Ajaloomuuseumis Tallinnas asub K. Alates The trend of mean mineral concentration was significantly higher during the low than the high flow season at all the sites.
Water and sediment samples were collected from three lowly to highly polluted downstream sites Shahdera BSunder Cand Balloki D alongside the least polluted upstream site Siphon A during Juhtide ravi Baeri. and low river flow seasons.
All the mineral concentrations increased up to site C but stabilized at site D, showing some recovery as compared to the third sampling site. The trend of mean mineral concentration was significantly higher during the low than the high flow season at all the sites. The mean Hg concentrations approached 0. All mineral concentrations were much higher in the sediment than the water samples.
The domestic and industrial discharges from Lahore city have created undesirable water qualities during the low river flow season.
As majority of the mineral levels in the river Ravi were higher than the permissible and safe levels, this is of immediate concern for riverine fish consumers and the users of water for recreation and even irrigation. The use of these waters may pose health risks, and therefore, urgent intervention strategies are needed to minimize river water pollution and its impact on fish-consuming communities of this study area and beyond.
