MAHECHA-PULIDO, Juan D.; TRUJILLO-GONZALEZ, Juan M.  e  TORRES-MORA, Marco A.. Analysis of Studies in Heavy Metals in Agricultural Areas of Colombia. Orinoquia [online]. 2017, vol.21, suppl.1, pp.83-93. ISSN 0121-3709.  https://doi.org/10.22579/20112629.434.

The soil resource offers fundamental ecosystem services, among which stand out the support for food production and its importance in mitigating the effects of climate change due to carbon dynamics. However, anthropic activities such as urbandensification, industrialization and mainly agriculture contribute elements such as heavy metals, responsible for soil degradation in some regions of the planet. Naturally the soils in their geochemical base contain heavy metals, in the majority of the regions these concentrations do not represent environmental risk. In this sense, the purpose of the present investigation was to compile the studies of heavy metals developed in agricultural production systems in Colombia to establish a baseline, which allows identifying future research needs in this subject. Among the results found, it was identified that the heavy metals studied in the country are Cd> Pb> Hg> Cr> Ni> Cu = Zn = As> Mn> Fe, highlighting Cd, Pb, Hg and Cr. However in Colombia The scientific production in which heavy metals are related to agricultural production (soil, crops or inputs) is relatively low. Also, these works are located in the central region of the country, evidencing that regions such as the Orinoquia considered as the border and agricultural pantry of the country, only three studies that were published in recent years are reported. Finally, this highlights the importance of generating research on reference values for these elements in Colombian soils, which allow the establishment of monitoring and evaluation programs in possible cases of contamination
