Chloroturon is a commonly used urea herbicide. It is moderately soluble in water, volatile with a high potential for leaching to groundwater. It is moderately persistent in soil but tends not to be persistent in water due to rapid aqueous photolysis. Chloroturon has a low mammalian toxicity but may bioaccumulate. Whilst it is non-toxic to honeybees it is moderately toxic to birds, earthworms and most aquatic organisms.
