Скачать или смотреть Sources of Cadmium Poisoning; Occupational Exposure, Lifestyle Exposure, Dietary Sources

Cadmium Poisoning occurs when toxic levels of cadmium—a heavy metal used in various industrial processes—accumulate in the body. It can affect the kidneys, bones, and lungs, and is classified as a human carcinogen. Here's a breakdown of the main sources of cadmium exposure that lead to environmental and health risks:

🏭 Industrial Sources
Mining and Smelting: Cadmium is released during the extraction and processing of zinc, lead, and copper ores2.

Battery Manufacturing: Especially nickel-cadmium (NiCd) rechargeable batteries, which are still used in some electronics.

Electroplating and Soldering: Workers may inhale cadmium fumes during metal finishing and welding.

Pigments and Paints: Cadmium compounds are used in bright red, yellow, and orange paints—spraying or scraping these can release toxic dust.

🚬 Lifestyle and Consumer Products
Cigarette Smoke: Tobacco plants absorb cadmium from soil; smokers inhale cadmium directly, doubling their body burden compared to non-smokers.

Contaminated Food: Cadmium enters the food chain via polluted soil and water. High-risk foods include:

Shellfish and organ meats

Rice and cereal grains

Mushrooms and potatoes

Dark chocolate

🌍 Environmental Contamination
Industrial Wastewater: Improper disposal contaminates rivers and groundwater.

Hazardous Waste Sites: Leaching from landfills and e-waste dumps can pollute nearby soil and crops.

Air Pollution: Urban areas near factories may have elevated cadmium levels in ambient air.

🧪 Exposure Routes
Route Common Contexts
Inhalation Industrial fumes, cigarette smoke
Ingestion Contaminated food, water, or dust
Dermal Less common, but possible with cadmium-containing products
