transport of pathogenic bacteria has been recently considered a major source surface and subsurface water contaminations. soil could affect transport or filtering of bacteria depending on its physical and chemical properties. calcium carbonate and calcium sulfate are two important minerals of arid and semi-arid soils that their effect on bacteria transport has not been investigated, yet. in thi...
The aim of this work is to model the occurrence and intensity of calcium carbonate loss in calcareous forest soils under Mediterranean conditions. We have used 193 Spanish forest soils found on limestone parent material considered highly calcareous materials. This data set came from FOREDAF, a database containing 2200 complete soil profiles and all of them covered by forest stands (mainly domin...

Dr. Troels Ring, MD, Medical Department C, Aalborg Hospital, Aalborg (Denmark) Dear Sir, Two recent papers comparing calcium carbonate with calcium acetate both conclude that calcium acetate is the better phosphorus binder. In the paper by Caravaca et al. [1], the serum phosphate concentration was 1.80 ± 0.50 (SD) mmol/l while on calcium acetate, and 1.93 ± 0.48 on calcium carbonate in a parall...
