Some Heavy Metals Accumulation in Tissues in Capoeta umbla (Heckel, 1843) from Uzuncayir Dam Lake (Tunceli, Turkey)

Abstract

Concentrations of metals were determined in the gills, liver, kidney, heart and muscle in Capoeta umbla caught from six stations from the Munzur River system. Metal concentrations in the tissues tended to vary significantly among stations (p < 0.05). Liver (Cu, 10.10 ± 0.23-23.03 ± 9.37 ppm; Zn, 14.67 ± 3.01-21.82 ± 2.39 ppm; Cd, 18.04 ± 4.56-52.69 ± 10.65 ppb and Fe, 28.87 ± 6.78-115.11 ± 34.87 ppm) and kidney (Cu, 1.80 ± 0.25-3.70 ± 0.62 ppm; Zn, 20.81 ± 0.37-29.36 ± 0.70 ppm; Cd, 132.06 ± 5.29-639.51 ± 20.14 ppb and Fe, 24.40 ± 1.98-59.39 ± 1.97 ppm) tissues showed higher metal concentrations than other tissues. It seems that metal contamination in the river is too high for the health of fish and the people who eat them. The geographical locations of catch, season, nature of diet, and the size of fish used for analyses might lead to different metal concentration in the same fish species.

Metal bioaccumulation in common carp and rudd from the Topolnitsa reservoir, Bulgaria

“…Fish are exposed to metals through water and food (13). Metal bioaccumulation depends on many factors such as fish species, age, tissue, season, pH, water temperature, and hardness (14). In teleosts, the most common tissues used in toxicology studies are the gills, liver, kidney, and muscles (15,16).…”

Temporal Variation of Metals in Water, Sediment and Tissues of the European Chup (Squalius cephalus L.)

“…In terms of the use of drain water for irrigation and the organisms living in the environment for drain water discharge, especially trace elements in drain water are important in terms of public health, because trace elements are directly and indirectly transferred via the food chain. More importantly, the combination of toxic organic wastes with metals or the changing of them into other compounds can cause problems due to the formation of more toxic wastes (Ural et al 2012). Although heavy metals are found at low levels in water, they can reach significant levels in sediment and aqueous biota.…”

Bioaccumulation and elimination rate of cobalt in Capoeta fusca under controlled conditions

“…Metals are not biologically degradable and some have toxic effects on organisms; therefore their pollution in the natural environment is a worldwide problem (Mansouri et al, 2012a;Ural et al, 2011). These pollutants have the ability to accumulate in the organs of aquatic organisms (Palaniappan and Karthikeyan, 2009), which is known as bioaccumulation.…”

“…These pollutants have the ability to accumulate in the organs of aquatic organisms (Palaniappan and Karthikeyan, 2009), which is known as bioaccumulation. Three different aspects of bioaccumulation of metals are: the amount of toxin ingested by the organisms; the pattern in which the metals are distributed through different organs; and the extent to which the metals remain in each one of the organs under consideration (Ural et al, 2011;Senthil Murugan et al, 2008). These aspects highlight the great importance of studying bioaccumulation potential of metal pollutants in organisms (Palaniappan and Karthikeyan, 2009).…”

“…Fish species are often at the top of aquatic food chain and can accumulate heavy metals from the environment in high concentrations in their bodies. Thus, fish species can be used as bio-indicators of heavy metal pollution in the aquatic environment (Ural et al, 2011;Gul et al, 2011;Mieiro et al, 2011). Fish is an important part of the human diet and it is important to know the concentrations of metals in fish tissue.…”
