An analysis of the local and regional effects on air quality in Shanghai, China from August 2003 to July 2004

Kwan, Stephanie Hoiyee 20 November 2006 (has links)
Effective management of air quality in Shanghai, China, requires an understanding of the emissions, chemistry, and local meteorology. The local and regional factors responsible for the spatial and temporal variations in NO2, SO2, and PM10 concentrations observed at 10 air quality monitoring sites in Shanghai from August 1, 2003 to July 31, 2004 were analyzed in intersite, interspecies, and species-meteorology correlations.

Development Of An Environmental Pollution Index For The Middle Section Of Seyhan Basin

Golge, Mehmet 01 May 2010 (has links) (PDF)
In this study, it is aimed to develop a database on Seyhan River Basin / and an environmental pollution index for the middle section of Seyhan Basin by combining different pollution indices such as water, and air. Water and air pollution indices are developed for the selected quality monitoring stations and the selected years. Water pollution index is calculated by using the method suggested by National Sanitation Foundation of United States, and air pollution index is developed according to the modified Environmental Protection Agency&rsquo / s air pollution index. As aggregation method, weighted arithmetic mean function is used for development of indices. After development of separate water and air pollution indices, environmental pollution index is developed for the year 2008 by two aggregation methods, one based on linguistic interpretation and the other again on weighted arithmetic mean function. The water pollution index for the middle section of the basin is determined as &ldquo / good&rdquo / , and air pollution index as &ldquo / low pollution&rdquo / . According to calculated water and air pollution indices, environmental pollution index is calculated with two methods and obtained the index equal to 4, which is classified as &ldquo / good&rdquo / . Although, both of the methods give same result in development of environmental pollution index, the second method based on weighted arithmetic mean function concluded to be more user friendly.
