comparing the weight of the liver to that of the fishes’
total weight, it was revealed that the weight of the
liver was reducing faster compared to that of the
fishes’ body weight. So the hepatosomatic index was
reducing with increase in concentration of Butachlor
as shown in Figure 3. Similar observations were seen
in fish exposed to Atraxine as expressed in Figure 4.
Similar relationships were observed in the gonads of
the fish exposed to these xenobiotics. These are shown
in Figures 5, Figure 6, Figure 7 and Figure 8 for
Gramoxone, Glyphosaye, Butachlor and Atrazine
respectively.
