Wild shrimp have an order of magnitude higher arsenic concentrations than farmed shrimp from Brazil illustrating the need for a regulation based on inorganic arsenic

Multi-energy calibration and aerosol dilution as analytical strategies to access the in vitro bioaccessibility of essential elements and arsenic in raw and cooked shrimp by plasma-based methods

“…Similar results were recently reported for raw white shrimp from Ceara state, Brazil. 5 Regarding the cooking effect, our results agreed with previous studies, 11,44,45 in which frying and grilling methods did not influence the As content from shrimp samples.…”

“…The analyte concentration in the sample was further calculated by the extrapolation method (eqn (5)). 28 C sam ¼ bC std mV sam (5) where 'b' and 'm' are, respectively, the intercept and slope of the SAM-calibration equation.…”

“…3,4 However, this food commodity can be a potential source of inorganic contaminants for humans, such as arsenic, due to its bioaccumulation potential. 5…”

“…3,4 However, this food commodity can be a potential source of inorganic contaminants for humans, such as arsenic, due to its bioaccumulation potential. 5 Although it is an important indicator of the mineral or contaminant amount in seafood, the knowledge of the total contents is insufficient for revealing the risk-benet from the consumption, as the absorption by intestinal cells relies on the solubility into the gastrointestinal (GI) chyme. In this sense, additional experiments should be performed to estimate the bioaccessibility of essential or contaminant elements and provide more accurate results about the food's nutritional value.…”

Atomic spectrometry update: review of advances in elemental speciation

“…A comparison of wild and farm shrimp in Brazil has found that wild shrimp have As concentrations an order of magnitude higher than farmed shrimp. 41 Samples of wild ( Farfantepenaeus brasiliensis ) and farmed shrimps ( Litopenaeus vannamei ) from NE Brazil were fractionated into subsamples of carapace, muscle tissue and viscera. The whole shrimp as well as the animal tissue fractions were decomposed using MAE and the total As was determined by ICP-MS.…”
