利用超薄切片透射电镜分析技术，分析了鄂尔多斯盆地石炭二叠纪及中生代煤的超微特征，发现镜质组中普遍存在常规光学显微镜下不能识别的超微类脂体，并且镜质组的荧光性质、热演化程度和生烃潜力与超微类脂体数量密切相关。此外，煤的SAD分析表明，随煤级增加，层间距d（002）逐渐变小，且在低变质烟煤—中变质烟煤阶段变化较显著，在高变质烟煤阶段则变化缓慢。

采用显微傅利叶红外光谱（Micro-FTIR）研究了源岩中三个系列显微组分包括陆生高等植物成因的镜质体、丝质体、木栓质体、孢子体、角质体，水生动物成因的笔石、几丁虫及热演化过程中次生的组分沥青等的化学组成与结构演变特征。研究表明，所有显微组分随其演化程度增高，脂族链变短，含氧官能团减少，芳烃富集且芳环缩合度增加。镜质体含丰富的芳烃C=C，壳质组含丰富的脂族烃C-Hx，笔石、几丁虫含丰富的含氧官能团和氧桥（C-O-C及Ar-O-Ar等），沥青的脂族烃C-Hx含量介于壳质组与镜质体之间，丝质体含丰富的芳烃C=C及氧桥。

Coal-bearing strata in the Antaibao surface mine, Pingshuo mining district Shanxi, China occur in the Taiyuan Formation (Upper Carboniferous. and Shanxi Formation (Lower Permian). The most productive coal seams in the mine are the Nos. 11, 9 and 4. Twenty-five samples of coals, partings, and roof shales from the Nos. 11, 10, 9, 5 (Taiyuan Formation), and 4 (Shanxi Formation. seams in the Antaibao mine were analyzed for ash, and total sulfur contents and forms of sulfur. The No. 11 seam is a medium-to high-sulfur coal (1.3-3.1%S). A coal sample (14.1%ash) from the No. 10 seam contains 3.4%, and high ash coal (37.4%ash. from the same seam contains only 0.4%total sulfur. The No. 9 seam is a low-to medium-sulfur coal (0.6-1.3%S). The highest sulfur content among the samples is 5.8%total sulfur from a coal sample of the No.5 seam. The No. 4 seam is low-sulfur coal (0.29-0.54%S). The remarkable variation in sulfur content among the coal seams in the Taiyuan and Shanxi Formations could reflect different depositional environments; from coastal to lower deltaic plain for the Taiyuan, and from upper deltaic plain to fluvial basin for the Shanxi Formation. The sulfate sulfur comes mainly from the oxidation of pyrite. Sixteen samples were analyzed for 26 major, minor and trace elements by X-ray fluorescence spectrometry. The Sr content is significantly higher in coals from the No. 4 seam in the Shanxi Formation than those from Nos. 11 to 5 seams. Chlorine, Sr, Ca and P are elements bound organically; while Si, Al, Ti, Fe, K, Na, Mg, Cr, V, Ni, Rb, Ba and Nb are mainly associated with minerals.

对北京首钢地区大气颗粒物中有机物浓度、族组成及其饱和烃、多环芳烃的组成和分布特征进行了研究。在大气颗粒物中共检测出40多种多环芳烃，其中属于美国国家环保局（EPA）优先控制污染物9种，且大多具有致癌和致突变性。根据生标特征，有机污染物主要来源于煤的不完全燃烧，部分来源于汽车尾气的排放。燃煤对首钢地区造成的污染更为严重。

对首钢焦化厂炼焦过程中生成多环芳烃的分布特征进行了初步研究。焦化厂环境中共检测出40多种多环芳烃，其中属于美国国家环保局（EPA）优先控制污染物9种，且大多具有致癌和致突变性。多环芳烃的稳定碳同位素可以初步确定环境颗粒物中PAHs的来源，以及是否混有未燃烧、燃烧不完全或干馏中间产物的颗粒物。研究表明，煤中多环芳烃通过焦化作业以烟尘、煤粒、焦末以及外排废水形式迁移而污染大气、土壤和水环境。
