Arsenic
Information
Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals, usually in combination with sulfur and metals, but also as a pure elemental crystal. Arsenic is a metalloid. It has various allotropes, but only the gray form is important to industry.

The primary use of metallic arsenic is in alloys of lead (for example, in car batteries and ammunition). Arsenic is a common n-type dopant in semiconductor electronic devices, and the optoelectronic compound gallium arsenide is the second most commonly used semiconductor after doped silicon. Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides. These applications are declining, however.

Arsenic is an element widely distributed in earth’s crust, and in groundwater in many countries. Long-term intake of arsenic contaminated water leads to arsenic poisoning or arsenicosis, with cancer of skin, bladder, kidney or lung or diseases of skin (colour changes, and hard patches on palms and soles), or blood vessels of legs and feet. Fresh evidence indicates possible association between intake of contaminated water to onset of diabetes, hypertension and reproductive disorders.

In India, the states of West Bengal, Jharkhand, Bihar, Uttar Pradesh, Assam, Manipur and Chhattisgarh are reported to be most affected by arsenic contamination of groundwater above the permissible level. WHO’s provisional guideline value for arsenic in drinking water - 0.01 mg/l (10 μg/l) (Source: Guidelines for drinking water quality, 4th edition, WHO, 2011). Permissible limit of arsenic in India in absence of an alternative source - 0.05 mg/l (50 μg/l). (Source: Indian Standards for Drinking Water, second revision of IS 10500, 2004).

Interviews
We plan to do einterviews with MBBS doctors to understand 4 things
1) Tests or questions you ask in first few meetings
2) What it means in medical terms
3) What it means in non medical terms
4) What should the patient or care takers do

We might interview Aurvedic doctors, homeopathic doctors, Yoga teachers on this health issue
