Where It Comes From
Natural in ores; released during mining, smelting, and refining (especially of copper/lead). Used in semiconductors/thermoelectrics, solar cells, rubber processing, and glass/ceramics [1].
How You Are Exposed
Breathing dust or fumes at work; swallowing contaminated food or water near smelters or waste sites; much lower exposure for the general public. Skin contact with powders is possible but less common [1][2].
Why It Matters
Symptoms can include metallic taste, dry mouth, nausea, vomiting, headache, fatigue, and a strong garlic‑like odor from breath/sweat. Higher exposures can cause nerve problems; liver and kidney effects have been reported. Not currently classified as a carcinogen by major agencies [1][2].
Who Is at Risk
Workers in mining/smelting/refining, electronics/semiconductors and CdTe solar manufacturing, rubber/glass production, and e‑waste recycling; family members via take‑home dust [1][2].
How to Lower Your Exposure
Use ventilation and PPE; avoid creating dust/fumes; wash hands, change clothes, and launder workwear separately; follow employer/NIOSH/OSHA guidance; check local advisories near smelters; tell your clinician if you notice garlic‑like odor after exposure [1][2].
