“…The ratios between the lead concentrations in carapace to those in muscle for WS 60 , WS 80 and TS were 4.81, 2.47, and 1.35, respectively. Those ratios are in accordance to the same ratios (0.71 -5.43), as in [7]. The lead concentrations in carapace may be influenced by molting processes such as reported for fiddler crabs Ucapugnaxby [8]thatmolting reduces the body burden.…”

Abstract-The lead concentrations in muscles and carapace of white shrimp (Litopenaeus vannamei) fromPaliyan village, Temon district, Kulon Progo county, Yogyakarta Special Province in Indonesia and those of tiger shrimp (Penaeus monodon) bought in a grocery store in Yogyakarta were determined and compared to assses bioaccumulation and food safety.Ten samples of 40-day-old white shrimp composites (n=8), ten samples of 60-day-old White shrimp composites (n =5), ten samples of 80 day-old white shrimp composites (n=5), and ten samples of tiger shrimp composites (n=2) were collected and analyzed for Pb concentrations using Atomic Absorption Spectrophotometer. The mean concentration of Pb in 40-day-old white shrimps were below the detection limit of 0.05 µg/g d.w. No significant differences was found between the mean concentrations of Pb in muscles of 60-day-old (1.71 ± 0.74) and those of 80-day-old (1.84 ± 0.30 µg/g d.w.) white shrimps. However, significant differences (p < 0.05) were found between the mean concentrations of Pb in carapace of 60-day-old (8.22 ± 3.35) and those of 80-day-old (4.55 ± 1.03 µg/g d.w.) white shrimps. The mean of lead concentrations in shrimps in this study (0.25 -0.41 µg/g w.w.) were lower than the recommended limit (0.50 µg/g w.w.). Similarly, the average daily intake of Pb through shrimp consumption was 0.39-13.39 µg/person/day and was relatively lower than the recommended value of 12,86 µg/person/day. Based on the results, it can be concluded that the shrimps analyzed in this study were safe for human consumption.

“…result of their direct exposure to the surrounding environment, the gills of crustaceans also tend to accumulate high concentrations of certain metals, such as Cd [12] and Pb. [13] While the gills were found to accumulate a substantial amount of metals in the present study, it must be noted that bioaccumulation is based on multiple factors and depends heavily on exposure time and metal concentration. [14,15] As such, different tissues may be found to accumulate higher concentrations of the same metal in different studies.…”

“…Female crayfish of different species were found to accumulate less As, Ni and Cd in their gills when tested during the reproductive season, [16,18] which may suggest that these metals are sequestered within the eggs. [19] Outside the reproductive season, sex has a relatively minor effect on metal accumulation trends, which may [20] or may not [13] be statistically significant.…”

The accumulations of Al, Cd, Cr, Cu, Fe, Ni, Pb and Zn in the exoskeleton, gills, hepatopancreas and abdominal muscles of crayfish Astacus leptodactylus (Eschscholtz, 1823) were determined. The strongest correlation observed was between Cr and Ni in the gills (r = 0.904); moderate to strong correlations between Al, Cr, Fe, Ni and Cu were also observed in gill tissue. Disregarding the gills, the strongest correlation was found between Cu and Zn in the hepatopancreas (r = 0.808); the correlation between these two metals might have been a result of metallothionein activity. The accumulation of Pb was found to correlate with that of Cd in the exoskeleton, Cd and Zn in the gills, Zn and Cu in the hepatopancreas and Cu in the abdominal muscle. None of these correlations were present in lakewater and sediment samples, suggesting that the crayfish metabolism may be responsible for the co-accumulation of metal-metal pairs. As all correlations in non-gill tissues are observed between divalent metals, a shared transporter such as divalent metal transporter 1 might be involved in the accumulation of these metals.

“…Environmental factors such as high temperatures and low pH and low salinity are attributed to the higher absorption and bioaccumulation of Pb in crustaceans [73,74]. Aquatic animals, such as crustaceans, acquire Pb through water and food, with very low concentrations still considered potently toxic, since this is a nonessential metal displaying high cytotoxic and bioaccumulative capacity [1,70,75,76]. Baki et al [17] identified higher Pb concentrations in shrimp when compared to other crustaceans such as lobster and crab, as well as fish.…”

“…Baki et al [17] identified higher Pb concentrations in shrimp when compared to other crustaceans such as lobster and crab, as well as fish. Studies point to hepatopancreas, gills and the reproductive system as important Pb targets [73,75,77,78] in animals, while in humans the main target tissues are the kidneys, followed by the liver and other soft tissues such as heart and brain, with the nervous system being the most vulnerable organ [55].…”

Metals, many of which are potentially toxic, are present in the aquatic environment originated from both natural and anthropogenic sources. In these ecosystems, these elements are mostly deposited in the sediment, followed by water dissolution, potentially contaminating resident biota. Among several aquatic animals, crustaceans are considered excellent bioindicators, as they live in close contact with contaminated sediment. The accumulation of metal, whether they are classified as essential, when in excessive quantities or nonessential, not only cause damage to the health of these animals, but also to the man who consumes seafood. Among the main toxic elements to animal and human health are aluminum, arsenic, cadmium, chromium, copper, lead, mercury, nickel and silver. In this context, this systematic review aimed to investigate the dynamics of these metals in water, the main bioaccumulative tissues in crustaceans, the effects of these contaminants on animal and human health, and the regulatory limits for these metals worldwide. A total of 91 articles were selected for this review, and an additional 68 articles not found in the three assessed databases were considered essential and included, totaling 159 articles published between 2010 and 2020. Our results indicate that both chemical speciation and abiotic factors such as pH, oxygen and salinity in aquatic environments affect element bioavailability, dynamics, and toxicity. Among crustaceans, crabs are considered the main bioindicator biological system, with the hepatopancreas appearing as the main bioaccumulator organ. Studies indicate that exposure to these elements may result in nervous, respiratory, and reproductive system effects in both animals and humans. Finally, many studies indicate that the concentrations of these elements in crustaceans intended for human consumption exceed limits established by international organizations, both with regard to seafood metal contents and well as daily, weekly, or monthly intake limits set for humans, indicating consumer health risks.
