Abstract

The experimental research seeks to determine the incidence generated by heavy metal contamination that affects vegetables such as Radish, Spinach, and Lettuce in the Community of Totora located in the department of Ayacucho in Peru. The methodology used was the elaboration of the plot matrix, in a set of complete random blocks, in a 2Fx3E factorial matrix, watered by the wastewater effluents and the water supply from the supply pipes. The results of heavy metals such as Cd, Pb, and Cr were found in the vegetables that were sprayed with sewage; the concentration of Cd in the Spinach exceeded the maximum permissible limits MPL; in Lettuce, it was slightly below; with Radish, found below. Likewise, with the use of wastewater in Lettuce, Spinach, and Radishes, the absorption of Cr exceeded the limit. In the case of the vegetables under study irrigated with water of normal use, the absorption of Pb exceeded the limits.
