Carbamates

PROPHAM is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

The best way to dispose of small amounts of excess pesticides is to use them - apply them - according to the directions on the label. If you cannot use them, ask your neighbors whether they have a similar pest control problem and can use them. If all of the remaining pesticide cannot be properly used, check with your local solid waste management authority, environmental agency, or health department to find out whether your community has a household hazardous waste collection program or a similar program for getting rid of unwanted, leftover pesticides. These authorities can also inform you of any local requirements for pesticide waste disposal.|Safe Disposal of Pesticides. An empty pesticide container can be as hazardous as a full one because of residues left inside. Never reuse such a container. When empty, a pesticide container should be rinsed carefully three times and the rinsewater thoroughly drained back onto the sprayer or the container previously used to mix the pesticide. Use the rinsewater as a pesticide, following label directions. Replace the cap or closure securely. Dispose of the container according to label instructions. Do not puncture or burn a pressurized container like an aerosol - it could explode. Do cut or puncture other empty pesticide containers made of metal or plastic to prevent someone from reusing them. Wrap the empty container and put it in the trash after you have rinsed it.

A system for removing pesticides from the wash water produced by pesticide applicators as they clean their equipment has been developed. The system incorporates a two-stage treatment process. The first step is the flocculation/coagulation and sedimentation of the pesticide contaminated wash water. The supernatant from the first step is then passed through activated C columns.|If a spill occurs, clean it up promptly. Don't wash it away. Instead, sprinkle the spill with sawdust, vermiculite, or kitty litter. Sweep it into a plastic garbage bag, and dispose of it as directed on the pesticide product label.|After Applying a Pesticide, Indoors or Outdoors. To remove pesticide residues, use a bucket to rinse tools or equipment three times, including any containers or utensils that you used when mixing the pesticide. Then pour the rinsewater into the pesticide sprayer and reuse the solution by applying it according to the pesticide product label directions. After applying any pesticide wash your hands and any other parts of your body that may have come in contact with the pesticide..To prevent tracking pesticides inside, remove or rinse your boots or shoes before entering your home. Wash any clothes that have been exposed to a lot of pesticide separately from your regular wash.

Avoid breathing of vapor or spray mist. Use with adequate ventilation.|Wear the items of protective clothing the label requires: for example, non-absorbent gloves (not leather or fabric), rubber footwear (not canvas or leather), a hat, goggles, or a dust-mist filter. If no specific clothing is listed, gloves, long-sleeved shirts and long pants, and closed shoes are recommended. You can buy protective clothing and equipment at hardware stores or building supply stores.|Indoor Applications. If the label directions permit, leave all windows open and fans operating after the application is completed. If the pesticide product is only effective in an unventilated (sealed) room or house, do not stay there. Put all pets outdoors, and take yourself any your family away from treated areas for at least the length of time prescribed on the label. Apply most surface sprays only to limited areas such as cracks; don't treat entire floors, walls, or ceilings. Don't let pesticides get on any surfaces that are used for food preparation. Wash any surfaces that may have pesticide residue before placing food on them.|Indoor Applications. When using total release foggers to control pests, use no more than the amount needed and to keep foggers away from ignition sources (ovens, stoves, air conditioners, space heaters, and water heaters, for example). Foggers should not be used in small, enclosed places such as closets and cabinets or under tables and counters.|Outdoor Applications. Never apply pesticides outdoors on a windy day (winds higher than 10 mph). Position yourself so that a light breeze does not blow pesticide spray or dust into your face.

U373; A toxic waste when a discarded commercial chemical product or manufacturing chemical intermediate or an off-specification commercial chemical product or manufacturing chemical intermediate.

Persons 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 1 lb. The toll free number of the NRC is (800) 424-8802. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b). The Agency may adjust the statutory RQ for this hazardous substance in a future rulemaking; until then the statutory one-pound RQ applies.

U373; As stipulated in 40 CFR 261.33, when isopropyl phenylcarbamate, 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).

Isopropyl phenylcarbamate was not detected in 35 wells from 3 counties in CA between July 1, 1994 and June 30, 1995(1).

Isopropyl phenylcarbmate's production may result in its release to the environment through various waste streams; it's former use in the US as a herbicide(1) will have resulted in its direct release to the environment(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), measured Koc values ranging from 51 to 65(2,3) indicate that isopropyl phenylcarbmate is expected to have very high mobility in soil(SRC). Volatilization of isopropyl phenylcarbmate from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 1.8X10-7 atm-cu m/mole(SRC), derived from a vapor pressure of 1X10-4 mm Hg(4) and a water solubility of 1.79 mg/L(5). Isopropyl phenylcarbmate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure. Pure culture studies show that phenylcarbates are biodegraded to catechol which is then further metabolized in the TCA cycle(6). Isopropyl phenylcarbamate biodegrades more rapidly in soil that was previously treated with isopropyl phenylcarbamate(7). After 60, days 70% of isopropyl phenylcarbamate from soil previously treated with the pesticide was degraded into CO2 compared to the 20% degraded by soil that had never been treated with the pesticide(7). Similar results were obtained with soil that had been treated with the pesticide carbetamide(8). Isopropyl phenylcarbamate is stable in the presence of anaerobic microorganisms(9).|TERRESTRIAL FATE: Isopropyl phenyl carbamate was applied as a spray on sandy loam soil taken from Bagbroke Hill Farm(1). The soil was then repotted and Italian rye grass was grown under greenhouse environment. Analysis of dry weight samples showed that isopropyl phenylcarbamate had a half life of less than 4.5 weeks in soil where Italian rye grass was grown(1).|AQUATIC FATE: Based on a classification scheme(1), measured Koc values ranging from 51 to 65(2,3) indicate that isopropyl phenylcarbmate is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(4) based upon an estimated Henry's Law constant of 1.8X10-7 atm-cu m/mole(SRC), derived from a vapor pressure of 1X10-4 mm Hg(5) and a water solubility of 1.79 mg/L(6). Isopropyl phenylcarbmate has been shown to be resistant to hydrolysis in the environment(7). According to a classification scheme(8), an estimated BCF of 20(SRC), from its log Kow of 2.6 (9) and a regression-derived equation(10), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Pure culture studies show that phenylcarbamates are biodegraded to catechol which is then further metabolized in the TCA cycle(11). Studies show that biodegradation in water may be an important fate process(12,13); however this reaction may be dependent on concentration of the sample(12). Isopropyl phenylcarbamate is stable in the presence of anaerobic microorganisms(14).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), isopropyl phenylcarbmate, which has a vapor pressure of 1.4X10-4 mm Hg at 25 deg(2), is expected to exist solely as a vapor phase in the ambient atmosphere. Vapor-phase isopropyl phenylcarbmate 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 7.3 hours(SRC), calculated from its rate constant of 5.2X10-11 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Isopropyl phenylcarbmate does not contain chromophores that absorb at wavelengths >290 nm and has been shown not to be susceptible to direct photolysis by sunlight(4).

The carbamate herbicide propham photodecomposes by at least two pathways.|The rate constant for the vapor-phase reaction of isopropyl phenylcarbmate with photochemically-produced hydroxyl radicals has been estimated as 5.2X10-11 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 7.3 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). Isopropyl phenylcarbmate has been shown to be resistant to hydrolysis in the environment(2). Isopropyl phenylcarbmate does not contain chromophores that absorb at wavelengths >290 nm and has been shown not to be susceptible to direct photolysis by sunlight(3).

An estimated BCF of 20 was calculated for isopropyl phenylcarbmate(SRC), using a log Kow of 2.6(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

INCR FIELD MOISTURE CAPACITY & TEMP GREATLY INCR VAPOR LOSSES TO POINT WHERE @ 35 °C VOLATILITY MAY BE MAJOR MEANS OF DISSIPATION.|The Henry's Law constant for isopropyl phenylcarbmate is estimated as 1.8X10-7 atm-cu m/mole(SRC) derived from a vapor pressure of 1X10-4 mm Hg(1) and a water solubility of 1.79 mg/L(2). This Henry's Law constant indicates that isopropyl phenylcarbmate is expected to be essentially nonvolatile from water and moist soil surfaces(2). Isopropyl phenylcarbmate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

GROUNDWATER: Isopropyl phenylcarbamate was detected but not quantified in 1 out of 1,060 wells sampled in the US from 1971-1991(1). In a separate study, isopropyl phenylcarbamate was detected with 0.5% frequency in the public stream water of Denver CO with a maximum concentration of 0.07 ug/L(2).|RAIN/SNOW/FOG: Isopropyl phenylcarbamate was not detected in rainwater collected from Konigsmoor, Germany during 1996(1).

Isopropyl phenylcarbamate was detected in boiled potatoes(1). There were 97 reports of isopropyl carbamate in imported food in Sweden from 1990-1994(2).

Main route of excretion of propham by goat was via urine. Small amount appeared in milk and feces.

Occupational exposure and general population exposure should be low or non-existent since isophenyl carbamate is no longer produced or used in the US (1998). In the past, isopropyl phenyl carbamate was applied directly to the potato, clover, lentil, sugar beet, safflower, pea, flax and spinach crops as an herbicide and exposure to this compound was primarily by dermal contact and in the field where it was applied.
