Arsenic is also suspected to contribute to various other cardiovascular, pulmonary, immunological, neurological, peripheral vascular and endocrine diseases but as with the above symptoms, the epidemiological study of diseases caused by Arsenic poisoning is only in its infancy.

According to a news report April 19, 2001, a team of EPA scientists at EPA's Office of Research and Development laboratory in North Carolina have discovered a possible, direct link to DNA damage caused by arsenic compounds. The research demonstrates a human cell's own metabolic responses to arsenic exposure produce compounds that cause genetic damage.

A National Academy of Sciences (NAS) report says the US Environmental Protection Agency (EPA) has greatly underestimated the cancer risks of arsenic in drinking water, according to EPA officials, WaterTech online, 12 September 2001

Dr Azad of Hokkaido University in Japan has made the following classification of diseases caused by Arsenic in Bangladesh:

Initial Stage

Melanosis

Bronchitis
Gastroenteritis

Second Stage Depigmentation

Hyperkeratosis
Non-pitting edema of legs
Peripheral nephropathy

(In Bangladesh, the majority of patients are still at initial and second stages according to Dr Azad.)

Dr Azad also mentions the following additional conditions caused by Arsenic in drinking water, as reported from other countries.
