5. Overview of river Chenab
■ Chenab River is one of natural resource of Pakistan. It starts from the Himalayas and
its length is 960 km.
■ The irrigation system of Pakistan is one of the best systems because 70% of the
cultivated area is under irrigation.Chenab river play important role in irrigation.
■ The Chenab River is generally considered the second healthiest river of Pakistan. It is
the source of income for many people.
■ As the water of Chenab river irrigates the lands of country the same way the fish,
prawns and other marine food is an important part of Pakistan’s economy.

10. Source of pollution in
River Chenab
 Industrial outfalls
 Agricultural runoff
 Urban runoff
 Ground fills
 Atmospheric deposition

11. Effect of pollution
on fishes
 viral infections
 bacterial infections, such as Pseudomonas
fluorescents leading to fin rot and fish
dropsy
 fungal infections
 water mold infections, such as Saprogenic
sp.
 metazoan parasites, such as copepods
 unicellular parasites, such as
Ichthyophthirius multifidi's leading to itch
 Certain parasites like Helminths for
example Stroggylis's

12. Harmful for Human
Consumption:
 Metal contents in fish muscles are most
important because these are consumed
constituents of human diet.
 Effluents discharged into streams contain
high load of heavy metals which are not
only threatening the ecological integrity of
aquatic recourses but also putting.

13. Exposure to high and
low concentrations of
toxicants may lead
rapidly to death or
interact with other
stressors, e.g. pathogens,
resulting in the
development of disease.

14. Remediation’s
■ Dilution: Dilution seems to be the most attractive method of waste disposal.
■ Appropriate technology: We should develop, import and adopt only appropriate
technology, which is pollution free.
■ Biological treatment: In biological treatment optimum conditions are provided for
natural self purification in lagoon with the help of trickling filters, activated sledge or
waste stabilizing ponds.
■ Efficient use (Reuse): Treatment of domestic sewage for industrial cooling is a good
example of efficient use. Water reuse has a special significance in mining and similar
industries where the resources are scarce.

15. Conclusions:
■ River Chenab is an important wetland of Punjab, Pakistan. Water is becoming polluted
due to anthropogenic impact i.e. Industrial waste, urbanization, agriculture
intensification and global warming.
■ Concentration of heavy metals (lead (Pb), cadmium (Cd), chromium (Cr), and copper
(Cu)) was determined in the liver, gills, kidneys, and muscles of eight edible fish species.
■ Fishes found in downstream zone have higher quantity of metals in their organs.
■ Metal contents in fish muscles are most important because these are consumed
constituents of human diet.
