Lead Oxide - an overview | ScienceDirect Topics

Divalent lead oxide has the formula PbO. Lead(II) oxide occurs in two polymorphs, red, having a tetragonal crystal structure and yellow, having an orthorhombic crystal structure. Both forms occur naturally as rare minerals. The red form is known as "Litharge" and the yellow form is .

Management of Nitrogen Fertilizer to Reduce Nitrous Oxide ...

Nitrous oxide (N 2 O) is an important greenhouse gas that contributes to climate change. Because it has a long atmospheric lifetime (over 100 years) and is about 300 times better at trapping heat than is carbon dioxide, even small emissions of N 2 O affect the climate. Nitrous oxide is .

Larger emissions of greenhouse gases lead to higher concentrations in the atmosphere. Greenhouse gas concentrations are measured in parts per million, parts per billion, and even parts per trillion. One part per million is equivalent to one drop of water diluted into about 13 gallons of liquid (roughly the fuel tank of a compact car).

The lead content on the skin surface of 10 lead-battery workers was measured by the method of skin stripping, and urinary lead content of rats was measured with epicutaneous application of four lead compounds: lead sulfate, lead oxide, lead powder, and lead stearate. There were significant amounts of lead on the 9th and 10th skin strippings of the dorsal hand and the back of lead workers.

The paper considers a case history for means of overcoming lead oxide emission during the production of oxides from metallic lead at a factory where there was an occupational health problem. Following a survey, modifications to the process were proposed, but it was decided that the cost of these would make the plant uneconomic and so closure was inevitable.
