Toxicological Profile for Nitrate and Nitrite
NITRATE AND NITRITE 9 2. RELEVANCE TO PUBLIC HEALTH 2.1 BACKGROUND AND ENVIRONMENTAL EXPOSURES TO NITRATE AND NITRITE IN THE UNITED STATES Nitrate and nitrite can be organic or inorganic chemicals depending on their chemical structures. This profile pertains to inorganic nitrate and nitrite, specifically the nitrate anion and the nitrite anion. Nitrate and nitrite occur naturally in the environment as part of the nitrogen cycle, and are produced both endogenously and exogenously. Ammonia-oxidizing bacteria convert ammonia into nitrite; nitrite- oxidizing bacteria convert nitrite into nitrate in aerobic environments. This two-stage process is known as nitrification. Main sources of ammonia in the environment are decaying organic matter and human and animal wastes. Nitrification, atmospheric fixation, and nitrogen fertilizers contribute to nitrite and nitrate concentrations in the environment. In nature, salts of nitrate and nitrite completely dissociate and these anions typically exist as ionic species. In the environment, nitrite is readily oxidized to nitrate. Nitrate is generally stable in the environment; however, it may be reduced through biotic (living systems; plants, microbes, etc.) processes to nitrite under anerobic conditions. Nitrate and nitrite are ubiquitous in the environment and people are exposed to them primarily through the ingestion of food and drinking water. Significant uptake of nitrate and nitrite occurs in all varieties of plants; internal storage of nitrate (rather than metabolic conversion to ammonium and amino acids) can occur in some plants, especially leafy vegetables such as lettuce and spinach. Vegetables account for about 80% of the nitrate in a typical human diet. Nitrate and nitrite are also produced in the body as part of the natural nitrate-nitrite-nitric oxide cycle.

[120 pages] WESTON personnel collected six sediment samples (including one environmental duplicate sample) from five locations along the surface water pathway of the Canadian Radium & Uranium Corp. (CRU) site in May 2014. The sediment samples were analyzed for Target Analyte List (TAL) Metals and Stable Lead Isotopes. 1. TAL Lead Interpretation: In order to quantify the significance for Lead, Thallium and Mercury the following was performed: 1. WESTON personnel tabulated all available TAL Metal data from the May 2014 Sediment Sampling event. 2. For each analyte of concern (Lead, Thallium, and Mercury), the highest background concentration was selected and then multiplied by three. This is the criteria to find the significance of site attributable release as per Hazard Ranking System guidelines. 3. One analytical lead result (2222-SD04) of 520 mg/kg (J) was qualified with an unknown bias. In accordance with US EPA document “Using Data to Document an Observed Release and Observed Contamination”, 2222-SD03 lead concentration was adjusted by dividing by the factor value for lead of 1.44 to equal 361 mg/kg.

Prohibited and Restricted Chemical List
School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List PROHIBITED AND RESTRICTED CHEMICAL LIST Introduction After incidents of laboratory chemical contamination at several schools, DCPS, The American Association for the Advancement of Science (AAAS) and DC Fire and Emergency Management Services developed an aggressive program for chemical control to eliminate student and staff exposure to potential hazardous chemicals. Based upon this program, all principals are required to conduct a complete yearly inventory of all chemicals located at each school building to identify for the removal and disposal of any prohibited/banned chemicals. Prohibited chemicals are those that pose an inherent, immediate, and potentially life- threatening risk, injury, or impairment due to toxicity or other chemical properties to students, staff, or other occupants of the school. These chemicals are prohibited from use and/or storage at the school, and the school is prohibited from purchasing or accepting donations of such chemicals. Restricted chemicals are chemicals that are restricted by use and/or quantities. If restricted chemicals are present at the school, each storage location must be addressed in the school's written emergency plan. Also, plan maps must clearly denote the storage locations of these chemicals. Restricted chemicals—demonstration use only are a subclass in the Restricted chemicals list that are limited to instructor demonstration. Students may not participate in handling or preparation of restricted chemicals as part of a demonstration. If Restricted chemicals—demonstration use only are present at the school, each storage location must be addressed in the school's written emergency plan. Section 7: Appendices – October 2009 37 School Emergency Response Plan and Management Guide Prohibited and Restricted Chemical List Following is a table of chemicals that are Prohibited—banned, Restricted—academic curriculum use, and Restricted—demonstration use only.
