“…In addition, the method allows low manipulation of the sample, reduced solvent consumption and lowered extraction and analysis time. Many authors [23][24][25]37,38] applied analogous extraction and purification methods on solid environmental matrices yielding comparable results, but this is the first time that this analytical procedure is carried out on biopolymer samples.…”

The microbial synthesis of polyhydroxyalkanoates (PHA) from organic wastes is a valuable process to valorize available renewable resources, such as food wastes and biological sludge. Bioplastics find many applications in various sectors, from medical field to food industry. However, persistent organic pollutants could be transferred from wastes to the final product. The present paper demonstrates that the use of municipal wastes in PHA production is safe for the environment and human health and provides a polychlorinated biphenyl (PCB) profile in both commercial and waste-based PHA samples. PCB analysis in several PHA samples showed very low concentrations of the target analytes. Commercial PHA samples showed a similar PCB level with respect to PHA samples from municipal waste/sludge and higher than PHA samples from fruit waste. For all analyzed PCBs, detected concentrations were consistently lower than the ones reported in regulatory framework or guidelines.

“…Lately, analytical procedures that combine extraction and clean-up steps have been developed. These methods involve reduced organic solvent consumption as well as reduced extraction and analysis time, and less sample handling while providing performance comparable to conventional sample preparation methods [23][24][25].…”

“…Low-(total average 160 pg L −1 ; n = 7) and mid-(total average 225 pg L −1 ; n = 3) range calibration curve reproducibility studies were performed. Statistically derived MDLs were determined by analyzing seven ∼1.5 g ww aliquots of a bowhead whale blubber sample spiked with analytes at concentrations corresponding to the penultimate calibration point (total average 7 pg L −1 ) [13]. MDLs were determined by multiplying the standard deviation by the one-sided student t-test static (99% confidence).…”

“…SPLE incorporating acidic silica or Florisil TM in single extraction cells may be appropriate for POPs analysis in blubber, depending on the desired blubber sample mass. Theoretically, <0.3 g of lipid (or 0.4 g of blubber assuming 75% lipid) could be extracted for PBDEs, PCBs, and OCPs using previously published Florisil TM SPLE methods in a single 100 mL extraction cell [13]. Select OCPs eliminated from this report's analyte list due to use of acidic silica may potentially be extracted if utilizing a Florisil TM SPLE method.…”

“…One solution to reduce the number of sample preparation steps for POPs analysis is selective pressurized liquid extraction (SPLE), a technique that combines pressurized liquid extraction with cleanup adsorbent/s [10][11][12][13]. By reducing the number of sample preparation steps, SPLE has the potential to reduce possibilities for analyte loss and sample contamination.…”

Chemicals are widely used in aquaculture and one of the main recipients of these analytes is the aquatic environment. The aim of this work was to develop and validate a simple and sensitive method for the determination of multiclass chemotherapeutic agents in farmed fish and shellfish using matrix solid-phase dispersion and liquid chromatography-tandem mass spectrometry. Residues of azamethiphos, three avermectins, two carbamates, and two benzoylureas were extracted from samples using silica gel as clean-up adsorbent and 0.5% acetic acid in acetonitrile as elution solvent. The extraction conditions were investigated and optimized using an experimental design. Mass spectrometry detection was carried out in positive electrospray ionization mode with multiple-reaction monitoring scan (except for benzoylurea family). Matrix-matched standards were used for the drugs quantification. Good linearity (R(2) ≥ 0.996) was observed in the range of 5-500 μg kg(-1). Limits of detection were in the range of 1.5-3.7 μg kg(-1). Recoveries from salmon samples spiked with veterinary drugs were in the range 84.9-118%. Precision was satisfactory since relative standard deviations were lower than 10.6%. The method can be successfully applied for the analysis of fish and shellfish from aquaculture.
