“…In particular, for A. cepa, a cytotoxic effect can be observed for water samples from the rural and urban areas of the Marrecas River. These results corroborate data from Santos et al (2021), in which points P2, P4, P6, P7 and P8 also showed a cytotoxic effect for exposed amphibians.…”

“…In fact, the P7 point was the one with the highest toxicity, with CL 50% of more than 70%. These collection points have a large hydrological contribution from farming (P7: 52.67% and P8: 52.52%) and urban regions (P7: 3.87% and P8 4.10%), as indicated by Santos et al (2021).…”

“…Point P3 was the one highest escape rate (80%), which can be explained due to the river characteristics at this collection point in this season of the year. According to Santos et al (2021), the hydrological contribution area of the Marrecas river P3 point is characterized by a large area pasture (P3: 55.52% crops and 5.41% pasture), which may have generated an accumulation of organic matter and agrochemical residues use in these areas, thus justifying the toxic effect presented in this point.…”

“…The points P6, P7 and P9 still have a large contribution from crops and pastures, but also from the urban (Santos et al 2021). In particular, between points P6 and P7 of the Marrecas River there is a high discharge of urban, industrial and domestic e uents, as this the region where the Sewage Treatment Station (STS) of the Municipality of Francisco Beltrão, the municipality cemetery and the drainage of the waters of the Urutago river and the Lonqueador river, with events that may have contributed to the pollution of these waters and toxic effect presented for E. fetida.…”

“…The Marrecas River is located in the Southwest region of Paraná and is one of the main water courses in the region, with a catchment area of approximately 853km 2 , being responsible for supplying the residential, industrial and agricultural areas of the municipalities of Flor da Serra do Sul, Francisco Beltrão and Marmeleiro. Pollutant sources along the Marrecas River range from point sources (industries, domestic wastewater and sewage treatment plants) to diffuse sources (agriculture, urban and rural runoff) (Santos et al 2021), which makes water quality monitoring indispensable. Thus, the objective of the present study was to carry out biomonitoring, with bioindicators of different trophic levels of the Marrecas River waters (Francisco Beltrão, Paraná, Brazil).…”

One of the biggest environmental problems generated by anthropocentric activities is the pollution of water sources. Monitoring these areas is of great importance for maintaining their quality and for human heath, because the distribution of drinking water depends on the river ecosystem. This study aimed to realize the biomonitoring, at different trophic levels, of the Marrecas River Waters (Paraná, Brazil). The samples were collected in 2020 at nine points, three in the rural area and six in the urban area along the Marrecas River. Physicochemical and microbiological analyses, toxicity test with Artemia salina, escape test with Eisenia fetida, cytotoxicity with mammalian cells and cytotoxicity and mutagenicity test with Allium cepa were realized. The results show that the Marrecas River water quality is compromised, mainly in the urban region, possibly due to the inadequate use and occupation of its basin and inadequate disposal of effluents in the region. In addition, the study shows the importance of testing at different trophic levels, as they have different sensitivity, as is the case of A. cepa, which was the only one to demonstrate high levels of mutagenicity for the source of the Marrecas River.
