“…Also, estuarine mangrove provides ecological restoration for coastal animal protection, sediment trapping and decreasing impacts from marine disaster (Suk-ueng et al, 2013). To date, the global marine environment has found significant annual accumulation of more than 12.7 million tonnes of plastic pollution, with an estimated 296,000 tonnes of plastic currently existing in the oceans (Gérigny et al, 2022;Curren and Leong, 2023). Microplastics (MPs) is defined as a small plastic piece <5 mm (generally 50 to 5000 μm) in diameter from the direct consumer products, called "Primary MPs" and from the fragmentation of larger plastic objects, called "Secondary MPs" caused by the processes of degradation (Tongnunui et al, 2022).…”

Aim: The prevalence of plastic particles has become a global crisis for the environment pollution and human life. This study aimed to investigate the contamination of microplastics (MPs) in marine environments and to determine the relationships between MPs pollution and types of land use. Methodology: Two invertebrate species (Anadara granosa and Litopenaeus vannamei) and sediment samples were collected for the analysis of MPs accumulation in the Chanthaburi estuarine ecosystem. The microplastics contamination and pollution were determined with visual identification and environmental index, respectively. The abundance and the land use type of MPs in Chanthaburi Province were compared by a Geographic Information System (GIS). Results: The MPs contamination in the white shrimps were higher than the cockles. The black filamentous type of MPs was a major characteristic which ranged between 0.43–0.85 mm, 0.45–0.65 mm and 1.25 – 3.05 mm in A. granosa, L. vannamei and sediment, respectively. The MPs pollution index (PLI and BCF) showed low levels in the hazardous category. The Chanthaburi land use analysis showed variation in the land use change and a strong correlation between green areas and the MPs contamination. Interpretation: The statistical analysis suggested differences between MPs abundance in our samples.The utilization of agriculture and forest land use types could relieve the impact of MPs accumulation.This study also demonstrated the need for managing MPs pollution in Thai marine ecosystems.

Plastic pollution is considered a pervasive global environmental challenge. Colored microplastics are prevalent in aquatic environments and the gastrointestinal tracts of wild-captured fish and crustaceans. Fish are thought to employ color vision to detect microplastics, prompting our investigation into microplastic ingestion patterns in three marine fish species, Chrysiptera cyanea, Hypoatherina tsurugae, and Plotosus japonicus, and three freshwater fish species, Rhodeus ocellatus, Pseudorasbora parva, and Misgurnus anguillicaudatus. Microplastics in red, blue, yellow, green, and gray were introduced to these species, and their ingestion was observed over a 4 h period under light conditions. Additionally, as crustaceans play an important role in connecting producers (phytoplankton) and consumers (fish) in natural ecosystems, we assessed a freshwater crustacean, Neocaridina denticulata. The crustacean did not ingest microplastics, and only 14% of P. parva individuals ingested microplastics (a proportion lower than that observed in the other fish species). Notably, C. cyanea, P. japonicus, and R. ocellatus exhibited color preferences in microplastic ingestion, with C. cyanea favoring red, P. japonicus preferring blue and gray, and R. ocellatus favoring red and yellow. Conversely, H. tsurugae, P. parva, and M. anguillicaudatus did not exhibit such color preferences. These findings suggest that certain fish use color vision to recognize and selectively ingest microplastics, with color preference being species-specific. Overall, this study provides new insights into microplastic ingestion by fish, potentially informing future toxicological assessments of microplastics in marine and freshwater fish and crustaceans intendan consumption.
