Article Synopsis
- A two-year study was conducted in Qingdao from November 2018 to January 2020 to analyze trace elements in atmospheric particulate matter (PM) during autumn and winter, focusing on their sources and health risks.
- The research identified four air quality levels and revealed that concentrations of trace elements, particularly vanadium (V), decreased significantly due to the implementation of the Domestic Emission Control Area (DECA) policy aimed at reducing pollution from ships.
- Health risk assessments indicated varying levels of non-carcinogenic and carcinogenic risks associated with elements like manganese (Mn), arsenic (As), and cadmium (Cd), highlighting the need for better pollution management strategies.
Wet flue gas desulphurization (WFGD) is wildly used to control SO emission from coal-fired power plants. The influence of WFGD on particulate matter (PM) emission has recently drawn significant public attentions in China. In this study, PM was collected at both the inlet and outlet from three WFGD units, including a single scrubber lime-stone-gypsum FGD unit, a cascade scrubber lime-stone-gypsum FGD unit, and a seawater FGD unit.

It includes the esmission of PM and PM from stationary sources. However, there is no national standard method in China for stationary source PM and PM sampling.
