The Ivinhema River Basin is affected by the expansion of sugarcane cultivation areas, which impacts the water quality of
its streams. The aim of this study was to evaluate the cytotoxic, genotoxic, and mutagenic potential of water samples from
three streams of the Ivinhema River Basin using the Allium cepa test. Sampling was conducted in March 2017. Surface
water samples collected from the Piravevê, Vitória, and Rosário streams induced cytotoxic and genotoxic effects in A. cepa.
Reductions in both germination and cell division were observed, which may have been related to the flow of toxic residues
from the sugarcane monoculture into the stream’s waters. Therefore, there is an urgent need to develop restoration projects
aimed at conserving the water quality and biodiversity in these aquatic environments.
