简介：在这研究，acoupled地区性的空气质量建模系统被使用调查时间在在空中的微粒事(PM10)的空间变化，在2004年4月17日的时期从Mentougou发源到北京市政的区域，并且在边界层之上的复杂地面和气象学的条件的影响组织并且PM10集中分布。有对观察数据的CALPUFF的表演的intercomparison被介绍并且考试散布阴谋被提供。统计证明在建模并且观察的数据之间的关联系数和性传播疾病分别地是0.86和0.03。模型结果的分析说明从Mentougou射出的污染物质能沿着某些运输小径被搬运到北京市政的区域，并且PM10集中分布显示出异质特征。到在北京市政的区域的PM10集中的Mentougou来源的贡献直到0.115g/m3。

简介：在这研究，有机物(OM)和在来自北华南海(SCS)的表面沉积的类脂化合物biomarkers的内容和分发被识别揭示有细密纹理的沉积的来源和运输。有机物和类脂化合物biomarkers在北SCS展出了不同空间变化。来自在西南的台湾的珍珠河和一些多山的河的陆上的分泌物可以在相应的海区域贡献相对高的有机物。不饱和的丰满的酸相当或相同事物的察觉建议了海藻或细菌的OM贡献到表面沉积。类脂化合物biomarkers的composites和分发从陆上的植物显示他们的混合来源，海洋的水藻并且细菌。和在沉积的泥土矿物质composites的证明，结果建议包括广东沿海的水流和自台湾东面的菲律宾海流向日本的暖流电流，水流在北SCS控制陆上的沉积和沉积环境的运输和分发。
