上海市文教区大气中苯系物冬季污染特征

2004年冬天对上海市文教区大气中的苯系物(BTEX-苯,甲苯,乙苯和二甲苯)浓度进行了监测.结果表明,上海市文教区冬季苯、甲苯、乙苯、对问二甲苯、邻二甲苯的平均浓度分别为13.23 μg/m3,43.66 μ g/m3,13.50μg/m3,16.49 μ g/m3,5.52μg/m3,高于国内外相似功能区的苯系物浓度,与国外大城市交通干道附近的浓度相近.所测苯系物中,甲苯的含量最高,达47.3%.白天苯系物浓度高于夜间.甲苯、乙苯、二甲苯相互间具有较好的相关性,但与苯的相关性不显著,说明苯的来源不同与其他苯系物.     

Indoor air particles in research vessel from Shanghai to Antarctic: Characteristics, influencing factors, and potential controlling pathway

Despite millions of seafarers and passengers staying on ships each year, few studies have been conducted on the indoor air quality inside ship hulls. In this study, we investigated the levels and size distribution of indoor particulate matter during two cruises of the research vessel “Xuelong” from Shanghai to Antarctica. The results showed that the particle size less than 2.5 µm (PM_2.5), and particle size less than 10 µm (PM₁₀) concentrations in different rooms of the ship widely varied. We observed high particulate matter (PM) levels in some of the rooms. The mass concentration distribution was dominated by 1–4 µm particles, which may have been caused by the hygroscopic growth of fine particles. The dominant factors influencing PM concentrations were indoor temperature, relative humidity, and human activity. We quantified contributions of these factors to the levels of indoor particles using a generalized additive model. In clean rooms, the levels of indoor particles were controlled by temperature and relative humidity, whereas in polluted rooms, the levels of indoor particles were mainly influenced by temperature and human activity, which implied that controlling temperature and human activity would efficiently reduce the levels of indoor particles.     

空气微生物粒子沉降量指示太原空气污染状况

用平皿沉降法初步测定了太原的空气微生物粒子沉降量，结果表明太原空气中的微生物含理编高，其空气细菌，真菌，总菌含量分别为２４８１９．９，６２７．４和２５４４７．３ＣＦＵ／ｍ＾３，空气真菌在空气微立物总量中所占百分比率为２．４７，这意味着太原空气污染相当严重，空气质量不佳，文章分析了造成太原空气微生物含量增高的原因，提出了减轻空气污染，提高空气质量的一些措施。     

档案库房空气质量客观评价研究

采用大气质量指数评价方法。选定7个测定参数及3个背景测定参数；根据这一方法对天津市4座档案库房库内空气质量进行了测定，取得了大量数据。并据此确定了档案库房内空气质量的等级标准。同时对所测定的档案库房造成的空气质量的差异进行了分析比较。对改进库内空气质量提出了一些有益的建议。     

基于MapInfo和Surfer的大气污染物等值线绘制分析

提出了一种将地理信息系统软件MapInfo和3维绘图软件Surfer相结合，绘制大气污染物浓度等值线的新方法。该技术已经在石家庄东北工业区大气环境影响评价中得到应用，不仅保证了绘图分析精度，而互大大缩短了绘图和分析时间。     

抚顺市空气污染预报方案筛选

空气污染预报的准确性取决于大气污染物扩散模型的选取和预报方案的设计。本文以经过验证的ADMS-大气污染物扩散模型为基础。设计了四种预报方案。并对四种方案的预报准确性进行检验，从而筛选出了适用于抚顺市空气污染特点的最佳预报方案。

中国人居空间环境污染状况及防治策略--室内、汽车、冰箱的污染情况及防治方法

随着社会的发展，人们在室内和汽车内的时间占人一生中总的时间的90％还多。而且室内环境的好坏直接影响我们的身体健康。同时冰箱引起的健康问题逐渐被人们所重视。     

Prenatal diagnosis of a new syndrome: Holoprosencephaly with hypokinesia

Markedly decreased fetal activity (akinesia/hypokinesia) is usually readily apparent to experienced mothers, and frequently this concern leads to attempts at prenatal diagnosis. We report prenatal diagnosis of two fetuses with congenital contractures, markedly decreased fetal movement, and microcephaly due to severe holoprosencephaly. Such familial recurrence to phenotypically normal parents suggests a newly recognized autosomal recessive or X-linked syndrome that is readily detectable by prenatal ultrasonography.     

液化石油气推广应用的可行性研究
