Environmental Safety of Vecor Tiles
By Dr. Erik Severin,
Director of Technology, Vecor Limited
USA EPA regulated metals with their concentration limits
Additional metals were investigated to ensure that nothing else leaches from our materials. The whole list of metals tested is shown in Table 2, along with the detection limits for each metal for the ICP spectroscopic equipment used.
Additional metals tested, with the limit of detection by ICP.
*Barium’s test result was 0.3 mg/L (300 ppb) which was greater than the ICP limit-of-detection, but still well below the allowed limit by the EPA, which is 100 mg/L (100 ppm). See Table 1 for reference.
