“…The bioaccumulation of heavy metals in animal tissues occurs as a result of competing rates of chemical uptake and excretion. Accumulation of metals will therefore occur when the rate of uptake is higher than that of excretion (Otitoloju et al, 2009). The accumulation of heavy metals in aquatic systems suggests that fish may serve as a useful indicator for contaminating metals in aquatic systems, because they respond with great sensitivity to changes in the aquatic environment (Boening, 1999; Mondon et al, 2001; Vinodhini and Narayanan, 2008a).…”

Since toxicity is based on the effect that a toxicant produces at a target site within an organism, establishing the relationship between the concentration of substance at the target site and the subsequent toxic effect can provide a tool for predicting toxicity. This article aims to investigate the patterns of bioaccumulation and elimination of nickel in the selected organs of black fish (Capoeta fusca) exposed to two treatments of nickel (4.5 and 12.7 mg/L) for a period of 30 days. Nickel was assayed using Shimadzu AA 680 atomic absorption spectrophotometer, and the results were given as μg/g wet weight. This finding showed that the accumulation patterns of nickel, for lower sub-lethal (LSL) and higher sub-lethal (HSL) concentrations of nickel, are in the following order: gill > liver > muscle > skin. The elimination patterns of nickel are in the following order: gill > skin > muscle > liver, for LSL concentration, and gill > skin > liver > muscle, for HSL concentration of nickel. The results show that the target organ for accumulation and elimination of nickel is gill.

“…In addition, it is also toxic to humans, plants and animals, and has been frequently detected in the environment. The addition of Pb in fuel has strongly contributed to the increase of its occurrence in the atmosphere, and wet and dry deposition into waterbodies, where uptake by aquatic organisms can occur, leading to accumulation in animal tissues (Otitoloju et al, 2009). Kakkar and Jaffery (2005) reported the transfer of Pb between a primary (Daphnia magna) and a secondary consumer (Poecilia reticulum), showing potential biomagnification and the inherent public health risk of this metal.…”

This study aimed to assess the bioaccumulation of Pb and induction of metallothionein-like proteins (MT) in Callinectes danae through single and combined dietary and waterborne exposures. Male C. danae individuals were collected in the south area of the Cananéia-Iguape-Peruíbe Protected Area (APA-CIP), in São Paulo State, Brazil. After an acclimatization period, exposure assays were performed during 7 and 14 days, at two Pb concentrations (0.5 e 2.0 µg/g) in 4 treatments: 1) control; 2) contaminated water only; 3) contaminated food only; 4) contaminated water and food. The results indicate that C. danae is highly tolerant to Pb exposure at the evaluated concentrations. In gills, Pb bioaccumulation is more dependent of water efflux and time of exposure (higher Pb values). However, pathways act simultaneously in the induction of MT expression in this tissue. The decreases in Pb accumulation in the combined treatments and MT increases after 14 days in gills suggests that these proteins play a detoxification function in the presence of Pb. In hepatopancreas, depending on the predominance of a certain pathway or combined pathways, accumulation occured at different times. For muscle tissue, bioaccumulation was observed due to contaminated water exposure, but not dietary exposure, probably because Pb concentrations were low.

“…Since the gills are not edible, bioaccumulation in them will not affect humans through consumption. Otitoloju et al [31] reported the toxicity of Copper and Lead to C. amnicola; sublethal concenterations of these trace metals resulted in their bioaccumulation in the tissues with gill>muscle>hepatopancreas, and a reduction in the weight of the exposed blue crab over a 14 day period was also reported. This suggests that the gills C. amnicola can be used to evaluate the bioavailabtlity of Lead in the aquatic environment.…”

Aspects of the biology of an economically important crab, Callinectes amnicola (De Rochebrune, 1883), were studied to determine the growth pattern, condition factor, ectoparasitic load and trace metal (Manganese, Zinc, Lead, Cadmium and Mercury) levels. Water and sediment samples were also collected for trace metal analysis and to determine bioconcentration factor in crab samples. Males recorded significantly longer carapace (p<0.05) and were heavier (p<0.01) compared to female crabs. C. amnicola showed negative allometric growth (p<0.05; b<3) regardless of sex or size using carapace width; however, with carapace length, the crab exhibited isometric growth for male (p>0.05; b=3) and positive allometric growth for female and sex combined (p<0.05; b>3). Males were better conditioned than females and condition increased with size for males. Only male C. amnicola were infected with ectoparasitic barnacles with a prevalence of 13.46%. The ectoparasites select better conditioned crabs for infestation and this colonization subsequently reduces the condition with increased size. Mean trace metal values recorded for C. amnicola, water and sediment were in the order Manganese>Zinc>Lead>Cadmium>Mercury. The gills had the highest mean values for all the trace metals measured and also had the highest bioconcentration factor with lead recording a factor of 42 from water. However, the edible portion such as muscle, chelipeds and carapace bioaccumulated Manganese, Zinc and Cadmium from water by a maximum factor of 4. Carapace length, growth pattern, condition factor and ectoparasitic infestation may be used to discriminate among sexes of C. amnicola. This study shows relatively low concentrations of trace metals compared to the WHO limits and C. amnicola may be used to monitor the bioavailability of trace metals in the Lagos Lagoon.
