Percent reduction in HDI due to arsenic pollution is shown
in Figs. 8 to 13 for all the 6 blocks analyzed. The highest percent
reduction in HDI in block Langola was in the range of 20 to
25% (Fig. 8) though the areal coverage of this was negligible and
the corresponding arsenic content was in the range of 0.30 to
0.35 mg/L.
