Abstract
Chlorsulfuron dissipation in samples from a river was followed (in lab oratory) for 8 months and it was related to temperature (imposed at 25 degrees and 40 degrees C), as well as to pH, Biological and Chemical Oxygen Demand, Suspended Solids, and Electrical Conductivity of the sa mples. At 25 degrees C the half-life was shorter in river than in dist illed water, and on increasing temperature it decreased 10-20 folds. H igher pHs (in the 7.96-8.70 range) and lower BOD values significantly decreased the half-life. The other parameters did not significantly af fect dissipation.
