Abstract

In the first part of the paper the Authors deal: with factors causing the enrichment of nitrates in the environment and with relations of these substances to human patology; with biochemical trasformations of the various types of nitric fertilizers; with conditions supporting the leaching of nitrates to ground waters. Sussessively they repost the results of a sistematic reserach carried out in some high nitrates ground-waters. During a period of two years 13 wells and 4 rivers have been periodically observed in order to show possible connections between fertilization interventions and changes of chemical parameters. Obtained results have showed a tendency of nitrates of examined wells to increase in the long run, although found values - for their variability - cannot refer to single fertilization interventions. The Auhtors, finally, suply informations suited to limit contamination of ground-waters by these substances.
