The present study was carried out in the district of Poroto, La Libertad region with the objective of determining the sustainability of pineapple cultivation and characterizing the soils considering the presence of heavy elements. Poroto, district of the province of Trujillo has an area of 276.01 km2; and a population of 3 413 inhabitants, approximatly. For the study, 16 localities were considered, and a survey was carried out with pineapple producers that includes socio-cultural, economic and environmental aspects to determine the sustainability of pineapple cultivation using the indicator method. Soil, irrigation water and pineapple fruit samples were taken to determine the concentration levels of heavy elements (Pb, Cd and Cr). The results indicate that the concentrations of Cd and Cr exceed the permissible limits of the Environmental Quality Standards in all sampled soils, the highest levels of Pb and Cd in soil are associated with the localities of Poroto, Con Con 1 and Con Con 2, more fertile soils; and higher levels of Cr and lower levels of Cd are associated with the more arid areas of Guayabito, Campo Piura, Canseco and Mochalito. In irrigation water and fruit pulp, concentrations of Pb and Cd exceed maximum environmental quality parameters. High levels of Cr in irrigation water are associated with the towns of Mochalito and Samne. High levels in Cr and Pb in fruit pulp are associated with the localities of Plazapampa and Mishirihuanca. There is soil contamination due to the high and constant contribution of Cd by irrigation water. Pineapple cultivation is sustainable, in economic, socio-cultural and environmental dimensions, due to access and facilities to the market.
