“…It has a high potential for heavy metal deposition. In the present study, it was found that the amount of lead accumulated in bivalves in vivo is quite high (Sánchez-Marín et al, 2019). In vivo experimental study shows that cadmium poisoning causes a serious degeneration in kidney epithelial cells in addition to the expansion and adhesion of secondary lamellae in the gills, as well as in fish fed with cadmium-contaminated fish food (Beširović et al, 2011).…”

“…Environmental pollution has been increasing day by day and threatening the lives of many living species including humans. The rapid development in the industry not only threatens the lives of land and aquatic organisms but also causes toxicity in humans who consume these organisms as foodstuffs and other aquatic organisms, which are the food source of humans (Sánchez-Marín et al, 2019). The Çanakkale Strait, an important route for trade ship crossings, has been exposed to environmental pollution for years.…”

Ruditapes decussatus (Linnaeus, 1758) belongs to the Veneridae family is given as nutrients to rats. R. decussatus was collected from three different locations from the Çanakkale Strait. Twenty-four male Wistar Albino rats (270-310 g) were used in the study. There were six rats for each experimental group. The first group fed with standard rat feed, the second group fed with 80% R. decussatus + 20% standard rat feed daily; the third group fed with 80% R. decussatus + 20% standard rat feed every other day, the fourth group fed with 80% R. decussatus + 80% standard rat feed every three days. After routine histopathological follow-up, gastric tissue samples of all subjects were stained and examined under the light microscope. There were no histopathological findings in the gastric tissues of rats in the control group of hematoxylin-eosin staining. In gastric tissues of rats fed with R. decussatus, chronic gastritis caused by mononuclear inflammation between lamina propria and occasional gastric glands was noted. It was observed that inflammation severity and distribution were high especially in tissues of rats fed with R. decussatus every day. It was observed that the most commonly consumed shellfish may cause pathological picture on the digestive system of rats. As a result, increasing environmental pollution threatens the life of water as well as land life, and the consumption of living organisms exposed to polluted environments continues to threaten and affect human life. It is important to pay attention to the conditions under which the consumed products are collected and how they are collected.

“…Because, if not removed, there is a migration from the intestines to the muscle tissue, which prevents the value in the muscles to be drawn to the limit values (16). Previous studies on mussels that had been exposed to heavy metals for a long time and then analyzed by taking various tissues from mussels have reported that these organisms can accumulate these heavy metals in tissues, including muscle, excretory, or even genital organs (17,18). Analysis results for the muscle tissue of the clam determined that the heavy metal accumulation was above the reference limits.…”

One of the most important threats for living things in aquatic ecosystems is environmental pollution. The changes in water quality caused by environmental pollution also reduce the quality of life for organisms in the environment. Among these, the crustaceans which are most affected by the negative changes of environment, fed by the filtration method, are seen as pollution indicator. The consumption of these creatures reaches all steps of the pyramid, especially humans, through the food chain. People who frequently use seafood in their diets may be affected by these negative changes. Heavy metal contents of the clams obtained from Dardanelles were determined by the ICPOES. Twenty-four female Wistar albino rats were fed for 30 days with the experimental diet using clams (Pecten maximus), which was dried and formed into pellets and added to the food in certain proportions. At the end of the study, the subjects were sacrificed under anesthesia, liver tissues were taken, and histochemical examination was performed. TUNEL method was performed to detect apoptotic activity, and immunohistochemical staining with TNF-α and NF-κB antibodies to determine inflammation. Concluding from the results, it was observed that the degeneration of vital digestive system tissues such as liver was inevitable in living creatures that frequently consume seafood obtained from unhealthy environment in their daily diets. The high analysis values of the heavy metal (P. maximus) in food additive can be considered as a reason for histopathological results.

“…This matches the observations of Sánchez-Marín and Beiras (2017), who found that lead-rich granules accumulated in the clam D. exoleta are not available for transfer into the prawn Palaemon serratus. However, the composition of these granules in mollusks, as well as the speciation of lead influence its bioavailability, transfer, and accumulation (Sánchez-Marín et al 2019). Also, the supplied diet may not favor metal accumulation in crustaceans because it may accumulate metals mainly through gills across epithelial surfaces, since they are an important organ in breathing and osmoregulation (Soegianto et al 2016).…”

Aquatic ecosystems suffer alterations by the input of several pollutants as potentially toxic elements which interact with the planktonic community with likelihood of bioconcentration, bioaccumulation, and biomagnification through the trophic chains despite the fact of being in low concentrations. The goal of this study involves assessing the toxicity, bioaccumulation, and transfer of the lead under controlled laboratory conditions by estimating the bioconcentration factor (BCF) and bioaccumulation factor (BAF) in organisms usually used in aquaculture, as Nannochloropsis oculata microalgae, Brachionus plicatilis rotifer, and the Malaysian prawn Macrobrachium rosenbergii. We assessed toxicity, bioconcentration, and transfer of the lead from the microalgae to higher trophic levels, the rotifer, and the prawn larvae. We performed three bioassays: (1) lead-exposed microalgae, (2) rotifer fed with lead-exposed microalgae, and (3) prawn larvae fed with either lead-exposed microalgae or rotifers fed with these microalgae. The toxicity endpoints were obtained for microalgae. The concentration of the lead in all organisms was analyzed by atomic absorption spectrophotometry for estimating BCF and BAF values. The endpoints No Observed Effect Concentration (NOEC) and Effective Concentration 50 (EC50) are 1 and 5.42 mg/L, respectively, for N. oculata. The BCF in the microalgae decreases as lead concentration increases. A BAF of 2948 in rotifers, and a BAF of 42.1 in prawns were obtained. In conclusion, lead can concentrate in microalgae, transfer, and accumulate through consumption toward the consecutive trophic levels, but not among invertebrates due to their detoxification mechanisms.
