Abstract

Microbiological and physicochemical quality of Imo River was investigated to determine the effects of paper recycling mill effluent.  Samples were collected at five different points for six consecutive months (March to August). Generally the month of July recorded the highest microbial counts for both bacteria and fungi at the different points. The Downstream I and Downstream II sampling points recorded lower microbial counts, followed by upstream sampling point when compared to effluent discharge sampling point. The physicochemical assessment revealed remarkable changes between the upstream (3.89mg/l), discharge point (16.71mg/l) and downstream stations (12.22mg/l) for biochemical oxygen demand. Total dissolved solid values were for the upstream (182.33mg/l), discharge point (365.67mg/l) and downstream stations (215.55mg/l). Dissolved oxygen at the upstream station was 6.59 mg/l and discharge point was 3.95 mg/l). Variations in pH, temperature, turbidity, phosphate, nitrates, iron, copper between the upstream, discharge point and the downstream stations were noticeable. There is a significant difference (P <0.05) between months of sampling as well as sampling points. The study revealed that the river was affected by paper recycling mill effluents discharged into it to various degrees at different sampling points on different months.
