GUZMAN-MORALES, Ambar Rosa et al. Mathematical Modeling of the Behavior of Nickel and Copper in a Contaminated Agroecosystem. Rev Cie Téc Agr [online]. 2025, vol.34  Epub 01-Abr-2025. ISSN 2071-0054.

The need to control the contamination caused by heavy metals is increasingly urgent, which is why it is necessary to study the quality of the soil in order to preserve or improve its productivity for the protection of the environment, animal and human health, and to guarantee food safety. Trace elements in high concentrations in soils are food toxins with negative effects on health that manifest in the long term. The action of some of them has been reported on the increase in cases of cancer, nervous system lesions and genetic diseases in humans, etc. as a result of the consumption of contaminated water and food, whether of animal or plant origin. The objective of this work is to propose mathematical models to predict the behavior of nickel and copper concentrations in an agroecosystem adjacent to the dumping of industrial waste in the municipality of San José de las Lajas. For this purpose, the data on the concentration of heavy metals nickel (Ni) and copper (Cu) provided by the Scientific Group of the Faculty of Agronomy of the UNAH from 2005 to 2018 were taken to predict their behavior based on the use of statistical-mathematical tools until 2034. It was obtained that, according to the mathematical models obtained, these soils should not be used to grow vegetables for consumption, nor allow free grazing of cattle, at least until 10 years after this research.
