Because of the concerns arising from poor operation and management, siting and operation of landfill sites are very sensitive public issues in Nepal. The aim of this study was to assess the environmental impacts due to the foul odour during the operation of the the Sisdol landfill in Okharpauwa VDC, Nuwakot, Nepal. The study focused on identifying the composition of gases from the Kathmandu Valley's solid waste and impacts on local areas air flow moments from the land fill site. LandGEM Ver.3.02 Model was used for the emission calculation of the landfill gases. Furthermore, the gastec and specified ditector tubes were used for the measurement of H2S gas at the study area. Among nine sites, the H2S gas concentration at site (Vent pipe of landfill site) was 1.4 ppm (recorded maximum). The gas was found to be diluted at 208m downwind location and reached the value near to clean air, i.e., 0.2 ppb. The observed gas concentration was lower than the toxic range though the concentration level was found to have characteristic odour. The significant level of adverse impact was found nearby the landfill site. People working surrounding area of the landfill site were more vulnerable to different impacts.","PeriodicalId":72927,"journal":{"name":"Environment research journal","volume":"6 1","pages":"182-186"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70027512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper, by analyzing the data collected in Minqin desert area during the period of 1961-2009, attempts to figure out how the temperature, precipitation and air humidity in the desert area of northwestern China respond to global warming. The result revealed that: the increasing rate of the mean annual temperature in Minqin during 1961-2009 was greater than that of the global average and that of the hundred-year average in China; whereas lower than that in the arid area in northeastern China in the recent 20 years. In Minqin, the temperatures in winter and spring rose significantly. The winter and spring temperatures and the annual maximum temperature showed big variations, with great fluctuations. The annual air humidity increased dramatically while the precipitation displayed an insignificant increasing trend. There was a significant correlation between air humidity rising and precipitation increasing. However, there’s no sound consistency between the periodic variations of air humidity and those of precipitation. The warmer spring usually induced intensive sandstorms, and the instability of air temperatures has caused yield reduction of crops/ fruits in the study area.","PeriodicalId":72927,"journal":{"name":"Environment research journal","volume":"6 1","pages":"187-196"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70027589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
