In this thesis, the concentrations of Chromium, Aluminum, and Iron in the rice cultivation in the district of Marona were determined. The objective was to determine the impact generated by heavy metals (Cr, Al, Fe) in rice cultivation due to the use of water from the gutter. In a plot of land with three test ponds, 1 L of water was extracted for laboratory analysis. The method used for the determination of Chromium, Aluminum, and Iron was Atomic Absorption Spectrophotometry. In the sampling, the most congested pools with high water and soil contamination load were selected, which is related to the highest pedestrian and vehicular affluence, in turn the samples were collected in three periods. An average of Chromium of 0,5 ppm was obtained, Aluminum an average of 4,66 ppm and Iron 6,26 ppm. It is concluded that the concentrations of Aluminum do not exceed the LMP, and according to the WHO, FAO and Codex Alimentarius that is 5 ppm, but in the case of Chromo and Iron the limits exceed the maximum values allowed in rice, which according to WHO, FAO and Codex Alimentarius which is for chromium 0,1 ppm and for iron 5 ppm, it is also concluded that the concentrations of chromium, aluminum and iron increase the longer the time of exposures to the environment.
