This study aims to characterise and quantify plastic accumulation in The Great Pacific Garbage Patch (GPGP), a zone formed in subtropical waters between California and Hawaii. Surveys predicted at least 79 (45–129) thousand tonnes of ocean plastic floating in an area of 1.6 million km2. Polyethylene (PE) and polypropylene (PP) were predominantly found in this oceanic region. Results indicate 1.6 million km2 accumulation zone carrying around 42k metric tons of megaplastics, ~20k metric tons of macroplastics (e.g. crates, eel trap cones, bottles), ~10 k metric tons of mesoplastics (e.g. bottle caps, oyster spacers), and ~6.4 k metric tons of microplastics (e.g. fragments of rigid plastic objects, ropes and fishing nets).
This policy brief provides arguments on and insights into why and how plastic chemicals and polymers of concern should be integrated in the global plastics treaty. The document is an output of the Scientists’ Coalition for an Effective Plastics Treaty (SCEPT working group on chemicals, polymers and products) and aims at policymakers involved in the Intergovernmental Negotiation Committee[…]
The paper provides new insights into marine environments and human activities and suggests plastic waste should be controlled through laws that regulate waste sources and plastic additives in order to solve the problem of plastic accumulation in the oceans.
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.
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[…]
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[…]
