Abstract
Biological or Biochemical oxygen demand (BOD) indicates water pollution
status. BOD of a polluted municipal and a non-polluted village pond was
measured for six months from January 2024 to June 2024 in Suri I Development
block of Birbhum district. Higher BOD5 indicates polluted water of
municipality area pond and lower BOD5 indicates village pond water
is least polluted. Zooplankton density was found higher in non-polluted pond
and considerably lowers in polluted pond in the study period. Rotifer,
cladoceran and copepod zooplanktons were counted in the two study ponds. The t-value
(0.05 significance level; df-10) of zooplankton sample of two ponds was 4.387
which is higher than critical t-value of 2.228 indicating inverse impact of
water pollution on zooplankton abundance and density. There was found strong
negative correlation between BOD and zooplankton density in both ponds.
Zooplankton can serve as good bio indicator of water pollution.
