Summary
of 239 days field survey from August 1995 to February, 2000
27
days detailed field survey information from April 1999 to February, 2000
Total number of days
surveyed: 239 (Two hundred thirty nine) days
239 days field study at a glance (August
1995 to February 2000)
Our field survey classified in
2 categories
Study-1: Water
collection for arsenic and iron analyses and only identification of
villages
where people with arsenical skin lesions exist.
Study-2: Water,
hair, nail, urine, skin-scale collection and clinical examination
by medical
team in affected villages.
Normally, for Study-2
we had a total of 8 people in our field survey team. Among them two were
medical people, a biochemist, one analytical chemist, environmentalist
and experienced field workers. We usually began our field survey early
in the morning and left the field only after sunset. We worked till late
night to put the collected samples in order and to prepare for the next
day. With our long experience of working in the affected areas of West
Bengal, we have acquired the basic expertise in fieldwork. During our
survey we faced many difficult situations, but by now we know how face
and deal with agitated, frustrated villagers suffering from arsenic toxicity.

Firure-1: Shows
the number of districts contains arsenic below 0.01 µg/l, between 0.01
µg/l and 0.05 µg/l, and above 0.05 µg/l.
Figure-2: Shows the districts
from where we have so far identified people with arsenical skin lesions.
Table-1: Shows our water analysis
report of 22003 hand tube-wells from 64 districts of Bangladesh during
August 1995 to February 2000
Table-2: Shows water analysis
report of 20987 hand tube-wells from 47 districts so far we have identified
where groundwater contains arsenic above 0.05 µg/l
Table-3: Shows total villages
we examined from arsenic contaminated villages and total number of people
identified with arsenical skin lesions
