Abstract:
This study was carried out to determine some physico-chemical
properties of different lakes and pond of metropolitan city, namely
Curzon Hall, Dhanrnondi, Hatirjhecl and Shcr-c-I3angla Agriculutral
University campus. Dhaka. Ten samples were collected from the each
pond and lakes to analyze the physico-chemical properties such as Color,
Odor. pH, Total Dissolved Solids (TDS), Salinity. Sodium (Na),
Potassium (K), Calcium (Ca), Carbonate (CO--,) and Bicarbonate (1 1CO3).
The odor of lakes water was slightly bad and the color was light grey to
slightly black. The results of the present study shows that except pu, K
and HCO3. other measured parameters did not exceed the maximum
permissible limit. The p1! exceeded (8.22) the standard limit (>8) for
other three lakes except Hatirjheel lake. The K content exceeded the
acceptable limit (<Smg/L.) except SAU campus pond. And Bicarbonate
was found within ranges of 244 to 400mg!1. for all the pond and lakes,
whereas the standard limit of Bicarbonate is 1.50mg/L. From the
statistical point of view, most of time, pH and Bicarbonate showed
negative correlation with other parameters. So, it can be concluded that
without proper analysis of the water quality of different lakes and pond of
Dhaka city shoutd not use for drinking purposes, agricultural productions,
fisheries, livestocks, recreational activities and various industrial uses.
