What is Unprecedented marine microplastic contamination from the X-Press Pearl container vessel disaster about?

The objectives of the research was to assess the coastal pollution by plastic nurdles, pyrolitic debris, associated potential toxic elements (PTEs) concentrations and mitigatory efforts by the worst ever maritime accident of a chemical and plastic boarded container vessel; MV X-Press Pearl. Field sampling was carried out three times during May, June, and September 2021 at Sarakkuwa, Sri Lanka. Pellet pollution index (PPI) was determined to compare the degree of plastics pollution. Density separation (NaCl) followed by wet peroxide digestion for plastic separation and characterized by Fourier transform infrared spectroscopic, thermo gravimetric analysis and differential scanning calorimetric analysis. Sand and plastics samples were digested and analyzed for PTEs (Li, Mo, Cr, Pb, and Cu), are suspect to mix during disaster. Identified debris were mostly confirmed as low-density polyethylene, epoxy resins, olefin copolymers, aromatic polyamides, natural rubber, and polyethylene terephthalate. Sulfur contamination and physical erosion were observed in nurdles received in June and September. Calculated PPIs were 'high' for Sarakkuwa beach even in September with a very high pellet pollut
