Microplastic concentrations in urban coastal waters are regarded as critical in terms of particle toxicity. A plastic material can retain hydrophobic additives and concentrate persistent organic pollutants (POPs) in marine environments. The paper highlights literature that shows microplastics increase indirect exposure to endocrine disrupting additives to humans through fragmentation of plastics, their ingestion by marine organisms, their leaching into digestive fluids, and their subsequent bioaccumulation and transfer to humans. Humans’ endocrine and immune systems can be disrupted by the additives. As a precautionary measure, we should reduce the use and consumption of plastics in our society. A reduction in plastic consumption is also recommended from the viewpoint of reducing global warming impacts, maximizing resource efficiency, and practicing sound waste management.
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[…]
