A clean, safe living environment is necessary for people to be happy. However, because of a lack of awareness regarding the influences of pollution, air contaminants are not intuitively understood. Once the understanding of air pollutants among city residents is improved, the dissemination of information is easily accomplished. Environmental studies have been conducted in several major Asian cities to evaluate the influence of pollution on global weather conditions, and the results have been made public. This paper reports on Melbourne, in order to facilitate comparison with cities in Asia. Melbourne, located in southeastern Australia, is not influenced by the air pollution of the northern hemisphere because it is located south of the "chemical equator." Moreover, since Melbourne is not prone to haze, the air is not polluted and its environment is known to be excellent. The researcher visited Melbourne in August 2013 and February 2014. Measurements of suspended particulate matter(SPM)were logged in the center of the city and measured in areas within a 20 km range. The values in both winter and summer were extremely low, and their mean values were much lower than the background value of Shanghai. This interesting result warrants further discussion in the context of the metropolitan environment of Asian countries.
