Seasonal Variation in Interstitial Fluid Quality of the Andoni Flats, Niger Delta, Nigeria

EJ Ansa, FD Sikoki, A Francis, ME Allison


Physicochemical characteristics of the interstitial fluid of the sediment of the intertidal and subtidal zones of the Andoni flats were studied. The results for the interstitial fluid showed low dissolved oxygen levels (0.1 –
1.3mg/l), high temperature values (26.2 -32.4°C), wide salinity range (8 – 21ppt) and near neutral pH (6.26 – 7.76) across stations. Sampling duration was from January 1999 to December 2000 covering both wet season (April –October) and dry season (November – March). The implications of the effects of fluctuating environmental variables on in-fauna inhabiting sediment are discussed
