重度雾霾环境下篮球运动对人体心肺机能的影响研究

雾霾一直是影响人体健康的始作俑者之一,重度雾霾环境下人体的各项机能均会下降,甚至衰竭。针对重度雾霾环境下篮球运动对人体心肺机能的影响开展下列研究:对雾霾天气形成因素进行详细研究,经研究发现在城市中,有毒的颗粒物主要来源于汽车尾气、北方抵御冬季供暖生成的废气、工业生产中排放的气体、建筑工地与马路交通生成的扬尘等方面,特别是在长三角和珠三角地区,每年出现雾霾的天数要在100天以上,且个别城市超过了200天;将雾霾环境下篮球运动对人体心肺机能的影响划分为:易导致呼吸道及肺组织交叉感染、易导致慢性阻塞性的肺部疾病、易导致肺癌三大模块,并对形成的原因进行详细阐述。     

基于医疗大数据的空气污染类疾病信息分析研究

世界卫生组织表示,空气污染为造成全球疾病负担的一项重要因素,能够导致心血管疾病、呼吸系统疾病等各种疾病的发生,空气污染问题已经成为公共卫生领域关注的重点问题,对基于医疗大数据的空气污染类疾病信息进行分析。利用半参数广义相加的泊松回归模型,在控制时间、长期趋势、气象因素等一些复杂条件的基础上,对2012年1月1日至2016年12月31日,某市空气中SO2、PM10和NO2等一些主要空气污染物的监测浓度值与呼吸系统疾病(肺炎以及支气管炎与哮喘)住院人数的相关性进行研究,研究结果表明,空气颗粒物PM10对患病率的影响相对于气态污染物SO2、NO2更为严重。     

Bi-national assessment of the Great Lakes: SOLEC partnerships

Many administrative jurisdictions have authority over parts of the Great Lakes, sometimes with competing purposes as well as governance at differing scales of time and space. As demand increases for high quality information that is relevant to environmental managers, environmental and natural resource agencies with limited budgets must look to interdisciplinary, collaborative approaches for the collection, analysis and reporting of data. The State of the Lakes Ecosystem Conferences (SOLEC) were begun in 1994 in response to reporting requirements of the Great Lakes Water Quality Agreement between Canada and the U.S. The biennial conferences provide independent, science-based reporting on the state of health of the Great Lakes ecosystem components. A suite of indicators necessary and sufficient to assess Great Lakes ecosystem status was introduced in 1998, and assessments based on a subset of the indicators were presented in 2000. Because SOLEC is a multi-agency, multi-jurisdictional reporting venue, the SOLEC indicators require acceptance by a broad spectrum of stakeholders in the Great Lakes basin. The SOLEC indicators list is expected to provide the basis for government agencies and other organizations to collaborate more effectively and to allocate resources to data collection, evaluation and reporting on the state of the Great Lakes basin ecosystem.

Occurrence and congeners specific of poiychlorinated biphenyls in agricultural soils from Southern Jiangsu, China

A total of 198 agricultural soil samples were collected from Zhangjiagang and Changshu in Southern Jiangsu for analysis of 13 polychlorinated biphenyls (PCBs) in order to assess the levels of pollution, sources, area distribution, and potential risk for the environment. All methods were rigorously tested and an adequate quality control was ensured. Only one site had no PCBs residues, and the highest total PCBs concentration in the surface soils was 32.83 ng/g. The average concentration in all the soil samples was 4.13 ng/g, signaling low-level pollution. Tetra-, penta-, and hexa-chlorinated biphenyls were dominant species in soil samples, accounting for more than 75% ofΣPCBs in the soil samples. PCB118 was the most abundant congener in all the samples. The PCB118 was about 20% ofΣPCBs. The soil organic matter content showed only a weak correlation with the levels of all PCB congeners, in which a better correlation was noted for the more volatile lighter PCB congeners than for the heavier homologues. To a certain extent, the sources and land use seemed to influence the levels of PCBs.
