Some chemical degradation may occur in soils. In aquatic environments, amitrole is not expected to breakdown by hydrolysis or photolysis, to volatilize, nor to bioaccumulate in aquatic organisms. The biodegradation half-life for amitrole in water is about 40 days. Degradation of amitrole in open waters may occur through oxidation by other chemicals. Amitrole may persist in surface waters for longer than 200 days.
Plants are able to metabolize amitrole.
There is a slight fire hazard when amitrole is exposed to heat or flame. Amitrole is mildly corrosive to iron, aluminum, copper and copper alloys. Soluble in chloroform, ethanol and methanol. Slightly soluble in acetonitrile, ethyl acetate and methyl chloride. Farm Chemicals Handbook.
