plastissisäisiä

Plastissisäisiä refers to the presence of plastic particles within the digestive tracts of organisms. This phenomenon is a significant concern within the field of environmental science, particularly in relation to marine and freshwater ecosystems. These plastic fragments can range in size from macroscopic pieces down to microscopic or even nanoscopic particles, commonly known as microplastics and nanoplastics.

Organisms ingest plastissisäisiä through various pathways. In aquatic environments, this often occurs when animals mistake plastic debris for food, such as jellyfish or plankton. The ingestion can happen at all trophic levels, from zooplankton consuming microplastics to larger fish and marine mammals ingesting larger plastic items or smaller prey that have already ingested plastic.

The consequences of plastissisäisiä are multifaceted. Physical effects can include blockages in the digestive system, a false sense of fullness leading to starvation, and internal injuries. Furthermore, plastics can leach harmful chemical additives into the organism's tissues, and they can also adsorb persistent organic pollutants from the surrounding environment, concentrating these toxins and transferring them up the food chain. The long-term ecological and health impacts of widespread plastissisäisiä are still under intensive research.
