Summary of 239 days field survey from August 1995 to February, 2000

27 days detailed field survey information from April 1999 to February, 2000

Summary of 27 days field summary

After doing our field survey from August 1995 to March 1999 in Bangladesh, we realised that even after working for 212 days we had seen only the tip of iceberg. Every time we went on our field visit, we came up with more information about new affected villages and police stations. From April 1999, we planned to survey for 30 days to check out all the new information we had about the affected districts, Police Stations and villages. Finally we ended if with 27 days field survey from April 1999 to February 2000.

Round the year field survey is difficult in Bangladesh because of its climate. In a year, one can do field survey continuously only from middle of September to April. Sometimes, even that is not possible - for example when the whole of Bangladesh remained submerged under flood waters for 4 months in 1998 (July - October).

Our 27 days field survey was in this order

April 13 ,1999 =   1 day
April 15 - 19 , 1999 =   5 days
September 30 to October 5 , 1999 =   6 days
December 22 to January 1, 2000 = 11 days
February 10 to February 13, 2000 =   4 days
Total
= 27 days

Table-5: Shows the districts, police stations and villages we covered during 27 days field visit (All villages reported here are surveyed for the 1st time during 27 days field visit).

Table-6: New districts, Police Stations and villages found during our 27 days field survey .

Table-7: Shows the total water samples collected during our 27 days field visit and distribution of total samples in different arsenic concentration (µg/l) range. It appears from the table that 81.6% of the samples have arsenic concentration above WHO guidelines value and 56.66% above maximum permissible limit.

Table-8: Shows the total population we had examined and % of the people having arsenical skin lesions (adult male, adult female and children).

Table-9: Shows the arsenic analysis of hair, nail, some urine and skin-scales from the people of affected villages. Almost 50% of the samples (except skin scales) are from people having arsenical skin lesions and rest 50% from the people of some affected villages but have no skin lesions.
