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 shipyards, lead is generally used in paints and other coatings. Lead-based paint is banned in residences, but it is still used on bridges, railways, ships, lighthouses, and other steel structures.
