Abstract
In the present study Pesticides, Arsenic and Nitrate contents were analyzed in the ground water samples collected from the different
districts of Sindh. Endosulfan was found above the MAC level (Maximum Acceptable Concentration 0.1 µg L-1
for single pesticide)
and chlorpyrifos was found below the MAC level as defined by the Economic European Countries (EEC). Nitrate and arsenic contents
were below the National Environmental Quality Standard (NESQS) i.e., 50 mg L-1
and 10 µg L-1
, respectively. A highly significant
correlation of endosulfan with arsenic (r = 0.94) and nitrate (r = 0.95) was recorded followed by moderate correlation of nitrate with
arsenic (r = 0.52), chlorpyrifos (r = 0.51). Correlation and between arsenic and chlorpyrifos was also significant (r = 0.50)
