromatic compounds present in investigated mixtures. It was also possible to identify some individual compounds. However, this identification could be more effective with the use of the respective values of Δλ parameter for each particular component of the mixture.
我们开发了一种简单、快速、廉价的方法，用于鉴定悬浮颗粒物中的荧蒽（Flan）、苯并（a）蒽（BaA）、苯并（a）芘（BaP）、苯并（k）荧蒽（BkF）、芘（Pyr）、苯并（ghi）苝（BghiP）。悬浮颗粒物样品采集时间为 24 小时，采集在玻璃纤维滤纸上。多环芳烃（PAHs）采用二氯甲烷（DCM）和正己烷超声提取法从滤纸上提取。将 PAHs 的特征发射光谱与标准光谱进行比较，表明了所研究混合物中芳香化合物的缩合程度。也可以识别出一些个别化合物。然而，使用混合物中每个特定成分的相应Δλ参数值，这种鉴定可能会更有效。
