Raman Spectroscopy, Laser Induced Breakdown Spectroscopy (LIBS) And Principal Component Analysis (PCA) Combined For Identification Of Polystyrene Microplastics In Plastic Bottled Drinking Water
AI summary Read the abstract
Researchers combined Raman spectroscopy, laser induced breakdown spectroscopy (LIBS), and principal component analysis (PCA) to detect and identify polystyrene microplastics in commercially bottled drinking water. Spectral results were validated against standard polystyrene samples, demonstrating the potential of multi-technique spectroscopic analysis for routine microplastic identification in consumer water products.
Microplastics contamination is a growing concern. Here, Raman Spectroscopy, LIBS, and PCA were used to detect and identify polystyrene microplastics in bottled drinking water. Spectral findings were compared with standard polystyrene samples, enhancing microplastic identification.

Identification of Microplastics in Plastic Bottled Drinking Water Using Laser-Induced Breakdown Spectroscopy (LIBS) and Raman Spectroscopy
AI summary Read the abstract
Researchers tested 14 brands of bottled drinking water sold in Kenya and found microplastics in most samples, identifying five polymer types — with polyethylene and PET being most common — using laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy together. The study demonstrates that affordable spectroscopic techniques can rapidly screen bottled water for plastic contamination, and that microplastic exposure through commercial drinking water is a concern in African markets as well as wealthier nations.

Raman spectroscopy for microplastic detection in water sources: a systematic review
AI summary Read the abstract
This systematic review summarizes how Raman spectroscopy, a type of light-based analysis, is used to identify microplastics in drinking water, oceans, and wastewater. Polystyrene, polyethylene, and polypropylene were among the most commonly detected plastics across all water sources. Better detection methods like this are essential for understanding the extent of microplastic contamination in the water we drink.
Detection, Quantification, and Characterisation of Microplastics in Maltese Bottled Water
AI summary Read the abstract
Researchers detected microplastics in 84% of bottled water samples from five Maltese brands at an average concentration of 35,877 ± 23,542 particles per litre, with an average particle diameter of 2.37 μm and polymers including polyurethane, polyethylene, and polymethyl methacrylate identified by Raman spectroscopy.
The Raman Spectroscopy Approach to Different Freshwater Microplastics and Quantitative Characterization of Polyethylene Aged in the Environment
AI summary Read the abstract
Researchers used Raman spectroscopy to identify and characterize microplastics from multiple freshwater sites feeding the Baltic Sea, finding polypropylene, polyethylene, polycarbonate, and polystyrene as the most common polymer types. The study also demonstrated that Raman spectra can provide quantitative information on the crystallinity and density of aged polyethylene, enabling assessment of environmental weathering.
