Pollution property of particulates in the air at the traffic crossing in beijing part : pollution property of pahs in the particulates in the air 北京市不同区域采暖期大气颗粒物中多环芳烃的分布特征
The paper introduced the research progress of source apportionment of airborne particulate matter from receptor model , sample treatment , the latest development tendency 本文从受体模型、样品的处理技术、源解析技术发展的最新趋势三方面介绍了大气颗粒物源解析技术的研究进展。
Chromium copper lead manganese zinc nickel and iron in atmospheric particulates were determined by icp - aes with a new sampling method of atmospheric particulates using polypropylene filter 摘要聚丙烯膜采集大气颗粒物中的铬、铜、铅、锰、锌、镍和铁，消解后用icp - aes法进行测定。
According analysis of tsp density and the density and modality of sulfide and combining with the question of acid rain in the east suburb of chengdu atmosphere in the first half of 2006 , the present air environmental pollution condition in chengdu was explored . on the basis of collecting the conference concerned and researching , the main modality and density of sulfide were discussed , then the relation between sulfide with acid rain was analysed , put forward suggerstion and solution 通过分析2006年上半年成都市东郊大气中总悬浮颗粒物及其中硫化物的含量和形态并结合酸雨问题阐述了成都市大气颗粒物的污染状况,并在搜集有关资料及实验的基础上,对成都东郊tsp中的硫化物的主要形态和含量作了初步的探讨,同时分析了硫化物与酸雨的联系,得出了结论并提出了建议。
Glutathione redox system as the important parts of defense systems was studied after exposure to sulfur dioxide at different concentrations . dna damage caused by so2 and lead acetate were also studied . protective roles of seabuckthorn seed oil on oxidative damage caused by so2 in liver and lung of mice were also investigated 本文在整体动物水平上研究了不同浓度二氧化硫吸入后小鼠组织谷胱甘肽氧化还原系统( glutathioneredoxsystem )的动态变化规律；二氧化硫所致氧化损伤的防护作用研究；二氧化硫和大气颗粒物中亲气性重金属元素铅对dna的联合损伤作用。
Dna damages caused by so2 and lead acetate were studied with the single cell microgel electrophoresis technique ( or comet assay ) in order to confirm the damaging degree of lead ( as an important component of atmosphere particle matter ) on dna from male mice exposed to so2 . the migrating distances of dna of brain , lung , spleen and kidney cells of mice increased significantly , compared to the control group under conditions of single and combined poisoning of so2 ( 42mg / m3 ) and lead acetate ( 0 . 2 % ) , and lead could strengthen dna damage degree by so2 in nuclear dna of brain , kidney , spleen cells . damaging degree of so2 on nuclear dna of lung cell of mice was more severe than that of lead 为了明确大气颗粒物中的重要组分? ?铅在二氧化硫所致dna损伤中的作用程度，利用单细胞凝胶电泳技术( singlecellgelelectrophoresis ， scge ，或称彗星实验， cometassay )研究了铅与二氧化硫的联合污染，结果表明在42mg m ~ 3so _ 2和0 . 2醋酸摘要一abstract铅单独及联合染毒条件下，小鼠脑、肺、肾、脾细胞dna迁移距离均比对照显著增加;铅加剧了50 :对脑、肾、脾细胞核dna的损伤程度; 50 :对肺细胞核dna的损伤程度要比铅的损伤大，小鼠肺细胞核dna迁移距离在50 :和醋酸铅联合作用组与醋酸铅单独作用组间有极显著性差异( p < 0 . 01 ) ，而与502单独作用组间没有显著性差异。
