The supply of these elements in the soil has become limited in some areas as a result of the introduction of high yielding varieties, better and more intensive cropping practices, and increased use of high analysis fertilisers. In some cases, the ob- served deficiencies of these micronutrients have been man- made due to addition of interfering elements for other pur- poses. For instance there is the copper induced iron chlorosis, copper being introduced as agricultural sprays and the phosphorus induced iron and zinc deficiencies, phos- phorus being introduced to meet the phosphorus requirement of farm crops. How to minimise such interactions and the problems of keeping these micronutrient elements available to the plants when applied to the soil have been the sub- ject of intensive researches.

Pacific Northwest Forest and Range Experiment Station, Portland, Oregon. Twelve different nitrogen (N) fertilizer treatments were tested on potted western hemlock (Tsuga heterophylla (Raf. ) Sarg.) seedlings. Fertilizers affected soil N and pH, and growth and foliar chemical com­ position of seedlings. Ura plus N-Serve and sulfur-coated urea appear more promising for promoting growth than other fertilizers tested. Results, however, do not explain reported variability in response of hemlock stands to N fertilization. Keywords: Nitrogen fertilizer response, seedling growth, western hemlock, Tsuga heterophylla.

    SIAM 24, 17-20 April 2007 US/ICCA SIDS INITIAL ASSESSMENT PROFILE CAS Nos. 7722-76-1, 7783-28-0, 68333-79-9, 8011-76-5, 65996-95-4 Phosphate category: Monoammonium phosphate (MAP), Chemical Names Diammonium phosphate (DAP), Ammonium polyphosphate (APP), Single superphosphate (SSP), Triple superphosphate (TSP) MAP: NH4H2PO4 DAP: (NH4)2HPO4 Structural Formula APP: SSP: main components:Ca(H2PO4)2. H2O /CaSO4.H2O TSP: CaHPO4.2H2O SUMMARY CONCLUSIONS OF THE SIAR Category/Analogue Rationale The category consists of monoammonium phosphate (MAP; CAS No. 7722-76-1), diammonium phosphate (DAP; CAS No. 7783-28-0), ammonium polyphosphate (APP; CAS No. 68333-79-9), single superphosphate (SSP; CAS No. 8011-76-5), and triple superphosphate (TSP; CAS No. 65996-95-4). All members of the category are mainly or exclusively used as fertilizer and have one common functional group (phosphate) that equilibrates between several different ionic species - = = -3 [H3PO4, H2PO4 , HPO4 , HPO4 , or PO4 ] depending on the pH of the environment. Thus, chemical reactions for all compounds in this category are similar with the exception of the actual dissociation product, which forms calcium or ammonia along with common phosphate moieties. However, the presence of the ammonium ion will influence the observed toxicity and its data are used to conservatively represent the toxicity of the category members. Under typical environmental conditions, the phosphate would be present as monohydrogen = - - phosphate (HPO4 ) or dihydrogen phosphate (H2PO4 ) with the equilibrium favoring H2PO4 as the acidity of the environment increases. Under these conditions, the proportions of phosphoric acid -3 (H3PO4) and the phosphate anion (PO4 ) would be extremely low.

  • 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.

Aluminum Bromide LL– Aluminum Chloride L L – Aluminum Fluoride (0-25%) L L – This chart shows chemical resistance of our various Aluminum Hydroxide LLL 1 topping materials (90 mils – ⁄4"). These ratings are based on Aluminum Iodide LL– temperatures being ambient. At higher temperatures, chemical Aluminum Nitrate LL– resistance may be effected. When chemical exposure is Aluminum Sodium Chloride L L – minimal to non-existent, a 9000 System–FlorClad™ HD or Aluminum Sulfate LLL 4600 System– BriteCast™ HD may be used. Alums L L L 2-Aminoethoxyethanol Resistance data is listed with the assumption that the material GGG has properly cured for at least four days, at recommended Ammonia – Wet L L – temperatures, prior to any chemical exposure.
