The SeAPM contains about 20% organic components and 80% inorganic matter (Soares et al., 2022). Inorganic matter contained a mixture of 27 metals at different concentrations of which Fe was the highest concentration followed by Al, Ti, Mn, and Zn. The elements Cu, Ce, Sr, Pb, Zr, Cr, La, V, B, Y, Sn, and Ni were at concentrations that varied from 50 to 10 µg g-1. Several trace elements (Rb, As, Nb, Se, W, Bi, Cd, Ba, Bi, Hg, and Ag) were lower than 5 µg g-1. Ta was detected, but not quantified. The addition of 1 g L-1 SeAPM into the water aquarium increased water conductivity as expected. Most of the SeAPM was deposited on the aquarium´s bottom. From those 27 metals quantified in the SeAPM, 19 were quantified dissolved in water. Ag, As, Ba, Bi, Cd, Hg, Se, and Sn quantified in the SeAPM were not detected (
