Cleanup Methods
1) Ventilate area of spill. 2) For small quantities, sweep onto paper or other suitable material, place in an appropriate container and burn in a safe place (such as a fume hood). Large quantities may be reclaimed.
Land spill: Dig a pit, pond, lagoon, or holding area to contain liquid, or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water.
Water spill: Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the amount spilled. Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.

Strong oxidizers.
2,4-D is a strong acid, & forms water-soluble salts with alkali metals & amines.
Other Preventative Measures
Handle carefully. Do not contaminate water, food or feed by product storage or disposal. ... Do not use spray equipment contaminated with this product for any other purposes unless thoroughly cleaned with a suitable cleaner. ... Do not apply where irrigation water may be contaminated.
Respirators may be used when engineering and work practice controls are not technically feasible, when such controls are in the process of being installed, or when they fail and need to be supplemented. Respirators may also be used for operations which require entry into tanks or closed vessels, and in emergency situations. ... If employees' clothing ... becomes contaminated with 2,4-D, employees should change into uncontaminated clothing before leaving the work premises. Clothing contaminated with 2,4-D should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of 2,4-D from the clothing. If the clothing is to be laundered or otherwise cleaned to remove 2,4-D, the person performing the operation should be informed of 2,4-D's hazardous properties. Non-impervious clothing which becomes contaminated with 2,4-D should be removed promptly and not reworn until the 2,4-D is removed from the clothing.
Eating and smoking should not be permitted in areas where solid 2,4-D is handled, processed, or stored. Employees who handle 2,4-D or liquids containing 2,4-D should wash their hands thoroughly with soap or mild detergent before eating, smoking, or using toilet facilities.
/Individuals/ not wearing protective equipment and clothing should be restricted from areas of spills until cleanup has been completed.
In addition to respirator selection, a complete respiratory protection program should be instituted which includes regular training, maintenance, inspection, cleaning, and evaluation /of equipment/.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.
If material /is/ not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Keep upwind. ... Avoid breathing vapors or dusts. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
Smoking, eating, and drinking before washing should be absolutely prohibited when any pesticide ... is being handled or used. /Pesticides/
/When/ cleaning glassware and spray equipment: wash thoroughly with water and detergent soln. Alcohol or ketone type solvents may be used with ester formulations. Preferably, equipment should not be used for application of other pesticides or fertilizers.
The worker should immediately wash the skin when it becomes contaminated.
Work clothing that becomes wet or significantly contaminated should be removed and replaced.
Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises.
Handle carefully. Do not contaminate water, food, or feed by product storage or disposal. Do not use spray equipment contaminated with this product for any other purposes unless thoroughly cleaned with a suitable cleaner. Do not apply where irrigation water may be contaminated.
Protective Equipment and Clothing
If the use of respirators is necessary, the only respirators permitted are those that have been approved by the Mine Safety and Health Administration (formerly Mining Enforcement and Safety Administration) or by the National Institute for Occupational Safety and Health. ... Employees should be provided with and required to use impervious clothing, gloves, face shields (eight-inch minimum), and other appropriate protective clothing necessary to prevent repeated or prolonged skin contact with 2,4-D or liquids containing 2,4-D. ... Employees should be provided with and required to use dust- and splash-proof safety goggles where 2,4-D or liquids containing 2,4-D may contact the eyes.
Wear appropriate personal protective clothing to prevent skin contact.
Wear appropriate eye protection to prevent eye contact.

Disposal Methods
Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste numbers D016 and U240, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste.
Landfill: Recommendable method: Incineration. Not recommendable method: Discharge to sewer. Peer-review: Incinerate at high temp or PCDDs may be formed.
Incineration and landfill: 2,4-D /2,4-dichlorophenoxyacetic acid/ is known to be readily detoxified by soil microorganisms and at low dosages is normally decomposed in one to four weeks. The detection of 2,4-dichlorophenol, 4-chlorocatechol, chloromuconic and succinic acids from either soil or pure culture studies suggests a sequence of reactions involving ring hydroxylation and cleavage and further metabolism of the open chain structure to carbon dioxide. The non-persistence and detoxification of 2,4-D in soil indicate that burial in non-crop areas away from water supplies would be an acceptable method for the disposal of small quantities of 2,4-D. Incineration at high temperatures with sufficient residence time leads to complete detoxification of 2,4-D and is the most environmentally acceptable method for 2,4-D disposal. For the decontamination of 2,4-D containers-drums: triple rinse and drain procedure ("triple rinse" means the flushing of containers three times of the normal diluent equal to approximately 10% of the container's capacity and adding the rinse liquid to the spray mixture or disposing of it by the method prescribed for disposing of the pesticide). Small containers should be punched full of holes, crushed and taken to a landfill.
Chemical treatment: Detoxification requires treatment with chloride of lime or sodium carbonate. Rinse containers with a 5% soln of caustic soda. Farms are allowed to destroy if necessary up to 10 kg of the pesticide. Removal of 17% of 2,4-D /(2,4-dichlorophenoxy)acetic acid/ from water is achieved by coagulation and complete water treatment by ozonation; the use of activated charcoal is an effective treatment technique.
Herbicide orange /was incinerated/ by the use of two identical refractory lined furnaces on board the Mt Vulcanus while at sea. The average wall temperature was 1273 deg C and average flame was 1500 deg C. A residence time of 1.0 second was used. Combustion efficiency was > 99.98%. Destruction efficiency was: 2,4-D > 99.9%; 2,4,5-T > 99.9%; Total hydrocarbon 99.982 to 99.992%; Herbicide orange > 99.999%; 2,3,7,8-tetrachlorodibenzo-p-dioxin > 99.93 to > 99.99%; Chlorinated hydrocarbons > 99.999%. /From table/

  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: 2,4-D is readily and rapidly degraded in soil(1). The kinetics of 2,4-D disappearance suggest that microorganisms are responsible(1). The rate will depend on a number of factors including presence of acclimated organisms, nutrient levels, moisture level, temperature, and concentration of 2,4-D(1-3). Typical half-lives range from less than 1 day to more than several weeks under the conditions used(4-8). Degradation with a mixture of microorganisms from activated sludge, soil and sediments lead to half-lives of 1.8-3.1 days under aerobic conditions(4,9). Particular species of microorganisms, of various types, have been isolated and shown to degrade phenoxyacetic acid herbicides in pure culture(1). Degradation of the phenoxyacetic acids proceeds by two main pathways(1). These are via a hydroxyphenoxy acetic acid intermediate or via the corresponding phenol(1). Warm, moist conditions and addition of organic matter stimulate degradation of 2,4-D(7). The breakdown of 2,4-D in two types of soil was investigated under dry and moist conditions and at two different temperatures(7). Generally, 2,4-D disappeared more rapidly from moist soil; after 14 days of a slow rate of disappearance, however, the removal rate from dry, sandy soil increased(7). Numbers of organisms degrading 2,4-D were initially much lower in sandy than in clay loams(7). However, numbers increased rapidly in sandy soils after the addition of the herbicide and, as a result, 2,4-D was eventually degraded more rapidly in sandy than in clay loams(7). In moist conditions, at 25\u00b0C, the half-life of 2,4-D was 7 days or less, whereas in dry conditions, at 35\u00b0C, it could be as long as 250 days(7). These latter conditions are unlikely to apply in most natural conditions where 2,4-D is likely to be used(7). First-order kinetics were observed for the degradation of 2,4-D in sandy loam and muck soils from Malaysia(10). Short half-lives were observed for 2,4-D in aerobic (3.4 days) muck soils(10).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for 2,4-D(SRC), using a log Kow of 2.81(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). The Japanese Chemicals Evaluation and Research Institute has classified 2,4-D as not highly bioaccumulative(4). A depuration half-life of 1.32 days was measured channel catfish (Ictalurus punctatus) exposed to 0.01 ppm 2,4-D over a period of 4 days(5). Rapid depuration was observed for rainbow trout (Salmo gairdneri), channel catfish (Ictalurus punctatus) and bluegill sunfish (Lepomis macrochirus) following 8-hr exposure to 0.3 or 1.0 mg/L C14-labeled 2,4-D butoxyethanol ester(6). Uptake by three seaweeds (Ulva sp, Enteromorpha sp, Rhodymenia sp) at pH 7.8 ranged from 0.01-0.03% of 2,4-D added using 25 ppb C14 ring-labeled 2,4-D(7). Bioaccumulation factors of <10 and 6 were reported for golfen orfe (Leuciscus idus mealnotus) and algae (Chlorella fusca), respectively(8).

12.4 Mobility in soil

Reported experimental 2,4-D (free acid) Koc values are 19.6 (average of 9 soils)(1) to 109.1 (average of 3 soils and range of 72.2-135.7)(2), and 20 to 79(3). According to a classification scheme(4), these Koc values suggest that 2,4-D is expected to have high to very high mobility in soil(SRC). The pKa of 2,4-D is 2.73(5). Anionic 2,4-D adsorption is affected by soil mineralogy (in particular iron and aluminum oxide content), exchangeable aluminum content, and soil phosphate content(6). Adsorption appears to increase with increasing organic content and decreasing pH of soil(7). Average mobility for 14 soils was 0.72 (Rf units), ranging from 0.41 for silty loam to 1.0 for sandy loam(7). In general little runoff occurs with 2,4-D or its amine salts and runoff behavior is the inverse of adsorption behavior(8). Thus, 2,4-D can be desorbed from mineral soils, but not from those containing much organic matter(8). Percolating water appears to be the principal means of movement and diffusion is important only for transport over very small distance(8). Geometric mean concentrations of leached 2,4-D ranged from 0.55-0.87 ug/L at a depth of 0.2 m following applications (rate 0.1-3.3 kg/ha-yr) of the herbicide and irrigation of home garden lawns(9). Upward movement of 2,4-D occurs when the soil surface dries or if rapid evaporation occurs(9). Thus, 2,4-D can be concentrated at the soil surface, where it can be photolyzed, transported by wind either on dust or in vapor form, or leached downwards again(9).
