The solution is typically yellow to dark green and has a rotten-egg odor due to the Hydrogen Sulfide (H2S) content. The product strength ranges from 20% to 45% by weight and weighs 9 to 11 pounds per gallon (specific gravity from 1.13 to 1.30 g/cm3). Solutions of NaHS are considered stable in normal transportation. The vapor space over NaHS solutions contains highly toxic Hydrogen Sulfide gas. The Hydrogen Sulfide gas is colorless and it is heavier than air. It will remain close to the ground and collect in low lying areas. The amount of Hydrogen Sulfide gas evolved from NaHS solutions is noticeably increased when the pH of the solution is below the pH of 10.2. This happens when the solution comes into contact with acidic materials or other materials that have a pH lower than 10.2. Dilution of the material will also create a minimal amount of Hydrogen Sulfide gas due to the lower pH of water coming in contact with the solution.

  • Sodium Hydrosulfide (Nahs) Recommended Procedures for Truck Unloading
    Sodium Hydrosulfide (NaHS) Recommended Procedures for Truck Unloading TDC, LLC 1916 Farmerville Hwy. Ruston LA 71270 The following presentation was designed to provide specific information on unloading trucks containing Sodium Hydrosulfide (NaHS). This presentation has been developed as a guide only. THINK SAFETY AT ALL TIMES! STAY ON TOP OF SAFE HANDLING PROCEDURES Safety is Everyone’s Business Training Requirements Personnel handling hazardous chemicals should be trained in accordance with the applicable federal and state requirements These training requirements include, but may not be limited to: • Hazard Communications - 29 CFR 1910.1200 • Personal Protective Equipment - 29 CFR 1910.132 • Respiratory Protection - 29 CFR 1910.134 • Occupational Noise Exposure - 29 CFR 1910.95 • Hazmat - 49 CFR 172.700 Shipping Requirements Sodium Hydrosulfide (NaHS) is classified as a corrosive and toxic liquid. The Proper Shipping Description is: UN2922 Corrosive liquids, toxic, n.o.s., 8(6.1), PG II (sodium hydrosulfide solution) Bulk shipments are placarded “Corrosive”. KNOW THE PRODUCT! Read the MSDS MSDS Review ¾ Sodium Hydrosulfide (NaHS) is very alkaline (pH 11.5- 12.5) and very corrosive to the skin. ¾ Solution is typically yellow to dark green with a strong hydrogen sulfide (rotten egg) odor. ¾ Solutions are 20% to 45% strength and weigh 9.6 – 10.9 ppg. ¾ The vapor space over NaHS solutions contains highly toxic hydrogen sulfide (H2S). This gas is colorless and heavier than air. The level of H2S above the solution is increased by solution contact with acidic materials, heating the solution and dilution, which lowers the pH of the solution. NaHS is manufactured by reacting Hydrogen Sulfide Gas (H2S) with Sodium Hydroxide (Caustic Soda) (NaOH).

  • Sodium Hydrogen Sulfide
    Product Safety Summary Sodium Hydrogen Sulfide, Solid (70-72% with Crystallization Waters < 25%) CAS No. 16721-80-5 This Product Safety Summary is intended to provide a general overview of the chemical substance. The information on the summary is basic information and is not intended to provide emergency response information, medical information or treatment information. The summary should not be used to provide in-depth safety and health information. In-depth safety and health information can be found on the Safety Data Sheet (SDS) for the chemical substance. Names Sodium hydrogen sulfide (sulphide) Sodium hydrosulfide (hydrosulphide) Sodium mercaptan Sodium sulfhydrate Sodium bisulfide Sodium mercaptide Product Overview Solvay Fluorides, LLC does not sell sodium hydrogen sulfide directly to consumers. Consumers are unlikely to be exposed to sodium hydrogen sulfide in any of the consumer product applications listed below and only where the sodium hydrogen sulfide is not transformed or reacted. Sodium hydrogen sulfide is a yellow, solid flake with a sulfurous (rotten egg) smell. It is used in water treatment, the pulp and paper industry, and in leather processing as a tanning agent or hair remover (from hides). Sodium hydrogen sulfide may be used in the making of colors and dyes. It can also be used in the manufacture of other chemicals, metals or in ore processing (mining) and in waste water, soil and process sludge treatment. Exposure to sodium hydrogen sulfide can cause severe irritation to the skin, eyes, and respiratory tract. Sodium hydrogen sulfide may cause sensitization (develop an allergic reaction). Breathing sodium hydrogen sulfide dusts may aggravate asthma or other pulmonary (breathing) diseases and may cause headaches, dizziness, nausea and vomiting.

These observations have generated interest in harnessing H2S as a potential therapeutic agent to treat disease states and chronic conditions associated with H2S-based signaling. A mechanistic analysis of these physiological processes reveals the prevalence of H2S and other reactive sulfur species including sulfane sulfur and persulfides. To better understand the biological properties of these reactive sulfur species, chemical tools which provide methods of generating these fleeting species under controlled reaction conditions are needed.

Abstract: Plant secondary metabolites (SMs) play important roles in plant survival and in creating ecological connections between other species. In addition to providing a variety of valuable natural products, secondary metabolites help protect plants against pathogenic attacks and environmental stresses. Given their sessile nature, plants must protect themselves from such situations through ac- cumulation of these bioactive compounds. Indeed, secondary metabolites act as herbivore deterrents, barriers against pathogen invasion, and mitigators of oxidative stress. The accumulation of SMs Citation: Jan, R.; Asaf, S.; Numan, are highly dependent on environmental factors such as light, temperature, soil water, soil fertility, M.; Lubna; Kim, K.-M.
