Topic: Toxicological Impacts, Physicochemical Parameters And Heavy-metal Bio-accumulation In Fish From Industrially Polluted Areas Of Lagos State

Description: The industrially polluted areas hot-spots of Lagos lagoon are Ologe lagoon, Badagry creek and Lagos lagoon; which play host to several industries from where various pollutants effluents find their way in to the aquatic environment all year round and having great impacts on the ecology of the lagoon system. the scenario described above give rise to water pollution, massive fish kill, and general degradation and possible human health implications. the research aim at cataloging these impacts and using scientific approach to find ways of giving appropriate advice to policy makers on reduction of devastating consequences possible in the near future.Fish are relatively sensitive to changes in their environment as a result of pollution. fish health may thus reflect and give indication of the health status of a specific ecosystem. in this proposed study, emphasis is on the toxicity of effluents on survival, physiological, morphological and haematological changes in fishes.

VARIATIONS IN PLASMA BIOCHEMICAL INDICES OF BLOOD AND ORGANS AS BIO-MARKERS IN THE AFRICAN CATFISH, Clarias gariepinus and SILVER CATFISH, Chrysichthys nigrodigitatus FROM OLOGE LAGOON, LAGOS, NIGERIA

The preliminary aspect of this study elucidated the ecology of Ologe lagoon by assessing the physicochemical parameters and heavy metals in water, fish and sediment. The focal area of the research was to determine the biochemical alterations in the gills, liver, heart and blood biomarkers ALT, AST, ALP, GST, CAT, GSH, SOD, GPx and Protein conc. of C. gariepinus and C. nigrodigitatus. Physicochemical parameters were determined using standard methods, while the heavy metals concentration were assessed using the atomic absorption spectrophotometer AAS and the biochemical indices were determined using standard methods as prescribed. The results revealed mean Temp. 24.360C ; pH 7.23 ; turbidity 4.03FTU ; TSS 8.0mg/l ; TDS 1038.6mg/l ; TS 1045.6mg/l ; alkalinity 50.0mg/l and Dissolved oxygen 6.9mg/l . Heavy metals were low in the water phase, but slightly higher in the fish tissues and highest in the sediment with zinc 21.95mg/kg ; Fe 24.27mg/kg ; Pb 2.73mg/kg ; Mn 2.57mg/kg ; Cd 0.61mg/kg and Ni 1.84 mg/kg . The results of biochemical indices showed highest ALT and ALP in the gill 7.35mg/protein, and 1.66 /ml in C. gariepinus; highest GST and SOD values 0.007 /ml, 0.81 mg/protein were also observed in liver of C. gariepinus; GSH was highest in the heart of C. gariepinus with 0.08 mol/mg. The results generally showed that C. gariepinus is more adaptive to the polluted environment than C. nigrodigitatus. Government and non-governmental organizations should intensify effort to reduce the amount of industrial effluent spillage of oil, petro-chemicals and other xenobiotics to manage their impacts on biochemical indices.
