Our field survey

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.
