“…Hg assimilation by penaeid shrimp fed field-contaminated fish tissue was approximately 72 % (Evans et al 2000). There was, however, overlap between the range of AE-109 Cd% values (approximately 54-75 %) for field-collected shrimp after consumption of amphipods (exposed to approximately 0.025 lM dissolved Cd) and values in the present study (Seebaugh and Wallace 2009). Recent work has demonstrated that inorganic Hg and Cd assimilation can be influenced by prey type, indicating the necessity of estimating AE for elements by a species across the range of potential food organisms in the field (as well as taxonomically and ecologically related surrogate prey) in addition to testing impacts of previous exposure or other environmental parameters (Dutton and Fisher 2011).…”

“…Ingested cpm for 14 C is the sum of 14 C retained and in cumulative feces for shrimp at t = 24 h. Correlations between AE and ingested cpm were analyzed for individual pre-exposure treatments as well as treatment groups using Pearson product-moment correlation (r except where indicated otherwise). Data that did not fit a normal distribution were analyzed using Spearman rank correlation (r s ) AE-203 Hg% by field-collected shrimp fed laboratorycontaminated amphipod prey (exposed to approximately 0.005 lM dissolved Hg) was greater (approximately 61-78 %) than the maximum value observed for Hg pre-exposed shrimp (Seebaugh and Wallace 2009). Hg assimilation by penaeid shrimp fed field-contaminated fish tissue was approximately 72 % (Evans et al 2000).…”

“…Previous studies indicated that subcellular distribution can be used to describe the complex binding of metal ions in different subcellular compartments with different metal ionbinding ligands (Wang and Rainbow, 2006;Buchwalter et al, 2008;Seebaugh and Wallace, 2009;Huang et al, 2010). They pointed out that metal ions binding to target subcellular compartments could reflect the metal toxicity and detoxification.…”
