BELTRAN ORBEGOSO, Raúl Antonio  e  GONZA CARNERO, Katty Aracely. Cytotoxicity and genotoxicity of the waters of the Jequetepeque and Moche rivers in the environmental bioindicator Vicia faba L. Scientia Agropecuaria [online]. 2017, vol.8, n.3, pp.203-213. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2017.03.03.

Evaluation of the toxicity of the waters of the rivers as method complementary to the analysis of physical, chemical and biological provides a comprehensive water quality information, therefore, the objective of the study was to determine the levels of cytotoxicity and genotoxicity of water of watersheds high, medium and low of the Moche and rivers Jequetepeque, using environmental bioindicator Vicia faba L. "bean" (2n = 12). It germinated seeds of V. faba L.; then emerging rootlets are exposed, three hours, seven treatments: T1 (100 ml of distilled water, T2 (1 ml water from Jequetepeque river / 99 ml of distilled water), T3 (5 ml water from Jequetepeque river / 95 ml of distilled water), T4 (Jequetepeque river water 10 ml / 90 ml of distilled water), T5 (1 ml water of Moche river / 99 ml of distilled water), T6 (5 ml water of Moche river / 95 ml of distilled water) and T7 (10 ml water of Moche river / 90 ml of water) distilled). Apices were subjected to the technique of Tjio and Levan. The water of the basin of the Moche river of the T7, presents the greatest effect cytotoxic (mitotic index of 5.4% and alterations in indices of phases) and a genotoxic effect; the waters of the Jequetepeque river not demonstrate effect cytotoxic or genotoxic of importance
