Environmental Impact 1-Aminopropane occurs naturally in various plants, such as tobacco and algae, as a bio-organic degradant, and as a volatile emission product from animal waste. It is released to the environment through effluents from its industrially production and use. If released to the atmosphere, 1-aminopropane is rapidly degraded (estimated half-life of 12 hr) by reaction with photochemically produced hydroxyl radicals. If released to water, 1-aminopropane is physically removed by volatilization. Volatilization half-lives of 2.44 and 26.5 days have been estimated for a shallow (1 m deep) model river and an environmental pond, respectively. Aquatic biconcentration and adsorption to sediment are not expected to be important. If released to soil, 1-aminopropane is expected to be very mobile and easily leached based upon estimated Koc values of less than 50. Evaporation from dry soil is likely to occur. Several screening studies have demonstrated that 1-aminopropane is readily biodegraded by activated and non-activated sludges. The general population is primarily exposed through consumption of food products in which 1-aminopropane apparently occurs as a natural product. Inhalation exposure is possible in localized areas containing large quantities of animal waste, such as cattle yards. Occupational exposure is possible through inhalation and dermal contact at sites of commercial production and use.
Environmental Fate TERRESTRIAL FATE: When released to soil, 1-aminopropane is expected to be very mobile and easily leached based upon estimated Koc values of less than 50. Its relatively high vapor pressure of 307.9 mm Hg at 25 deg C suggests that rapid evaporation from dry surfaces may occur. AQUATIC FATE: 1-Aminopropane is physically removed from water by volatilization. Volatilization half-lives of 2.44 and 26.5 days have been estimated for a shallow (1 m deep) model river and an environmental pond, respectively. Several screening studies have demonstrated that 1-aminopropane is readily biodegraded by activated and non-activated sludges; therefore, biodegradation in natural water may be possible (although not experimentally demonstrated). Aquatic bioconcentration and adsorption to sediment are not expected to be important. ATMOSPHERIC FATE: Based on a vapor- pressure of 307.9 mm Hg at 25 deg C , 1-aminopropane is expected to exist almost entirely in the vapor-phase in the ambient atmosphere(2,SRC). Vapor- phase 1-aminopropane is degraded rapidly in the atmosphere by reaction with photochemically produced hydroxyl radicals (estimated half-life of 12 hours in an average atmosphere).
Drinking Water Impact DRINKING WATER: 1-Aminopropane was qualitatively detected in District of Columbia drinking water . SURFACE WATER: 1-Aminopropane was detected at a concn of 2.9 ppb in samples from the Elbe River in W Germany . EFFL: A 1-aminopropane concn of 400 ppm was detected in a 1980 waste sample which was discharged into the ocean 74 km north of Arebico, Puerto Rico from a pharmaceutical manufacturer .
