Summary

A new mathematical model accurately predicts lanthanide element concentrations in soil and plant samples. While effective for most elements, prediction accuracy decreases for heavier lanthanides at lower concentrations.

Area of Science:

  • Environmental Chemistry
  • Geochemistry
  • Analytical Chemistry

Background:

  • Lanthanide elements are critical trace metals in various environmental and biological systems.
  • Accurate quantification of lanthanides in soil and plants is essential for environmental monitoring and risk assessment.

Purpose of the Study:

  • To develop and validate a mathematical model for predicting lanthanide element concentrations.
  • To assess the model's performance across different environmental matrices and element concentrations.

Main Methods:

  • Development of a predictive mathematical model based on established chemical principles.
  • Validation of the model through comparison of predicted values with measured lanthanide concentrations in soil and plant samples.

Main Results:

  • The model demonstrates good predictive accuracy for lanthanide concentrations in soil samples.
  • The model performs well for most lanthanide elements in plant materials.
  • Prediction accuracy for heavier lanthanide elements diminishes at lower concentration levels.

Conclusions:

  • The developed mathematical model is a valuable tool for estimating lanthanide levels in soil and plant ecosystems.
  • Further research and data are required to extend the model's applicability to other environmental matrices such as aerosols.
