How did I get cadmium poisoning?
Cadmium exposure occurs from ingestion of contaminated food (e.g., crustaceans, organ meats, leafy vegetables, rice from certain areas of Japan and China) or water (either from old Zn/Cd sealed water pipes or industrial pollution) and can produce long-term health effects.
Does dark chocolate have cadmium in it?

How can you tell if jewelry is cadmium?
There is no simple way to tell if jewelry contains cadmium or not just by looking at it.

Which disease is caused by cadmium?
Itai-itai disease is caused by cadmium (Cd) exposure, produced as a result of human activities related to industrialisation, and this condition was first recognised in Japan in the 1960s. Itai-itai disease is characterised by osteomalaecia with severe bone pain and is associated with renal tubular dysfunction.
Is cadmium magnetic yes or no?

How long does cadmium stay in the body?
Due to slow excretion, cadmium accumulates in the body over a lifetime and its biologic half life may be up to 38 years.
How do you clean up cadmium?
The OSHA cadmium standard requires that all surfaces shall be maintained as free as practicable of accumulations of cadmium. Proper clean-up of accumulated dust must be accomplished by wet cleaning or using a dedicated HEPA-vacuum: not by sweeping (wet or dry), shoveling or brushing.
