Lead

Lead can damage the central nervous system, cardiovascular system, reproductive system, hematological system, and kidneys. It can be toxic when absorbed into the body in high doses.

Lead is most commonly absorbed into the body by inhalation. When workers breathe in lead as a dust, fume, or mist, their lungs and upper respiratory tracts absorb it into the body. Once in the bloodstream, lead circulates through the body and is stored in various organs and body tissues.

Symptoms of chronic exposure include loss of appetite, constipation, nausea, fatigue, headaches, tremors, weakness, metallic taste, abdominal pain, muscle or joint pain, insomnia, numbness, dizziness, and anxiety.

In general industry, lead is used in the manufacture of batteries, metal products, and ammunition. Exposure can occur from breathing contaminated air in or near workplaces that process lead or lead materials, as well as from accidentally ingesting dusts or paint chips in places with lead-based paint.
