    Health Problems Caused by Lead. It does not matter if a person breathes-in, swallows, or absorbs lead particles, the health effects are the same; however, the body absorbs higher levels of lead when it is breathed-in. Within our bodies, lead is absorbed and stored in our bones, blood, and tissues.

    Abstract. Submicrometre, highly pure and dense PbO particles were synthesized by pyrolysis of a spray of a lead nitrate, Pb(NO 3) 2 solution generated by an ultrasonic transducer in a tubular-flow reactor at 300–800 °C and at various carrier gas flow rates. The produced particles were non-agglomerated, non-porous, and mainly tetragonal PbO above 500 °C.

    Oxygen in the air, assisted by the heat of the tumbling lead, reacts with the lead to produce lead oxide. During milling, the lead oxide that forms on the surface of the ingots and fine particles of un-oxidized lead are broken off, forming a fine dust that is removed from the mill by a circulating air stream.

    Zinc oxide particles are transported into a cooling duct and collected in a bag house. This indirect method was popularized by LeClaire (France) in 1844 and therefore is commonly known as the French process. Its product normally consists of agglomerated zinc oxide particles with an average size of 0.1 to a few micrometers.

    Liquid lead-bismuth eutectic (LBE) is an important candidate to become the primary coolant of future, generation IV, nuclear fast reactors and Accelerator Driven System (ADS) concepts.
