Heavy Metal Poisoning NORD (National Organization for

Heavy metal poisoning is the accumulation of heavy metals, in toxic amounts, in the soft tissues of the body. Symptoms and physical findings associated with heavy metal poisoning vary according to the metal accumulated. Many of the heavy metals, such as zinc, copper, chromium, iron and manganese, are essential to body function in very small

Supplier of Bismuth Metal SMI Inc. Minor Metals

Bismuth is a heavy, brittle metal that is primarily used in low-melt alloys. Extracted as a by-product of lead, tin, silver and copper, bismuth has a low thermal conductivity and is both stable and non-toxic. These properties make the metal an ideal substitute for lead in everything from pipes and bullets to fishing weights and sprinkler triggers.
