Complex and organic-rich solid substrates such as sludge and soil have been shown to be contaminated by microplastics; however, methods for extracting plastic particles have not yet been systemically tested or standardized. This study investigated four main protocols for the removal of organic material during analysis of microplastics from complex solid matrices: oxidation using HO, Fenton's reagent, and alkaline digestion with NaOH and KOH. Eight common polymer types were used to assess the influence of reagent exposure on particle integrity. Organic matter removal efficiencies were established for test sludge and soil samples. Fenton's reagent was identified as the optimum protocol. All other methods showed signs of particle degradation or resulted in an insufficient reduction in organic matter content. A further validation procedure revealed high microplastic extraction efficiencies for particles with different morphologies. This confirmed the suitability of Fenton's reagent for use in conjunction with density separation for extracting microplastics. This approach affords greater comparability with existing studies that utilize a density-based technique. Recommendations for further method optimization were also identified to improve the recovery of microplastic from complex, organic-rich environmental samples.

“…A potential alternative to peroxide oxidation is the use of Fenton's reagent. This has previously been 94 used to extract microplastics from organic-rich wastewater samples 34 . Fenton's reagent is an advanced 95 oxidation process using H 2 O 2 in the presence of a catalyst (Fe 2+ ).…”

“…Therefore, PLA microplastics can be released from wastewater treatment plants. Tagg et al (2017) used Fenton's reagent to isolate microplastics from organic-rich wastewater. Authors found that the catalytic reaction did not affect microplastic chemistry or size, enabling its use as a pre-treatment method for focal plane array-based micro-FT-IR imaging used for detection of microplastics.…”

This annual review covers the literature published in 2017 on topics related to the occurrence and fate of emerging environmental pollutants in wastewater. Due to the vast amount of literature published on this topic, we have discussed only a portion of the quality research publications, due to the limitation of space. The abstract search was carried out using Web of Science, and the abstracts were selected based on their relevance. In few cases, full-text articles were referred to better understand new findings. This review is divided into the following sections: antibioticresistant bacteria (ARBs) and antibiotic-resistant genes (ARGs), disinfection by-products (DBPs), estrogens, pesticides, pharmaceuticals and personal care products (PPCPs), and microplastics, a new section added this year.

“…In brief, the modified NOAA method (Zobkov and Esiukova ) consists of the following main steps (Fig. , lower frame): Multiple MPs extraction from a sediment sample by means of density separation with ZnCl 2 solution (specific density 1.6 g mL −1 ). Filtering of supernatant and solution above the sediment with the filter funnel. Wet peroxide oxidation on the water bath with the Fenton's reagent (Tagg et al ). Calcite fraction digestion with HCl solution. Filtering with filter funnel. Density separation to detach oxidized organic matter. Filtering with filter funnel. MPs detection with stereomicroscope. …”

The Munich Plastic Sediment Separator (MPSS), proposed by Imhof et al. (), showed its high efficiency in extracting microplastics (MPs) from natural sediment samples preliminarily cleaned and then enriched by MPs in laboratory. We tested the efficiency of the MPSS, assembled at the Atlantic Branch of P.P.Shirshov Institute of Oceanology (Kaliningrad), using unprepared natural bottom deposits of different types collected in the Baltic Sea. The tests that were performed included spikes of sediments with artificial reference particles (ARPs) and the sediment samples analyses with two separate methods of extraction and determination of MPs content in residuals of MPSS. While the ARP extraction efficiency from natural sediments by the MPSS was really high (97.1% ± 2.6%; p = 0.05; n = 14; confidence interval, t‐distribution), the extraction efficiency of marine MPs was considerably lower (13–39%) than that obtained with a modification of the method previously published by NOAA. The remaining marine MPs were found in the spoil dump and in the bulk solution fractions of the separator, indicating that MPs were not perfectly cleaned from sediment particles, probably, due to presence of organic matter. It is concluded that the MPSS application for quantitative MPs analysis requires further testing and elaboration of standardized extraction procedures.
