Abstract:
The main goal of this study is to compare concentrations of atmospheric Hg(p) for various particles sizes Total Suspended Particulates (TSP), PM18, PM10, PM2.5, PM1, PM<1 before (2018-2019) and during (2019-2020 and 2020-2021) COVID-19 occurred periods in central Taiwan. In addition, test the statistical differences concentrations of Hg(p) for various particles sizes before and during COVID-19 occurred periods in central Taiwan. Finally, calculate the Hg(p) health risk assessment before and during COVID-19 occurred period in central Taiwan.The result indicated that the mean Hg(p) concentrations in TSP and PM2.5 were higher during (2020-2021) the COVID-19 occurred period than that of the mean Hg(p) concentrations in TSP and PM2.5 before the COVID-19 occurred period. In addition, the Hg(p)concentrations PM18, PM10, PM2.5, PM1 and PM<1 were all increased during the COVID-19 occurred period. The Hg(p) concentrations in TSP were decreased during (2019-2020) the COVID-19 occurred period when compared with that of the before the COVID-19 occurred period. Moreover, significant mean Hg(p) concentrations differences were existed at PM18, PM10 and PM2.5 before and during (2020-2021) COVID-19 occurred periods. Finally, the HQ and HI values for Hg(p) were both increased during COVID-19 occurred periods when compared with before COVID-19 occurred period in this study.
