EXTOXNETPIP - SULFUR Page 3of4 <br /> V r••4 <br /> • Effects on Birds: Sulfur is considered non-toxic to birds (356). The 8-day dietary LC50 for <br /> bobwhite quail is reported to be greater than 5,620 ppm in a study using a 95% sulfur wettable <br /> powder formulation (358). In studies on ecological effects involving bobwhite quail, sulfur has <br /> been shown to be practically non-toxic to the species tested (357). <br /> • Effects on Aquatic Organisms: The 96-hour LC50 values for two fish species, bluegill sunfish <br /> and rainbow trout, are greater than 180 ppm in a study using a 99.5% sulfur dust formulation. The <br /> 48-hour LC50 for daphnia and the 96-hour LC50 for mysid shrimp is reported to be greater than <br /> 5,000 and 736 ppm, respectively, in a study using 90% sulfur (358, 359). In studies on ecological <br /> effects involving two fish species, daphnia, and mysid shrimp, sulfur has been shown to be <br /> practically non-toxic to the species tested (1 , 223, 356, 357). <br /> • Effects on Other Animals (Nontarget species): Sulfur is considered non-toxic to bees (1 , 223 , <br /> 356). In studies on ecological effects involving honeybees, sulfur has been shown to be practically <br /> non-toxic to the species tested. Thus, although there is potential for non-target organisms to be <br /> exposed to sulfur, little hazard to these species is expected to result (357). Two beneficial insect <br /> studies demonstrated that sulfur (98% dust and 92% wettable powder) is low in toxicity to the <br /> honeybee through contact and ingestion (358). <br /> ENVIRONMENTAL FATE ! <br /> • Breakdown of Chemical in Soil and Groundwater: Sulfur is a component of the environment, <br /> and there is a natural cycle of oxidation and reduction reactions which transforms sulfur into both <br /> organic and inorganic products. Sulfur in the form of sulfate constitutes about 0. 1 % of U. S. soils. <br /> Elemental sulfur is slowly converted to sulfate in soil by the action of autotrophic bacteria. <br /> Elemental sulfur leaches in soil as sulfate at a slow rate. About 3-6% of the sulfur (formulation <br /> and purity unspecified) applied at 56 kg/Ha leached through lysimeters of loam soil (soil depth <br /> unspecified) as a result of 40 inches of rain over a six-month period. After two years, 23-29% of <br /> the applied sulfur had leached (359). <br /> • Breakdown of Chemical in Surface Water: No information currently available. <br /> • Breakdown of Chemical in Vegetation: There is slight oxidation of sulfur to the volatile oxide. <br /> Primarily microbial reduction in and on plants; partial incorporation into physiological substances <br /> (1 ). Sulfur may cause plant injury when used at summer temperatures (223). Injury has been <br /> reported on apricots, raspberries, cucurbits and certain other "sulfur-shy" plants (207). <br /> PHYSICAL PROPERTIES AND GUIDELINES <br /> Physical Properties: <br /> • Appearance: yellow crystalline solid <br /> • Chemical Name: Sulfur <br /> • CAS Number: 7704-34-9 (1 , 223) <br /> • Molecular Weight: 32.064 <br /> • Water Solubility: Practically insoluble in water (1 , 242) <br /> • Solubility in Other Solvents: Readily soluble in carbon disulphide. Very slightly soluble in ether, <br /> petroleum ether, toluene, acetone, chloroform, and alcohol; more readily soluble in hot benzene, <br /> acetone, carbon disulfide, carbon tetrachloride, liquid ammonia, and methylene iodide ( 1 , 242, <br /> 354) <br /> • Melting Point: 114.5-115 degrees C (1 , 223, 356); 235 degrees F (354) <br /> • Vapor Pressure: 5 .3 x 10 to the minus 6 mbar at 30.4 degrees C; 8.6 x 10 to the minus 5 mbar at <br /> 59.4 degrees C (1 , 242). 1 mmHg @ 184 degrees C (354). 3.96 x 10 to the minus 6 mmHg at 30.4 <br /> degrees C (356) <br /> .
