ENVIRONMENTAL FATE

Acetochlor's production may result in its release to the environment through various waste streams; its use as a herbicide will result in its direct release to the environment. If released to air, a vapor pressure of 1.6710-7 mm Hg at 20 deg C indicates acetochlor will exist in both the vapor and particulate phases in the atmosphere. Vapor-phase acetochlor will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 2.6 hours. Particulate-phase acetochlor will be removed from the atmosphere by wet or dry deposition. An aqueous solution of acetochlor irradiated for 24 hours in a quartz reactor resulted in a light spectrum of the arch at 311-437 nm with the most intensive emission at 360 nm; therefore acetochlor may be susceptible to direct photolysis by sunlight. If released to soil, acetochlor is expected to have high to moderate mobility based upon a Koc range of 98.5 to 335. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 2.710-10 atm-cu m/mole. Acetochlor was degraded 8 to 15% in a sandy loam over the course of a 48 day incubation period, indicating that biodegradation is an important environmental fate process in soil. If released into water, acetochlor is not expected to adsorb to suspended solids and sediment based upon the Koc range. The half-life of acetochlor in a sewage sludge was determined to be 17.2 hours, indicating that biodegradation may be an important environmental fate process in water. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. An estimated BCF of 250 suggests the potential for bioconcentration in aquatic organisms is high, provided the compound is not metabolized by the organism. Hydrolysis has been described as first-order with half-lives in river water of 1386, 2310 and 2310 days at pH 4, pH 7 and pH 10, respectively. Occupational exposure to acetochlor may occur through inhalation and dermal contact with this compound at workplaces where acetochlor is produced or used. Monitoring data indicate that the general population residing in the US Corn Belt may be exposed to acetochlor via dermal contact with contaminated water and rainfall. (SRC)

Usage: Herbicide discovered and introduced by Monsanto Co. Manufacturers: Dow AgroSciences; ÉMV; Monsanto; Nitrokmia; Sharda; Sinon; Sundat. Inhibits cell division by blocking protein synthesis; more recent research suggests chloroacetamides may inhibit synthesis of very long chain fatty acids. Maize tolerance of chloroacetamides is due mainly to conjugation with glutathione; P450 metabolism may also be a factor.

Application: Selective herbicide, absorbed mainly by the shoots and secondarily by the roots of germinating plants. Used pre-emergence or pre-plant to control annual grasses, certain annual broad-leaved weeds and yellow nutsedge in maize (at 3 kg/ha), peanuts, soya beans, cotton, potatoes and sugar cane.
