Polymeric Materials in the Anthropocene: Environmental Accumulation, Human Health Concerns, and Cultural Response
Abstract: Polymers made via conventional techniques are very useful because of their strength, adaptability, and cheap. Plastics are not degradable naturally, which creates lots of environmental issues. As plastic products degrade over time, they decompose into microplastics which enter the environment. These microscopic particles called microplastics have been identified in agricultural soils, freshwater and marine environments, and atmospheric dust, enabling their continuous movement through ecosystems and food webs. Recent research shows …
