Summary

This Brazilian study combined biomonitoring of fish bioindicators with environmental education activities in the Iguaçu River basin in Paraná, to assess water toxicity and build community awareness. Fish collected from 10 sites showed toxicity biomarkers consistent with contamination including microplastics, and the findings were used to design targeted environmental education programs in local schools.

Study Type Environmental

Knowledge about the consequences of microplastics and other emerging contaminants in natural environments is still largely unexplored. Therefore, this study aims to analyze the toxicity of the water in the Iguaçu River basin using two species of bioindicator fish and, based on these results, initiate a schedule of environmental education actions in Paraná. To this end, fish were collected at 10 different points along the river, including urban and rural areas and areas with greater extent of riparian forest, one of which was the Iguaçu National Park. A schedule of environmental education activities was also initiated in five schools in southwestern Paraná, using active methodologies.
