“…Table summarizes recent contributions to green sample preparation methods for environmental applications. ,,,− As observed in the case of bioanalysis, the use of liquid-based or solid-based extractions is equally applied. In this case, a preference for commercial sorbents is observed, with aqueous matrices being the choice of preference.…”

“…The presence of a high organic content can degrade peak identification, potentially leading to an overestimation of MP content and compromising the reliability of the chromatogram interpretation [31]. If the amount of organic matter is too high, sample preparation may be useful and the perceived advantage of TED-GCMS will be lost [64]. In some cases, such as for PVC, the quantification or qualification of polymers using the analytical method TED-GCMS is difficult or not possible [65].…”

Microplastic (MP) has emerged as a significant environmental challenge due to increased plastic production and its widespread presence in the environment. This study aimed to assess MP concentrations throughout the treatment process at nine wastewater treatment plants (WWTPs) in Germany, from influent to effluent. A customized sampling technique was employed, followed by field and laboratory preparation and the quantification of polymers (PE, PP, PS, PMMA, and PET) using TED-GCMS. MP concentrations decreased progressively in the WWTPs, with influent concentrations ranging from 2.5 to 13.6 mg/L. Effluent concentrations in the conventional WWTPs ranged from 0.001 to 0.051 mg/L, while advanced treatment via filtration yielded concentrations below the limit of quantification at 0.005 mg/L. All tested of the WWTPs demonstrated an over 99% removal efficiency for microplastics. Despite effective retention by the WWTPs, a critical evaluation of the results is necessary. There is a need to optimize existing technologies and enhance the standardization of sampling, processing, and measurement methods, as well as intensify efforts towards creating preventive measures to reduce plastic emissions.

“…A solvent-free sample preparation method was developed by Wenzel and co-workers 49 for the analysis of microplastics in sediments. Analyte separation from the sample matrix was based on the hydrophobic adhesion of microplastic on finely dispersed upstreaming air bubbles.…”
