Influence of the experimental conditions on manganese bioaccessibility and oxidative potential of welding fumes

When inhaled, particulate Mn is known to catalyze the reactive oxygen species (ROS) production. ROS can react quickly with lung fluids and epithelial cells causing their damage. A previous study showed that Mn and Cu from welding fumes (WF) were highly soluble in phosphate buffer (PB) and the main contributors to the oxidative potential (OP) of WF extracts (Ghanem et al., 2021). To estimate the potential health effects on exposed workers, analysis may be carried out to assess the contribution of Mn bioaccessibility on the OP of WF.
