Comparison of multivariate methods for arsenic estimation and mapping in floodplain soil via portable X-ray fluorescence spectroscopy
Original language description
Rapid, inexpensive, and equally reliable estimates of potentially toxic elements are a necessity, portable X ray fluorescence (pXRF) spectrometry is a handy tool to help achieve such. The current study sought to compare multiple linear regression with three regularized regression models Ridge, Lasso, and ElasticNet ENET for the estimation of total arsenic As using pXRF datasets in polluted temperate floodplain soils of Příbram, Czech Republic. A total of 158 (0-25 cm) floodplain surface soil samples were collected from a specific site in Příbram. Models were evaluated separately and compared based on mean absolute error (MAE), root mean squared error (RMSE) and the coefficient of determination (R2). All four models were able to predict As with good accuracy (MAE and RMSE values of 0,02 and 0,03, respectively, and R2 values ranging from 0,94 to 0,95). As measured via pXRF as well as predicted via the four regression models produced similar spatial variability as shown by the standard laboratory-measur
