Environmental Science and Toxicology

The global population growth and rapid industrial development have led to the recognition and increasing understanding of the interrelationship between pollution, public health and environment. Organic pollution indicators and anions concentration of surface water from River Galma around Dakace industrial Layout, Zaria were monitored between May 2011 and May 2012 using standard analytical methods. The levels of Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) ranged from 4.16 to 6.82 mg/l, 2.66 to 4.28 mg/l and 7.08 to 12.76 mg/l respectively. Anions concentrations which include phosphate (PO43-), nitate (NO42-) and sulphates (SO42-) were of the ranges 31.6-49.23 mg/l, 0.32-4.31 mg/l and 2.32-10.78 mg/l respectively. It was established from the results of this study that industrial discharges from Dakace industrial layout had significant negative impact on the surface water quality of the river. Hence, extraction of water from the river for domestic and agricultural purposes requires some forms of physical and chemical treatment.
