Knowra Plastic pollution Plastic pollution Plastic pollution is the accumulation and release of plastic materials in the environment. Persistent debris can harm organisms and ecosystems through entanglement, ingestion, and chemical exposure.
Plastic degradation : The physical, chemical, or biological breakdown of plastic materials into smaller molecules or fragments. Sunlight, heat, and abrasion weather debris without necessarily removing it from the environment.
Plastic production : The manufacture of polymer materials and plastic products from chemical feedstocks. Production supplies the materials that can become pollution when products are discarded or lost.
Extended producer responsibility : A policy approach that makes producers responsible for managing products and packaging after use. It can shift collection and disposal costs toward businesses placing plastic products on the market.
Ghost fishing : The continued capture of aquatic animals by lost or abandoned fishing gear. Derelict plastic gear can keep killing wildlife long after it is lost.
Nanoplastics : Extremely small plastic particles, often defined as smaller than one micrometer, though definitions vary. Their measurement and environmental behavior remain difficult to establish consistently.
Microplastics : Plastic particles smaller than five millimeters, including fragments, fibers, and manufactured particles. Fragmentation turns larger litter into particles that spread widely and enter food webs.
Plastic packaging : Plastic materials used to contain, protect, or transport goods. Short-lived packaging is a major source of discarded plastic in many waste streams.
Deposit-return system : A collection scheme that refunds a deposit when consumers return a product container. Deposits can increase return rates for beverage containers and keep them out of litter.
Marine debris : Human-made solid material discarded, disposed of, or abandoned in marine and coastal environments. Plastic pollution is a major component of the broader problem of marine debris.
Plastic toxicity : The capacity of plastic particles or their chemical constituents to cause harmful biological effects. Risk depends on particle properties, additives, exposure, and organism, leaving major questions about real-world impacts.
