| 1 | Decentralized wastewater treatment technologies and management in Chinese villages显示文摘在中国在农村区域对待污水的问题在最近的年里吸引了增加的注意。然而,仅仅,有的 6% 农村区域在 2010 底喷洒排水和废水处理系统。估计当前使用的技术是必要的以便在农村区域的污水处理能适当地被开发,到提供可靠、买得起的废水处理,在这些区域。我们评估了在各一直在操作至少一年了的 62 台设备上进行案例研究当前在农村区域使用的污水处理技术。我们的学习在 2009 和 2011 之间被执行,并且目的是在那经期期间估计状况并且估计在村庄里涉及分散的污水治疗的任何问题。我们发现那个分散的污水处理是村庄里的最流行的废水处理方法,并且最普通的主要处理技术在农村区域使用了,这是化粪池。我们的调查加亮需要为估计自河质量建立标准,包括目标污染物质的一个范围。我们的结果也证明自河应该被再使用在不同区域满足本地环境要求,特别在生态地敏感的区域。 | Xuesong GUO Zehang LIU Meixue CHEN Junxin LIU Min YANG | 2014 | Frontiers of Environmental Science & Engineering2014，8，6： | 13 |
| 2 | Geographic distribution and prevalence of human echinococcosis at the township level in the Tibet Autonomous Region显示文摘Background Echinococcosis,a zoonotic parasitic disease,is caused by larval stages of cestodes in the Echinococcus genus.Echinococcosis is highly prevalent in ten provinces/autonomous regions of western and northern China.In 2016,an epidemiological survey of Tibet Autonomous Region(TAR)revealed that the prevalence of human echinococcosis was 1.66%,which was much higher than the average prevalence in China(0.24%).Therefore,to improve on the current prevention and control measures,it is important to understand the prevalence and spatial distribution characteristics of human echinococcosis at the township level in TAR.Methods Data for echinococcosis cases in 2018 were obtained from the annual report system of echinococcosis of Tibet Center for Disease Control and Prevention.Diagnosis had been performed via B-ultrasonography.The epidemic status of echinococcosis in all townships in TAR was classified according to the relevant standards of population prevalence indices as defined in the national technical plan for echinococcosis control.Spatial scan statistics were performed to establish the geographical townships that were most at risk of echinococcosis.Results In 2018,a total of 16,009 echinococcosis cases,whose prevalence was 0.53%,were recorded in 74 endemic counties in TAR.Based on the order of the epidemic degree,all the 692 townships were classified from high to low degrees.Among them,127 townships had prevalence rates≥1%.The high prevalence of human echinococcosis in TAR,which is associated with a wide geographic distribution,is a medical concern.Approximately 94.65%of the villages and towns reported echinococcosis cases.According to spatial distribution analysis,the prevalence of human echinococcosis was found to be clustered,with the specific clustering areas being identified.The cystic echinococcosis primary cluster covered 88 townships,while that of alveolar echinococcosis’s covered 38 townships.Conclusions This study shows spatial distributions of echinococcosis with different epidemic degrees in 692 townships of TAR and high-risk cluster areas at the township level.Our findings indicate that strengthening the echinococcosis prevention and control strategies in TAR should directed at townships with a high prevalence and high-risk clustering areas. | Liying Wang Gongsang Quzhen Min Qin Zehang Liu Huasheng Pang Roger Frutos Laurent Gavotte | 2022 | Infectious Diseases of Poverty2022，11，1： | 1 |
