Combining microcavity size selection with Raman microscopy for the characterization of Nanoplastics in complex matrices
|||

This study describes an extraction method and subsequent Raman analysis of pNP present in the tissues of salt-water mussels. The process combines enzymatic digestion/filtering to eliminate the biological matrix with a detection/identification procedure, which uses a micro-machined surface, composed of arrays of cavities with well-defined sub-micron depths and diameters. This sensor surface, exploits capillary forces in a drying droplet of analyte solution to drive the self-assembly of suspended nanoparticles into the cavities leaving the individual particles isolated from each other over the surface. The resulting array, when analysed using confocal Raman microscopy, permits the size selective analysis of the individual sub-micron pNP trapped in the cavities structure.

Microplastic pollution in coastal ecosystem off Mumbai coast, India

The paper strengthens the evidence that microplastics are present in the studied biota, suggesting that they are transferred between trophic levels through the interconnected food chain/web. The presence of micro plastics in fish guts highlights the need for further research on processing interventions for reducing microplastic contamination.

Personal protective equipment (PPE) pollution driven by the COVID-19 pandemic in coastal environment, Southeast Coast of India

PPE (face masks and gloves) were surveyed at six Indian beaches. There were 496 PPE counted with an average density of 1.08 × 10−3 PPE m−2. Previous studies found similar PPE density. Face masks accounted for 98.39% of all PPE recorded, while gloves accounted for only 1.61%. As a result of the increase in vaccination[…]

Effects of Marine Littering and Sustainable Measures to Reduce Marine Pollution in India

The research seeks to depict and reduce marine plastic pollution in India. A GIS map has been created to show plastic input from different river basins. In order to address the challenges of marine litter in India, a guiding model has been developed. According to the predictive model, India produces 536 thousand tons of municipal[…]

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

Plastic research, policies, waste management, socioeconomics, challenges, and opportunities are discussed. Marine plastic studies have focused on a few locations, providing information on distribution and interactions with organisms. In addition to scientific investigation, enforcement, improvisation, and, if necessary, framing new policies, integrated technologies to manage plastic waste are essential.
