Impacts Assessment of Coastal Activities on Water Quality of Upper Segment of Qua Iboe River, Akwa Ibom State, South-South, Nigeria
A study was carried out at the supper segment of Qua Iboe River from
November, 2018 to August, 2019 in four sampling stations to assess the
impacts of coastal activities on water quality. Water samples were
collected monthly and analyzed using standard procedures of
Associations of Official Analytical Chemist and American Public Health
Association. The stations comparisons and location of significant
differences were carried out using ANOVA and Least Significant
Difference (LSD) test, while paired sample t-test were employed to
compare the seasonal difference. The mean ranged values of water
temperature were (25.03 \u2013 25.330C), pH (5.8 \u2013 6.6 mg/l),
DO(3.11 - 5.45 mg/l), TDS (18.63 \u2013 32.53mg/l), EC
(8.33-13.16\u3bcs/cm), Turbidity (7.61 \u2013 18.32 NTU), TSS (90.80
- 165.63 mg/L), NO3-1 (33.02 \u2013 78.33mg/l), P043-(4.44 \u2013
7.39mg/l), Cl-(43.60 \u2013 63.21mg/l), COD(35.96 \u2013 113.05mg/l),
NH3(0.33 \u2013 0.62 mg/l). Mean values of TSS, EC, TSS, NO3, PO43-,
NH3 and turbidity were higher in wet season, while water temperature,
pH, DO, Cl- and COD values obtained were higher in dry season. Spatial
variations in parameters were ascribed to levels of anthropogenic
activities and wastes discharged within the stations; the seasonal
variations were emanated from influx of wastes, and dilution as result
of surface run-offs during wet season. Based on the findings, the WQI
values were poor for human consumption; especially from station 2 to
4.These calls for urgent attention by Federal / State Ministry Health
and Environment regards to its effects on human health and consistent
water quality monitoring should be put into consideration
