A study was conducted to determine whether microplastics are found in six human placentas, collected from consenting women who had a physiological pregnancy. Twelve microplastic fragments (ranging in size from five to ten microplastics) were found in four placentas (5 on maternal side, 4 on fetal side, and 3 in chorioamniotic membranes), both morphologically and chemically characterized. The samples were all pigmented; three were polypropylene, a thermoplastic polymer, while nine were pigment-only, all of which were used in coatings, paints, adhesives, plasters, finger paints, polymers, and cosmetics.
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[…]
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.
