| Entsorgungsverfahren | SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations.The following scheme is proposed for treating effluents from the production of chloropicrin. These wastewaters contain Ca(ClO)2 approx 2000 mg/l, chloropicrin approx 80 mg/L, and picric acid approx 80 mg/L. The Ca(ClO)2 is first removed by reduction with FeSO4 at 90-95 deg, and pH of 11-11.5. Complete removal is achieved in 3 hours. The nitro compounds are then reduced to MeNH2 and triaminophenol by heating the effluent from the first stage with FeSO4 and Fe turnings at 90-95 deg. Reduction of the nitro compounds is approx 81% complete, the residue containing compounds are not readily reduced. The MeNH2 vapor is oxidized to MeOH in a reactor containing a soln of NaNO2 and HCl at 5-6 deg. The reaction time is 2-2.5 hours. The MeOH and triaminophenol are then oxidized with Ca(ClO)2, and the final treated effluent is clearified before discharge.Chloropicrin reacts readily with alcoholic sodium sulfite soln to produce methanetrisulfonic acid (which is relatively non volatile and less harmful). This reaction has been recommended for treating spills and cleaning equipment. Although not specifically suggested as a decontamination procedure, the rapid reaction of chloropicrin with ammonia to produce guanidine (LD50= 500) could be used for detoxication. The Manufacturing Chemists Association suggest two procedures for disposal of chloropicrin: 1) Pour or sift over soda ash. Mix and wash slowly into large tank. 2) Adsorb on vermiculite. Mix and shovel into paper boxes. Drop into incinerator with afterburner and scrubber. Recommendable methods: Neutralization, & incineration. |

| Umweltverhalten | TERRESTRIAL FATE: Based on a classification scheme(1), a Koc value of 81(2) indicates that chloropicrin is expected to have high mobility in soil(SRC). Volatilization of chloropicrin from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 2.05X10-3 atm-cu m/mole(2). Chloropicrin is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 23.8 mm Hg(3). Half-lives in soil ranging from 0.2 to 4.5 days at 20 °C(4) suggests that biodegradation is an important environmental fate process in soil(SRC).AQUATIC FATE: Based on a classification scheme(1), a Koc value of 81(SRC), determined from a structure estimation method(2), indicates that chloropicrin is not expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon a Henry's Law constant of 2.05X10-3 atm-cu m/mole(2). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 4 hours and 5 days, respectively(SRC). According to a classification scheme(4), an estimated BCF of 8(SRC), from its log Kow of 2.09(5) and a regression-derived equation(6), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Chloropicrin photohydrolyzes rapidly in water when exposed to light below 300 nm producing CO2, chloride and nitrate in the presence of airits half-life in sunlight is about 3 days(7). However, under ambient room light chloropicrin is stable to photodegradation(7). The photooxidation of vapor-phase chloropicrin to form phosgene has also been observed in the field(8). A half-life of 0.5 days in activated sludge(9) suggests that biodegradation may be an important environmental fate process in water(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), chloropicrin, which has a vapor pressure of 24 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase chloropicrin 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 120 days(SRC), calculated from its rate constant of 1.3X10-13 cu cm/molecule-sec at 25 °C(SRC), that was derived using a structure estimation method(3). Chloropicrin absorbs UV light in the 280 to 390 nm range(4) and therefore may be susceptible to direct photolysis(SRC). |
| Lebensmitteluntersuchungswerte | An FDA survey of over 500 foods for the presence of fumigants resulted in 2 findings of chloropicrin at an average concn of 17 ppb(1).

| Effluent Concentrations | In a comprehensive survey of wastewater from 4,000 industrial and publicly owned treatment works (POTWs) sponsored by the Effluent Guidelines Division of the U.S. EPA, chloropicrin was identified in discharges of the following industrial category (positive occurrences, median concentration in ppb): organics and plastics (177.8), pharmaceuticals (17.5), electroplating (140.5)(1). Chloropicrin has been identified as a volatile formed in the bleaching of hardwood (birch) and softwood pulp (pine, spruce) with carbon dioxide(2).Chloropicrin is formed in the chlorination of natural water containing humic substances in the presence of nitrites(1,5) which would explain its presence in drinking waters(SRC). The use of ozone in water treatment to reduce trihalomethanes (especially ozonation followed by chloramination), appears to increase the amount of chloropicrin in the treated water. In two utilities studied, the concn of chloropicrin in the treated water was 0.073 and 0.25 ppb using chlorine alone and 0.49 and 0.57 ppb when both ozone and chlorine treatment was used(3). In another study chlorination of water from mesotrophic and eutrophic lakes produced 0.4 and 2 ppb of chloropicrinwith preozonation these levels increased to about 2 and 6 ppb, respectively(4). Chloropicrin may be formed during the chlorination of industrial waste water. Studies show that the chlorination of nonnitrogenous organic compounds (0.1 mmol/L) in the presence of nitrites (0.1 mmol/L) can lead to chloropicrin formation(1). Among these, phenolic compounds and 2- and 3-hydroxyphenol, in particular, give the highest production rates. Choropicrin is also readily formed from nitromethane during chlorination(2). |
| Medical Surveillance | Initial Medical Examination: A complete history and physical examination: The purpose is to detect pre-existing conditions that might place the exposed employee at increased risk, and to establish a baseline for future health monitoring. Examination of the respiratory system should be stressed. The skin should be examined for evidence of chronic disorders. ... Persons with impaired pulmonary function may be at increased risk from exposure. ... Medical examinations should be repeated on an annual basis.Laboratory testing should be dictated by clinical presentation and condition of the patient. The provider may consider addition of creatine kinase (CK) and blood gas with co-oximetry. Chloropicrin may be detected by gas chromatography/mass spectrometry (GC/MS). |

CLASSIFICATION: Unclassified.Based on a review of the chloropicrin data and public comments on the Agency's assessments for the active ingredient chloropicrin, the Agency has sufficient information on the human health and ecological effects as well as the benefits of chloropicrin to make a decision as part of the reregistration process under FIFRA. The Agency has determined that most of the supported uses of chloropicrin will not pose unreasonable risks or adverse effects to humans or the environment provided that the risk mitigation measures and label changes outlined in this RED are implemented. The Agency does not have adequate data to evaluate the risks associated with untarped chloropicrin drip applications that are buried a minimum of 5 inches. The CMTF has just submitted a study, and provided the study is acceptable and the Agency can determine appropriate risk mitigation, this use will be eligible for reregistration. Based on its evaluation of chloropicrin, the Agency has determined that chloropicrin products, unless labeled and used as specified in this document, would present risks inconsistent with FIFRA. Accordingly, should a registrant fail to implement any of the risk mitigation measures identified in this document, the Agency may take regulatory action to address the risk concerns from the use of chloropicrin. If all changes outlined in this document are incorporated into the product labels, then current risks for chloropicrin will be adequately mitigated for the purposes of this determination under FIFRA.As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. 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. Chloropicrin 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.

Beschreibung
Chloropicrin is a colorless to faint-yellow oily liquid with an intensely irritating and sharp odor with characteristics of tear gas. Some common trade names of products containing chloropicrin include Dolochlor, Aquinite, Nemax, Pic-Chlor, Timberfume, Profume A, Tri-Clor, and Microlysin. It has a molecular weight of 164.38, water solubility of 2000 mg l1 at 25°C, and melting and boiling points of 64 and 112°C, respectively. Chloropicrin is nonflammable and has a vapor density of 5.7 compared to the vapor density of one assigned to air. Heating above 234 F results in explosive decomposition of chloropicrin, leading to the release of toxic gases, including nitrogen oxides, phosgene, nitrosyl chloride, chlorine, and carbon monoxide. Chloropicrin is a widely used fungicide that is primarily used for preplant soil fumigation. Chloropicrin is used to fumigate stored grain and to treat soil against fungi, insects, and nematodes either as a stand-alone treatment or in combination with other fumigants like methyl bromide and sulfuryl fluoride for enhanced potency. Chloropicrin is also used to prevent internal decay of wood poles and timber caused by fungi and insects.
