RCRA requirementsU194As stipulated in 40 CFR 261.33, when 1-propanamine, as a commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or a manufacturing chemical intermediate, becomes a waste, it must be managed according to Federal and/or State hazardous waste regulations. Also defined as a hazardous waste is any residue, contaminated soil, water, or other debris resulting from the cleanup of a spill, into water or on dry land, of this waste. Generators of small quantities of this waste may qualify for partial exclusion from hazardous waste regulations (40 CFR 261.5).
TSCA requirementsPursuant to section 8(d) of TSCA, EPA promulgated a model Health and Safety Data Reporting Rule. The section 8(d) model rule requires manufacturers, importers, and processors of listed chemical substances and mixtures to submit to EPA copies and lists of unpublished health and safety studies. 1-Propanamine is included on this list.

Environmental fateTERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 43(SRC), determined from a log Kow of 0.48(2) and a regression-derived equation(3), indicates that propylamine is expected to have very high mobility in soil(SRC). The pKa of propylamine is 10.71(4), indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5). Volatilization of propylamine from moist soil surfaces is not expected to be an important fate process given its cationic state(SRC). Propylamine is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 310 mm Hg(6). Biodegradation of propylamine is expected to occur(7-9)a 102% theoretical BOD was measured after 13 days using a non-activated sludge inoculum(7).AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 43(SRC), determined from a log Kow of 0.48(2) and a regression-derived equation(3), indicates that propylamine is not expected to adsorb to suspended solids and sediment(SRC). A pKa of 10.71(4) indicates propylamine will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(5). According to a classification scheme(6), an estimated BCF of 3(SRC), from its log Kow(2) and a regression-derived equation(7), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Biodegradation of propylamine is expected to occur(8-10)a 102% of theoretical BOD was measured after 13 days using a non-activated sludge inoculum(8).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), propylamine, which has a vapor pressure of 310 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase propylamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be 12 hours(SRC), calculated from its rate constant of 3.3X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Propylamine does not contain chromophores that absorb at wavelengths >290 nm(4) and therefore is not expected to be susceptible to direct photolysis by sunlight(SRC).
Food survey valuesThe following naturally occuring concns of propylamine (in mg/kg) were detected in various food products from W Germany: fresh rutabaga, 5.0paprika, 2.3paprika brine, 10.6cucumber, 0.1-7.5pepperoni, 1.4pickled onions, 1.8celery, 2.7cheese, 2-8.7brown bread, 1.6freeze-dried coffee and coffee extract, trace-0.5(1). Propylamine has been qualitatively detected in wine, beer, rice, barley, malt, and corn(2,3).
Adverse effectsOccupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.
Exposure routesThe substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Serious local effects by all routes of exposure.
Milk Concentrations... The presence of volatile aliphatic amines ... in human breast milk and amniotic fluid /was measured/ to assess their role in neonatal hypergastrinemia. These volatile nitrogenous amino acid metabolites have been previously demonstrated to stimulate gastrin release in in vivo and in vitro laboratory preparations. ... The present study ... demonstrated that these gastrin-stimulatory volatile amines were present in significant concentrations in breast milk during the first several weeks after parturition and in amniotic fluid. The individual amines that were identified in both human milk and amniotic fluid samples were methylamine, dimethylamine, ethylamine, trimethylamine, propylamine, isobutylamine, and butylamine. This study provides indirect evidence to support the possibility that the hypergastrinemia measured in the fetus/neonate during the period immediately before and after birth may be attributable, in part, to the ingestion of fluid containing high concentrations of gastrin-stimulating amines.
Ecotoxicity excerpts/OTHER TERRESTRIAL SPECIES/ ... This research compared the toxicity and inhibition caused by three aliphatic amines (n-propylamine, ethylmethylamine, and trimethylamine) and their chlorinated derivatives. ... Acute toxicity assays were conducted by using a Microtox system with Phosphobacterium phosphoreum (also known as Vibrio fischeri) for the aliphatic amine compounds and their corresponding chlorinated derivatives, as identified by membrane introduction mass spectrometry (MIMS). Inhibition tests were conducted by using the oxygen utilization rate test with an enhanced nitrifier culture. ... Trimethylamine and n-propylamine caused greater inhibition to nitrifiers than did ethylmethylamine under similar concentrations. Nitrifier inhibition from these amines increased after chlorination.
Plant ConcentrationsPropylamine has been identified in rice, corn, and barley(1) and occurs naturally in various species of marine algae(2). Latakia tobacco leaf has been found to contain propylamine(3). Propylamine has been detected in medicinal plant root samples collected from Nigeria, Africa, concn not specified(4).
Signs and SymptomsCough. Sore throat. Laboured breathing. Shortness of breath. Symptoms may be delayed.Redness. Pain. Serious skin burns.Watering of the eyes. Redness. Pain. Blurred vision. Severe burns. Loss of vision.Burns in mouth and throat. Burning sensation in the throat and chest. Abdominal pain. Vomiting. Diarrhoea. Shock or collapse.
Effluent ConcentrationsA propylamine 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(1). In a laboratory study, propylamine was detected in the automobile exhaust of two gasoline fueled vehicles, concn not specified(2). An estimated 600 tons of propylamine are annually released in industrial effluents from industrial manufacturers (rubber chemicals, dyestuffs, pharmaceuticals, agricultural chemicals, corrosion inhibitors, textile and leather finishing resins) and users of the compound(3).
ICSC Environmental DataThe substance is harmful to aquatic organisms.
Soil Adsorption/MobilityThe Koc of propylamine is estimated as 43(SRC), using a log Kow of 0.48(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that propylamine is expected to have very high mobility in soil. The pKa of propylamine is 10.71(4), indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
Atmospheric standardsThis action promulgates standards of performance for equipment leaks of Volatile Organic Compounds (VOC) in the Synthetic Organic Chemical Manufacturing Industry (SOCMI). The intended effect of these standards is to require all newly constructed, modified, and reconstructed SOCMI process units to use the best demonstrated system of continuous emission reduction for equipment leaks of VOC, considering costs, non air quality health and environmental impact and energy requirements. Propylamine is produced, as an intermediate or a final product, by process units covered under this subpart.
CERCLA reportable quantitiesPersons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 5000 lb or 2270 kg.
