Furthermore, as transport models incorporate the metal distribution coefficient (and most usually the linear distribution coefficient) into the overall retardation factor, so the study suggests areas for research and experimentation that may be key to incorporate curvilinear distribution coefficients into the transport models instead of a linear partition coefficient.

The purposes of this investigation were to (i) study the effectiveness of raising soil pH to minimise Cd concentration in wheat grain, (ii) determine the impact of soil type on the uptake response slopes (transfer coefficients) of Cd from soil to grain in relation to soil pH, and (iii) test a possible relationship between soil affinity, as measured by the distribution coefficient, and the transfer coefficients.
