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. 2-methyl-4-chlorophenoxyacetic acid 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. Case No: 0017Pesticide type: HerbicideRegistration Standard Date: 09/12/89Case Status: OPP is reviewing data from the pesticide's producers regarding its human health and/or environmental effects, or OPP is determining the pesticide's eligibility for reregistration and developing the Reregistration Eligibility Decision (RED) document.Active ingredient (AI): 2-methyl-4-chlorophenoxyacetic acidData Call-in (DCI) Date(s): 05/12/93, 04/06/94, 03/03/95, 10/13/95AI Status: The producers of the pesticide has made commitments to conduct the studies and pay the fees required for reregistration, and are meeting those commitments in a timely manner. |
| Chemical Dangers | Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride and phosgene. The substance is a weak acid. Attacks many metals in the presence of water. |
| Packaging and Labelling | Do not transport with food and feedstuffs. |

| Brandbekämpfung | In case of fire in the surroundings, use appropriate extinguishing media. |
| Erste-Hilfe-Maßnahmen | Fresh air, rest. Refer for medical attention.Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.Rinse mouth. Give one or two glasses of water to drink. Refer immediately for medical attention. |
| Sichere Lagerung | Provision to contain effluent from fire extinguishing. Separated from strong bases and food and feedstuffs. Store in an area without drain or sewer access. Cool. |
| Lagerbedingungen | Keep in well-ventilated area.Do not transport or store near fertilizers, seeds, insecticides, or fungicides. |
| Entsorgungsverfahren | 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.Incineration: Liquids should be atomized into an incinerator equipped with an appropriate effluent gas cleaning device, and combustion maybe improved by mixing with a more flammable solvent (acetone or benzene). Solids should be combined with paper or other flammable material. An alternate procedure is to dissolve the solid in a flammable solvent and spray the solutions into the fire chamber. |
| Verschüttetes entsorgen | Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. |
| Preventive Measures | 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. |
| Eye Prevention | Wear safety goggles or eye protection in combination with breathing protection if powder. |
| Inhalation Risk | Evaporation at 20 °C is negligiblea harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. |
| Skin Prevention | Protective gloves. Protective clothing. |
| Exposure Prevention | PREVENT DISPERSION OF DUST! |

| Körperbelastung | 2-Methyl-4-chlorophenoxyacetic acid residues were measured in 18 urine samples collected from workers who had been spray applying the herbicide less than 24 hr previous(1)concns of 10-50 ppb were found in 8 samples, concns of 50-150 ppb were found in 5 samples, and concns of 150-500 ppb were found in 5 samples(1). In another monitoring study of farmers and professional spraymen, median urine concns of 0.31-1.7 ug/ml were detected(2).IN A SUICIDE, SPECIMENS TAKEN AT AUTOPSY CONTAINED THE FOLLOWING CONCENTRATIONS OF MCPA: BLOOD, 230 PPMLIVER, 146 PPMHEART, 154 PPM& BRAIN, 32.8 PPM. IN ANOTHER CASE, THE CONCENTRATIONS IN AUTOPSY SPECIMENS OF BLOOD & URINE WERE 180 & 800 PPM, RESPECTIVELY. |
| Treatment | Treatment may include washing any areas of contact, GI decontamination if swallowed, administering an IV and forced alkaline diuresis. (L346) |
| Wechselwirkungen | Probenecid increased the acute toxicity of chlorophenoxyacetic acids (2,4-D, 2,4,5-T and MCPA) in rats. Probenecid increased the brain to plasma ratios of all the three (14)C labelled chlorophenoxyacetic acids. The increase was due only partly to the displacement of chlorophenoxyacids from their binding sites in rat plasma proteins by probenecid. Probenecid did not change significantly the intracerebral distribution pattern of (14)C labelled chlorophenoxyacetic acids. |

| Gesundheitliche Auswirkungen | Exposure to large amounts of CDDs causes chloracne, a severe skin disease with acne-like lesions that occur mainly on the face and upper body. CDDs may also cause liver damage and induce long-term alterations in glucose metabolism and subtle changes in hormonal levels. In addition, studies have shown that CDDs may disrupt the endocrine system and weaken the immune system, as well as cause reproductive damage and birth defects, central and peripheral nervous system pathology, thyroid disorders, endometriosis, and diabetes. 2,3,7,8-Tetrachlorodibenzo-p-dioxin is also a known human carcinogen.

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), a Koc value ranging from the 50 to 62 (2), indicates that MCPA is expected to have high mobility in soil(SRC). Volatilization of MCPA from moist soil surfaces is not expected to be an important fate process(SRC) based on its Henry's Law constant of 4.80X10-10 atm-cu/mole(3). MCPA is not expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 5.90X10-6 mm Hg(4). The primary degradation process for MCPA in soil is biodegradation(5). A literature review of available laboratory persistence studies of MCPA in soil found soil half-lives ranging from <7 to 41 days with an average of about 2-3 weeks(6). MCPA is susceptible to photodegradation in sunlight(5,7)however, photodegradation at the soil surface is not considered a major degradation pathway since it is applied post-emergence to growing crops, and residues reaching the soil will be protected from sunlight by the crop canopy(5). Under field studies, the resultant average persistence of MCPA at recommended application rates is up to 1 month in moist conditions and up to 6 months under drier climates(8).AQUATIC FATE: Based on a classification scheme(1), a Koc value ranging from 50 to 62(2), indicates that MCPA is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon its Henry's Law constant of 4.80X10-10 atm-cu m/mole(4). According to a classification scheme(5), a BCF of 1(6), suggests the potential for bioconcentration in aquatic organisms is low. Based on degradation studies, it appears that MCPA will biodegrade in water but at a slower rate than in soil. In flooded sediment, the complete degradation of MCPA took 96 wks, but only 48 wks in moist soilthe ratio of relative persistence in moist soil vs. flooded sediment was determined to be 1:2.3(7). The direct photolysis half-life of MCPA in water (at surface conditions under summer sunlight) is about 19-20 days(8).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), MCPA, which has a vapor pressure of 5.90X10-6 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase MCPA 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 30 hours(SRC), calculated from its rate constant of 1.3X10-11 cu cm/molecule-sec at 25 °C(SRC), determined using a structure estimation method(3). Particulate-phase MCPA may be removed from the air by wet and dry deposition(SRC). Aerial drift from herbicidal spraying operations can transport MCPA to nearby ponds and streams(4). A multi-year study of MCPA in surface water of a small prairie watershed concluded that the aqueous concns of MCPA were related to elevated precipitation and air levels rather than to runoff losses(5). MCPA may undergo direct photolysis since it is photochemically reactive in water(6). Exposure of aqueous solutions of MCPA in distilled water to Oct sunlight in Davis, CA resulted in a 14% decomposition of MCPA after 245 hr of exposure(7). |
| Lebensmitteluntersuchungswerte | No 2-methyl-4-chlorophenoxyacetic acid (MCPA) residues were detected in any food composites collected from July 1, 1969 to June 30, 1976 as part of the FDA's (Food and Drug Administration) Total Diet Study (market basket survey of ready-to-eat US foods)(1). In earlier Total Diet Study analyses (June 1964 to Apr 1969), MCPA was detected in 11 of 1236 food composite samples at levels ranging from a trace to 0.40 ppm(2-5). |

| Toxizitätsübersicht | CDDs cause their toxic effects by binding to the aryl hydrocarbon receptor and subsequently altering the trascription of certain genes. The affinity for the Ah receptor depends on the structure of the specific CDD. The change in gene expression may result from the direct interaction of the Ah receptor and its heterodimer-forming partner, the aryl hydrocarbon receptor nuclear translocator, with gene regulatory elements or the initiation of a phosphorylation/dephosphorylation cascade that subsequently activates other transcription factors. The affected genes include several oncogenes, growth factors, receptors, hormones, and drug-metabolizing enzymes. The change in transcription/translation of these genes is believed to be the cause of most of the toxic effects of CDDs. This includes 2,3,7,8-tetrachlorodibenzo-p-dioxin's carcinogenicity is thought to be the result of its ability to alter the capacity of both exogenous and endogenous substances to damage the DNA by inducing CYP1A1- and CYP1A2-dependent drug-metabolizing enzymes.
