Abstract. Muscle portion of 72 fish samples of eight selected species, four from marine (Pampus Chinensis, Otolithes ruber, Trachipteridae and Oncorhynchus tshawytscha) and four from fresh water (Labeo rohita, Catla catla, Rita rita and Walago atu) fishes were collected from three superstores in Lahore, Pakistan. The prepared fish samples were analyzed for determination of Chromium (Cr), Lead (Pb) and Cadmium (Cd) concentrations by using the inductively coupled plasma (PerkinElmer, Model: Optima 7000DV ICP-OES). It was found that Cd (0.294±0.001 mg/kg) concentration was the highest in Labeo rohita collected from Metro Superstore while the lowest level (0.023±0.000 mg/kg) was in the Oncorhynchus tshawytscha of the same superstore. Species wise concentration of Cd varies significantly. Concentration of Cr (0.172±0.001mg/kg) was the highest in Oncorhynchus tshawytscha collected from Main Fish Market of Lahore while the lowest level (0.002±0.001mg/kg) was in Labeo rohita collected from Hyperstar superstore. Concentration of Pb (0.057±0.000mg/kg) was the highest in Oncorhynchus tshawytscha collected from Metro Superstore while the lowest (0.012±0.001mg/kg) in Otolithes ruber of the same superstore. Species wise concentration of Pb varies non-significantly. Origin wise t-test shows that: a) Cd concentrations vary significantly, while Cr and Pb concentrations vary non-significantly when marine and fresh water species were compared. b) The range of Pb (0.011-0.057 mg/kg) and Cr (0.002-0.172 mg/kg) was within limits and of Cd (0.023-0.297 mg/kg) was higher than the WHO international standards (0.123 mg/kg for Pb, 0.050 mg/kg for Cd and 0.1 mg/kg for Cr) in most of the fish species of main Fish Market Lahore, Hyperstar and Metro store.

Background. Pollution of the aquatic ecosystem by heavy metals is increasing due to anthropogenic activities. Cadmium (Cd) can accumulate in soil, be taken up by plants, and passed on in the food chain to animals and humans. Objectives. The present study was conducted to analyze the uptake of Cd in muscles of sampled fish with different feeding habits and to compare levels of Cd in fish from the Ayeyarwady River, Myanmar with international standards. Methods. The acid digestion procedure was used for sample preparation. Cadmium concentrations in fish samples were determined by flame atomic absorption spectrophotometry (Perkin Elmer AAanalyst 800 and Winlab-32 software). Results. In herbivorous fish species, Cd content ranged from 0.07 ( Catla catla ) to 0.086 mg/kg ( Osteobrama belangeri ). In carnivorous fish species, Cd ranged from 0.060 ( Mystus leucophasis ) to 0.083 mg/kg ( Wallago attu ). In omnivorous fish species, Cd ranged from 0.07 ( Botia histrionica ) to 0.084 mg/kg ( Gudusia variegata ). Cadmium content did not differ significantly across the three types of feeding habits (p>0.05). Discussion. The accumulation of Cd in the muscle of studied fish was lower than the permissible limit set down by the European Union in 2001 (0.1 ppm), but above the limits set down by the Food and Agriculture Organization/World Health Organization, European Commission (0.05 ppm) and within the limit of United States Food and Drug Administration (0.01–0.21 ppm). The data obtained in the present study indicate that levels of Cd were not significantly different across fish species with different feeding habits. Conclusions. The examined fish samples were not fully safe for human consumption due to high levels of Cd. Competing Interests. The authors declare no competing financial interests.

The study revealed the status of formalin used in four commercially important fishes namely Rohu (Labeo rohita), Catla (Catla catla), Mrigal (Cirrhinus cirrhosus) and Hilsa (Tenualosa ilisha) from Sylhet and Moulvibazar district for a period of four months from April to July 2016. A total of 100 fish samples from different town and village markets were collected and analyzed instantly on the market to detect the presence of formalin by using a kit developed by Bangladesh Council of Scientific and Industrial Research (BCSIR). Among the analyzed fishes 46.7, 26.7, 20.0 and 13.3% of Rohu, Catla, Mrigal and Hilsa, respectively were found treated with formalin from Sylhet district. Similarly, formalin was also detected in 40, 20, 20 and 20% of investigated Rohu, Catla, Mrigal and Hilsa from Moulvibazar district, individually. There was no significant difference in formalin used between town and village market, whereas a significant difference in application of formalin in domestic and imported fishes except Catla has been identified. Two-third of imported Rohu (66.7%) was found formalin positive followed by Hilsa (44.4%), Mrigal (40%) and Catla (35.7%). Amongst the domestic fishes, presence of formalin was detected in 27.8, 18.8, 10.0 and 4.8% in Rohu, Catla, Mrigal and Hilsa, separately. This devastating use of formalin in food fishes should be banned through proper enactment of the existing laws of the country, as well as timely and appropriate implementation of government monitoring is mandatory to combat the unethical formalin use.

In this study, the concentrations of some heavy metals including Al, Cu, Fe, Mn, Zn, Cd, Co, Cr, Ni and Pb were determined in the muscles of three commercial fish species available in Duhok city markets in two seasons, using inductively coupled plasma-optical emission spectrometry (ICP-OES), after the wet digestion process. Lowest and highest mean values of metals in µg/g (dry weight) were as follows: Al: Under Detection Limit (UDL)-3.71, Cu: UDL-4.00, Fe: 5.40-21.44, Mn: UDL-3.45, Zn: 13.38-140.11, while Cd, Co, Cr, Ni, and Pb were not detected. The highest levels of Al, Fe and Zn were recorded in Shukhat fish species, and the highest levels of Cu and Mn were recorded in Shabout in the winter season. The highest level of all metals was recorded for Zn (172.8 µg/g) with the highest mean value of (140.11 µg/g) in Shukhat species during winter.  Most heavy metal concentrations were below the international permissible limits for fish, however, some of the maximum and mean values of metals were above the international standards. Fe concentrations were above the maximum allowable limits set by WHO (1999). Zn concentrations were above the maximum permissible limits set by joint FAO/WHO (1989) and FAO (2012).

Abstract River ecosystems are vulnerable to heavy metal pollution. Fish samples are considered as one of the most indicative factors, in fresh water systems, for the estimation of trace metals pollution potential since they are the final chain of aquatic web. The objective of the present study is to evaluate the concentration of some toxic elements (As, Hg, Pb, Cd and Ni) in edible part of three wild fresh water fish species (zander (Sander lucioperca), wels catfish (Silurus glanis) and European carp (Cyprinus Carpio)) caught from Bulgarian part of Danube river collected during 2010. The Danube River is the European Union's longest and the continent's second longest river that passes through or touches the borders of ten countries. It has a great importance in regard to biodiversity, economics and transportation. The elements (As, Pb, Cd and Ni) were assayed using Perkin Elmer Zeeman 3030 electrothermal atomic absorption spectrometer with an HGA-600 atomizer. Determination of Hg was performed using Milestone Direct Mercury Analyzer DMA-80. The results were expressed as μg/g dry weight. The order of heavy metal accumulation in the edible part of zander is As>Hg>Pb> Ni> Cd while the other two fish species show a different metal accumulation Hg > As >Pb> Ni > Cd. In all heavy metals, the accumulation of mercuric and arsenic proportion was significantly high in all three fish types.

Background: Among the local fish species in Bangladesh, Labeo rohita and Barbonymus gonionotus are two popular fish species. The present work focused on proximate compositions (moisture, protein, fat, and ash) and risk assessment of lead in two common fishes (L. rohita and B. gonionotus) collected from river and farms of Bagerhat, Bangladesh. Furthermore, effect of freezing condition on fish lipid was studied.  Methods: Proximate compositions of the fish samples were determined according to conventional methods. The lead contents were analyzed by wet digestion method using an atomic absorption spectrophotometer. The health risks models such as Estimated Daily Intake (EDI), Target Hazard Quotient (THQ), Hazard Index (HI), and Target Cancer Risk (TCR) were conducted for health risk assessment of the local people. Data were analyzed using SPSS software (version 16.0).   Results: A positive correlation was found between moisture-protein and lipid-ash of the L. rohita fish. Besides, a positive relation was observed in ash-moisture, and lipid-protein for B. gonionotus. The lead content in river L. rohita, farm L. rohita, river B. gonionotus, and farm B. gonionotus was observed as 9.00, 9.20, 8.29, and 6.39 mg/kg, respectively. The lead content found in the fish species were above the permissible limit. The TCR revealed the carcinogenic effects to the local people due to exposure of lead. Conclusion: This study reflects some data about proximate values of L. rohita and B. gonionotus fishes. The concentrations of lead in the fish samples were above the safe limits, and may have carcinogenic effects of the local consumers in Bagerhat, Bangladesh.
