From Eqns 1 and 2 it can be seen that the two models had a high coefficient of determination ([R.sup.2]) and a small standard error of the estimate (SE), which means the chemical transformation of Cd in calcareous soil treated with the two P-containing acidify
agents was mainly associated with the addition level of P in water-soluble form and not soil pH.

water, but it does kill bacteria.
Critics of the ocean-disposal idea argue, however, that the added carbon dioxide will acidify
