Solubility of fume particulates generated by RVSS and HVSS welding. RVSS and HVSS fume particulates were collected on to PVC filters (n = 4 for each fume type). The particulates were suspended in distilled water, sonicated and centrifuged to obtain insoluble (pellet) and soluble (supernatant) fractions. The pellet and supernatant were subject to elemental analysis by ICP-AES following the NIOSH method 7300 to determine the elemental composition of the insoluble and soluble fractions. Fe, Mn, Ni and Cu made up the major composition (>99%) of the two fractions. The concentration of each element was calculated as μg/mg total metal. Graphical representations are Mean ± SE (n = 4/group). # indicates significantly different from RVSS group.
