Marine pollution after the MV X-Press Pearl maritime disaster: Societal impacts based on research outcomes
AI summary Read the abstract
Following the 2021 MV X-Press Pearl container ship fire in Sri Lanka, researchers synthesized findings on the release of plastic pellets and microplastics into the Indian Ocean and assessed the broader social impacts, including public awareness campaigns and policy changes in plastic waste management. The disaster illustrates how a single maritime incident can contaminate vast ocean areas and catalyze regulatory change around microplastic pollution.
The occurrence and distribution of marine pollutants has been extensively investigated following the MV X-Press Pearl disaster in the Indian Ocean. Work by numerous researchers has provided the basis for determining environmental and pollution impacts in the Indian Ocean. Accordingly, this article presents social impacts based on the outcomes from recent research findings published in conventional journal articles, and refers to an ongoing research project examining plastic/microplastic pollution in Sri Lanka. The main social impacts can be summarized as: (i) knowledge transfer to the public via expert judgments, (ii) awareness in the community, and (iii) policy changes. Awareness and policy changes can gradually increase positive benefits such as improved plastic waste management, abating plastic usage, plastic recycling, and revising existing regulations where relevant.

Formation of secondary microplastics during degradation of plastics originating from the MV X-Press Pearl maritime disaster
AI summary Read the abstract
Researchers studied beach sediment along Sri Lanka's coast after the 2021 MV X-Press Pearl container ship fire and found that roughly 1,680 tonnes of plastic pellets rapidly degraded into secondary microplastics within 6–8 days due to intense heat and chemical exposure. These lightweight plastic fragments — mainly polyethylene types — are now dispersing across the Indian Ocean, highlighting how maritime disasters can rapidly escalate microplastic pollution on a global scale.
Maritime disasters and pollution: X-Press Pearl maritime debacle.
AI summary Read the abstract
This paper reviews the marine pollution consequences of the X-Press Pearl shipping disaster, which released thousands of tons of plastic pellets and chemicals into Sri Lankan waters in 2021. The incident highlights how maritime accidents can cause sudden, large-scale microplastic contamination events and underscores the need for better prevention, response, and international coordination.
Unprecedented marine microplastic contamination from the X-Press Pearl container vessel disaster
AI summary Read the abstract
Coastal pollution was assessed following the MV X-Press Pearl container ship disaster off Sri Lanka, which was described as the worst maritime accident involving chemicals and plastics and released massive quantities of plastic nurdles onto beaches. Field sampling documented extensive nurdle contamination and associated toxic element accumulation along the coastline.
Cross-Shore Microplastic Accumulation on Sri Lanka’s West Coast One Year After the Catastrophic X-Press Pearl Pollution Event
AI summary Read the abstract
Researchers conducted a detailed survey of microplastic pellet contamination along Sri Lanka's west coast one year after the catastrophic X-Press Pearl container ship disaster, which released an estimated 50 billion plastic pellets. They found that pellets were still widely present in beach sediments, with some locations showing very high densities. The study demonstrates that a single marine pollution event can result in persistent, long-term microplastic contamination of coastal environments.
Plastics, Nurdles, and Pyrogenic Microplastics in the Coastal Marine Environment
AI summary Read the abstract
Researchers examined plastic nurdle pollution and pyrogenic microplastics in coastal marine environments, with a focus on the MV X-Press Pearl cargo ship fire in Sri Lanka — the largest plastic-based maritime disaster from a single vessel in history, involving nearly 12,000 metric tonnes of plastic materials. The study documented the types and distribution of floating debris, nurdles, and fire-altered pyrogenic microplastics generated by the shipwreck along Sri Lankan coastlines.
