摘    要:为了研究焦化厂大气可吸入颗粒物(PM10)、梧桐叶片、土壤3介质中PAHs的污染特征、来源及相关性,连续1 a采其周边PM10、梧桐叶片及土壤样品,利用美国EPA8000系列方法进行分析.结果发现,PM10、梧桐叶片、土壤3种介质中PAHs总量年平均值分别为101.11 ng/m3、79.45 ng/g和121.53 μg/g;PM10中苯并(a)蒽、苯并(g,h,i)、荧蒽、苯并(a)芘等高环数的多环芳烃占明显优势;在梧桐叶片中萘、苊、苯并(a)芘和苯并(g,h,i)的含量较高;土壤中苊烯、芘、苯并(a)蒽等3和4环的PAHs占较大比例. 5月梧桐树叶中只含有苊和芘,而且浓度较低,分别为0.16 ng/g和0.63 ng/g;7、8月梧桐叶中PAHs总量显著提高,从39.19 ng/g上升到150.94 ng/g.通过相关性推断,焦化厂PAHs主要来源为复合污染; 梧桐叶片中PAHs各组分浓度与土壤和PM10中各组分的浓度均具有极显著的相关性(p<0.01).

关 键 词:焦化厂  PM10  梧桐叶片  土壤  PAHs

Abstract:In order to study the distributions characteristics, sources and relationship of PAHs in PM10- phoenix tree leaves-soil system of a coking & chemical factory in Shanghai, the samples of PM10, phoenix tree leaves and soil around the factory were collected for a year. The concentration of PAHs were analyzed according to the USEPA method 8 000 series. The results showed that the average concentration of PAHs in PM10, phoenix tree leaves and soil were 101.11 ng/m3, 79.45 ng/g and 121.53 microg/g, respectively. Particulate phase (PM10) contained mainly carcinogenic and mutagenic PAHs, among which BaA, BghiP, Flu and BaP were found at significant concentrations. In phoenix tree leaves, Nap,Chy, BaP and BghiP presented a higher level of concentration. In soil, 3 and 4-ring PAHs presented a higher level. PAHs concentrations of phoenix tree leaves were very lower in May. Only Ace (0.16 ng/g) and Pyr (0.63 ng/g) were detected. In July and August the concentrations (39.19 ng/g and 150.94 ng/g, respectively) were uplifted significantly. It could be concluded PAHs was from petroleum and coal-fired compound source. There were very strong positive relationships of 16 PAHs level among phoenix tree leaves, soil and PM10 (p < 0.01).
Keywords:coking & chemical factory  PM10  phoenix tree leaves  soil  PAHs
