Coastal Lagoon's dual role as a sink and source for microplastics: A case study from India.

Coastal lagoons, acting as transitional zones, are increasingly threatened by microplastic (MP) pollution. This study investigates the spatio-seasonal distribution of MPs in Chilika Lagoon sediments to propose effective mitigation measures. MPs were extracted using density flotation and wet peroxide oxidation, followed by quantitative analysis with a stereomicroscope and qualitative analysis with micro-Fourier Transform Infrared (μ-FTIR) spectroscopy.

Occurrence, characterization, and source delineation of microplastics in the coastal waters and shelf sediments of the central east coast of India, Bay of Bengal.

The present study investigates the abundance, distribution, and characterization (shape, size, colour, chemical composition) of microplastics (MPs) in surface water and sediment from the shelf region of the central east coast of India. The surface water and sediment samples were collected at varying depths (12.8-63 m) from 21 locations covering ∼1200 km.

Litter and plastic monitoring in the Indian marine environment: A review of current research, policies, waste management, and a roadmap for multidisciplinary action.

Environmental contamination due to plastic waste mismanagement is a growing global concern. Plastic problem is of particular concern to the Indian Ocean nations as Asia currently contributes to the highest share of mismanaged plastic waste. Consequently, there is a worldwide interest to understand the distribution and transboundary movement of plastic from this region, which is crucial for implementing management measures.

Assessment of litter in the remote beaches of Lakshadweep Islands, Arabian Sea.

The objective of this study was to obtain baseline data on litter from three beaches of the Lakshadweep Islands (Kadmat, Suheli Par, and Minicoy). At each site, three transects of 20 × 20 m of the foreshore and intertidal zone were sampled during low tide. All macro litter (size >2.

Comparing benthic biogeochemistry at a sandy and a muddy site in the Celtic Sea using a model and observations.

Results from a 1D setup of the European Regional Seas Ecosystem Model (ERSEM) biogeochemical model were compared with new observations collected under the UK Shelf Seas Biogeochemistry (SSB) programme to assess model performance and clarify elements of shelf-sea benthic biogeochemistry and carbon cycling. Observations from two contrasting sites (muddy and sandy) in the Celtic Sea in otherwise comparable hydrographic conditions were considered, with the focus on the benthic system. A standard model parameterisation with site-specific light and nutrient adjustments was used, along with modifications to the within-seabed diffusivity to accommodate the modelling of permeable (sandy) sediments.
