ROSALES-HUAMANI, Jimmy et al. Identification of Cadmium and Lead in cocoa crops located in the Satipo - Junin zone. Tecnia [online]. 2021, vol.31, n.2, pp.83-89.  Epub June 01, 2021. ISSN 0375-7765.  http://dx.doi.org/10.21754/tecnia.v21i2.1062.

There is now a serious problem in cocoa crops in various regions of Peru due to the presence of heavy metals in these crops. The high concentrations of heavy metals in cocoa crops prohibit their export because the European Community has established food regulations indicating the maximum permissible levels of heavy metals and other elements in food. It is considered that the possible reasons for the contamination of the Cd in cocoa crops may come from natural activities such as volcanic activities, erosion processes and sedimentation in rocks that contain minerals with a high content of these heavy metals. This contamination is also produced by anthropogenic activities such as mining of associated deposits, agriculture (use of fertilizers), smelting of minerals and burning of fossil fuels. Due to the fact that there is currently no information on the content levels of heavy metals as Cadmium (Cd) and Lead (Pb) in a study area located in Satipo-Junín. In this work, we study this region, using a methodology to obtain the concentrations of Cd and Pb metals present in the soil of foreign-type cocoa crops. As a consequence of this study we determined and concluded that the concentrations obtained of Cd and Pb in soils are inferior to the standards established by the Ministry of Environment (MINAM), in addition we generated the geochemical map of the study zone with these metals.
