Spatial distribution and ecological risk evaluation of microplastics in surface water, sediment, and Oreochromis niloticus from the Eravur sector, Batticaloa Lagoon, Sri Lanka

Occurrence and Characteristics of Microplastics in the Surface Water and Sediment of Lagos Lagoon, Nigeria

AI summary · Read the abstract

Researchers characterized the occurrence, abundance, and physical properties of microplastics in the surface water and sediments of Lagos Lagoon, Nigeria, identifying key polymer types and potential local sources. This study fills an important data gap for West African urban water bodies, demonstrating that rapidly developing coastal megacities face acute microplastic contamination threatening both local fisheries and public health.

A Comprehensive Review of Microplastic Contamination in Sri Lanka: Sources, Sinks, and Pathways

AI summary · Read the abstract

This review synthesized all available research on microplastic contamination in Sri Lanka since its first documented case in 2017, mapping sources, environmental sinks, and transport pathways across beaches, waterways, and marine systems. The study highlights how island nations with limited waste management infrastructure serve as both hotspots of microplastic generation and vulnerable endpoints of global ocean plastic transport.

Microplastics Contamination in Marine Organisms of Different Trophic Levels from Dikkowita Harbor

Microplastics menace: the new emerging lurking environmental issue, a review on sampling and quantification in aquatic environments

AI summary · Read the abstract

Researchers reviewed current methods for detecting and measuring microplastics in water, finding that inconsistent sampling and analysis techniques make it difficult to compare data across studies, and calling for standardized, automated methods to enable reliable monitoring of this growing contaminant.

Microplastics in Surface Water and Gastrointestinal Tracts of Demersal Fishes (Oreochromis niloticus and Cyprinus carpio) in the Largest Wetland of the Philippines

AI summary · Read the abstract

Microplastics were found in 84% of fish from the Philippines' Agusan Marsh — the country's largest wetland — with up to 3.2 MPs per gastrointestinal tract on average and 20 polymer types identified in water, dominated by rayon and polyester. The pervasive contamination of a major tropical wetland and its commercially consumed fish species signals significant risks to food web integrity and human dietary exposure through freshwater fish consumption.
