Physicochemical properties, such as particle sizes, composition, and solubility of welding fumes are decisive for the bioaccessibility of manganese and thereby for the manganese cytotoxic and neurotoxic effects arising from various welding fumes. Because of the diverse results within the research on welding fume solubility, this article aims to review and discuss recent literature on physicochemical properties of gas metal arc welding, shielded metal arc welding, and flux-cored arc welding…

Welding fume nanoparticles from solid and flux-cored wires: Solubility, toxicity, and role of fluorides.
Physicochemical properties of air discharge-generated manganese oxide nanoparticles: Comparison to welding fumes.
TLDR
The size, morphology and Mn oxidation states of Mn oxide nanoparticles generated in the laboratory by arc discharge to those from welding collected in heavy vehicle manufacturing are compared and suggest several important considerations for understanding the health effects of welding fumes.
Size-separated particle fractions of stainless steel welding fume particles - A multi-analytical characterization focusing on surface oxide speciation and release of hexavalent chromium.
Manganese speciation of laboratory-generated welding fumes.
TLDR
Although the concentration of Mn measured from summation of the four sequential steps was statistically significantly different from that measured from the hot block dissolution method for total Mn, the difference is small enough to be of no practical importance for industrial hygiene air samples and either method may be used for Mn measurement.
High variability in toxicity of welding fume nanoparticles from stainless steel in lung cells and reporter cell lines: the role of particle reactivity and solubility
TLDR
Interestingly, the FCW fume particles were the most soluble in PBS, releasing more chromium in the hexavalent form and manganese compared to the other fumes, emphasizing the importance of solubility of different metal constituents of the fumes particles, rather than the total metal content, for their acute toxic potential.

TLDR
This study shows that a welding fume exposure control and management program is warranted, especially for welding jobs in confined spaces, as exposures to different Mn fractions using a sequential extraction procedure were evaluated.

Effect of welding fume solubility on lung macrophage viability and function in vitro.
TLDR
Data show that differences in the solubility of welding fumes influence the viability and ROS production of macrophages and the presence of soluble metals, such as Fe, Cr, Ni, Cu, and Mn, and the complexes formed by these different metals are likely important in the pulmonary responses observed after welding fume exposure.
