“…The low PB solubility observed for Fe (<1%) was in agreement with what has been reported in other publications dealing with WF [11,28,81,84] which classified Fe as the least soluble element. These publications suggest that Fe in WF is not in the form of soluble salts but mainly in the form of oxides (hematite) or in metal phases of low solubility.…”

“…Relative metal PB solubility (Fe < Cr-Ni < Zn-Cu-Mn) shows a similar trend to those found by Berlinger et al [81], who studied the Hatch solubility of WF (collected in shipyards and in a factory producing heavy machinery). The conditions of the Hatch protocol are given in Table A6 in Appendix A.…”

“…In addition, in simulated physiologic media at pH = 7.4 such as PB, Gamble, or Hatch solutions, Fe can form iron hydroxides which are also poorly soluble. On the contrary, for Mn and Cu, a larger fraction was probably present as soluble compounds [81]. Cu can be present as more soluble compounds in MSWF-1 (11%) than in SSWF-1 (6%), but inversely, Mn has a lower PB solubility in MSWF-1 (3.4%) than in SSWF-1 (9%).…”

To evaluate the chemical behavior and the health impact of welding fumes (WF), a complex and heterogeneous mixture of particulate metal oxides, two certified reference materials (CRMs) were tested: mild steel WF (MSWF-1) and stainless steel WF (SSWF-1). We determined their total chemical composition, their solubility, and their oxidative potential in a phosphate buffer (PB) solution under physiological conditions (pH 7.4 and 37 °C). The oxidative potential (OPDTT) of WF CRMs was evaluated using an acellular method by following the dithiothreitol (DTT) consumption rate (µmol DTT L−1 min−1). Pure metal salts present in the PB soluble fraction of the WF CRMs were tested individually at equivalent molarity to estimate their specific contribution to the total OPDTT. The metal composition of MSWF-1 consisted mainly of Fe, Zn, Mn, and Cu and the SSWF-1 composition consisted mainly of Fe, Mn, Cr, Ni, Cu, and Zn, in diminishing order. The metal PB solubility decreased from Cu (11%) to Fe (approximately 0.2%) for MSWF-1 and from Mn (9%) to Fe (<1%) for SSWF-1. The total OPDTT of SSWF-1 is 2.2 times the OPDTT of MSWF-1 due to the difference in oxidative capacity of soluble transition metals. Cu (II) and Mn (II) are the most sensitive towards DTT while Cr (VI), Fe (III), and Zn (II) are barely reactive, even at higher concentrations. The OPDTT measured for both WF CRMs extracts compare well with simulated extracts containing the main metals at their respective PB-soluble concentrations. The most soluble transition metals in the simulated extract, Mn (II) and Cu (II), were the main contributors to OPDTT in WF CRMs extracts. Mn (II), Cu (II), and Ni (II) might enhance the DTT oxidation by a redox catalytic reaction. However, summing the main individual soluble metal DTT response induces a large overestimation probably linked to modifications in the speciation of various metals when mixed. The complexation of metals with different ligands present in solution and the interaction between metals in the PB-soluble fraction are important phenomena that can influence OPDTT depletion and therefore the potential health effect of inhaled WF.

“…Where Gamble's solution contains citrate as a substitute for organic components, Hatch's solution incorporates proteins and enzymes in the mixture (Sysalova et al 2014). It has primarily been used in bioaccessibility studies of airborne particulates including welding fumes (Berlinger et al 2008;Ellingsen et al 2013Ellingsen et al , 2017Berlinger, Weinbruch et al 2019;Zadrapova et al 2019), urban particulate matter (Sysalova et al 2014) and airborne particulates from car batteries (Dartey et al 2014). When investigating the bioaccessibility of welding fumes, Hatch's solution was used alongside Gamble's solution, to evaluate the use of proteins and enzymes in the composition (Berlinger et al 2008).…”

“…Chemical composition of welding fumes depends on the welding technique used, welding parameters, melting, welding metal and welding electrode which has a composition of metal (Berlinger et al, 2019). When welding, welding fumes, gases and electromagnetic energy (radiation) are usually released in indoor areas.…”

En este estudio, la muestra de humo de soldadura se obtuvo a partir de aceros de bajo y medio carbono y los electrodos utilizados en la soldadura. Las microestructuras de las partículas se analizaron mediante microscopía electrónica de barrido (SEM), espectrómetro de dispersión de energía (EDS), difractómetro de rayos X (XRD) y espectrómetro de infrarrojos por transformada de Fourier (FTIR). En los experimentos se encontró que los elementos Be, O, F, Fe, Si, Cl, K, Ca, Ti, V, Cr, Mn tenían contenidos atómicos superiores al 1%. Con base en este hallazgo, se revela que la estructura está constituida principalmente por óxidos tipos Fe2O3, Fe3O4, MnO2, TiO2, SiO2, Fe3Mn3O8, FeMn2O4, BeO, CrO. También se encontró mediante análisis XRD que los elementos con contenidos inferiores al 1% atómico se encontraban también asociados a fases en forma de óxidos. Debido a que las estructuras oxidadas amenazan el medio ambiente y la salud humana, se ha descubierto experimentalmente que los metales emitidos por los humos de soldadura siguen contaminando y amenazando el medio ambiente.
