Additives of plastics: Entry into the environment and potential risks to human and ecological health

Journal of Environmental Management, Journal Year: 2023, Volume and Issue: 348, P. 119364 - 119364

Published: Oct. 21, 2023

A steep rise in global plastic production and significant discharge of waste are expected the near future. Plastics pose a threat to ecosystem human health through generation particulate plastics that act as carriers for other emerging contaminants, release toxic chemical additives. Since additives not covalently bound, they can freely leach into environment. Due their occurrence various environmental settings, exert ecotoxicity. However, only 25% have been characterized potential ecological concern. Despite market statistics highlighting substantial burden caused by unrestricted use additives, information on ecotoxicity remains incomplete. By focusing impacts present review aims provide detailed insights following aspects: (i) diversity environment, (ii) leaching from materials, (iii) trophic transfer, (iv) exposure, (v) risks health, (vi) legal guidelines mitigation strategies. These immense value restricting searching eco-friendly alternatives, establishing or revising agencies.

Published: May 8, 2024

The increase of micro- and nano-plastics (MNPs) in aquatic environments has become a significant concern due to their potential toxicological effects on ecosystems, food web dynamics, human health. These plastic particles emerge from range sources, such as the breakdown larger waste, consumer products, industrial outputs. This review provides detailed report transmission dangers MNPs environmental behavior, interactions within webs, emphasizing toxic impact marine life. It explores relationship between particle size toxicity, distribution different tissues, process trophic transfer through web. MNPs, once consumed, can be found various organs, including digestive system, gills, liver. Their consumption by lower level organisms facilitates progression up chain, potentially leading bioaccumulation biomagnification, thereby posing substantial risks health, reproduction, behavior species. work also how persistence bioaccumulation, pose biodiversity disrupt relationships. addresses implications for particularly contaminated seafood, highlighting direct indirect pathways which humans are exposed these pollutants. Furthermore, highlights recommendations future research directions, integration ecological, toxicological, health studies inform risk assessments develop mitigation strategies address global challenge pollution environments.
