The seasonal intensive sampling of gases and particulate matter in ambient air was conducted at the site established in urban area of Japan to study the seasonal difference of the temporal variation of gases and particulate matter concentrations in urban atmosphere as well as to illustrate the different transport regimes that impacts air pollutants. The sample was collected by the four-stage filter-pack method with 6-h interval for one week in four seasons (spring, summer, autumn and winter). The trans-boundary transport of air pollutants with high concentration was characteristically observed in the spring sampling. On the other hand, we could successfully detect the in-country transports of air pollutants in the summer sampling. Four-season’s intensive survey considered, we could show the characteristic transport of air pollutants to provide the episodic high concentration for ambient air in the urban area of Japan, and successfully illustrate the seasonal-dependent transport regimes to impact on air pollutants.

通过高频过滤包采样方法观察到的日本神户空气污染物的跨界和国内传输

在日本城市地区设立的地点对环境空气中的气体和颗粒物进行季节性集中采样，以研究城市大气中气体和颗粒物浓度随时间变化的季节性差异，并说明不同的运输方式从而影响空气污染物。样品采用四级滤袋法收集，每 6 小时间隔 1 周，四个季节（春、夏、秋、冬）。在春季采样中观察到高浓度空气污染物的跨界迁移特征。另一方面，我们可以在夏季采样中成功检测到空气污染物的国内传输。考虑了四个赛季的密集调查，
