Air Quality Lead

[toc] What is lead? 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 microgram per cubic metre. Humans have used lead in various applications for

Atomic absorption Spectroscopy

Atomic absorption analysis involves measuring the absorption of light by vaporized ground state atoms and relating the absorption to concentration. The incident light beam is attenuated by atomic vapor absorption according to Beer's law. The process of atomic absorption spectroscopy (AAS) involves two steps: 1. Atomization of the sample . 2.
