    Abstract
    The rate of urea degradation in seawater was studied under various conditions and the kinetics of urea degradation was evaluated. Urea decomposition experiments showed that the rates and quantity of ammonium oxidation were slower in the relatively polluted waters, resulting in the accumulation of ammonia. The urea decomposing bacteria varied between 7 and 40% among the total heterotrophic bacteria in Velsao Bay, while these were from 15 to 22% near Mormugao. The rate for biological oxidation of urea was 18.6 n mole 1-1 day-1 and for chemical oxidation it was 10.5 n mole 1-1 day-1. The effects of different urea concentration and pH on the nitrogen transformation processes were also studied
