“…Because of the complexity of these matrices, efficient extraction and clean-up protocols are also needed. For analyte extraction, approaches based on Soxhlet extraction, solid-liquid extraction, pressurized solvent extraction (PSE) (Choi et al, 2016;Chung and Chen, 2011), or microwave assisted extraction (MAE) have been used (Chung and Chen, 2011;LeDoux, 2011). Solid phase extraction (SPE) has usually been the method of choice for clean-up of the extracts (Chung and Chen, 2011;LeDoux, 2011;Santhi et al, 2012).…”

Pesticide pollution in water has been well described; however, little is known on pesticide accumulation by aquatic organisms, and to date, most studies in this line have been focused on persistent organochlorine pesticides. For this reason, a method based on QuEChERS extraction and subsequent liquid chromatography-tandem mass spectrometry (LC-MS/MS) has been developed and validated for the determination of 52 medium to highly polar pesticides in fresh fish muscle. Target pesticides were selected on the basis of use and occurrence in surface waters. Quantification is carried out following an isotope dilution approach. The method developed is satisfactory in terms of accuracy (relative recovery between 71-120%), precision (relative standard deviation below 20.6%) and sensitivity (limits of determination in the pg/g or low ng/g f.w. range for most compounds). The application of the validated methodology to fish specimens collected from the Adige River (Italy) revealed the presence of trace levels of diazinon, dichlorvos and diuron, and measurable levels of metolachlor, quinoxyfen, irgarol, terbutryn, and acetamiprid, but in all cases at concentrations below the default maximum residue level of 10 ng/g established for pesticides not specifically regulated in fish. Metolachlor and quinoxyfen were both the most ubiquitous and abundant pesticides, in agreement with their high potential of bioaccumulation. Both are toxic to aquatic organisms, and therefore, their potential effects on aquatic ecosystems should be further explored.

“…S2, the extraction efficiency of acetonitrile and ethyl acetate was better than dichloromethane for all the analytes except amitrole (a strong polar compound). Dichloromethane, a weak polar solvent, showed only 11–40% extraction efficiency, which was not acceptable, as has been used for extraction of organochlorine pesticides in fish samples previously . Compared to ethyl acetate, acetonitrile was stronger polar solvent, which could extract more polar compounds, leading to more matrix interferences and ion suppression for the polar target analytes, especially amitrole .…”

We describe a new methodology for the simultaneous determination of the endocrine-disrupting herbicides (acetochlor, alachlor, amitrole, and atrazine), fungicides (carbendazim, triadimefon, penconazole, and propiconazole), and insecticides (carbaryl and carbofuran) in fish samples followed by high-performance liquid chromatography with tandem mass spectrometry. Samples were extracted and purified using the pass-through cleanup approach. The recoveries of the pesticides were in the range 71.8-116.5%, with relative standard deviations lower than 15.28%. Limits of quantitation were in the range of 0.03-2.50 μg/kg. Validation results on linearity, accuracy, and precision, as well as on application to the analysis of the endocrine-disrupting pesticides in 20 fish samples, demonstrated the applicability to screen the presence of pesticides in fish.

“…However, these chemicals are hard to degrade, and hence capable of remaining in the environment for decades [10]. OCPs are chemical persistent, lipophilic, and hydrophobic compounds that can accumulate in biota, become biomagnified through the food chain, meaning that the concentrations in biota increase as the trophic level increases [11,12]. In aquatic environments, hydrophobic compounds such as OCPs can enter shrimps, mainly via two pathways: bioconcentration, directly through the water environment and/or biomagnification, through food web preys.…”

Shrimps are widely distributed in coastal areas, estuaries and rivers. Although this shellfish is a good source of nutrients, it can also accumulate environmental contaminants, such as organochlorine pesticides (OCPs), brominated flame retardants (BFRs), synthetic musks (SMs) and polycyclic aromatic hydrocarbons (PAHs). Due to their bioaccumulative properties, these pollutants are endocrine disruptors. In this review, an overview of the world's shrimp market, pollutants legislation and values found in shrimp samples will be discussed. Shrimps analysed from all continents showed the presence of contaminants, Asia being the continent with the highest values reported. The concentration values reached a maximum of 26100 ng/g wet weight (ww) for OCPs, of 226.45 ng/g ww for BFRs, of 12.1 ng/g ww for SMs and of 50650 ng/g ww for PAHs. Exposure data and risk, taken from different studies, are very variable and indicate that shrimp's consumption may represent a risk especially in certain geographic areas.
