“…Environmental factors such as salinity influence metal dynamics in the environment and its toxicity [15,34,58]. In freshwater animals, which are hyperosmotic, exhibiting body ions at higher concentrations than the environment, Cu impairs sodium uptake by the gills, preventing osmotic homeostasis.…”

“…Cu, like Cd, does not biomagnify along the entire chain, with the exception at low trophic levels, but as a nondegradable toxic pollutant [55,59,60], it accumulates in both the environment and in animals (e.g., lobsters [21]; crabs [34]; shrimp [58] and humans [61]). Baki et al [17] identified that when compared to fish, crustaceans exhibit higher Cu concentrations, with crabs containing higher values than prawns, followed by lobsters.…”

“…In addition, Cu can lead to the production of reactive oxygen species, resulting in lipid peroxidation, DNA damage, changes in sulfide groups and in calcium homeostasis [19]. An increase in protein and energy catabolism, inhibition of ionic transport proteins in gills, and alterations in the activity of enzymes in the glycolytic pathway in the Krebs cycle were also identified [34]. The accumulation of this metal was also responsible for increased heart rate, loss of cellular integrity, immune response and enzyme function, as well as endocrine disruption.…”

“…Menezes et al [34] evaluated the effects of Cu exposure on the metabolism of blue crabs (Callinectes sapidus) in different osmotic situations, reporting that Cu exposure increased oxygen consumption throughout the body when the animals were subjected to low salinity. This is due to the fact that Cu is considered a potent toxic agent against ion-regulatory processes, inhibiting the expression of ionoregulatory proteins.…”

“…The main metals, reported in several toxicity studies on animals, humans, and the environment, are Al, the metalloid As, Cd, Cr, Cu, Pb, Hg, Ni, and Ag [5,16,[23][24][25][26][27]. In the longterm, in animals, the accumulation of these metals whether essential in high concentrations or nonessential, can cause several types of damage, mainly to the respiratory [20,28] and gastrointestinal [29,30] systems, as well as affecting reproductive capacity [31,32] and interfering with animal metabolism [33,34]. In humans, these metals may lead to liver, kidney, central nervous system, mucus tissue, intestinal tract, and reproductive system damage, and are considered a severe public health issue [5].…”

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.

Acute metabolic responses of two marine brachyuran crabs to dilute seawater: The aerobic cost of hyper regulation

Hepatus pudibundus ("flecked box crab") is a stenohaline osmoconfomer, and restricted to marine habitats. Callinectes danae ("swimming crab Dana") lives in coastal/estuarine waters and is a weak hyper regulator. There is no consensus on which strategy is more expensive metabolically face salinity challenges: conformation with higher dependence on cell volume regulation, or hyper regulation, alleviating the need for intense cell volume regulation. Crabs were probed for their acute response to dilute seawater through exposures to salinities 35‰, 30‰, 25‰, and 20‰ for 2, 4, and 6 h. Hemolymph osmolality, lactate, and ions (chloride, sodium, magnesium, potassium) were assayed, as well as muscle water content.Water dissolved oxygen, ammonia, and pH levels were also measured. H. pudibundus conformed for osmolality and displayed increase in muscle hydration along the decrease in salinity down to 25‰, while C. danae efficiently maintained hemolymph osmo ionic stability, consumed more oxygen, acidified more the water, and released more ammonia. In 25‰, both species spent energy: H. pudibundus putatively controlling cell volume, and C. danae regulating hemolymph concentrations. In 20‰, H. pudibundus closed itself, avoiding the contact of the interface epithelia with the external environment and producing much lactate, whereas C. danae spent more energy (aerobic) in extracellular osmo ionic stability. Under these conditions, anisosmotic extracellular regulation (together with additional cell volume regulation) is more oxygen consuming than osmoconformation with a putatively more intense challenge to cell volume. The exposure to hyposalinity limits the occupation of estuarine environments by H. pudibundus in short and middle term.
