The research aimed to evaluate the gas pollutant emission in a relatively closed and stable environment, specifically in the Geelong area on Corio Bay, Victoria state, Australia, under the circumstances of the global respiratory epidemic. During this pandemic, owing to the small local population and a limited number of travelers, industrial emissions have become the only vital factor to interfere with air quality, excluding the impact of ordinary daily traffic. PM10 (ug/m3) data were measured every hour by the Victorian Government, uninterruptedly from 2017 January 1st to 2020 December 31th. The emission of industrial waste gas and the leakage of fossil oil jointly determine local air conditions, which can be reflected in the numerical value of the PM10 in the Geelong area. Sample data of PM10 were analyzed through the US EPA Positive Matrix Factorization model (PMF 5.0) to show the tested factor and contribution output. The results demonstrate the actual air condition in a local environment, which reflects the impact of regional factories on the environment. In addition, the model result will be compared to the annals data to testify its accuracy and precision; moreover, it will forecast the next year's air condition, which is of practical significance for treatment of waste gas emissions from factories and for the development of environmental protection.
