EPA staff also note where changes to approvals are needed. Where those changes are not minor or technical, these changes require a reassessment or a modified reassessment of the approval of the substance under the HSNO Act 1996 (“the Act”) The Chemical Review is intended as a means of making changes to a number of approvals at once, taking into account the new information available to the EPA. This is undertaken as a modified reassessment under section 63A of the Act. This application makes recommendations to change some or all of the following aspects of the approvals in this application: - The approval name of the substance - The hazard classification(s) applied to the substance - The controls applied to the substance The controls changes proposed are largely as a result of changes to the hazard classifications of the substances in this application. -
Toxicological Profile for Hydrogen Sulfide and Carbonyl Sulfide
HYDROGEN SULFIDE AND CARBONYL SULFIDE 149 6. POTENTIAL FOR HUMAN EXPOSURE 6.1 OVERVIEW Hydrogen sulfide has been found in at least 34 of the 1,832 waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) and carbonyl sulfide was detected in at least 4 of the 1,832 waste sites (ATSDR 2015). However, the number of sites evaluated for these substances is not known and hydrogen sulfide and carbonyl sulfide are ubiquitous in the atmosphere. The frequency of these sites can be seen in Figures 6-1 and 6-2. Carbonyl sulfide and hydrogen sulfide are principal components in the natural sulfur cycle. Bacteria, fungi, and actinomycetes (a fungus-like bacteria) release hydrogen sulfide during the decomposition of 2- sulfur containing proteins and by the direct reduction of sulfate (SO4 ). Hydrogen sulfide is also emitted from volcanoes, stagnant or polluted waters, and manure or coal pits with low oxygen content (Aneja 1990; Khalil and Ramussen 1984). The majority of carbonyl sulfide that enters the environment is released to air and it is very abundant in the troposphere (Conrad and Meuser 2000; EPA 1994c, 1994d; Meinrat et al. 1992; Simmons et al. 2012; Stimler et al. 2010). It enters the atmosphere from both natural and anthropogenic sources (EPA 1994c, 1994d; Meinrat et al. 1992; Stimler et al. 2010). Carbonyl sulfide is released from wetlands, salt marshes, soil, oceans, deciduous and coniferous trees, and volcanic gases (Blake et al. 2004; EPA 1994c, 1994d; Meinrat et al. 1992; Rasmussen et al. 1982a, 1982b; Stimler et al. -

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 hap pens 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. -

' 3 in SteaM Muffler Effluent ·,·:,· ~Jr l'f·;'.lfR & -..... _, __ . --.-- _,_,-; .'~;ENT The cheMical species generated by the treatMent of geotherMal steaM with sodiuM hydroxide <HaOH> include sodiuM carbonate <Haf0 3>, sodiuM bicarbonate <HaHCO?, sodiuM sulfide <HazS>, and sodiuM bisulfide <HaHS>. The forMer t~o cheMicals are environMentally benign and their disposal will have no significant effect on groundwater quality. SodiuM sulfide and bisulfide can 7 however~ have substantial iMpacts on water quality due to their toxicity at Moderate concentrations and their potential for odor generation at extreMely low concentrations. Hence 7 the fate of these cheMicals under norMal environMental conditions is of concern in considering their production and disposal as a result of treatMent of geotherMal steaM. Hydrogen sulfide abateMent froM geotherMal steaM has been accoMplished in Hawaii by the injection of a lOX solution of sodiuM hydroxide into the steaM phase at a Mole ratio of three Moles of sodiuM hydroxide to one Mole of hydrogen sulfide. The pH of the resultant solution will be in the range of 12 to 13 and hence the predoMinant sulfide species in solution will be sodiuM sulfide- Because a quantitative reaction of hydrogen sulfide to sodiuM sulfide ~auld require only two Moles of caustic to one MOle of sulfide~ an excess of caustic will be present that will Maintain the pH at a high level for a substantial period after the scrubber effluent is exposed to atMospheric air. Upon exposure of the sodiuM sulfide solution to air 7 the Most iMportant reaction that will occur is the oxidation of the sodiuM sulfide. -

Hamilton 3 1 Physics Department, University of Auckland, Symonds Street, Auckland (Email: [email protected] ) 2 DCM Process Control, (Email: [email protected] ; [email protected] ; [email protected] ) 3 Gold Coast City Council (Email: [email protected]; [email protected]; [email protected] ) 4 Advanced Wastewater Management Centre, University of Queensland, (Email: [email protected]; [email protected]; [email protected] ) Abstract Sulfides are particularly problematic in the sewage industry. Hydrogen sulfide causes corrosion of concrete infrastructure, is dangerous at high concentrations and foul smelling at low concentrations. Despite the importance of sulfide monitoring there is no commercially available system to quantify sulfide in situ in waste water. In this article we report on our use of an s::can spectro::lyser TM to quantify bisulfide in waste water and additional analysis with a pH probe to calculate total dissolved sulfide. Our results show it is possible to use existing commercially available and field proven sensors to measure sulfide to mg/L levels continuously with little operator intervention and no sample preparation. Keywords: In-situ, on-line, sulfide, septic sewage, real-time INTRODUCTION Hydrogen sulfide (H 2S) is generated in the aqueous phase of wastewater by bacterial reduction of sulfate under anaerobic conditions (Tanaka et al. , 2000). -
