Industry Group Profile - Lead Exposure. Inorganic lead is a malleable, blue-gray, heavy metal that occurs naturally in the Earthâs crust. Lead was one of the first metals used by humans and consequently, the cause of the first recorded occupational disease (lead colic in a 4th century BC metal worker). In 2012, U.S. production of lead was estimated at 1.6 million metric tons; primarily from secondary refining of scrap metal.
In adults, exposure to lead may be short-term or chronic. Repeated or chronic exposure can cause lead to accumulate in your body, leading to lead poisoning. Lead poisoning can cause metallic taste, poor appetite, weight loss, colic, upset stomach, nausea, vomiting, and muscle cramps. Short-term exposure to lead can irritate the eyes on contact and cause high blood pressure, headache, irritability, reduced memory, disturbed sleep, and mood and personality changes.
