“…Studies carried out with different fish species have revealed that non-essential metals can produce toxic effects in fish by disturbing physiological activities [4], biochemical processes [5], reproduction and growth [6]. Among the heavy metals, Cd is one of the most toxic, nonessential heavy metal and accumulates in tissues of aquatic organisms like fish [7,8]. Problems with Cd bioaccumulation were studied by many authors in aquatic animals [9][10][11][12][13][14].…”

Objective: The present work was carried out to know the therapeutic role of zinc (Zn) and calcium (Ca) supplementation to combat cadmium (Cd) induced toxicity in selected tissues of freshwater teleost, Oreochromis mossambicus (Tilapia) exposed to Cd. Methods:The freshwater fish, Oreochromis mossambicus (Tilapia) was brought from the local ponds and were allowed for acclimatization to the laboratory conditions. After acclimatization, fishes were exposed to 1/10 th of LC50/48 hr of Cd i.e.5 ppm for 7, 15 and 30days (d) long sojourn. After 15d Cd exposure, fish were divided into three groups. The 1 st Results: A significant (P<0.05) elevation was observed in bioaccumulation levels during Cd exposure. The high amount of Cd accumulation was found in 30d Cd-exposed kidney (22.353±0.410 µg/g) followed by other tissues. After supplementation with Zn and Ca, Cd accumulation was progressively decreased in all the test tissues. The maximum percentage of Cd depletion was found in 30d Ca-supplemented muscle tissue. group was supplemented with Zn at a dose of 1 ppm; Group-II was supplemented with Ca at the dose of 1 ppm and Group-III received a combination of both Zn and Ca at the above said doses for 7, 15 and 30d. After specific time intervals, fish were sacrificed and liver, kidney, brain, gill and muscle tissues were isolated in ice cold conditions. Then the tissues were used for bioaccumulation studies. Conclusion:Our findings clearly envisage that the Zn and/or Ca supplementation is very effective in reducing the Cd toxicity in the teleostean fish, Oreochromis mossambicus.

“…Then, they were cooled, filtered, and placed in plastic bottles. Acidic digestion of the sample was done according to the procedures mentioned in [32], but the mineralization procedures were modified for the current study. The determination of heavy metals in the fish tissues was carried out using an atomic absorption spectrophotometer (Perkin-Elmer model 5000, Perkin-Elmer Corp, Waltham, MA, USA).…”

Abstract:The presence of heavy metals in freshwater fish represents a global public health issue. The current study aimed to determine the heavy metal concentration and toxicity in some freshwater fish species collected from the Tigris River in Baghdad. Out of the many fish species in Iraq, the current study selected the Genus Barbus as it represents the most popular fish food in Iraq. The sample included twenty fishes and the selected sample locations covered two industrial areas in Baghdad (one north of Baghdad and one south of Baghdad). The levels of heavy metals were determined by using an atomic absorption spectrophotometer (AAS). The results showed that concentrations of heavy metals in the sampled fishes exceeded the acceptable levels for food sources for human consumption. The results of this study showed high levels of cadmium and chromium levels in the tissues of the selected fish sample. Cd and Cr were among the highest concentrations and both exceeded the World Health Organization and Food and Agriculture Organization of the United Nations acceptable levels for heavy metals in fishes.

“…Bioaccumulation of Iron (Fe) was above FEPA and WHO limits. Murtala et al [6] detected high value at downstream Ogun coastal water and were also above the recommended limit but not as high as those recorded in the study area. Ayoola and Dansu [26] reported lower concentrations of Cadmium (Cd), Chromium (Cr), Lead (Pb) and Zinc (Zn) in Chrysichthys nigrodigitatus and Pythonichthys macrurus collected at Makoko fishing site compared to the current study; the concentrations of heavy metals in the fish samples were above WHO permissible limit.…”

“…Heavy metals are found in marine environment that occur because of pollution which is due to the discharge of untreated wastes into water bodies by industries and runoffs. [6]. Many pollutant are found in crude oil due to its geological proximity most especially heavy metals, since they play important role in biological systems, whereas mercury, lead and cadmium are toxic, even in trace amounts.…”

A B S T R A C TIndustrial waste discharge has increased the hazard of water pollution. The total hydrocarbon content and bioaccumulation of heavy metals in Sarotherodon melanotheron at Atlas cove area and at Okobaba end of Lagoon Lagos were assessed between November, 2014 and January, 2015. The physicochemical parameters were determined according to APHA-AWWA-WEF and heavy metals in the fish species were determined using Atomic Absorption Spectrometer. The total hydrocarbon content (THC) in the fish samples were analysed by using Soxhlet extraction gravimetric methods. The heavy metal values evaluated are Fe, Cr, Pb, Ni and Cu. The concentration of Iron (Fe) in Sarotherodon melanotheron was 72.72 ± 125.95mg/kg, Chromium (Cr)-10.29 ± 4.61mg/kg; Lead (Pb)-1.08 ± 0.23mg/kg; Nickel (Ni)-0.39 ± 0.26mg/kg; and Copper (Cu)-0.20 ± 0.26mg/kg at Atlas cove area while at Okobaba the concentration were;Fe-115.98±87,Cr-5.25±1.02,Pb-2.04±1.50,Ni-0.78±0.08,and Cu is 0.36±0.15mg/kg. The levels of accumulation of all the heavy metals in Sarotherodon melanotheron were above the WHO permissible limits. The concentration of n-alkanes in Sarotherodon melanotheron at Atlas cove was 164.69 ± 97.04µg/g, polycyclic aromatic hydrocarbon (PAH) was 73.58 ± 72.48µg/g, and total petroleum hydrocarbon was 526.67 ± 214.34µg/g. The average intake of polycyclic aromatic hydrocarbon through fish consumption at Atlas cove area was estimated to be 5039.94 ± 49.2mg/kg; body weight/day. The mean concentration of nalkanes hydrocarbon in Sarotherodon melanotheron at Okobaba was 152.62±54.11µg/g, the Polycyclic Aromatic Hydrocarbon (PAH) was 74.4±50.30 µg/g.The carcinogenic high molecular weight polycyclic aromatic hydrocarbons (HMW-PAH) were of higher concentrations than the lower molecular weight polycyclic aromatic hydrocarbon (LMW-PAH). Therefore, Atlas cove area is more exposed to carcinogenic health risks associated with the consumption of the studied fish than Okobaba end of Lagos Lagoon. This indicates significant carcinogenic health risks associated with the consumption of black jaw Tilapia fish caught from the study areas.
