Microplastic pollution threats coastal resilience and sustainability in Xiamen City, China
AI summary Read the abstract
Researchers found microplastics widely distributed in the coastal waters and marine organisms of Xiamen City, China, with fiber and fragment shapes predominating, posing threats to coastal ecosystem resilience and long-term environmental sustainability.
Microplastics have raised growing awareness due to their ubiquity and menaces to coastal resilience and sustainability. The abundance, distribution, and characteristics of microplastics in water and organisms in Xiamen were evaluated. Results showed that the average abundance of microplastics in the surface water of Xiamen Bay was 1.55 ± 1.94 items/m. The dominant color, size, shape, and polymer type were white, 1.0-2.5 mm, and fragments and lines, and polyethylene and polypropylene, respectively. The average abundance of microplastics in the fish in Xiamen was 2.44 ± 1.56 items/g wet weight. They were dominated by fibers of blue polyethersulfone and polyethylene terephthalate, and sizes <2.5 mm. There was a negative correlation between the polymer type in fish and that in water, while a positive correlation between shapes of microplastics of both fish species. Results will aid in formulating management measures for preventing microplastic pollution in Xiamen, ultimately promoting coastal resilience and sustainability of coastal communities.

Microplastics and polycyclic aromatic hydrocarbons (PAHs) in Xiamen coastal areas: Implications for anthropogenic impacts
AI summary Read the abstract
Researchers measured both microplastic abundance and polycyclic aromatic hydrocarbon (PAH) concentrations in surface water and sediments of Xiamen coastal areas in southeast China. The study found that microplastic distribution correlated with urbanization and industrial activity patterns, suggesting that anthropogenic inputs drive co-contamination of coastal environments with both microplastics and chemical pollutants.
