“…It has been demonstrated that metal accumulation in fish tissue is influenced by a number of abiotic factors such as biological habitat, chemical form, temperature, salinity, pH, dissolved oxygen concentration, water transparency etc. [7] together with biotic ones such as species, sex, body mass, age, physiologic conditions and nourishment sources [66]. Therefore, predicting a rate of metal bioaccumulation in fish tissue is difficult as it depends on the various factors described [67].…”

“…One of these species is Mullets (Mullus sp.) [6] which has been recommended as a monitoring species for metal pollution [7,8]. Other typical Mediterranean species used as sentinel fish are the Sea bass which is also the species mostly produced in aquaculture of Mediterranean areas [9] and the Sea bream which is widely distributed throughout the entire Mediterranean Sea and is selected for its native sandy costal habitat [10].…”

Cadmium (Cd), lead (Pb) and mercury (Hg) are toxic metals with increasing interest due to their tendency to bioaccumulate in fish tissue which may pose a threat to human health via fish consumption. This review of the recent literature on Cd, Pb, Hg levels summarizes data of fish biomonitoring studies in the Mediterranean Sea in order to determine potential risks due to dietary intake of metals. The analytical methods applied are described, with Atomic Absorption Spectroscopy and Inductively Coupled Plasma Mass Spectroscopy being the most popular. Most of the literature reviewed is focused on the Eastern Mediterranean. Results from the studies indicate that metals mostly accumulate in liver, followed by muscle. Although there are few studies reporting metal levels in fish exceeding the maximum residue levels (MRLs), the bulk of the studies cite levels below the MRLs. The hazard index (HI) of fish consumption, namely the ratio of estimated weekly intake to provisional tolerable weekly intake (EWI/PTWI) was estimated for adult consumers and no risk emerged. The EWI/PTWI ratios of lead and mercury for Italy 418(0.14 and 0.22 respectively) represent the highest HI levels estimated. In view of maximizing the benefits while minimizing the risks of fish consumption, a more detailed fish-specific database on intakes for consumers is required and extended bimonitoring in as many regions as possible.

“…Patella caerulea and other gastropod mollusks are extensively used in monitoring programs in the marine environment due to their ability to accumulate heavy metals (Bu-Olayan and Thomas 2001;Campanella et al 2001;Storelli and Marcotrigiano 2005). The gastropod P. caerulea is among the commonest inhabitants of rocky shores in the whole Mediterranean basin (Storelli and Marcotrigiano 2005).…”

The concentrations of Cd, Cu, Zn, Fe, Pb, Ni, and Co were measured in gastropod mollusks Patella caerulea in the Mediterranean area. The organisms were collected at two coastal sites in Iskenderun Gulf during winter, spring, summer, and autumn 2008. Samples of the digestive gland, gill, and muscle were analyzed for heavy metals. The aim of study is to determine heavy metal levels in tissues of P. caerulea in different locations. Tissues of P. caerulea from the polluted site showed metal concentrations appreciably higher than unpolluted organisms. The highest metal levels were registered in the digestive gland of P. caerulea. Generally, digestive gland and gills showed higher metal concentrations than muscle. The average concentrations of heavy metals analyzed exhibited the following decreasing order: Fe>Zn>Cu>Ni>Cd>Pb>Co for both stations 1 and 2. Seasonal changes in metal concentrations were observed in the tissues of P. caerulea from a polluted and an unpolluted population.

“…Feeding habits of fish species are strongly related to seasonal variations in accumulation patterns of metals [13]. In contrast to our findings, metal concentrations in fishes from the Seyhan River of Turkey rise from autumn to summer [22]. Stream conditions, contamination levels, water physico chemical properties, and other environmental factors play a role in seasonal variations in metal accumulation, which strongly affects heavy metal bioavailability [23].…”

The deterioration of aquatic ecosystems as inflicted by heavy metals is looming large, hence the issue is getting momentum globally. Heavy metals are unabatedly released into aquatic ecosystems from anthropogenic sources such as mining of metals, urban and sewage wastes, industrial effluents, and metals by way of agricultural drainage, as well as natural sources such as geological weathering of rocks and atmospheric deposition [1]. Heavy metals are persistent, bio accumulative, and non-biodegradable in Pol. J. Environ. Stud. Vol. 26, No. 2 (2017), 627-633 AbstractThe purpose of this study was to evaluate the accumulation of heavy metals in the liver, skin, gills, and muscles of two freshwater edible fish species (Labeo rohita and Wallago attu) collected from Taunsa barrage of the Indus River in Pakistan. Fish samples were collected on a seasonal basis and were analyzed by atomic absorption spectroscopy. Gills and liver accumulated relatively higher heavy metal concentrations. All fish organs accumulated the highest metal content in winter and the lowest in summer. Heavy metals accumulated in the order Fe>Zn>Ni>Cu>Pb>Cr>As in the body of Labeo rohita and the tissues with the abundance were liver>gills>skin>muscles. Similarly, the sequence of heavy metal accumulation in Wallago attu was Fe>Zn>Cu>Ni>Cr>Pb>As, and the targeted tissues were gills>liver>skin>muscles. Heavy metal bioaccumulation was different in both species. Fe was the highest and As was the least accumulated heavy metal in both of these fish species. The tissues of Wallago attu accumulated higher concentrations of Ni (83%), Cu (64%), Cr (50%), Fe (2.95%), and Zn (26%) compared to tissues of Labeo rohita. However, Pb (67%) and As (22%) accumulation in tissues of Labeo rohita were higher compared to their concentrations in tissues of Wallago attu. Overall metal burden was 10% higher in Wallago attu compared to Labeo rohita. Heavy metal concentration in fish tissues were compared with FAO threshold values.
