    Based on their locations on the periodic table, which best compares the properties of the metalloids arsenic (As) and antimony (Sb)? Arsenic has a more metallic behavior than antimony because arsenic’s atoms have fewer electron shells. Arsenic has a more metallic behavior than antimony because arsenic’s atoms have more electron shells. Several biologically antagonistic suites of metals (Cd, Cu, and V) were found in multiple PM size modes. Some of these metals showed erratic size distributions with daily changes in enrichment (e.g., Ni, Zn, Cd, As, and Cu) and particle size, suggesting a variety of emissions and metal exposure scenarios occurring in the near-highway by: Abstracts. To our astonishrr:ent, surprisingly Iittle research on metal leaching processes under environmental situations has been reported. Thus, the authors sumnarized the fundamental processes of metal sulfide leaching and subsequently applied, by inference and implication, this information to the mining of Cu-Ni ill the Duluth Gabbro. The present study was conducted to determine toxic metal concentration in fly ash and metal accumulation potential of the Saccharum munja and Cynodon dactylon, the two main grass species growing naturally on fly ash lagoon for Fe, Ni, Zn, Cu, Mn, Pb and Cd. Accumulation of metals were found in the order of Fe > Zn > Mn > Cu > Ni > Pb and by: 5.
