Abstract The accumulation of non‐biodegradable plastic waste in land and aquatic environments is expanding every day. According to data collected from various scientific reports, about 100–250 megatonnes arrives the oceans annually. Central Control Board India (2019–2020), produces 3.5 million metric tonnes annually, while only 5–10% produced recycled. non‐recycled dumped into environment either goes landfills or directly sea, which disrupts marine life ocean. We are highly dependent on at household industrial scales. Removal lowering use hazardous plastics main challenges. Researchers industrialists have come up with many ideas lower generation found that reusability easier than degradability, bioplastics ultimate solution tackle problem. Hence, developing eco‐friendly alternative without compromising physicochemical mechanical properties need hour. An conventional petrochemical bioplastics, environmentally safe, reduce our dependency fossil reserves. Therefore, this review focuses as an efficient plastics. Among renewable sustainable feedstocks available, vegetable oils most suitable resource for bioplastic production because their renewability economical nature. study concluded polyurethane‐based polymers inherently more other © 2023 Society Industrial Chemistry.

Identification and quantification of tire wear particles by employing different cross-validation techniques: FTIR-ATR Micro-FTIR, Pyr-GC/MS, and SEM

Environmental Pollution, Год журнала: 2023, Номер 326, С. 121511 - 121511

Опубликована: Март 24, 2023

Tire wear particles (TWPs) are one of the environment's most important emission sources microplastics. In this work, chemical identification these was carried out in highway stormwater runoff through cross-validation techniques for first time. Optimization a pre-treatment method (i.e., extraction and purification) provided to extract TWPs, avoiding their degradation denaturation, prevent getting low recognizable consequently underestimates quantification. Specific markers were used TWPs comparing real samples reference materials via FTIR-ATR, Micro-FTIR, Pyrolysis-gas-chromatography-mass spectrometry (Pyr-GC/MS). Quantification Micro-FTIR (microscopic counting); abundance ranged from 220,371 ± 651 TWPs/L 358,915 831 TWPs/L, while higher mass 39,6 9 mg lowest 31,0 8 TWPs/L. Most analyzed less than 100 μm size. The sizes also confirmed using scanning electron microscope (SEM), including presence potential nano samples.

The environmental contamination and biological impacts of tire particles their associated chemicals is great concern. Variously termed as wear (TWP), road (TRWP), end-of-life tires (ELTs) to differentiate between possible compositions sources in the environment, these rubber are a major source plastic pollution. array added that leach into environment presents an additional environmental, toxicological regulatory challenge. In this review, we define several topic areas relevant study particles, outlining current state ongoing challenges. Emissions estimates needed establish loads based on dated, summarised dataset rather than measured data, but determining presence hampered by lack standardised sampling methods. Several techniques for analysis available, variability model composition makes selection analytical markers challenging, does commercial standards. Toxicologically, there remains need delineate particle leachate effects and, addition, investigate emerging concern transformation products. Such knowledge required feed processes which currently regulate constituents separately whole tire. Technological solutions capture or replace progressing, often outside academia, it important scientific community collaborate with those attempting reduce impact tires, including industry.

As one of the largest sources microplastic particle emissions, tire-road wear mixtures (TRWPs) pose a potentially high threat to various environmental compartments. Their heterogenous properties, from varying size, density, shape, texture, elemental and chemical composition, cause challenging analytical workflows. Current methods for TRWP can be summarized in two main groups: single-particle-based bulk-based methods. Both groups include large variation methods, with different demands sampling sample pre-treatment, possible outputs. This review provides an overview current used studies particularly quantifications, focus on that have been peer-reviewed tested samples.
