What is arsenic?

Arsenic exists in different chemical forms, which can be classified into two groups: organic arsenic and inorganic arsenic. Inorganic arsenic is considered to be the most toxic to human health, while most of organic arsenic is considered to be non-toxic.

What health effects are related to inorganic arsenic levels?

After ingesting high levels of inorganic arsenic, individuals may experience: irritation of the stomach and intestines, with symptoms such as pain, nausea, vomiting and diarrhea. Other possible effects are decreased production of red and white blood cells, abnormal heart rhythm, blood vessel damage and impaired nerve function causing a “pins and needles” sensation in your hand and feet.

Health Canada considers arsenic as a human cancer-causing agent if consuming or drinking very high concentrations of arsenic over a lifetime. Arsenic at the levels that are normally found in drinking water and soils is not considered to be immediately toxic.
