Furthermore, we compared environmental particles to weathered artificial MPs under controlled light and temperature conditions and to unaltered pristine materials to assess the results. In this context, the principal aim of our research has been to qualitatively evaluate the natural weathering of environmental MPs collected in an Italian freshwater body (the Ofanto River) using ATR-FTIR technology. However, it could also be used to evaluate the degree of ageing of MPs collected from the environment. It has recently gained popularity in microplastic (MP) pollution research to determine the chemical composition of unknown plastic fragments. Fourier transform infrared (FTIR) is a spectroscopy technique widely used to identify organic materials. ![]()
