SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 18(SRC), determined from a structure estimation method(2), indicates that isopropyl carbamate is expected to have very high mobility in soil(SRC). Volatilization of isopropyl carbamate from moist soil surfaces is not expected to be important(SRC) given an estimated Henry's Law constant of 7.0X10-8 atm-cu m/mole(SRC), using a fragment constant estimation method(3).|AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 18(SRC), determined from a structure estimation method(2), indicates that isopropyl carbamate is not expected to adsorb to suspended solids and sediment in water(SRC). Isopropyl carbamate is not expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 7.0X10-8 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). According to a classification scheme(5), an estimated BCF of 1.2(3,SRC), from an estimated log Kow(6,SRC), suggests that bioconcentration in aquatic organisms is low(SRC).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), isopropyl carbamate, which has an estimated vapor pressure of 0.17 mm Hg at 25 °C(2,SRC), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase isopropyl carbamate 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 1.3 days(3,SRC).

The rate constant for the vapor-phase reaction of isopropyl carbamate with photochemically-produced hydroxyl radicals has been derived as 1.2X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1,SRC). This corresponds to an atmospheric half-life of about 1.3 days at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1,SRC). Purely aliphatic carbamates are expected to be resistant to hydrolysis under environmental conditions(2). A base-catalyzed second-order rate constant of 6.6X10-5 L/mol-sec(SRC) was estimated using a structure estimation method(2); this corresponds to half-lives of 3300 and 330 years at pH values of 7 and 8, respectively(2,SRC).

An estimated BCF of 1.2 was calculated for isopropyl carbamate(SRC), using an estimated log Kow of 0.40(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF suggests that bioconcentration in aquatic organisms is low(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc for isopropyl carbamate was estimated to be 18(SRC). According to a recommended classification scheme(2), this estimated Koc value suggests that isopropyl carbamate is expected to have very high mobility in soil(SRC).

The Henry's Law constant for isopropyl carbamate is estimated as 7.0X10-8 atm-cu m/mole(SRC) using a fragment constant estimation method(1). This value indicates that isopropyl carbamate will be essentially nonvolatile from water surfaces(2,SRC). Isopropyl carbamate's Henry's Law constant(1,SRC) indicates that volatilization from moist soil surfaces is not expected to occur(SRC).

For immediate first aid: Ensure that adequate decontamination has been carried out. If victim is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep victim quiet and maintain normal body temperature. Obtain medical attention. /Esters and related compounds/|For basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ...
