The Effect of PM2.5 Exposure on Workers’ Enzymatic Superoxide Dismutase (SOD) Concentration at a Ready-Mix Concrete Factory in 2018

The lungs are exposed to PM2.5 via inhalation; PM2.5 then settles in the alveoli and circulates via the blood system, causing chronic obstructive pulmonary disease and cardiovascular issues. PM2.5 triggers the formation of superoxide anions and provide signals for the formation of superoxide dismutase. Workers at ready-mix concrete factories had long-term exposure to high doses of PM2.5. This study investigates the effects of PM2.5 on the blood SOD concentration of workers.
