本研究的目的是比较摩拉维亚-西里西亚工业地区NH3、nox和so2排放源的浓度和同位素监测。2014-2015年，我们使用酸和碱处理过的过滤器在管式被动采样器中收集气体。测定样品的浓度和15n、34s同位素组成。从δ15N值（4 ~ - 45‰）来看，nh3污染来源于畜禽粪便中氨在冬季的挥发，且同位素分馏显著。nox源主要来源于夏季车辆尾气排放（δ15N在−8 ~−2‰之间）和冬季化石燃料燃烧（δ15N在−5 ~ 20‰之间）。夏季本地工业源的so2排放量较低（平均约为3 μg m−3）（δ34S约为−1.4‰或更高）。冬季，来自波兰上西里西亚地区的跨境输送（δ34S约为- 2.5‰）增加了（平均约为12 μg m - 3）。
The aim of this study is to compare the concentration and isotopic monitoring of sources of emission of NH3, NOxand SO2in the industrial Moravia-Silesian region. We collected gases in tube-type passive samplers with acid and alkali treated filters during 2014–2015. The collected samples were measured for concentration and15N and34S isotopic composition. According to δ15N values (from 4 to −45‰), the NH3pollution originates from the volatilization of ammonia from livestock (poultry) wastes with significant isotope fractionation during the winter. The NOxsources originate from vehicle emissions (δ15N from −8 to −2‰) in the summer, with the addition of fossil fuel combustion in the winter (δ15N from −5 to 20‰). The SO2emissions are low in the summer (on average around 3 μg m−3) from local industrial sources (δ34S around −1.4‰ and more). An increase in winter (on average to about 12 μg m−3) is produced by trans-border transport from the Upper Silesian region of Poland (δ34S about −2.5‰).
