“…Whole body burdens of Cd in mummichogs were strongly associated with the trophically available fraction of Cd (TAM-[Cd]) only in P. pugio in 2004; no relationship between TAM- [Cd] in N. acuminata and Cd whole body burdens in mummichogs was found. In general, many fishes are known to efficiently eliminate a large amount of Cd ingested with the diet (e.g., Harrison and Curtis, 1992;Seebaugh et al, 2005). Previous feeding experiments using the reference population (Lemon Creek) have demonstrated that mummichogs are able to eliminate more than 90% of ingested Cd in P. pugio (Seebaugh et al, 2005).…”

It is thus not surprising that the populations of mummichogs from chronically polluted sites can also eliminate the majority of trophically available Cd in ingested prey.…”

Intracellular partitioning of trace metals is critical to metal tolerance in aquatic organisms and may also influence metal trophic transfer in ecosystems. In this study, we tested the relevance of metal (Cd, Cu, Pb, and Zn) intracellular partitioning in prey as an indicator of metal trophic availability to benthic forage fish, mummichogs (Fundulus heteroclitus), in chronically metal-polluted salt marshes in New York, USA. Two common prey of mummichogs in the study area, Palaemonetes pugio and Nereis acuminata, generally stored increasingly higher proportions of non-essential metals (particularly Pb) in insoluble (less trophically available) cellular components, as the whole body burdens increased. In contrast, intracellular partitioning of essential metals (Cu and Zn) in invertebrate prey varied relatively little among sites. Differential Cd and Pb intracellular partitioning patterns within P. pugio among sites were significantly associated with Cd and Pb whole body burdens in mummichogs, respectively (i.e., prey-driven bioreduction of metals), while bioaccumulation of Cu and Zn in mummichogs was similar among populations. The findings in this study suggest that metal intracellular partitioning within prey may be partially responsible for metal trophic availability to a predator in metal-polluted habitats, while there was also evidence that some predator-dependent processes may offset differential trophic availabilities from prey.

“…Since enhanced Hg partitioning to the TAM compartment in worms was not observed, the approximately 1.50-fold increase in shrimp Hg concentrations between the 0.02 and 0.03 lM Hg treatments (i.e., with respect to worm exposure concentration) may be related to variability in digestion rather than bioenhancement from metal repartitioning in prey (Seebaugh et al 2005). Worms used for grass shrimp pre-exposures were not analyzed for Hg associated with specific subcellular fractions defined as TAM (metallothionein-like proteins, enzymes, and organelles) or non-TAM (cellular debris and other insoluble components) by Wallace and Luoma (2003).…”

Grass shrimp Palaemonetes pugio were fed mercury (Hg)-contaminated oligochaetes for 15 days and analyzed for Hg, cadmium (Cd), and carbon assimilation efficiencies (AE) as well as toxicological end points related to digestion. Disproportionate increases in stable Hg concentrations in shrimp did not appear to be related to partitioning to trophically available Hg in worms. Hg AE by pre-exposed shrimp reached a plateau (approximately 53 %), whereas Cd AE varied (approximately 40-60 %) in a manner that was not dose-dependent. Carbon AE did not differ among treatments (approximately 69 %). Gut residence time was not impacted significantly by Hg pre-exposure (grand median approximately 465 min), however, there was a trend between curves showing percentages of individuals with markers in feces over time versus treatment. Feces-elimination rate did not vary with dietary pre-exposure. Extracellular protease activity varied approximately 1.9-fold but did not exhibit dose-dependency. pH increased over the range of Hg pre-exposures within the anterior (pH approximately 5.33-6.51) and posterior (pH approximately 5.29-6.25) regions of the cardiac proventriculus and Hg assimilation exhibited a negative relationship to hydrogen ion concentrations. The results of this study indicate that previous Hg ingestion can elicit post-assimilatory impacts on grass shrimp digestive physiology, which may, in turn, influence Hg assimilation during subsequent digestive cycles.

“…Several studies have reported the concentration and toxicity of cadmium in shrimps (Páez-Osuna and Ruíz-Fernández, 1995b;Páez-Osuna and Tron-Mayen, 1996;Vanegas et al, 1997;Soegianto et al, 1999;Pourang and Amini, 2001;Kargin et al, 2001;Pourang et al, 2004;Wu and Chen, 2004;Seebaugh et al, 2005;Santos et al, 2013). The Cd concentrations in the shrimp body depend mainly on their levels in the environment since this element is not essential in the biochemical and physiological processes of this animal (Ruelas-Inzunza and Páez-Osuna, 2004).…”

In this study, concentrations of trace elements in tissues of shrimp species (Litopenaeus vannamei) from farming and zone natural coastal located in the northeastern Brazil were investigated. The elements determination was performed by optical emission spectrometry with inductively coupled plasma (ICP OES). The following ranges of concentrations in the tissues were obtained in µg g -1 dry weight: Al: 13. . The shrimp muscle can be a good iron source (about 88.9 mg -1 g dry weight). The distribution of Se concentration in tissues showed much variation between locations, and the concentration levels found in shrimp muscles of wild samples were high, where its levels in 67% of muscle and 50% of others tissues samples exceeded the ANVISA limit, indicating evidence of selenium bioaccumulation. Distribuição de elementos traço em tecidos do camarão Litopenaeus vannamei (Boone, 1931) da Bahia, Brasil ResumoEsse estudo teve como objetivo avaliar as concentrações de elementos traço em tecidos da espécie de camarão Litopenaeus vannamei coletadas da zona costeira e de carciniculturas localizadas no nordeste do Brasil. Os elementos químicos foram determinados por espectrômetro de emissão óptica com plasma indutivamente acoplado (ICP OES). Foram encontradas as seguintes faixas de concentrações desses elementos nos tecidos (em mg g -1 peso seco): Al: 13,4-886,5; Cd: 0, 80; Cu: 24, Fe: 3, Mn: 0,4; Se: 0,81 and Zn: 20,4. O músculo do camarão investigado pode ser uma boa fonte de ferro (cerca de 88.9 mg-1g peso seco). A distribuição da concentração de Se nos tecidos apresentou muita variação entre as localidades, com níveis acima do estabelecido pela ANVISA para 67% dos musculos e 50% dos outros tecidos investigados, indicando evidências de bioacumulação do selênio. Houve correlações significativas entre os seguintes pares de elementos:: Fe-Zn (r= -0,70), Mn-Cu (r= -0,74), Se-Cu (r= -0,68), Se-Mn (r= 0,82) nos músculos, Fe-Al (r= 0,99), Mn-Al e Mn-Fe (r= 0,62), Se-Al (r = 0,88), Se-Fe (r= 0,87), Se-Mn (r= 0,58) no exoesqueleto e Cu-Zn (r = 0,68), Al-Cu (r= 0,88), Fe-Cu (r= 0,95) and Fe-Al (r= 0,97) nas vísceras.Palavras-chave: Baia de Todos os Santos, camarão, elementos traço, bioacumulação, ICP OES.
