Lead (Pb)

Lead (Pb)

One of the oldest known metals, lead ([Xe]4f145d106s26p2) (CAS 7439-92-1) is bluish-white, lustrous, and soft. It is highly malleable, ductile, insoluble in water, and noncombustible. Lead is a poor electrical conductor and a very effective sound absorber. It is relatively impenetrable to radiation, making it an effective shield of X-ray equipment and nuclear reactors. Lead is very resistant to corrosion and is often used to contain corrosive liquids.

Lead Paint Inspection
Government regulations, such as the U.S. EPA-issued Renovation, Repair and Painting (RRP) Rule, have increased public awareness of the need for lead paint testing. Lead poisoning is a well-known health threat to children, but lead exposure can cause serious issues for adults as well, including high...
Forensic Microscopy
Electron microscopy (EM) has a wide variety of applications in forensic investigation. Numerous crime-scene micro-traces, including glass and paint fragments, tool marks, drugs, explosives and gunshot residue (GSR) can be visually and chemically analyzed with scanning electron microscopy (SEM) .
