Bioaccumulation of Heavy Metals in Common Carp: Implications for Human Health

Authors:

Abstract and Figures

Zn, Ni, Cr, Cu, Cd and Pb were examined in the muscle, intestine, liver, skin and gills of common carp, Cyprinus carpio. Aim of the study was to quantify the accumulation of these metals in various organs and to determine whether these levels pose a human health concern. Our finding fix the metal bioaccumulation order in the muscle of Cyprinus carpio was Zn>Cr>Cu>Pb>Ni>Cd, in the intestine was Zn>Pb>Cr>Cu>Ni>Cd, in the liver was Zn>Cr>Cr>Pb>Ni>Cd, in the skin was Zn>Cr>Pb>Cu>Ni>Cd and in the gills was Zn>Cr>Cu>Pb>Ni>Cd. Overall heavy metals burden was in the order of Zn>Cr>Pb>Cu>Ni>Cd. Different tissues of the fish accumulated heavy metals in the order of intestine>skin>liver>gills>muscle. Intestine being the prime target organ indicates the route of the metal uptake was the direct result of dietary exposure. Although muscle accumulated the least level of metals but even then Pb, Ni and Cd in muscle exceed the US, RDA limits and pose a health concern for fish consumers.

Abstract
During the exploration of basidiomycetes of Pakistan, twenty gasteroid fungi were collected and identified from district
Mansehra, Pakistan. Out of these, nine specimens represented different taxa; two belong to genera Geastrum and Lycoperdon,
one each species belonged to genera Astraeus, Bovista, Phallus, Pisolithus, and Scleroderma. These gasteroid taxa have been
identified, described and discussed. Among these, Phallus hadriani is a second report for Pakistan, and four gasteroid taxa are
new records for District Mansehra. © 2014 Friends Science Publishers

Introduction
District Mansehra is located in Hazara civil division of the
Khyber Pakhtunkhwa Province, Pakistan. It is situated
between 34
o
–14 and 35
o
–11’ north latitudes and 72
o
–49
and 74
o
–08’ east longitude. It consists of Mansehra, Balakot
and Oghi tehsils. The district spread over an area of 5959
km
2
(Shah and Khan, 2006) and has been blessed with high
mountains, lakes, beautiful valleys, plains and more
especially the rich and harmonious combination of tall and
stately fine trees. The mountains of the northern side are
also the extension of the same mountain system. From the
north east, Musa-ka-Musala a peak (4080 meters), which
lies along the north eastern side of Konsh and Bhogarmang
valleys (Mustafa, 2003). On the western side of Agror
valley (Oghi) there is a famous black mountain range which
runs northwards (Mustafa, 2003). The climate of the district
is moist temperate with seasonal periods of rainfall, snow,
and drought (Mustafa, 2003). Forests of the district are rich
in trees as Deodar, Blue pine, Chirr, Walnut, Cherry, Poplar
and Kao (SMEDA, 2009) and supports a rich diversity of
macro fungi during monsoon. Gasteroid fungi represent a
major group belonging to macro fungi. Most of the
members of this group viz., Astraeus, Pisolithus,
Scleroderma are involved in ectomycorrhizal associations
with some coniferous trees (Martin, 2001; Turjaman et al.,
2005; Pyasi et al., 2011; Kaewgrajang et al., 2013). Some
members belonging to genus Bovista, Lycoperdon are edible
and have medicinal value (Lans et al., 2007, Ramesh and
Pattar, 2010).
So far only 17 gasteroid fungi have been reported from
different areas of district Mansehra (Ahmad, 1939, 1952a, b,
1956, 1969, Khan 1968, Ahmad et al., 1997). In present
investigation, nine gasteroid taxa have been reported, out of
which one is new record for the country, four are new
record for district Mansehra and 5 taxa are being described
from different localities of district Mansehra for the first
time.
Materials and Methods
Basidiomata were collected with the help of a sharp digger
avoiding the loss of rhizomorphs. Specimens were dried
manually and brought to laboratory for further investigation.
Morphological characters (e.g., basidiospores, capillitium,
endoperidium, and exoperidium) were observed
macroscopically using a stereomicroscope (Meiji Techno
EMZ-5TR) and studied under light microscope (Nikon YS
100) at high magnification (1600x). Glebal material was
examined when mounted in lacto-phenol and 5% KOH
medium. Illustrations of microscopic features were prepared
with the help of a camera Lucida (Ernst Leitz Wetzlar
Germany) fitted to a light microscope.
Specimens were identified with the help of literature
(Coker and Couch 1928; Bottomly, 1948; Miller and Miller,
1988; Ellis and Ellis, 1990; Pegler and Spooner 1995). All
of the specimens have been deposited in the collection of
gasteroid fungi at the LAH Herbarium, Department of
Botany, University of the Punjab, Lahore, Pakistan.

The current work was done to assess the levels of heavy metals by using an Atomic Absorption Spectrophotometer in three commercially important fish species comprising, Cirrhinus mrigala, Glyptothorax punjabensis, and Mastacembelues armatus of the Swat River at Charsadda, Khyber-Pakhtunkhwa Pakistan. The different parts of fish i.e., gill, muscles, livers, and kidneys were examined. The results obtained revealed that the liver had the greatest level of heavy metal buildup, whereas the lowest was recorded in the edible part of fish (muscles) which is within a safe limit. Overall, concentration was found to exceed the international standards permissible limits. Pb was characterized to be the most frequent heavy metal found in all parts of the selected fish species, also to figure out whether there are statistically significant variations between the mean heavy metal content of each fish species and organ, one-way analysis of variance (ANOVA) was used. In brief, ANOVA and Tukey's HSD tests reveal significant differences in the heavy metal content among the fish species and organs for all metals except for Cu. The results suggest that the heavy metal content of fish can vary significantly depending on the species and the organ being analyzed, which highlights the importance of monitoring heavy metal levels in fish intended for human consumption.
... Karadede et al. (21) were referred to that the heavy metals that can combine with mucous materials in gills forming hardly removable complexes. Yousafzai et al. (22) combined the attraction between the positively charged heavy metals and the negatively charged phospholipids found in the mucous lining epithelium of fish gills. ...
... Yousafzai et al. (22), which concluded that the concentrations of heavy metals were higher in the intestine of C. carpio fish than in other body organs. They excluded that Co metal inter fish body during nutrition rather than respiration (through gills). ...
... This status result is fortunate since the skeletal muscles of fish are put on the main food lists for humans and the mean concentrations of the studied metals, Mn, Ni, and Co, did not reach the lower permitted levels of such metals in fish tissues by FAO and FDA 4.4-7.9µg/gm of fish muscles for Mn, 17.8-20 µg/gm for Ni and 2.6-5.39µg/gm for Co (33). Besides, we must consider that the over threshold accumulation of heavy metals in fish muscles may hazard human health (22,34). The relatively low concentration of heavy metals in fish muscles may indicate the weak or disability of muscle proteins to combine with these heavy metals (35). ...

Concentrations of three heavy metals as Manganese, Nickel, and Cobalt were estimated in two levels in the food chain; the omnivorous Cyprinus carpio fish and its intestinal cestode Bothriocephalus acheilognathi as end consumer (endoparasite) using atomic absorption technique. The study was performed in two locations in Tigris River, Al Rashedia and Sherikhan villages/Mosel City/ Nineveh Province between June 2022 to October 2022. The concentration of the three chosen metals: Mn, Ni, and Co, was estimated in the liver, gills, intestine, and skeletal muscles in both infected and uninfected fish and added to tissues of the cached Cestoda. Manganese concentration was the highest in the gills of both infected and uninfected fish 14.597, 21.773 µg/gm fresh weight, nickel concentration was the highest in the liver 4.44 and 8.10µg/gm fresh weight, and cobalt concentration was the highest in the intestine 2.467 and 7.79 µg/gm fresh weight. The difference in values was significant at P≤0.05 in the infected and uninfected fish, respectively. Accumulation of the three metals Mn, Ni, and Co was the lowest in fish skeletal muscles. Mn had the highest accumulation mean in fish organs 11.846 µg/gm fresh weight, Ni was the next 4.094 µg/gm, and Co was the lowest 2.616 µg/gm. The concentration of Mn and Ni in the cestode B. acheilognathi tissues 22.53 and 10.45 µg/gm was about two folds of that found in its host fish C. carpio. The concentration of Co was approximate in the worm tissues and its host fish. In conclusion heavy metals in C. carpio didn't exceed the WHO and the FAO set permissible levels. B. acheilognathi cestoda could be a useful bioindicator for heavy metal contamination in aquatic ecosystems.
... Fish that accumulate heavy metals from food, exhibit high level of metals in the digestive tract in contrast to gills. Our findings are in accordance with Yousafzai et al. (2012) who also accounted highest possible accumulation of heavy metals in intestine of Cyprinus carpio followed by skin, liver, gills and least in muscles indicating that the foremost target body organ of heavy metals here is the intestine. Similarly Bury et al. (2003) also reported in gold fish that the intestine worked as the bulk pathway for the uptake of heavy metals like zinc. ...
... This may be due to the growth factor since growth can dilute the concentration of toxic substances, if growth is more rapid than accumulation. Yousafzai et al. (2012) reported considerably less amount of metals in the muscle tissues of Cyprinus carpio. Similar investigations were also reported by Shukla et al. (2007) that concentration of zinc, cadmium, and copper was optimal in liver and minimal in muscle tissues of Channa punctatus. ...

The current research was conducted with the aim to investigate the rate of chromium accumulation in various tissues of commercially valuable freshwater fish, Grass Carp, Ctenopharyngodon idella. Investigation included various tissues of skin, muscles, liver, swim bladder, intestine, and gills in fish. For this purpose, the fish were exposed to sub lethal concentration of hexavalent chromium in the form of potassium dichromate with a dose of 120 mg/L for 40, 20 days and 10 mg/L for 7, 25, 40 and 60 days. Forty fish of the same weight and length (70.45±2.91 g and 7.32±0.16 inches) were used in the present research. Chromium was estimated after acid digestion of the sample tissues and further analyzed through atomic absorption spectrophotometer (Spectra AA6300 China). The results showed that in all the experiments intestine remained the highly accumulative tissue and the accumulation of chromium in the intestine increased with the increase in exposure time i.e., 0.63±0.21 after 7 days, 0.83±0.35 after 25 and 1.63±0.44 after 60 days. Finding of this research work supports that the route of metal uptake was mainly oral instead of absorption by gills or skin.
... Because of the accumulation of pollutants in the aquatic ecosystem in fish tissues, fish are widely used to assess the health of the aquatic ecosystem. For this reason, many metal toxicity studies on fish have been carried out by many scientists in recent years [13][14][15][16][17][18][19][20]. In order to understand the effects of different doses of metals on enzymes in fish tissues, detailed studies are required both in vivo and in vitro. ...
... In general, the log BCFs of the heavy metals in the fish in previous studies were in the range of reported values (Pandey et al. 2017;Vu et al. 2017). For example, the log BCFs of Zn and Pb in this study were higher than those reported in central and eastern North China (Zhong et al. 2018), the freshwater fish in northern méxico (Luna-Porres et al. 2014) and lower than those in Cyprinus carpio in Pakistan river (Iqbal and Shah 2014;Yousafzai et al. 2012). ...

y This cross-sectional study was conducted to determine and compare the concentrations of heavy metals (Zn, Pb, Cd, and Hg) in carp-farming water and muscle of various carp species including common carp (Cyprinus carpio), bighead carp (Hypophthalmichthys nobilis), silver carp (Hypophthalmichthys molitrix), and grass carp (Ctenopharyngodon idella) collected from three major warm-water fish farms in Mazandaran Province (Iran) during March 2018 to March 2019. In addition, bioaccumulation of heavy metals (BCFs) and carcinogenic and non-carcinogenic risk assessments of consumers exposed to heavy metals through fish consumption were estimated. The water concentration of all metals in this study was lower than permissible limits. The concentration of Zn in the water (10.21–17.11 μg L⁻¹) was higher than that of other metals in all sites, followed by Pb > Cd > Hg. In fish muscle, Zn concentration in silver carp was the highest, and the lowest concentrations were related to Hg and Cd in common carp and grass carp, respectively. The target hazard quotients (THQ) indicated that the non-carcinogenic health risk to humans was relatively low by consuming four farmed carp species products. The carcinogenic risk of inorganic Pb was 1.24E-04 (common carp) to 2.11E-04 (grass carp) for adults, which is within the acceptable range. The values of BCFs for all metals demonstrated that farmed carp muscle could not be considered a bioaccumulative tissue for heavy metals. The results indicated that the concentrations of heavy metals in the farmed carp species in North Iran were relatively low and did not cause considerable human health risks.
... Average content of Pb in liver, kidney, muscles and skin of fish collected from Head Balloki was 83.19%, 84.40%, 38.39% and 9.47% higher respectively than that collected from Village Kala Khatai (Figure 2). Although earlier investigations (Yousafzai et al., 2012;El-Moselhy et al., 2014;Shovon et al., 2017;Bawuro et al., 2018) have reported accumulation of Pb in gills of different fish species including carps, this metal was not detected in gills of any fish species in present study. Gills are directly involved in exchange of metals from surrounding water and accumulation of a metal in fish gills is an indicator of its concentration in surrounding water (Shovon et al., 2017). ...

Present study was conducted to investigate the content of toxic heavy metals; lead, cadmium, manganese, nickel and zinc in organs of edible fish of River Ravi. Samples of Labeo rohita, Cyprinus carpio, Gibelion catla and Cirrhinus mrigala were captured from two sites at River Ravi i.e. Kala Khatai and Head Balloki. Zinc and lead content was higher in organs of fish specimens collected from Head Balloki than those collected from Village Kala Khatai. Higher average cadmium content was detected in most of the organs of fish collected from Head Balloki than those of Village Kala Khatai. However, higher average manganese content was found in examined organs of fish captured from Village Kala Khatai than those of Head Balloki. Lead and cadmium content in muscles of fish collected from Head Balloki was higher than acceptable level proposed by European Commission (0.2 µg/g and 0.05 µg/g, respectively). Hepatosomatic index of fish species (except L. rohita) collected from Head Balloki was lower than those of Village Kala Khatai. Study has led to the conclusion that edible fish of River Ravi is contaminated with toxic metals and contamination level is higher in fish at Head Balloki as compared to that observed at Village Kala Khatai.
... The results obtained are in full agreement with worldwide research on the zinc content in fish muscle tissue. The symmetry regarding Zn levels in carp muscle tissue from all the mentioned studies is clear evidence that muscle tissue is characterized by low levels of such metals due to their accumulation in organs such as the liver, ovaries, testicles, gills, and kidneys [115,116]. ...

The purpose of this review is to describe the contents of Pb and Zn in sediments and hydrobionts as ecological markers for the pollution assessment of freshwater objects in Bulgaria, and the data are compared with other countries and regions. Symmetry was found regarding the levels of Zn in the sediment of the Ovcharitsa and Zhrebchevo dams, which were twice the MAC for arable land (Regulation № 3 of Bulgarian legislation). Symmetry was also observed between the results for Zn and Pb in the studied sediments, and the “favorites” in terms of content were the samples from Zhrebchevo Dam and, especially, from Ovcharitsa Dam. Asymmetry was established in the accumulation of Zn in the livers of carps inhabiting Topolnitsa Dam in comparison with these in Ovcharitsa Dam. A similar asymmetry was observed for lead. The analysis of the muscles and livers of the studied fish showed an asymmetry in the accumulation of zinc, and this process was more intense in the liver. Symmetry was found in the accumulation of Pb in the liver and muscle tissues of the carp from the studied water bodies.
... Results of the current study were in acordance with the results of [43] whose founds that all study minerals in livers of C. carpio were in excess of permissible levels. Similar results have been reported that the very high fish liver concentrations of Cu, Zn, and Pb, exceeding permissible levels [44]. ...

Liver mineral concentrations of 232 samples from slaughtered animals, including lamb, yearling, sheep, and cattle, checkin, and fish were detrmined, using X-ray fluorescence spectrometer, to provide data regarding to the liver mineral concentrations (mg/kg dry weight). The mean liver Zn and Co liver conentrations of lambs (286, 1.9), yearling (233, 1.7), sheep (254, 1.8), and cattle (276, 1.8) in majority samples were adequate, while liver Pb concentrations of mentioned animals (45.3, 48.1, 46.4, 39.6) mg/kg respectively were high and exceeded toxic levels. In checkin, the mean liver Cu, Zn, and Co were also adequate, with the mean values of (26.4), (298.8), and (1.8) mg/kg respectively. Though, the mean liver Fe concentration (2257.0 mg/kg) was high, and liver Pb concentration (6.2 mg/kg) was reached toxic level. In fish, for majority liver samples, the mean concentration of Cu (191.8), Fe (6800.0), Zn (202.8), Co (3.3), Pb (8.6), and Ni (6.3) were high and toxic. In conclusion, liver Pb (and Ni only in fish) concentration in all studied animals for the majority of examined sample were higher than normal and toxic. Wherese, other studied minerals in majority of liver samples were adequate. Therefore, it can be concluded that human and animal health at a potential risk due to high

Introduction Among other aquatic animals, fish can also accumulate a large number of toxic metals in their various body organs, which may enter the human body and cause serious health issues. Therefore, the basic aim of this study was to observe the level of some heavy metals (i.e., Pb, Fe, Cu, Cd, Cr) found in the different tissues of Decapterus macarellus collected from the Karachi and Gwadar coasts of Pakistan. Methods About 200 fish samples of five different size groups of Decapterus macarellus were collected from Gwadar and Karachi fish harbors during April to September 2020. Total 10 samples of each size group i.e., S1, S2, S3, S4 & S5 were collected from each coast. Heavy metals were analyzed in fish samples by using the atomic absorption spectrophotometer (AAS). Results The overall results revealed that some metals like Cu, Pb, Cd & Cr contents were high in the stomach, while less in the muscles. Whereas, the concentration of Fe was found to be high in the liver, while low in skin of fish. The average values of bioaccumulation of these heavy metals (BAF) were found in decreasing order of Cu>Cd>Fe>Cr>Pb. In this study, except Cd and Cr, all metals were found within the permissible limits. Both sediment and water from the selected site areas were also analyzed to observe their pollution levels in the order of; sediment > water > fish tissues. Conclusion Thus, it was concluded that the Karachi environment was much more polluted than the Gwadar environment because it is in an industrial unit and a busy sea site for trade. Moreover, consuming muscles from this species is safe for human health except for iron toxicity, but the use of the liver is not beneficial for all selected metals. Thus, the present work will also be helpful to monitor these toxic metals in a food chain and maintain a healthy life, and reduce all kinds of health risks associated with them.

Fish samples (Illisha africana) were collected from six man-made fish pond in Edo and Ondo States, Nigeria. Some organs of the fish, sediment and water from the fish habitat were analysed for Cd, Pb, Hg, Ca, Fe, Zn, Cu and Cr. Physico-chemical properties of water samples from the ponds were also re-corded. The concentration of the metals varied in the sediment water as well as in different organs of the fish. However, chromium was absent in all the samples. The descending order of metal concentration in fish organs was: gills, intestine, head and muscle. To avoid harmful accumulation of these metals in the human system, the gills and the intestine should preferably be discarded while processing fish for consumption. The head with a relatively high concentration of calcium might be useful in feed formulation.
Chapter
It is well known that the progressive acidification of the lakes in Canada as well as United States and Scandinavia, has reduced drammatically the fish production in these natural areas. This phenomenon, due to acid rain, could lead to very low pH values ranging between 4.5 and 4.0. Similar decrease in pH (4.7) has been found in several rivers of Nova Scotia, once teeming with salmon, and in other remote areas of Muskoka (Ontario). Moreover, water acidification may occur even in spring, when a large amount of acid water reaches the lakes after the melting of the snow. The pH then drops to 5.5, which is particularly harmful to small fish.

Heavy metals are continuously released into the terrestrial environment by natural sources and human activities. The uptake and accumulation of heavy metals by plants promotes a mechanistic understanding of the biological significance of particular metal concentrations and distributions in biota. The toxicity of chromium, zinc, copper and cobalt ions and their binary mixtures are studied at varying test levels using duckweed as the test organism. The accumulation of metal ions are determined by atomic absorption spectroscopy. The type of toxic interactions in binary mixtures is assessed as 'synergistic', 'antagonistic' and 'additive' by a statistical approach.
