The aim of this study is to develop a new methodology based on optical sensors able recognize and characterize microplastics collected in the marine environment. In recent years, pollution represents an environmental emergency with serious effects human health organisms. was carried out different geographical areas. Through hyperspectral imaging (HSI) approach, performed SWIR range (1000-2500 nm), classification model chemometric techniques implemented order identify rapid, non invasive non-destructive way polymers investigated samples.
