  • Reregistration Eligibility Decision (RED) for Inorganic Sulfites
    Reregistration Eligibility Decision – Inorganic Sulfites May 2007 Reregistration Eligibility Decision Inorganic Sulfites Special Review and Reregistration Division Office of Pesticide Programs U.S. Environmental Protection Agency 1801 South Bell Street Arlington, VA 22202 Introduction The Environmental Protection Agency (EPA) has completed its Reregistration Eligibility Decision (RED) for the inorganic sulfites case, which includes the chemicals sulfur dioxide and sodium metabisulfite. This assessment provides information to support the issuance of a Reregistration Eligibility Decision for inorganic sulfites. EPA’s pesticide reregistration process provides for the review of older pesticides (those initially registered prior to November 1984) under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to ensure that they meet current scientific and regulatory standards. In this document, EPA presents the results of its review of the potential human health effects of dietary, drinking water and occupational/bystander exposure to inorganic sulfites, as well as its ecological risk findings. Evaluations performed by the World Health Organization (WHO), the International Agency for Research on Cancer (IARC), and the Agency for Toxic Substances and Disease Registry (ATSDR) were relied upon for this assessment, in addition to peer-reviewed evaluations performed by the Cosmetic Ingredient Review (CIR), the Organization for Economic Cooperation and Development-Screening Information Data Set (OECD-SIDS) and from other open literature sources. Based on this assessment, the Agency has determined that products containing sulfur dioxide or sodium metabisulfite are eligible for reregistration provided the necessary label changes are made. As a result of this assessment, one tolerance has been reassessed. I. Use Information The inorganic sulfites reregistration case includes the chemicals sulfur dioxide (CAS No.

The aim of this study was to identify the potential reaction to sodium metabisulfite (MBS) based on a placebo-controlled oral challenge in patients with urticaria and suspected hypersensitivity to food additives. Materials and Methods: A total of 110 adult patients (76 females and 34 males with a mean age of 46 years) were included in the study between 2017 and 2019. All subjects underwent MBS skin prick tests (SPT) and patch tests (PT). Patients with a positive skin test or suspected MBS hypersensitivity were qualified for a placebo-controlled oral challenge (OC). Results: Skin testing was positive in 24 patients: SPT in 20% (n = 22), PT in 5% (n = 6). Out of 64 oral challenges, 13 positive results were obtained. Patients with a positive challenge typed sulfite foods twice as often as a culprit compared to those with a negative OC. Conclusions: In patients with urticaria, both the IgE and non-IgE mechanism of MBS hypersensitivity has been demonstrated. Skin tests with a detailed medical history of potentially guilty foods may be helpful in determining sulfite hypersensitivity. Key words: Sulfites; Sodium metabisulfite; Urticaria; Food additive hypersensitivity INTRODUCTION they are not obliged to disclose the total amount of the substance [5].

  • Chemical Pretreatment for RO and NF
    Chemical Pretreatment For RO and NF October 2013 Lenntech [email protected] Tel. +31-152-610-900 www.lenntech.com Fax. +31-152-616-289 There are a number of chemicals that can be introduced into the RO feed to enhance the operation of the RO system. Acids Caustic Dechlorination chemicals Antiscalants and Dispersants Acids: Acids, typically hydrochloric [HCl] or sulfuric [H2SO4], are injected into the RO feed to lower pH. Sulfuric acid is used more often than HCl acid. One reason for this is because sulfuric acid is relatively lower in operating cost than HCl acid. Another advantage to using sulfuric over HCl is the reduced fuming to the atmosphere, which means less corrosion to surrounding metal components. Sulfuric acid is sometimes preferred over HCl since there is a better membrane rejection of the sulfate ion than the chloride ion. Technical grade sulfuric acid, with no other additives, is suitable for use with a RO. Sulfuric acid is commercially available as a 20% and 93% solution. The 93% solution is also referred to as “66 0 Baume solution”. Caution is required in diluting 93% sulfuric acid, since the maximum heat of dilution of about 280 F occurs around 60%. It is critical that the concentrated acid is added slowly to the top of dilution water that is being agitated to minimize the buildup of heat and boiling of the makeup solution. Hydrochloric acid is preferred when calcium sulfate, barium sulfate, or strontium sulfate scaling is a concern. Sulfuric acid increases the sulfate ion level in the RO feed, which directly increases the potential for sulfate-based scaling.
