[Variation Characteristics and Source Analysis of Carbonaceous Aerosols in Winter in Jiashan].

Organic carbon (OC), elemental carbon (EC), and PM concentration data obtained from Shanxi Super Station in Jiashan County of Jiaxing City, in the winter of 2018 and 2019, were analyzed to determine the variation and potential source areas of carbonaceous aerosols. The results show that OC concentrations in the winter of 2018 and 2019 were 6.90 μg·m and 5.
