Description

Sulfallate is an amber liquid.


Sulfallate is an amber to dark amber liquid. (NTP, 1992)


Sulfallate is an amber to dark amber liquid. (NTP, 1992)|Sulfallate is a thiocarbonyl compound.|Sulfallate is a synthetic, amber oil that is slightly soluble in water and soluble in most organic solvents. Sulfallate products are no longer used in the United States. Therefore, the potential for human exposure is low. When heated to decomposition, sulfallate emits toxic fumes of hydrochloric acid, nitrogen, and sulfur oxides. It is reasonably anticipated to be a human carcinogen. (NCI05)

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity 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 quality; potential migration in soil or water; effects on animal and plant life; and conformance with environmental and public health regulations.|SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a permitted wastewater treatment facility is acceptable only after review by the governing authority and assurance that "pass through" violations will not occur. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must be evaluated in accordance with EPA 40 CFR Part 261, specifically Subpart B, in order to determine the appropriate local, state and federal requirements for disposal.|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.|Hydrolysis: Sulfallate is hydrolyzed very slowly in either very weak acid, pH 5, or very weak base, pH 8. It is hydrolyzed rapidly in boiling caustic and is completely decomposed by strong oxidizing agents. Recommendable method: Incineration. Peer-review: Large amt should be incinerated in a unit with effluent gas scrubbing.

Sulfallate is not known to occur as a natural product.

Sulfallate's former US production may have resulted in its release to the environment through various waste streams; its former use as a herbicide(1) resulted in its direct release to the environment(SRC).

TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 2000(SRC), determined from a structure estimation method(2), indicates that sulfallate is expected to have moderate mobility in soil(SRC). Volatilization of sulfallate from moist soil surfaces is expected to be an important fate process(SRC) based upon an estimated Henry's Law constant of 6.5X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 2.2X10-3 mm Hg(3), and water solubility, 100 mg/L(4). However, adsorption to soil is expected to attenuate volatilization(SRC). Sulfallate is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(3). It persists in soil for 21 to 42 days(5).|TERRESTRIAL FATE: Resultant average persistence at recommended rates: generally 3-6 weeks, on sandy soils with heavy rainfall, CDEC will persist 3-4 weeks, and 5-6 weeks on loams or clay soils with moderate precipitation|TERRESTRIAL FATE: At commercially recommended rates of 4 lb/gal, the average persistence of sulfallate in soil is 3 to 6 weeks.|AQUATIC FATE: Based on a classification scheme(1), an estimated Koc value of 2000(SRC), determined from a structure estimation method(2), indicates that sulfallate is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is expected(3) based upon an estimated Henry's Law constant of 6.7X10-6 atm-cu m/mole(SRC), derived from its vapor pressure, 2.2X10-3 mm Hg(4), and water solubility, 100 mg/L(5). Using this Henry's Law constant and an estimation method(3), volatilization half-lives for a model river and model lake are 9 and 67 days, respectively(SRC). According to a classification scheme(6), an estimated BCF of 60(SRC), from an estimated log Kow of 3.15(7) and a regression-derived equation(2), suggests the potential for bioconcentration in aquatic organisms is moderate(SRC). Biodegradation data in water were not available(SRC, 2012).|ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), sulfallate, which has a vapor pressure of 2.2X10-3 mm Hg at 20 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase sulfallate 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 1.2 hours(SRC), calculated from its rate constant of 1.0X10-10 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Sulfallate absorbs light at wavelengths >290 nm(4), and therefore may be susceptible to direct photolysis by sunlight(SRC).

The rate constant for the vapor-phase reaction of sulfallate with photochemically-produced hydroxyl radicals has been estimated as 1.0X10-10 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 1.2 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). The rate constant for the vapor-phase reaction of sulfallate with ozone has been estimated as 1.6X10-18 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(1). This corresponds to an atmospheric half-life of about 7 days at an atmospheric concentration of 7X10+11 ozone molecules per cu cm(2). Sulfallate is hydrolyzed by alkali, with half-lives of 57 days at pH 5 and 30 days at pH 8 being reported(3). Sulfallate absorbs light at wavelengths >290 nm(4), and therefore may be susceptible to direct photolysis by sunlight; the kinetics of this potential reaction are unknown(SRC). Sulfallate persists in soil for 21 to 42 days(3).

An estimated BCF of 60 was calculated in fish for sulfallate(SRC), using an estimated log Kow of 3.15(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of sulfallate can be estimated to be 2000(SRC). According to a classification scheme(2), this estimated Koc value suggests that sulfallate is expected to have low mobility in soil.

The Henry's Law constant for sulfallate is estimated as 6.5X10-6 atm-cu m/mole(SRC) derived from its vapor pressure, 2.2X10-3 mm Hg(1), and water solubility, 100 mg/L(2). This Henry's Law constant indicates that sulfallate is expected to volatilize from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 9 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 67 days(SRC). Sulfallate's estimated Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Sulfallate is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure(1).

SURFACE WATER: Sulfallate was detected in surface water from the Comunitat Valenciana, Spain at a concentration of 2.247 ug/mL(1).

Sulfallate was identified, not quantified, in vegetables during the 1978-1982 pesticide monitoring program by the US FDA(1) and in the 1988-1989 monitoring program(2). Sulfallate was identified, not quantified in domestic and imported tomatoes(3).

A potential for exposure exists during the manufacture and application of the herbicide. Agricultural workers have the greatest risk of sulfallate exposure, and rural residents of agricultural communities may be exposed to airborne residues of sulfallate after spraying operations. ... The general population may be exposed through ingestion of residues in food crops.|Occupational exposure and general population exposure should be low or non-existent since sulfallate is no longer produced or used in the US (2012). The general population may have been exposed to sulfallate via ingestion of vegetables grown in fields treated with sulfallate to control certain annual grasses and broadleaf weeds. (SRC)

The quantitative relationships indicate that the thiocarbamates yield chloroacroleins on metabolic activation with the mixed function oxidase system alone, while the intermediate S-oxidation products were detoxified on diversion to chloroallylthiols when the glutathione/glutathione-S-transferase system was also present. The major mouse microsomal mixed function oxidase metabolites of three cmpd were identified by HPLC cochromatography as the corresponding sulfoxides. It was concluded that the formation of mutagenic chloroacroleins involves primarily sulfoxidation of diallate followed by sigmatropic rearrangement-1,2-elimination reactions and S-methylene hydroxylation of triallate and sulfallate and then decomposition of their alpha-hydroxy intermediates. Competing glutathione-S-transferase catalyzed conjugations with glutathione divert the sulfoxidized intermediates from activation involving chloroacrolein formation to detoxification on chloroallylthiol liberation.

SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin and eyes. It can cause erythema. Other symptoms may include headache, weakness, fatigue, central nervous system depression, peripheral neuropathy, toxic psychosis, toxic hepatitis, burns of the mucous membranes and reproductive effects. Exposure to this type of compound may cause impotence. ACUTE/CHRONIC HAZARDS: This compound is moderately toxic by ingestion and skin contact. When heated to decomposition it emits very toxic fumes of chlorine, oxides of nitrogen and oxides of sulfur. (NTP, 1992)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital. OTHER: Since this chemical is a known or suspected carcinogen you should contact a physician for advice regarding the possible long term health effects and potential recommendation for medical monitoring. Recommendations from the physician will depend upon the specific compound, its chemical, physical and toxicity properties, the exposure level, length of exposure, and the route of exposure.
