Mercury toxicity has been linked to, among other things, mercury dental fillings, particularly when people have a large number of them. Symptoms include a metallic taste in the mouth, excess salivation, gingivitis, tremors, stomach and kidney troubles. It also causes abdominal pain and hemolysis.

Signs and symptoms of lead toxicity include combinations of gastrointestinal complaints, hypertension, fatigue, hemolytic anemia, abdominal pain, nausea, constipation, weight loss, peripheral neuropathy, cognitive dysfunction, arthralgias, headache, weakness, convulsions, irritability, impotence, loss of libido, depression, depression of thyroid and adrenal function, chronic renal failure, gout.

Inorganic arsenic accumulates in the liver, spleen, kidneys, lungs, and gastrointestinal tract. It then passes through these sites but leaves a residue in tissues such as skin, hair, and nails. Symptoms of acute inorganic arsenic poisoning include severe burning of the mouth and throat, abdominal pain, nausea, vomiting, diarrhea, low blood pressure (hypotension), and muscle spasms.

Individuals with cadmium poisoning may also experience improper functioning of the canals with the kidney (renal tubular dysfunction) characterized by excretion of abnormally high levels of protein in the urine (proteinuria), minor changes in liver function, and/or softening of certain bones (osteomalacia).
