Two alternatives for the rapid simultaneous quantification of six sulfonylurea herbicides and five of their main degradation products in natural water are proposed. For concentration, the compounds(More)
A new analytical procedure is proposed for monitoring nicosulfuron (sulfonylurea herbicide) in aquatic mesocosms derived from complex ecosystems. The approach is based on alternate use of the anionic(More)
The degradation of the pesticide metsulfuron methyl induced by excitation of iron(III) aqua complexes was studied at 365 nm. The process involved the formation of hydroxyl radicals and was shown to(More)
