In this study, a brief history related to mathematical modeling of minerals uptake by plants from soil is presented. Thereafter, a simulation model called LINN is developed that will have the main task of providing a link between the results predicted by the existing mathematical models and/or measured values (from real experiments) and health impacts as stipulated elsewhere in the literatures. LINN model is built on MS-OFFICE (Access). Six metallic trace elements (MTE) that are known to be dangerous to the ecosystem (As, Cd, Cr, Hg, Ni and Pb) can be evaluated by LINN. This program provides general descriptions on impacts that may happen to plants and/or human beings when these elements are present in the soils at levels exceeding the standard limits set by the regulatory organs i.e. World Health Organization (WHO). However, LINN does not differentiate Short Communication Lema et al.; IJPSS, 5(2): 117-126, 2015; Article no.IJPSS.2015.066 118 impacts related to MTEs present at levels just above the standard limits from levels extremely higher than the standard limits. |
