Abstract

The s-triazines terbutryn and terbuthylazine are currently used in Italy for weed control. A possible reaction of these compounds in the environment is N-nitrosation. Experiments performed in 10 mM CaCl2 as a model of soil water indicated that N-nitrosation is favored only at low pH values and that the N-nitroso derivatives are fairly stable. In the presence of soil either parent compounds or N-nitroso derivatives are strongly adsorbed. These results seem to indicate that the possibility of formation of N-nitrosoterbuthylazine and N-nitrosoterbutryn in common agricultural soil is very remote.
