with particular reference to the river Indus starting from Layyah to Mithan kot. Certain
physico-chemical parameters including light penetration (20-205 mm), suspended solids
(0.6-3.4 g l1), alkalinity (90-193 mg l1), total dissolved solids (150-245 mg l1),
electric conductivity (300-490 mhos), total volatile solids (0.01-0.052 g l1), dissolved
oxygen (7.4-17.4 mg l1) and pH (7.6-8.52) were taken into account from Layyah,
Taunsa Barrage and Mithan kot. Study results revealed that area is subjected to immense
erosion pressure exerted by the local hill torrents coupled with influx of upland pollution
and Himalayan watershed erosion. It further resulted in enhanced turbidity level that is
detrimental to the very survival of endangered Indus Dolphin (Platanista minor), certain
local fish fauna, aquatic plants and other biotic life forms of the river ecosystem.]]>Rafique, M.,20003232332Seehausen, O., J.J.M. van Alphen and F. White,199727718081811Ahmad, N. and S.D.
