**Abstract**

The purpose of this research was to evaluate the environmental pollution originated by the excessive use of agrochemicals in the production of granadilla *(Passiflora ligularis)* in the Oxapampa district, Pasco – Peru. The crops of this fruit were chosen in the sectors named: Abra (Ab), Chacos (Ch), Quillazú (Qll), Acuzazú (Ac), Cañera (Ca), San Alberto (SA), Alto Río Pisco (ARP), and Paradise (Pa), where applying the nonexperimental and comparative design, the soil, water, and fruit samples were taken, which were analyzed in the specialized laboratory of the Faculty of Chemistry and Chemical Engineering, of the Universidad Nacional Mayor de San Marcos (UNMSM). A survey was also carried out by the farmers to form groups (ABC), and the results obtained were statistically analyzed by means of the comparative difference of concentration of heavy metals in three groups selected according to intensity of use of agrochemicals, which were between 0.26 and 0.36 mg of Cu/kg of fruit, between 0.001 and 0.003 mg of Cd and Pb/kg of fruit, between 0.0012 and 0.0006 mg As and Hg/kg of fruit, between 19 and 25 mg of Cu/kg of soil, between 0.02 and 0.08 mg of Cd and Pb/kg of soil, between 0.05 and 0.08 mg of As and Hg/kg of soil; between 1 and 1.12 mg of Cu/l of water, between 0.002 and 0.003 mg of Cd and Pb/l of water, between 0.002 and 0.005 mg of As and Hg/l of water; being observed high averages in some heavy metals and whose comparisons were not significant for As, Hg, Pb, Cd, Cu in fruits, soil, and water, and significant only the Cd in fruits and Hg in soils, concluding that there is a potential risk of toxicity due to ingestion of granadilla (*P. ligularis*)*.*
