A reliable estimate of these parameters from easily measurable soil properties is therefore important. So, the correlations of the transport parameters for one metalloid compound (NaAsO <sub> <font size="2">2 </font> </sub> </font> <font color="#000000">), six heavy metal compounds (Cd(NO </font> <sub> <font color="#000000" size="2">3 </font> </sub> <font color="#000000">) </font> <sub> <font color="#000000" size="2">2 </font> </sub> <font color="#000000">, Pb(NO </font> <sub> <font color="#000000" size="2">3 </font> </sub> <font color="#000000">) </font> <sub> <font color="#000000" size="2">2 </font> </sub> <font color="#000000">, Ni(NO </font> <sub> <font color="#000000" size="2">3 </font> </sub> <font color="#000000">) </font> <sub> <font color="#000000" size="2">2 </font> </sub> <font color="#000000">, ZnCl </font> <sub> <font color="#000000" size="2">2 </font> </sub> <font color="#000000">, CuSO </font> <sub> <font color="#000000" size="2">4 </font> </sub> <font color="#000000"> and Co(NO </font> <sub> <font color="#000000" size="2">3 </font> </sub> <font color="#000000">) </font> <sub> <font color="#000000" size="2">2 </font> </sub> <font color="#000000">), two pesticides (cartap and carbendazim) and one inert salt (CaCl </font> <sub> <font color="#000000" size="2">2 </font> </sub> <font color="#000000">) with some basic properties of eight agricultural soils of Bangladesh were investigated. The purpose of this study was to generate information for development of non-parametric pedo-transfer functions for reactive solute transport through soils. The transport experiments with the solutes were done in repacked soil columns under unsaturated steady-state water flow conditions. The major solute-transport parameters – velocity of transport ( </font> <i style="mso-bidi-font-style: normal;"> <font color="#000000">V </font> </i> <font color="#000000">), dispersion coefficient ( </font> <i style="mso-bidi-font-style: normal;"> <font color="#000000">D </font> </i> <font color="#000000">), dispersivity ( </font> </span> <span style=’line-height: 115%; font-family: Symbol; font-size: 10pt; mso-ascii-theme-font: major-latin; mso-fareast-font-family: "Times New Roman"; mso-hansi-theme-font: major-latin; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: TR; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-ascii-font-family: Cambria; mso-hansi-font-family: Cambria; mso-char-type: symbol; mso-symbol-font-family: Symbol;’> <span style="mso-char-type: symbol; mso-symbol-font-family: Symbol;"> <font color="#000000">l </font> </span> </span> <span style=’line-height: 115%; font-family: "Cambria","serif"; font-size: 10pt; mso-ascii-theme-font: major-latin; mso-fareast-font-family: "Times New Roman"; mso-hansi-theme-font: major-latin; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: TR; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;’> <font color="#000000">), retardation factor ( <i style="mso-bidi-font-style: normal;">R </i> </font> <font color="#000000">) and Peclet number ( </font> <i style="mso-bidi-font-style: normal;"> <font color="#000000">P </font> </i> <font color="#000000">) – were determined by analysing solute breakthrough curves (BTCs). The basic soil properties pertinent to solute transport: clay content, median grain diameter (D </font> <sub> <font color="#000000" size="2">50 </font> </sub> <font color="#000000">), pore-size distribution index ( </font> <i style="mso-bidi-font-style: normal;"> <font color="#000000">n </font> </i> <font color="#000000">), bulk density ( </font> </span> <font color="#000000"> <span style=’line-height: 115%; font-family: Symbol; font-size: 10pt; mso-ascii-theme-font: major-latin; mso-fareast-font-family: "Times New Roman"; mso-hansi-theme-font: major-latin; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: TR; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-ascii-font-family: Cambria; mso-hansi-font-family: Cambria; mso-char-type: symbol; mso-symbol-font-family: Symbol;’> <span style="mso-char-type: symbol; mso-symbol-font-family: Symbol;">r </span> </span> <span style=’line-height: 115%; font-family: "Cambria","serif"; font-size: 10pt; mso-ascii-theme-font: major-latin; mso-fareast-font-family: "Times New Roman"; mso-hansi-theme-font: major-latin; mso-bidi-font-family: "Times New Roman"; mso-ansi-language: TR; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;’>), organic carbon content (C) and pH were determined.
