Murshidabad district

The area and population of Murshidabad district are 5324 sq.km and 5.3 million respectively. We have been surveying all 26 blocks of Murshidabad for the last 3 years and have analyzed 29612 water samples for arsenic. The arsenic content in groundwater in 24 of the 26 blocks exceeds the 50 µg/l limit and in 25 blocks
above 10 µg/l (Figure 3). Our calculation reveals that at least 1.2 million people in these 24 blocks are drinking water whose arsenic content exceeds the maximum permissible limit set by WHO. Till date, we have succeeded in partially ascertaining the number of patients in 3 blocks of the districts. We have recorded the names, addresses and description of the arsenical skin lesions of about 4813 patients. Detailed field survey of Murshidabad district is given in Table 3.

During our very preliminary 4 days survey from 18-21 December, 2001 from 4 affected blocks of Murshidabad we have registered 931 new patients with arsenical skin lesions and out of them 14 are suspected cancer patients and 72 suspected Bowens (Photograph 2-6). Our experience in the field as well as inputs given by the villagers have pointed out that we have not succeeded in recording the problems of even 10% of the suffering / affected folk. One of the reasons, during the time we are in the village, most of the adult villagers is in the field and school going folk are in schools. We also feel that affected young girls and middle-aged women did not turn up to our camp to avoid social problem. We have learned from the affected villagers that one or two members of many families had arsenic marks on their skins and had met with untimely death. A considerable number of people who have died of cancer also had arsenic lesions.
The arsenic affected villages are home to many types of problems. Young men and especially women are encountering serious difficulty in getting married because of the arsenic mark on their skins. Even persons with arsenic skin lesions are being refused jobs. Some patients are being isolated because of

the mistaken notion of the lesions being leprosy. Even married women are being sent back to their parents because of lesions.
