摘要

Effects of anthropogenic activities such as urbanization, population growth, and agriculture on water quality aremajor concerns particularly in low‐income countries where water quality monitoring can be challenging. The purpose ofthe present study was to evaluate the cytogenotoxic potential of water from urban and rural Malagasy marshes, couplinga fish (Nile tilapia, Oreochromis niloticus) and a plant (Allium cepa) species as bioindicators. The fish and plants wereexposed for 72 h to water sampled in the two locations investigated. Using the comet assay on fish erythrocytes, DNAstrand breaks were assessed, while mitotic index and nucleolar alterations were estimated in cells of the plant root apex.Comet assays revealed significant DNA strand breaks to fish erythrocytes in both the marshes investigated while themitotic index and nucleolar characteristics in the roots of A. cepa mainly highlighted potential cytotoxicity in the urbanmarsh. Our results demonstrate the advantages of coupling in vivo biological test systems to screen potential cytogenotoxicityof surface water in low‐income countries where comprehensive data sets of aquatic contaminants are oftenlacking.
