“…Fabris et al. [32] determined the volatile and semi‐volatile substances in recycled PET packages using headspace dynamic concentration as extraction method coupling with GC‐flame ionization detector (FID). The sample was ground to 20‐mesh powder in order to sufficiently release the analytes without any solvent pretreatment.…”

Excessive absorption of migrating substances from food contact materials can affect human health. Thus, it is essential to analyze the migration of contaminant from food contact materials. However, comprehensive analysis has been challenged by low concentration of migrating substances, manifold and complex matrix interference of food contact materials. Therefore, appropriate sample pretreatment methods should be applied before instrumental detection, which is essential to improve the analytical efficiency, sensitivity, and reliability. This paper systematically reviews the development of sample pretreatment methods for analysis of migrating substances from food contact materials in the past decade. To extract volatile and semi‐volatile substances, headspace extraction, headspace solid phase microextraction, and purge and trap technique are discussed. For non‐volatile substances, solid–liquid extraction and field‐assisted extraction are usually used to extract them from food contact materials, while liquid–liquid extraction, solid phase extraction, and their corresponding microextraction techniques play important roles on enrichment process. In addition, new progress in developments of sample pretreatment methods of food contact materials is summarized, covering new devices, specific adsorbents, and sample preparation methods for rapid detection. An outlook of future prospect of sample pretreatment, especially for non‐targeted analysis of non‐intentionally added substances is briefly discussed.

“…Compared to toluene, xylene is typically found in HHW in higher concentration. In addition, it is more compliant against the interaction of detergents (Fabris et al 2010 ), which can intensify MSWH and MSWS variations.…”

“…Leachate is a major negative consequence of mismanagement of MSW which could pose various risks to the environment and human health (Ferronato and Torretta 2019 ). The findings of previous studies indicate that the leachate quality can be affected by waste composition, and other factors such as moisture content, presence of adsorbents in MSW stream, landfilling method, and landfill age (Fabris et al 2010 ). Leachate, as an unpleasant and concentrated liquid, is a combination of various organic compounds, heavy metals, ammonium, total solid, and the like (Iravanian and Ravari 2020 ).…”

Household hazardous waste (HHW) includes approximately 1% of municipal solid waste (MSW), which is related to the lack of efficient separate collection schemes co-disposed with MSW in many countries worldwide. In this research, the effect of HHW diversion on leachate quality and consequent reduction in risks to the environment and human health was investigated. In this regard, physicochemical parameters of MSW leachate samples with and without hazardous fraction were characterized. Next, leachate pollution index (LPI) and associated risks were assessed. The results showed that the source separation of HHW decreases the LPI value by 13.48% and improves the potential of leachate for biological treatment, leading to a reduction in leachate treatment costs and complexity. Based on risk assessment results, HHW diversion could lower cancer risks of organic compounds and heavy metals to acceptable levels for adults and children. Moreover, by the source-separating of HHW, hazard indices for aquatic and terrestrial bioassays reduced by 41.5 and 36%, respectively. Furthermore, despite the comparatively low generated amount of HHW, this fraction should be emphasized due to its unintended effects for public health and the environment.

“…Recycled samples have been traditionally solvent extracted by Soxhlet extraction [14,15], total dissolution [5,13,[15][16][17][18][19][20], microwaveassisted extraction (MAE) [21], static headspace, supercritical fluid extraction (SFE) [22] and dynamic headspace [2,23,24] techniques. Other contaminants and additives in recycled PET have been analysed by the migration test [25] and supercritical fluid extraction [26].…”
