Assessment of heavy metals in fish species and some physico-chemical parameters of Oguta lake, Oguta, Imo state, Nigeria

“…The results of the Physico-chemical parameters of Oguta Lake, are shown in Table 1 The observed significant variation in surface water temperature, free carbon (iv) oxide, dissolved oxygen, total hardness, and ammonium-nitrate of the current work may have affected the speed of one or more of the biochemical reactions, the metabolic rates of the organism, how pollutants interacted with the organism, and other materials in water, as also observed by Ogbuagu et al 3 UNEP GEMS 12 and Akinrotimi et al 13 These variations may be related to patterns of water use, weather conditions, water depth, and run-off that brought in different allochthonous materials during the rainfall. Similar observation have been previously reported by Atobatele and Ugwumba 14 Mustapha 15 Edward and Ugwumba, 16 Spaak and Bauchrowitz 17 and Usman 18 where it was stated that water quality largely regulates the distribution and productivity levels of resident organisms, and that changes in it can alter natural biodiversity. On the other hand, the observed direct correlation between surface water temperature and ammonium-nitrate at p<0.01, and hardness and free carbon (iv) oxide at p<0.05 reflects the significantly contributions of these parameters to the recorded variation in the physico-chemical parameters of the lake, and their subsequent enhancement in the solubility of the introduced contaminants.…”

Flora composition of phytoplankton as bioindicators of water quality in Jakara dam, Kano state, Nigeria

“…Counting The species were directly counted under microscope. The phytoplankton were identified based on taxonomical classification to species level using the identification keys by Botes (2001), Dietrich (1979), Durand and Lévéque (1980), and Edward and Ugwumba (2010).…”

Effects of physico-chemical parameters on the composition and abundance of phytoplankton in Ajiwa Reservoir Katsina State, north western Nigeria

“…Maintenance of healthy aquatic environment and production of sufficient foods in reservoir are primarily linked with successful reservoir culture operations. To keep the aquatic habitat favourable for existence of living organisms, physical and chemical factors like temperature, turbidity, pH, odour, dissolved gases, salts nutrients must be monitored regularly, individually or synergistically, activity of living organisms is influenced by the seasonal and diurnal changes of these parameters (Akinyeye Changes in the physico-chemical parameters may positively or negatively affect the biota of water bodies in a number of ways such as their survival and growth rates and these may eventually result in disappearance of some species of organisms or its reproduction (Edward and Ugwumba, 2010). Life in aquatic environment is largely governed by physico-chemical characteristics and their stability.…”
