The effect of oral application of polystyrene microparticles on rainbow trout’s (Oncorhynchus mykiss) health parameters

Popis výsledku v původním jazyce

Plastic pollution is a global problem caused by an excessive use of this material, its high resistance in the environment and poor waste management. In the environment, larger-sized plastic particles may be transformed into smaller particles, so-called microplastics (< 5 mm), which have been discovered in the bodies of various organisms, across all trophic levels of the aquatic environment. The oral intake of plastic pollutants may cause mechanical damage of digestive tract; moreover, smaller particles are able to permeate the intestinal wall and transport to other tissues and organs. The results of our experiment showed that PS microparticles may negatively affect the immune system of the rainbow trout. The increased expression of the pro-inflammatory cytokines, il1β, il8 and tnfα, may cause some severe chronic diseases and could lead to changes in leukocyte migration ability, altered neutrophil activation and phagocytosis. Increase in thrα expression could negatively affect cell proliferation and differentiation. As the liver and gills are main detoxifying, metabolic and osmotic organs, their prolonged weakening can cause severe homeostatic and immunity changes with consequent susceptibility to infectious diseases and increased fish mortality.
