“…It has been reported that the accumulation of heavy metals in gills is because of its thinnest epithelium among all the organs of the body through which metals can easily pass [27]. Mastan [21] has also been reported the similar pattern of bioaccumulation in Labeo rohita . Experimental studies have shown that muscles of Labeo rohita accumulate least metal zinc as compared to other organs [33].…”

We examined and compared heavy metals bioaccumulation in Cyprinus carpio and Labeo rohita netted from Sardaryab, a tributary of River Kabul. By using atomic absorption spectrometry we assessed different organs including livers, gills, and muscles. Metals studied were chromium, iron, zinc, lead, and copper. Livers of both species showed higher concentrations of metals while muscles showed the least amount. Chromium and iron were the highly concentrated metals in the gills and livers of both species. A quantity of 0.154 ± 0.011, 0.199 ± 0.0079, and 0.024 ± 0.008 μg/g of chromium was found in the gills, livers, and muscles of Cyprinus carpio, respectively. Similarly, the gills, liver, and muscles of Labeo rohita contained 0.133 ± 0.008, 0.165 ± 0.01, and 0.019 ± 0.006 μg/g of Cr, respectively. Iron was highest in carp in the range of 0.086 ± 0.01 in gills and 0.067 ± 0.011 μg/g in muscles, comparatively. All the studied metals were found within the US recommended daily dietary allowances (RDA) limits; hence no immediate risk in their consumption for human was found. The data showed that Cyprinus carpio being omnivorous and bottom feeder stored higher concentrations of metals as compared to Labeo rohita.

“…Heavy metals deteriorate the ecological balance of the aquatic environment [1, 19–21]. Because fishes are at the end of aquatic trophic level they have higher tendency to accumulate heavy metals in their body (Jakimiska et al, 2011).…”

“…The highest bioaccumulation of heavy metals in gills as reported in several studies could be attributed to two main reasons. First, because of its thinnest epithelium among all the organs of the body through which metals can easily pass (Mastan, 2014) and second, the surfaces of the gills are negatively charged whereas, the metal ions are positive charges due to which there is high affinity to the bonding between them (Siraj et al, 2016. The bioaccumulation of heavy metals in the freshwater fish muscles is especially of concern because these are rich protein sources and are vastly consumed as human food (Tunçsoy et al, 2016). As indicated by the results, the present study infers the accumulation of the lowest amount of lead in the muscles compared to the other organs, and several studies report the same.…”

Bioaccumulation of lead in different organs of Ctenopharyngodon Idella (grass fish) and Tor putitora (Mahseer) fish

Bioaccumulation of toxic heavy metals in the human body can give rise to adverse health effects, the severity of which depends upon their dosage and duration of exposure. In this study, yearlings of two different species of edible fish, i.e., Tor putitora (Mahseer) and Ctenopharyngodon Idella (grass carp), were exposed to different concentrations of lead nitrate in a controlled environment of aquarium for three different lengths of duration (14, 28, and 60 days). The bioaccumulation of lead in different organs, including gills, skin, muscles, liver, intestine, and swim bladder of the fish, was assessed using atomic absorption spectrometry. Generally, the highest lead concentration was observed in the gills and lowest in the muscles for both species at each experimental dosage and duration. In 14-days exposure, the relative pattern of bioaccumulation in different organs was observed as gill > liver > skin > intestine > swim bladder > muscle for both fish species. Similarly, the pattern of bioaccumulation observed in 28-days exposure was as: gill > liver > intestine > skin > swim bladder > muscle in both species. Whereas, pattern in 60-days exposure was observed as gill > liver > intestine > swim bladder > muscle > skin. The data shows that grass carp had stored higher concentrations of lead than Mahseer, which may be attributed to the fact that they are omnivorous. Furthermore, the lowest bioaccumulation was recorded in the muscles until the 56th day of the exposure, after which the concentration steadily increased in the muscles. The observed pattern highlights the importance of exposure’s duration to lead; chronic exposure could result in its bioaccumulation at toxic concentrations in the muscles, which is particularly of concern because the fish muscles are heavily consumed as food worldwide.

“…Heavy metals like Copper, Lead, Mercury, Cadmium, Nickel and Chromium are mainly responsible for water pollution. Heavy metal contamination may cause devastating effects on the ecological balance of the recipient environment and its diversity of aquatic organisms (Mastan, 2014). Metals have the tendency to accumulate in various organs of the aquatic organisms, especially fish, which in turn may enter into the human metabolism through consumption causing serious health hazards (Yousafzai et al, 2009).…”

Heavy metal pollution is a global problem growing at an alarming rate and aquatic organisms arecontinuously exposed to elevated levels of metals seriously threatening the whole ecosystem.The objective of the present study is to determine the bioaccumulation of heavy metals insome organs of the freshwater fish, Clarias batrachus exposed to heavy metal, nickel andchromium contaminated water. The experimental fish was exposed to Cr and Ni at sublethalconcentrations for periods of 30 days. The result revealed that the concentration of both heavymetals was significantly high in the gill, kidney and liver of metal exposed fish in comparison tothe tissues of respective organs of control fish. The order accumulation of heavy metal, nickelin the tissues was liver>kidney>gills whereas chromium also accumulate in the order liver>Kidney> gill.
