Soil, Runoff Water Contaminated with Agrochemicals, their Relationship in Fruits (Passiflora ligularis) Oxapampa-Pasco

Abstract

It was investigated in the district of Oxapampa, a place of high production of granadilla, where it was observed that farmers frequently use pesticides, they are protagonists of contaminating the soil, runoff water and that it is directly related to the quality of the fruit. The objective was to evaluate the relationship of soil and runoff water, in the concentration of heavy metals in fruits of (Passiflora ligularis), in the sectors; del Abra (Ab), Chacos (Ch), Quillazú (Qll), Acuzazú (Ac), Cañera (Ca), San Alberto (SA), Alto Río Pisco (ARP) and Paraíso (Pa). The Non-experimental and Correlative Design was used. The concentration correlation of As, Hg, Cd, Cu and Pb found in samples collected from soil and water from production fields of three groups (ABC) of farmers, as well as their relationship with the contamination of the fruits was determined. Whose results: Soil-Fruit: Determination index R 2 = (0.013 (As), 0.1348(Hg), 0.1189 (Pb), 0.0079 (Cd) and 0.1577 (Cu)). Runoff water- Fruit: R 2 = (0.109 (As), 0.1586 (Hg), 0.0005 (Pb), 0.0197 (Cd) and 0.0065 (Cu)); statistically it indicates that there is no linear correlation. interpreting for each unit in mg/Kg of each heavy metal that takes the independent variable of contaminated soil and water, there is an increase or decrease in the concentration of metals in the fruit, according to values of the angular coefficient in mg/Kg (As, Hg, Pb, Cd and Cu), according to Pearson, significance (α=0.05) was higher, accepting the null hypothesis, rejecting the alternative hypothesis. Conclusion: the concentrations of heavy metals found in the production fields do not statistically influence the concentration of metals in the fruits.
