ABSTRACT

Basic information on depth of bore wells, periods of their use, and pH values of the irrigation bore well water samples collected at source were obtained from the field and tested for As content by standard SDDC method (APHA 1989). Upon laboratory confirmation of presence of As in irrigation water, soil and rice plant samples from selected As hotspots, pot experiments were undertaken on six locally produced rice varieties (PNR-381, Turantha, Saroj, Sugandha, Sarna and Katarni). Thereafter, water, soil and plant samples, collected from the field and of the pot experiments, were tested for As content.
