| Chemical Properties | Endosulfan is a chlorinated cyclodiene insecticide. The pure product is a colorless crystalline solid. The technical product is a light to dark brown waxy solid. It has arotten egg or sulfur odor. |
| Physical properties | Colorless to brown, nonflammable solid or crystals with a mild odor similar to terpene or sulfurdioxide. |
| Uses | β-Endosulfan may be used as an analytical pesticide reference standard for the determination of the analyte in water samples, virgin olive oil, aged contaminated Ethiopian soils and human fluids by various chromatography techniques. |
| Uses | Insecticide for vegetable crops. |
| General Description | Brown crystals. Melting point 208-210°C. Used as an insecticide. |
| Air & Water Reactions | Insoluble in water. Reacts slowly with water to generate sulfur dioxide. |
| Reactivity Profile | BETA-ENDOSULFAN is a sulfite ester of a chlorinated cyclic diol. Decomposed rapidly by alkali to generate sulfur dioxide. Decomposed by acid. Incompatible with strong oxidizing and reducing agents. may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides. |
| Health Hazard | ACUTE/CHRONIC HAZARDS: Highly toxic by ingestion, inhalation, and skin absorption. |
| Fire Hazard | Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways. |
| Environmental Fate | Soil. Metabolites of endosulfan identified in soils included endosulfandiol, endosulfanhydroxyether, endosulfan lactone and endosulfan sulfate (Martens, 1977; Dreher andPodratzki, 1988). These compounds, including endosulfan ether, were also reported asmetabolites identified in aquatic systems (Day, 1991). In aerobic soils, b-endosulfan isconverted to the corresponding alcohol and ether (Perscheid et al., 1973). Endosulfansulfate was the major biodegradation product in soils under aerobic, anaerobic and floodedconditions (Martens, 1977). In flooded soils, endolactone was detected only once whereasendodiol and endohydroxy ether were identified in all soils under these conditions. Underanaerobic conditions, endodiol formed in low amounts in two soils (Martens, 1977).Indigenous microorganisms obtained from a sandy loam degraded b-endosulfan toendosulfan diol. This diol was converted to endosulfan a-hydroxy ether and trace amountsof endosulfan ether and both were degraded to endosulfan lactone (Miles and Moy, 1979). Plant. In addition, endosulfan sulfate was formed when endosulfan was translocatedfrom the leaves to roots in both bean and sugar beet plants (Beard and Ware, 1969). Intobacco leaves, b-endosulfan hydrolyzed into endosulfandiol (Chopra and Mahfouz, 1977).Stewart and Cairns (1974) reported the metabolite endosulfan sulfate was identified inpotato peels and pulp at concentrations of 0.3 and 0.03 ppm, respectively. They alsoreported that the half-life for the oxidative conversion of b-endosulfan to endosulfan sulfatewas 800 days. In carnation plants, the half-lives of b-endosulfan stored under four different conditions,non-washed and exposed to open air, washed and exposed to open air, non-washedand placed in an enclosed container and under greenhouse conditions were 23.40, 12.64,37.42 and 7.62 days, respectively (Ceron et al., 1995). Surface Water. Endosulfan sulfate was also identified as a metabolite in a survey of11 agricultural watersheds located in southern Ontario, Canada (Frank et al., 1982). Whenendosulfan (a- and b- isomers, 10 mg/L) was added to Little Miami River water, sealedand exposed to sunlight and UV light for 1 week, a degradation yield of 70% was observed.After two and four weeks, 95% and 100% of the applied amount degraded. The majordegradation product was identified as endosulfan alcohol by IR spectrometry (Eichelbergerand Lichtenberg, 1971). Photolytic. Thin films of endosulfan on glass and irradiated by UV light (l >300 nm)produced endosulfan diol with minor amounts of endosulfan ether, lactone, a-hydroxyetherand other unidentified compounds (Archer et al., 1972). Gaseous b-endosulfan subjectedto UV light (l >300 nm) produced endosulfan ether, endosulfan diol, endosulfan sulfate,endosulfan lactone, a-endosulfan and a dechlorinated ether (Schumacher et al., 1974).Irradiation of b-endosulfan in n-hexane by UV light produced the photoisomer a-endosulfan(Putnam et al., 1975). When an aqueous solution containing endosulfan was photooxidizedby UV light at 90–95°C, 25, 50 and 75% degraded to carbon dioxide after 5.0, 9.5and 31.0 hours, respectively (Knoevenagel and Himmelreich, 1976). Chemical/Physical. Endosulfan detected in Little Miami River, OH was readily hydrolyzedto a compound tentatively identified as endosulfan diol (Eichelberger and Lichtenberg,1971). Sulfuric acid is also an end product of hydrolysis (Kollig, 1993). The hydrolysishalf-lives at pH values (temperature) of 3.32 (87.0°C), 6.89 (68.0°C) and 8.69 (38.0°C)were calculated to be 2.7, 0.07 and 0.04 days, respectively (Ellington et al., 1988). Greveand Wit (1971) reported the hydrolysis half-lives of b-endosulfan at 20°C and pH valuesof 7 and 5.5 were 37 and 187 days, respectively. |

| Waste Disposal | A recommended method fordisposal is burial 18 in deep in noncropland, away fromwater supplies, but bags can be burned. Large quantitiesshould be incinerated at high temperature in a unit witheffluent gas scrubbing. Consult with environmental regulatory agencies for guidance on acceptable disposal practices.Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage,transportation, treatment, and waste disposal. In accordancewith 40CFR165, follow recommendations for the disposalof pesticides and pesticide containers. Must be disposedproperly by following package label directions or by contacting your local or federal environmental control agency,or by contacting your regional EPA office. |
