Abstract:
Humans ingest five grams of microplastics on a weekly basis. Beverages serve as a microplastic conduit for entering the human body. Nevertheless, beer received minimal attention on microplastics despite its popularity. The objective of this study is to measure the quantity of microplastic particles that are present in locally brewed and packed beers and the amount of microplastic consumed by the beer drinkers in Malaysia. To accomplish this, a total of 15 beer samples from 5 distinct brands were examined. The analysis indicated that microplastics fibres measuring less than 0.5mm and fragments

Microplastic pollution has become a prevalent environmental issue, with particles smaller than 5 millimeters infiltrating virtually every ecosystem. This review provides a comprehensive analysis of microplastic sources, formation mechanisms, quantification techniques, environmental impacts, toxicological effects, and remediation strategies. Microplastics originate from both primary and secondary sources. Primary microplastics include deliberately manufactured particles such as microbeads and synthetic fibers from textiles. Secondary microplastics result from the degradation of larger plastic d

Abstract Near-infrared (NIR) spectroscopy is a promising candidate for low-cost, nondestructive, and high-throughput mass quantification of microplastics in environmental samples. Widespread application of the technique is currently hampered mainly by the low sensitivity of NIR spectroscopy compared to thermoanalytical approaches commonly used for this type of analysis. This study shows how the application of NIR spectroscopy for mass quantification of microplastics can be extended to smaller analyte levels by combining it with a simple and rapid microplastic enrichment protocol.

In recent years, the problem of "microplastics" has become increasingly worrying, as the amount of plastics that will be produced in the future will increase significantly. Microplastics are defined as emerging pollutants, due to the risks they may cause to the environment and especially to human health. The analytical issue behind their quantification in environmental matrices is quite complex. The thermoanalytical Py-GC/MS technique can provide qualitative and quantitative information about the microplastics more accurate than already applied optical techniques.

Abstract:
To investigate plastic pollution in rivers, the Tara schooner collected samples from 9 of the main European rivers from May to November 2019. The objectives of the present study are the quantification of the microplastic (MP) contamination and the identification of the chemical nature of microplastics. Thus, extraction methods and automated computer processing for polymer characterization were developed. The three main polymers found were polyethylene (PE), polypropylene (PP) and polystyrene (PS). These results must be compared to the results from other rivers to draw a consistent pattern.

Plastics are an important material with widespread applications. However, their widespread use and poor end-of-life management have led to their extensive environmental pollution.
