本文测定了金泽降水中1，3-、1，6-和1，8-二硝基芘，1-、2-和4-硝基芘，6-硝基蒽和2-硝基荧蒽等8种硝基芳烃。沉淀中的硝基芳烃被浓缩到固相萃取柱上，用高效液相色谱-化学发光检测器鉴定。大气颗粒物中硝基芳烃的浓度范围为0.016-15 pmol/L，其组成与大气颗粒物中的硝基芳烃组成基本一致。还测定了河水和海水中的I-硝基芘。1-雨后的硝基芘浓度（19-110 fmol/L）高于雨前（4、11 fmol/L）。河水中1-硝基芘的浓度远低于降水中的浓度，但高于海水中的浓度。这些结果表明，降水和河水中的硝基芳烃来自大气颗粒物。(C)2001爱思唯尔科技有限公司版权所有。
Eight nitroarenes, 1,3-, 1,6- and 1,8-dinitropyrenes, 1-, 2- and 4-nitropyrenes, 6-nitrochrysene and 2-nitrofluoranthene, in precipitation collected in Kanazawa were determined. The nitroarenes in the precipitation were concentrated onto solid phase extraction cartridges, and identified with highperformance liquid chromatography with chemiluminescence detection. The nitroarene concentrations in the precipitation were in the range 0.016-15 pmol/L, and the nitroarene composition tended to be the same as that in airborne particulates. I-Nitropyrene in river water and seawater were also determined. 1-nitropyrene concentrations on the days after rain (19-110 fmol/L) were higher than those on the days before rain (4,11 fmol/L). Moreover, 1-nitropyrene concentrations in the river water were much lower than those in the precipitation, but were higher than those in the seawater. These results suggested that the nitroarenes in the precipitation and the river water came from airborne particulates. (C) 2001 Elsevier Science Ltd. All rights reserved.
