- Abstract
The soil is one of the main environmental components, has the function of supporting various life forms, among them, the plants, serving as a substrate for their growth and dissemination. Soil contamination can be dissipated to food, air and groundwater. Due to these possible effects, this work aimed to analyze some soil attributes of an agricultural area in order to determine the vulnerability to the effects of contaminants. The attributes: texture, organic matter and pH, as well as the concentration of heavy metals in the soil samples were evaluated. Three main components were generated to explain 99.30% of the variance in the experiment. Principal component analysis indicated that cadmium, chromium, nickel, lead, copper and sand and silt percentages showed a good correlation with the selected sampling points, indicating possible contamination areas. From the particle size characterization and amount of organic matter, the soil has low efficiency for retention of pesticide residues. The pH values found were not a limiting factor to the good development of the plants. Of the heavy metal concentrations, cadmium was the only one that presented levels above that allowed by the legislation. The soil has been shown to have the potential to make contaminants available to plants and groundwater.
