ENVIRONMENTAL FATE

Linuron's production and use as a herbicide is expected to result in its direct release to the environment. Releases may also occur during production, formulation, preparation for spraying, cleanup, transport, and storage. If released to air, a vapor pressure of 1.43×10-6 mm Hg at 25 deg C indicates linuron will exist in both the vapor and particulate phase. Vapor-phase linuron will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 12 hours. Linuron absorbs light in the environmental UV spectrum and may undergo direct photolysis. Particulate-phase linuron will be removed from the atmosphere by wet and dry deposition. If released to soil, linuron is expected to have low mobility in soil based upon an experimental Koc ranging from 555 to 987. Volatilization from moist soil surfaces is not expected to be an important fate process based upon its Henry's Law constant of 1.97×10-9 atm-cu m/mole. Linuron is not expected to volatilize from dry soil surfaces based upon its vapor pressure of 1.43×10-6 mm Hg. In most soils and at normal application rates, linuron biodegrades within 3-4 months, and half-lives of as low as 22 days have been observed. Linuron biodegrades in soil more rapidly at higher soil moistures and temperatures. Photolysis of linuron on surface soils may also be an important degradation pathway. Phenyl-labeled C-14 linuron degraded with a half-life >15 days on silt loam soil irradiated continuously with a Pyrex glass filtered xenon arc light at 25 deg. After 15 days of irradiation, the soil contained 78.8% of the recovered radioactivity as parent linuron. If released into water, linuron is expected to adsorb to suspended solids and sediment based upon its experimental Koc values and reported adsorption data. Biodegradation of linuron is also expected to occur in water. Half-lives ranging from 7.2 days in stagnant ditch water to 10 weeks in lake water have been reported. Photolysis of linuron is also expected to occur in surface waters. In one experiment, 43% of linuron exposed to sunlight outdoors was photolyzed in 24 days. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's experimental Henry's Law constant. An experimental BCF ranging from 13 to 49 suggests that the potential for bioconcentration in aquatic organisms is low to moderate. Hydrolysis of linuron is not expected to occur in water except at high pH levels (> 9). Occupational exposure to linuron may occur through inhalation and dermal contact with this compound at workplaces where linuron is produced or used, or through dermal contact with linuron-treated soil or vegetation. Monitoring data indicate that the general population may be exposed to linuron via ingestion of contaminated vegetables, primarily carrots, and ingestion of contaminated water. (SRC)
