VLISEDIS , ABSTRACT A method for the determination of sulfate and sulfide sulfur that occur together in rocks or minerals is presented. All the sulfate sulfur is converted to barium sulfate in an inert atmosphere to prevent oxidation of any sulfide sulfur. Cadmium chloride is added to precipitate any sulfide ion that may be liberated. The sulfate sulfur is then measured indirectly by the determination of the barium and is therefore unaffected by any. subsequent oxidation of the sulfide sulfur.

Sulfur and Tennessee Row Crops
W 435 SULFUR AND TENNESSEE ROW CROPS Sulfur (S) deficiencies have become more common in recent years. This publication outlines the importance and role of S in higher plants, summarizes recent research, and defines the University of Tennessee’s current S recommendations for row crops. Tyson B. Raper1, Angela T. McClure2, Frank Yin3 and Blake Brown4 1Assistant Professor, Cotton and Small Grains Specialist, Department of Plant Sciences 2Associate Professor, Corn and Soybean Specialist, Department of Plant Sciences 3Associate Professor, Cropping Systems Agronomist, Department of Plant Sciences 4Director, AgResearch and Education Center at Milan INTRODUCTION Sulfur (S) deficiencies have become more common in recent years due to a reduction in S deposition. Research at the University of Tennessee has begun to answer several key questions on crop response to applications of this nutrient. The objective of this publication is to outline the importance of S and the role it plays within higher plants, describe why the deficiencies are becoming more common, summarize recent research and define the University of Tennessee’s current S recommendations for Tennessee row crops. THE ROLE AND IMPORTANCE OF SULFUR IN HIGHER PLANTS Sulfur is an important nutrient in living systems; it is contained within four common amino acids that assist in the synthesis, structure and function of proteins (Brosnan & Brosnan, 2006). In plant nutrition, S is classified as a macronutrient since it is required in quantities much larger than most micronutrients. Within the macronutrient classification, S falls within the secondary nutrient subclassification along with calcium and magnesium. Although S isn’t a primary macronutrient, it is occasionally referred to as the fourth major nutrient (Stewart, 2010), and if contained within a fertilizer, the S percentage is commonly listed as the fourth Figure 1: Most S containing fertilizers have four number in the fertilizer analysis or grade numbers reported in the analysis or grade, with the first (Figure 1).

A Novel Exchange Method to Access Sulfated Molecules Jaber A
www.nature.com/scientificreports OPEN A novel exchange method to access sulfated molecules Jaber A. Alshehri, Anna Mary Benedetti & Alan M. Jones* Organosulfates and sulfamates are important classes of bioactive molecules but due to their polar nature, they are both difcult to prepare and purify. We report an operationally simple, double ion- exchange method to access organosulfates and sulfamates. Inspired by the novel sulfating reagent, TriButylSulfoAmmonium Betaine (TBSAB), we developed a 3-step procedure using tributylamine as the novel solubilising partner coupled to commercially available sulfating agents. Hence, in response to an increasing demand for complementary methods to synthesise organosulfates, we developed an alternative sulfation route based on an inexpensive, molecularly efcient and solubilising cation exchanging method using of-the-shelf reagents. The disclosed method is amenable to a range of diferentially substituted benzyl alcohols, benzylamines and aniline and can also be performed at low temperature for sensitive substrates in good to excellent isolated yield. Organosulfates and sulfamates contain polar functional groups that are important for the study of molecu- lar interactions in the life sciences, such as: neurodegeneration1; plant biology2; neural stem cells3; heparan binding4; and viral infection5. Recent total syntheses including 11-saxitoxinethanoic acid6, various saccharide assemblies7–10, and seminolipid11 have all relied on the incorporation of a highly polar organosulfate motif. Importantly, the frst in class organosulfate containing antibiotic, Avibactam12, has led to the discovery of other novel β-lactamase inhibitors 13,14. Despite the importance of the sulfate group, there remain difculties with the ease of their synthesis to enable further biological study. Our own interest in developing sulfated molecules resulted from a medicinal chemistry challenge to reliably synthesise sulfated glycomimetics 15–18.

5. POTENTIAL for HUMAN EXPOSURE 5.1 OVERVIEW Sulfur
SULFUR DIOXIDE 111 5. POTENTIAL FOR HUMAN EXPOSURE 5.1 OVERVIEW Sulfur dioxide has been identified in at least 16 of the 1,467 current or former EPA National Priorities List (NPL) hazardous wastes sites (HazDat 1998). However, the number of sites evaluated for sulfur dioxide is not known. The frequency of these sites within the United States can be seen in Figure 5-l. Atmospheric sulfur dioxide is formed as a by-product of the combustion of fuel from power generation and industrial activities, and by the oxidation of reduced gases in the atmosphere. Volcanic activity also contributes to the levels of atmospheric sulfur dioxide. The atmospheric lifetime of sulfur dioxide is about 10 days (IARC 1992). Sulfur dioxide is oxidized rapidly by both homogeneous and heterogeneous reactions and is removed from the atmosphere by precipitation and by dry deposition on surfaces, mainly as sulfuric acid. Inhalation of sulfur dioxide, by the general population residing near industrial sources and by workers exposed to sulfur dioxide, is generally the main route of human exposure to the chemical. It should be noted that the amount of sulfur dioxide detected by chemical analysis is not necessarily the amount that is bioavailable. 5. 2 RELEASES TO THE ENVIRONMENT Releases of sulfur dioxide to the environment from large processing facilities are not required to be reported to the Toxics Release Inventory (TRI). Releases of sulfur dioxide are not required to be reported under SARA Section 3 13. Consequently, there are no data for this compound in the current TRI. Sulfur dioxide has been identified in a variety of environmental media (air, surface water, groundwater, soil, and sediment) collected at 16 of the 1,467 NPL hazardous waste sites (HazDat 1998).

MAGNESIUM SULFATE Chemical and Technical Assessment
MAGNESIUM SULFATE Chemical and Technical Assessment Revised by Madduri V. Rao, Ph.D. for the 68th JECFA (Original prepared by Yoko Kawamura, Ph.D. for the 63rd JECFA) 1. Summary Magnesium sulfate was evaluated by the Committee at its 63rd meeting. The outstanding information on functional uses other than nutrient supplement as well as information on commercial use of anhydrous magnesium sulfate and magnesium sulfate was requested for evaluation by the 68th JECFA meeting. Magnesium sulfate is commercially available as heptahydrate, monohydrate, anhydrous or dried form containing the equivalent of 2 - 3 waters of hydration. Magnesium sulfate occurs naturally in seawater, mineral springs and in minerals such as kieserite and epsomite. Magnesium sulfate heptahydrate is manufactured by dissolution of kieserite in water and subsequent crystallization of the heptahydrate. Magnesium sulfate is also prepared by sulfation of magnesium oxide. It is produced with one or seven molecules of water of hydration or in a dried form containing the equivalent of about 2 - 3 waters of hydration. Magnesium sulfate is available as brilliant colourless crystals, granular crystalline powder or white powder with a bitter salty cooling taste. Crystals effloresce in warm, dry air. It is freely soluble in water, very soluble in boiling water, and sparingly soluble in alcohol. Magnesium sulfate is used as a nutrient, firming agent and flavour enhancer. It is also used as a fermentation aid in the processing of beer and malt beverages. No food uses have been identified for the anhydrous form of magnesium sulfate. 2. Description Magnesium sulfate occurs with one (monohydrate), seven (heptahydrate), or no (anhydrous) molecules of water of hydration.
