Sediment/Soil Concentrations: The principal form of lead from along roadsides is the sulfate salt(1). In a calcareous soil, PbSO4 and PbCO3 were shown to account for <5% of the total lead content, whereas in road side dust, PbSO4, elemental lead, Pb3O4, PbO.PbSO4 and 2PbCO3.Pb...
Silos are usually used to store bulk materials such as grains, coals and chemicals. Early silo designers believed that the pressure on the silo wall was linearly distributed in the direction of height, depending only on the height and density of the storage materials in the silo10,11. However...
