• Beschreibung

  Captane is a pesticide belonging to the thiophtalimide group, mainly affecting agricultural workers. As a sensitizer and photosensitizer, it can induce contact urticaria. Its is used as a fungicide and a bacteriostatic agent in cosmetics and toiletries, particularily in shampoos. Cases of contact dermatitis were reoprted in painters, polishers and varnishers.

• Chemische Eigenschaften

  Captan, when pure, is a colorless crystalline solid. The technical grade is a cream to yellow powder with a strong odor. It is commonly dissolved in a “carrier” which may be combustible.

• Verwenden

  Fungicide; bacteriostat in soap.

• Verwenden

  Fungicide used to control diseases on many fruit, ornamental and vegetable crops. Bacteriostat in soaps.

• Verwenden

  Fungicide, often added to pesticide mixtures used to control diseases among fruits, vegetables.

• Verwenden

  Captan is used to control a wide range of fungal diseases on many crops.

• Definition

  ChEBI: A dicarboximide that is 3a,4,7,7a-tetrahydrophthalimide in which the hydrogen attached to the nitrogen is replaced by a trichloromethyl group. A non-systemic fungicide introduced in the 1950s, it is widely used for the control of fungal diseases in fruits, vegetables, and ornamental crops.

• Allgemeine Beschreibung

  Captan is a white solid dissolved in a liquid carrier. Captan is a water emulsifiable liquid. Captan can cause illness by inhalation, skin absorption and/or ingestion. The primary hazard of Captan is that Captan poses a threat to the environment. In case of release immediate steps should be taken to limit its spread to the environment. Since Captan is a liquid Captan can easily penetrate the soil to contaminate groundwater. Captan is used as a fungicide.

• Air & Water Reaktionen

  Slowly hydrolyzed in aqueous neutral and acidic media. Rapidly hydrolyzed in alkaline media. Insoluble in water.

• Reaktivität anzeigen

  Captan decomposes at or near the melting point. Captan is incompatible with strong alkaline and oxidizing materials, sulfur and (sulfur + moisture).

• Hazard

  A questionable carcinogen. A skin irritant. Avoid inhalation of dust or spray mist. Avoid con- tamination of feed and foodstuffs.

• Health Hazard

  Vapor irritates eyes. Ingestion causes depression, lachrymation, labored respiration, diarrhea.

• Brandgefahr

  Special Hazards of Combustion Products: Irritating and toxic gases are produced in a fire; they may include sulfur dioxide, hydrogen chloride, phosgene, and oxides of nitrogen.

• Flammability and Explosibility

  Not classified

• Landwirtschaftliche Anwendung

  Fungicide: Most uses of captan on food crops in the United States have been canceled since 1989. It is still used in apple production, almonds and strawberries. It is often applied to packing and shipping boxes for fruits and vegetables. Captan is rapidly degraded in natural soil by chemical as well as biologic means (estimated half-life, days to weeks). It is also used as a preservative for awnings, draperies and leather, as a root dip and seed treatment. It is also added to paints, wallpaper paste, plastic and leather goods. There are over 320 federally registered pesticide products that contain captan.

• mögliche Exposition

  Captan is a thiophthalimide compound used as an agricultural fungicide for field crops and storage of produce and also as a preservative in cosmetics; an overthe-counter-drug.

• Erste Hilfe

  f this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek med?ical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. If556 Captanthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.

• Environmental Fate

  Biological. In water, captan reacted with the fungicide L-cysteine forming a compound with an absorption maximum of 272 μm which was identified as 2-thiazolidinethione-4- carboxylic acid. In addition, tetrahydrophthalimide also formed (Lukens and Sisler, 1958).
  Soil. The half-lives of captan in soil ranged from 3.5 days (pH 6.4, moisture content 17.5%) to >50 days (pH 6.2, moisture content 1.6%) (Burchfield, 1959). The half-lives of captan in a sandy loam, clay loam and an organic amended soil under non-sterile conditions were 10–354, 3.4–587 and 7.0–213 days, respectively, while under sterile conditions the half-lives were 9.4–373, 2.8–303 and 4.3–191 days, respectively (Schoen and Winterlin, 1987).
  Chemical/Physical. Captan undergoes hydrolysis under neutral or alkaline conditions yielding 4-cyclohexene-1,2-dicarboximide, carbon dioxide, hydrogen chloride and sulfur (Wolfe et al., 1976a). The estimated hydrolysis half-life of captan in a phosphate buffer solution at pH 7.07 and 28–29°C is 2.96 hours. Between the pH range 2 to 6, the estimated hydrolysis half-life is 10.70 hours (Wolfe et al., 1976a). Worthing and Hance (1991)reported hydrolysis half-lives of 8.3–32.4 hours and <2 minutes at pH values 7 and 10, respectively.
  Decomposes at or near the melting point (Hartley and Kidd, 1987).

• Stoffwechselwegen

  Captan contains an unstable trichloromethylthio (sulfenyl) moiety that has been shown to undergo rapid hydrolytic and metabolic degradation to tetrahydrophthalimide (2).
  Studies of the decomposition of [³⁵S]captanw ith conidia of Neurospora crassa (Richmond and Somers, 1968) showed that the trichloromethythio moiety can be transferred to the sulfur atoms of thiols such as cysteine and glutathione (Richmond and Somers, 1966). Thus, in the presence of thiols such as glutathione, captan is cleaved at the N-S bond to form thiophosgene (3) and other gaseous products such as hydrogen sulfide, hydrogen chloride and carbonyl sulfide (see Scheme 2). Thiophosgene is rapidly hydrolysed by water. The trichlormethythio group and thiophosgene are believed to be intermediates in the formation of thiazolidine-2- thione-4-carboxylic acid (4) which is an addition product with cysteine. A thiazolidine derivative of glutathione is also formed (5). Biotransformation of captan in mammals generates primarily thiophosgene (3) and tetrahydrophthalimide (2). Tetrahydrophthalimide (2) and various of its hydroxylated derivatives are excreted in the urine. The thiophosgeneglutathione adduct (5) subsequently degrades and is eventually excreted in the urine as 2-thiazolidinethione-4-carboxylic acid (4).

• Toxicity evaluation

  The half-life of captan is 1–10 days in a soil environment, and hours to days in water depending on acidities and temperatures. Captan is not mobile in soil but can significantly evaporate from the soil surface. It is quickly degraded in neutral water.

• Inkompatibilitäten

  Incompatible with tetraethyl pyrophosphate, parathion. Keep away from strong alkaline materials(e.g., hydrated lime) as captan may become unstable. May react with water releasing hydrogen chloride gas. Corrosive to metals in the presence of moisture.

• Waste disposal

  Captan decomposes fairly readily in alkaline media (pH ＞8). It is hydrolytically stable at neutral or acid pH but decomposes when heated alone at its freezing/melting point. Alkaline hydrolysis is recommended
