Microplastics (MPs) (< 5 mm) are a growing environmental problem and have garnered significant global interest by scientists policy makers. Coastal ecosystems vulnerable to MP pollution, assessing their sources, fate, transport in the environment is imperative for marine ecosystem health. Data sediment still limited, particularly Pearl River Estuary (PRE) China. Here, we assessed abundance, characteristics, risks of MPs sediments from PRE. abundance ranged 2.05 × 103 items ·kg-1 7.75 (dry weight), white black were dominant colors. The majority (> 64.12%) detected <0.85mm primarily consisted pellets (36.84%) fragments (29.65%). Three polymer types identified Fourier Transform Infrared Spectroscopy (FT-IR) including polyethylene (PE), terephthalate (PET), polypropylene (PP). Meanwhile, polyurethane (PU) sponge was reported first time this study area. Observations surface morphology typical using Scanning Electron Microscopy (SEM) showed that all exhibited varying degrees erosion, characterized cracks, folds, bumpy structures. Furthermore, different concentrations heavy metal elements found on surfaces some MPs, potentially adsorbed surrounding environment. Based type quantity polymers identified, classified risk contamination PRE as category III, indicating severe contamination. Results investigation may serve an effective model other estuaries facing similar pollution regimes provides valuable information assessment.

Overtourism strains Alibaug's coastal habitats. Weekend congestion overflows local trash collection, polluting plastic and marine debris. Illegal development unregulated water sports destroy the ecosystem. Urbanization, tar ball contamination, oil spills damage these vulnerable ecosystems. These challenges are addressed by this pilot research of six institutional stakeholders, including government officials activists. Stakeholder concerns included unmanaged garbage, disaster management, safety. threatens sustainability despite BEAG clean-ups. Regenerative tourism encourages environmental protection, community-led mangrove restoration, waste management. Sustainable strategies balance restoration economic rewards. The findings demonstrate need for a comprehensive response to overtourism in Alibaug provide model other Indian communities.

Abstract Microplastics (MPs) are ubiquitous in the marine environment and harmful for biodiversity. This review was based on 311 studies published various online platforms between 2006 2024 MP contamination sediment water different countries of Asia. The research highlights an increasing trend studies, with China India. Analytical techniques sample collection, digestion, flotation, polymer identification discussed. Fourier transform infrared spectroscopy (FTIR) emerged as preferred method identification. maximum sediments recorded at Taiwan Indonesia, while China, Malaysia, fiber most dominant shape. 1–2 mm 500 μ—1 mm‐sized MPs having blue color were found dominantly. pollution indices revealed a very high risk all Asian countries. Practitioner Points India leading publications studies. Common tools used steel scoop/spatula/shovel sediment, nets water. FTIR is Highest Indonesia Dominant shape: fiber; size μ–1 mm, color.

The extensive use of the parabens triclosan (TCS) and bisphenol A (BPA) has potential adverse effects on human health aquatic organisms. However, their monitoring information in freshwater lakes is still limited. This study simultaneously summarized concentrations, spatial distribution characteristics, correlations four types parabens, TCS, BPA surface water sediment Baiyang Lake. Finally, risks target pollutants were evaluated from two aspects: ecological risks. average contaminations compounds sediment—BPA, ∑4 parabens—was 33.1, 26.1, 0.7 ng/L 24.5, 32.5, 2.5 ng/g, respectively. total concentration at inlet upstream Fu River Baigouyin significantly higher than that near Hunan outlet. In addition, Spearman’s correlation analysis showed a significant positive between compounds. hazards all within safe limits. risk quotient results indicate some locations water, TCS poses high to algae moderate invertebrates fish, appropriate attention should be paid these areas.
