Lead accumulation in and its haematological effects on African catfishClarias gariepinus

Calcium Carbide-Induced Haematological Alterations In The Albino Mice- Mus musculus

“…Adhikari et al [12] and Ogbuagu et al [13] had observed that haematological parameters are pathophysiological reflectors of the whole body of an organism (fish), even as Alimba et al [14] stated that one among the validated methods for investigating the immune-toxic potentials of toxicants, primarily in rodents is change in cellular components of blood. Comparatively lower white blood cell counts were recorded in mice exposed to toxicant concentrations than the unexposed group.…”

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.…”

“…Whilst some of these metals are essential in trace amounts to living organisms, they may become highly toxic when present in high concentrations. 2,3 Bioaccumulation in the tissues of organisms has been identified as an indirect measure of the abundance and availability of these metals in aquatic environments, 4 and the rate of accumulation depends on the ability of the organism to digest the metals, plus the concentration of such metals in the water body. The rate of bioaccumulation also depends on the concentration of the metals in the surrounding sediments, as well as on the feeding habits of the organism.…”

The Effects of EDTA on Lead Accumulation in Tissues of Clarias gariepinus

“…In studies conducted with various fish species under both natural and laboratory conditions, it has been found that metal accumulation varied with the tissue and organ (Alves and Wood, 2006;Shukla et al, 2007;Banaee et al, 2013;Ogbuagu et al, 2015). The liver is an important organ that functions in detoxification and biotransformation of xenobiotics, as well as in metabolic events (Van Dyk et al, 2007).…”
