RFC: IRIS Barium and Compounds Substance File
October 29, 2002 Information Quality Guidelines Staff Mail Code 28221T U.S. EPA 1200 Pennsylvania Ave., N.W. Washington, DC, 20460 Subject: Request for Correction of the IRIS Barium and Compounds substance file - Information disseminated by EPA that does not comply with EPA or OMB Information Quality Guidelines Dear Madam or Sir; Chemical Products Corporation (CPC), a Georgia corporation which produces Barium and Strontium chemicals at its Cartersville, Georgia facility, hereby submits this Request for Correction (RFC) concerning EPA’s Integrated Risk Information System Barium and Compounds Substance File (IRIS Ba File). The influential information contained in this file fails to comply with the OMB “Guidelines for Ensuring and Maximizing the Quality, Objectivity, Utility, and Integrity of Information Disseminated by Federal Agencies”. The information disseminated in EPA’s IRIS Barium and Compounds file directly contradicts the information published by EPA in the January 3, 1997 Federal Register and, therefore, cannot represent an EPA consensus position. The IRIS Ba File was revised in 1998 and 1999, yet it contains no mention of the toxicological evaluation conducted by EPA’s Office of Pollution, Pesticides, and Toxic Substances reported in 62 FR 366-372 (No. 2, January 3, 1997). There is no explanation of how a radically different interpretation of the same data could be justified. The NOAEL employed to calculate the Oral Reference Dose in the IRIS Ba File is 0.21 mg/kg/day; there is no LOAEL associated with this NOAEL. The NOAEL reported in 62 FR 366-372 is 70 mg/kg/day in rats and 165 mg/kg/day in mice; these values are taken from a National Toxicology Program technical report and are associated with a LOAEL of 180 mg/kg/day. -

Of the Periodic Table
of the Periodic Table teacher notes Give your students a visual introduction to the families of the periodic table! This product includes eight mini- posters, one for each of the element families on the main group of the periodic table: Alkali Metals, Alkaline Earth Metals, Boron/Aluminum Group (Icosagens), Carbon Group (Crystallogens), Nitrogen Group (Pnictogens), Oxygen Group (Chalcogens), Halogens, and Noble Gases. The mini-posters give overview information about the family as well as a visual of where on the periodic table the family is located and a diagram of an atom of that family highlighting the number of valence electrons. Also included is the student packet, which is broken into the eight families and asks for specific information that students will find on the mini-posters. The students are also directed to color each family with a specific color on the blank graphic organizer at the end of their packet and they go to the fantastic interactive table at www.periodictable.com to learn even more about the elements in each family. Furthermore, there is a section for students to conduct their own research on the element of hydrogen, which does not belong to a family. When I use this activity, I print two of each mini-poster in color (pages 8 through 15 of this file), laminate them, and lay them on a big table. I have students work in partners to read about each family, one at a time, and complete that section of the student packet (pages 16 through 21 of this file). When they finish, they bring the mini-poster back to the table for another group to use. -

Paediatric Barium Swallow/Meal Information for Parents and Carers Your Doctor Has Referred Your Child for a Barium Swallow/Meal to Look at Their Food Pipe and Stomach
Oxford University Hospitals NHS Trust Paediatric Barium Swallow/Meal Information for parents and carers Your doctor has referred your child for a barium swallow/meal to look at their food pipe and stomach. We have written this information leaflet to help you and your child to understand this test. We hope it answers some of the questions you both may have and helps you and your child to feel more prepared and relaxed. page 2 What is a barium swallow/meal? A barium swallow/meal uses a special liquid to allow the X-ray doctor (radiologist) to see your child’s oesophagus (food pipe or gullet), stomach and the first part of their intestines using an X-ray camera. What does this test involve? Your child will be asked to drink a special drink called barium. This is a white liquid with a chalky texture. It is not radioactive but is used as it shows up well on X-ray images. Your child will need to drink the barium whilst lying on a couch with the X-ray camera over their tummy (about 75cm away). They may need to change position, so you will be asked to stay close to them at all times to make sure they are safe. If your child is able to, they will usually be asked to drink using a straw so that they can stay lying down. If they are not able to use a straw they can drink the barium from a bottle or beaker. If they are currently being fed through a nasogastric (NG) tube, we will use that to give them the barium. -

Units of Solubility
Units of solubility Continue Calculating the molyal saltiness of the compound in the water and the relative molyal saltiness of the compounds of the salted substance product (Ksp) is the ratio of concentrations in balance. The molar nozzle compound can be calculated directly from its product. Even though the solubility products of the two compounds are similar, their molar solubilities can be very different. Scientists use relative solubilities of compounds to separate or identify them. The product of the substance (Ksp) is the ratio of concentrations in balance. Molar solubility, which is directly related to the soluble product, is the number of moles soluble solution, which can dissolve per liter of solution before the solution becomes saturated. Once the solution is saturated, any additional solution is sucked out of the solution. Units of Molar (M), or mole liter-1 (mole / l). Calculating the Molar Solubility Link between molar solubility and solubility product means that one can be used to find the other. Illustration 1: Ksp for AgI is 8.5 x 10-17 at 25 degrees Celsius. What is molar solubility? (Let's - solubility compounds in water are usually defined as x in the ICE table.) Solution: Balanced Equation for Reaction: LatexAgI (s) left-right ag (aq) and I - aq)/latex Formula for Ksp: Ksp AgI-Ksp s2 8.5 x 10-17 where s concentration of each ion on balance. Now, solve for s: s2 - 8.5 x 10- 17 s . Example 2: Solubility products for cadmium carbonate (CdCO3) and silver carbonate (Ag2CO3) are almost exactly the same. Compare their molar solubilities in the water at 25 degrees Celsius. -
Toxicological Profile for Barium and Barium Compounds
TOXICOLOGICAL PROFILE FOR BARIUM AND BARIUM COMPOUNDS U.S. DEPARTMENT OF HEALTH AND HUMAN SERVICES Public Health Service Agency for Toxic Substances and Disease Registry August 2007 BARIUM AND BARIUM COMPOUNDS ii DISCLAIMER The use of company or product name(s) is for identification only and does not imply endorsement by the Agency for Toxic Substances and Disease Registry. BARIUM AND BARIUM COMPOUNDS iii UPDATE STATEMENT A Toxicological Profile for Barium and Barium Compounds, Draft for Public Comment was released in September 2005. This edition supersedes any previously released draft or final profile. Toxicological profiles are revised and republished as necessary. For information regarding the update status of previously released profiles, contact ATSDR at: Agency for Toxic Substances and Disease Registry Division of Toxicology and Environmental Medicine/Applied Toxicology Branch 1600 Clifton Road NE Mailstop F-32 Atlanta, Georgia 30333 BARIUM AND BARIUM COMPOUNDS iv This page is intentionally blank. v FOREWORD This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the hazardous substance described therein. Each peer-reviewed profile identifies and reviews the key literature that describes a hazardous substance's toxicologic properties. Other pertinent literature is also presented, but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced.
