· E10(Effluent 10%)­An initial decline <strong>of</strong> 82.72 % compared from normal is shown in
Alkpase in the first 48 hours, followed by a steep rise <strong>of</strong> 126% in 96 hours and drastically
declining by 70.48% in 160 hours.
· E20(Effluent 20%)­Shows an initial % decline <strong>of</strong> 80.34in 48 hours followed by a % hike
<strong>of</strong> 28.46 in 96 hours and 93.33 in 160 hours.
· E30(Effluent 30%)­ Shows an initial % decline <strong>of</strong> 65.17 in 48 hours followed by a
gradual decline by 71.54% in 96 hours , subsequently rising back to normal(100%) in
160 hours.
<strong>Effect</strong> <strong>of</strong> <strong>effluent</strong> concentration on ALP <strong>of</strong> gill was found statistically non significant by
ANOVA. However, duration <strong>of</strong> exposure (F=5.16; P
