| RCRA 요건 | U192As stipulated in 40 CFR 261.33, when pronamide, 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). |

Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Propyzamide is found on List A, which contains most food use pesticides and consists of the 194 chemical cases (or 350 individual active ingredients) for which EPA issued registration standards prior to FIFRA, as amended in 1988.

| Reactivity Profile | 3,5-DICHLORO-N-(1,1-DIMETHYL-2-PROPYNYL)BENZAMIDE is a chlorinated amide. Organic amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). |

| 환경 거동 | TERRESTRIAL FATE: MOVEMENT OF PRONAMIDE IS GREATEST IN COARSE TEXTURED SOILS. LEACHING OF MOST SOIL RESIDUALS OCCURS IN LOAMY SANDS AND IN SILT LOAMS.TERRESTRIAL FATE: Spring spraying of 3 kg kerb/ha controlled weeds and left 0.15 mg propyzamide/kg in harvested flower heads of Anthemis nobilis and the top 5 cm of soil. At 5-10 cm, the residue was 0.056 mg/kg. The rate of herbicide decay depended more on the temp than on the soil moisture.TERRESTRIAL FATE: Based on a recommended classification scheme(1), experimental Koc values from 200-800(2-4), indicate that pronamide will have low to moderate mobility in soil(SRC). Very little leaching of pronamide occurs in most soil types as it is readily adsorbed on organic matter and other colloidal exchange sites(5,6). Pronamide is degraded via both biotic and abiotic pathways to a number of transformation products in soils(7,SRC). Initial transformation reactions in soil include cyclization to form 2-(3,5-dichlorophenyl)-4,4-dimethyl-5-methyleneoxazoline followed by hydrolysis to N-(1,1-dimethylacetonyl)-3,5-dichlorobenzamide(7). These two transformation products and small amounts of unchanged pronamide represented over 96% of the herbicide recovered 90 days after soil treatment(7). Other degradation products were present in trace amounts and were the result of alterations in the terminal carbons of the propynyl side chain(7). Transformation to the cyclized and subsequent hydrolysis products occurred about three times more rapidly in a non-sterilized soil as compared to the sterilized soil over a 33 day period(8)formation of carbon dioxide in the non-sterilized, but not in the sterilized soil indicated biological mediation(8).TERRESTRIAL FATE: Loss of pronamide from soil surfaces due to photodecomposition may occur(1,2). The average persistence of pronamide when applied at recommended herbicidal rates is variable (2-9 months) and depends on soil types and climatic conditions with residual activity greater in sandy soils with low organic carbon content(2). The degradation half-life of pronamide in 18 different soil types at 25 °C ranged from 9.5 to 32.4 days(3). The degradation half-life in 5 different soils varied from 23-42 days at 25 °C and from 63-112 days at 15 °C(4). Observed half-life under field conditions in a sandy loam soil varied from 40-80 days(5). Observed half-lives under field conditions averaged about 40 days in 14 different soil types(6). Pronamide had increasingly rapid initial biodegradation rates with increasing numbers of previous treatments(7). Half-lives for pronamide were approximately 45, 35, 22, and 18 days, respectively, in plots treated for the first, second, third, and fourth time(7). Volatilization of pronamide should not be an important fate process from moist or dry soil surfaces(SRC) given an estimated Henry's Law constant of 1.9X10-6 atm-cu m/mole(8,9,SRC) and an experimental vapor pressure of 8.5X10-5 mm Hg, respectively(8). However, under very hot and dry conditions, volatilization has been noted(2).For more Environmental Fate (Complete) data for PRONAMIDE (6 total), please visit the HSDB record page. |

| Soil Adsorption/Mobility | Very little leaching of pronamide occurs in most soil types as it is readily adsorbed on organic matter and other colloidal exchange sites(1). Adsorption distribution experiments with 18 different soil types has shown that, in general, pronamide adsorption increases proportionately with an increase in organic matter content(2). Soil partition coefficients were measured for pronamide in seven soils (organic carbon ranged from 0.01-16.9%pH from 5.2-7.2)Kd values ranged from 0.04-72.2 with higher values corresponding to soils with higher organic carbon content(Koc values of 400-427(SRC))(3). Koc values of 204(4) and 800(5) were measured in soil for this compound. Pronamide had a pesticide leaching potential index value of 36 out of 100 indicating that this pesticide is not likely to leach significantly(6). According to a recommended classification scheme(7), these estimated Koc values suggest that pronamide has low to moderate mobility in soil(SRC). |
