Lead Concentration in Renal Stones

Lead concentration for each group is shown in Table 1 which also shows mean Pb concen-trations called "Low Pb cone." calculated for groups with patients who had been exposed to environmental pollution. It is shown that Pb concentration strongly depends on chemical com-position of the stones.

Air Quality - Lead - Environment

Lead (or Pb in the periodic table) is a naturally occurring heavy metal that is found in the Earth’s crust. Lead can be released into soil, air and water through soil erosion, volcanic eruptions, sea spray and bushfires. The natural concentration of lead in the air is less than 0.1 microgram per cubic metre.

Lead glass - Wikipedia

Lead glass, commonly called crystal, is a variety of glass in which lead replaces the calcium content of a typical potash glass. Lead glass contains typically 18–40% (by weight) lead(II) oxide (PbO), while modern lead crystal, historically also known as flint glass due to the original silica source, contains a minimum of 24% PbO. Lead glass is often desirable for a variety of uses due to its ...

voltages dependent upon the lead concentration. Other voltage measurements can be devised based upon the chelation of aqueous lead to a nonaqueous carrier in which lead is partially transported into a membrane. The voltage across the membrane, just as the voltage across a cell membrane, will be altered by the extent of lead transport.
