EVALUATION OF OECD MEMBER COUNTRIES IN TERMS OF AIR POLLUTION THROUGH MULTIDIMENSIONAL SCALING ANALYSIS

Abstract

In the study, it is aimed to determine the location of the member countries of the Organization for Economic Cooperation and Development (OECD) in terms of air pollutants and to make evaluations. Multidimensional scaling (MDS) analysis was used to determine the locations of member countries of the OECD. In MDS, the groupings of objects, units, cases, etc. or the groupings of variables are tried to be determined according to the research variables. The variables of the study were carbon monoxide (CM), nitrogen oxide (NO), non-methane volatile organic compounds (NMVOC), particulates (PM2.5), particulates (PM10), sulfur dioxide (SO2), which were determined as the main anthropogenic air pollutants by the OECD formed the air pollutants. According to the study variables, with the MDS analysis in the two-dimensional coordinate system, OECD countries other than Turkey, Mexico, Canada and the USA were located very close to each other as the most similar countries. It has been determined that the air pollutant values of Turkey, Mexico, Canada and the USA are generally above the OECD average, but the CM value for Turkey is below the OECD average.
