The objective of this study was to evaluate the determination of cadmium, chromium, and lead in Vaccinium corymbosum L. "blueberry", coming from a market and a supermarket located in the district of Chorrillos-Lima. Due to their condition, in the case of the market, the samples were collected from four points of sale, to obtain a representative sample. In the case of the Supermarket, the sample was unique. By means of the instrumental method of atomic absorption spectrophotometry, the quantification of the heavy metals of cadmium, chromium and lead was carried out, using the atomic absorption spectrophotometer equipment. Concentrations of <0.05 were determined; <0.05; 0.275 ug / gr in cadmium, chromium, and lead, respectively, in blueberries collected from a supermarket and concentrations of <0.05; 0.137; 0.288 ug / gr in cadmium, chromium and lead, respectively, in blueberries ...
