In recent decades, microplastics (MPs) have been recognised as an emerging issue in river and ocean systems. They are particles smaller than 5 millimeters in diameter, made of conventional plastics e.g. polyethylene (PE), polypropylene (PP), polyester (PS), polyamide (PA), polyvinylchloride (PVC) or polyethylene terephthalate (PET). Plastics have been produced on large scale since the 1960s and are now ubiquitous in numerous consumer and industry sectors. They are even present in common food and beverages because of the huge amounts of plastic products used in modern life. Due to their small size and irregular shapes, MPs can enter organisms throughout the food web, including humans, via ingestion, thus posing a potential threat to human health. Microplastics can be classified as primary and secondary microplastics. Primary microplastics are polymeric particles manufactured for particular applications, such as personal care and cosmetic products, industrial pellets, clothes fibres, air blasting and medical vectors. Secondary microplastics result from the breakdown of larger plastics, for example the breakdown of in situ litter. Studies have highlighted evidence of accumulation of toxic chemicals such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDTs), organo-halogenated pesticides and nonylphenols on microplastics. Moreover, most MPs are not retained by wastewater treatment processes, ending up in the receiving waters. In this paper Fourier Transform Infrared (FTIR) spectroscopy has been evaluated for its suitability for microplastics analysis in selected environmental (water, sediment) and experimental samples prepared from common used products (synthetic textiles, cosmetics, personal care products – toothpastes, facial cleansers, shower gels, sun screens, etc.). Attenuated Total Reflectance - Fourier transform infrared (ATR-FTIR) spectroscopytechnique was employed for the identification and classification of different polymers (PE, PP, PS, PA, PVC, PET) at INPOLDE interdisciplinary research network, Dunarea de Jos University of Galati, Romania, using a Bruker Tensor 27 FTIR spectrometer coupled with a diamond ATR device. The technique has the advantage of being non-invasive and applicable directly on the filter holding the extracted particles. We evaluated several materials for compatibility with microplastic suspensions containing different polymers widely found in microplastic surveys worldwide. The experiment promises the monitoring of drinking waters and surface waters for microplastics. Further studies will be carried out by coupling FTIR spectroscopy with Raman spectroscopy.
