“…No information was found concerning microelements in L. reynaudii. The detected micronutri-ent concentrations in the studied species reflect the influence of each species (feeding preference, trophic level, behavior, size, and seasonal changes in physiology) (Gomes et al, 2013;Maioli et al, 2010), but also the environmental inputs showing the variability of metal concentrations originated from different sources present in Oceans. In terms of risk assessment, cephalopods can be useful since they accumulate high levels of essential and non-essential elements (Semedo et al, 2012).…”

The most consumed squid species worldwide were characterized regarding their concentrations of min-erals, fatty acids, cholesterol and vitamin E. Interspecific comparisons were assessed among species and geographical origin. The health benefits derived from squid consumption were assessed based on daily minerals intake and on nutritional lipid quality indexes. Squids contribute significantly to daily intake of several macro (Na, K, Mg and P) and micronutrients (Cu, Zn and Ni). Despite their low fat concentration, they are rich in long-chain omega-3 fatty acids, particularly docosahexaenoic (DHA) and eicosapentanoic (EPA) acids, with highly favorable x-3/x-6 ratios (from 5.7 to 17.7), reducing the significance of their high cholesterol concentration (140-549 mg/100 g ww). Assessment of potential health risks based on minerals intake, non-carcinogenic and carcinogenic risks indicated that Loligo gahi (from Atlantic Ocean), Loligo opalescens (from Pacific Ocean) and Loligo duvaucelii (from Indic Ocean) should be eaten with moderation due to the high concentrations of Cu and/or Cd. Canonical discriminant analysis identified the major fatty acids (C14:0, C18:0, C18:1, C18:3x-3, C20:4x-6 and C22:5x-6), P, K, Cu and vitamin E as chemical discriminators for the selected species. These elements and compounds exhibited the potential to prove authenticity of the commercially relevant squid species.

“…When considering MAE, due to the principle of microwave heating, the choice of the solvent depends also on its ability to absorb microwaves, defined by its dielectric constant (e 0 ). Hexane-acetone mixtures, toluene, methylene chloride, benzene, cyclohexane, and dichloromethane are known to be good solvents for PAH extrac-tions and are commonly used worldwide although some are highly toxic and should be slowly being phased out from analytical meth-ods (Maioli, Rodrigues, Knoppers, & Azevedo, 2010;PortetKoltalo, Oukebdane, Dionnet, & Desbène, 2008;Selli & Cayhan, 2009;Serpe et al, 2010;Soclo et al, 2008). Apolar solvents such as hexane do not meet the requirement to can be used in MAE and despite the fact they are known to be appropriate for aromatic compounds they cannot be used alone.…”

Analysis of polycyclic aromatic hydrocarbons in fish: Optimisation and validation of microwave-assisted extraction

et al. 2012

An accurate and sensitive method for determination of 18 polycyclic aromatic hydrocarbons (PAHs) (16 PAHs considered by USEPA as priority pollutants, dibenzo [a,l]pyrene and benzo[j]fluoranthene) in fish samples was validated. Analysis was performed by microwave-assisted extraction and liquid chromatog-raphy with photodiode array and fluorescence detection. Response surface methodology was used to find the optimal extraction parameters. Validation of the overall methodology was performed by spiking assays at four levels and using SRM 2977. Quantification limits ranging from 0.15-27.16 ng/g wet weight were obtained. The established method was applied in edible tissues of three commonly consumed and commercially valuable fish species (sardine, chub mackerel and horse mackerel) originated from Atlantic Ocean. Variable levels of naphthalene (1.03-2.95 ng/g wet weight), fluorene (0.34-1.09 ng/g wet weight) and phenanthrene (0.34-3.54 ng/g wet weight) were detected in the analysed samples. None of the sam-ples contained detectable amounts of benzo[a]pyrene, the marker used for evaluating the occurrence and carcinogenic effects of PAHs in food.

“…More fast methods include sonication-assisted extraction (Dsikowitzky et al 2011;Maioli et al 2010), microwave-assisted liquid extraction (MAE) (Zuloaga et al 2009;Cortazar et al 2008) and accelerated solvent extraction or pressurized liquid extraction (ASE) usually Napthalene Fluorene Pyrene Environ Chem Lett conducted with the Dionex system (Sloan et al 2004). Finally the matrix solid-phase dispersion (MSPD) has also been applied to extract PAH from mussels even in miniaturized scale (Campins-Falco et al 2008).…”

Polycyclic aromatic hydrocarbons (PAH) are broad environmental contaminants, which, due to their lipophilic profile, tend to be absorbed on particles and finally accumulate in marine environments. Due to their cumulative power of adsorption, bivalves are major bioindicators of PAH pollution. Substantial research has been performed on the effects of PAH pollution on marine bivalves. Here we review PAH analysis using bivalves and effects of PAH on bivalves. Specific focus is given on: (1) PAH analytical methodologies and their performance, (2) levels of marine PAH as measured through bivalves within the last decade; current pollution status and (3) health effects of PAH on bivalves.
