OECD SIDS AMMONIUM SULFATE 4. ECOTOXICITY ID: 7783-20-2 DATE: 18.04.2006 a dysfunction in the liver and thyroid causing alterations in the physiology of the fish, however no mode of toxicity could be deduced. The effect on the adrenals was also examined after exposure to 100 and 500 ppm for 6 months. Fish exposed to 500 ppm appeared stressed, but no mortality occurred. The cortical (corticosteroid producing) cells of the adrenals in both treated groups showed extensive hyperplasia, degranulation, involution and exhaustion. The histopathological findings showed a slight hypertrophy at 100 ppm whereas at 500 ppm atrophic changes occurred. Reliability: (2) valid with restrictions basic data are given 26-JAN-2004 (92) 4.5.2 Chronic Toxicity to Aquatic Invertebrates 128 UNEP PUBLICATIONS
OECD SIDS AMMONIUM SULFATE 4. ECOTOXICITY ID: 7783-20-2 DATE: 18.04.2006 TERRESTRIAL ORGANISMS 4.6.1 Toxicity to Sediment Dwelling Organisms 4.6.2 Toxicity to Terrestrial Plants Species: other terrestrial plant: onion (allium cepa L. - Norstar 210B) Endpoint: growth Expos. period: 84 day(s) Method: other: see Test Condition Year: 1995 GLP: no data Result: Yield (dry weight per pot) was greatest for 133 mg N per kg soil. An inhibitory effect was found at 399 and 532 mg N per kg soil, except for the sandy soil where only the 532 mg N per kg soil ammonium sulfate was inhibitory. Test condition: The effects of several nitrogen compounds on the growth of onion was studied in 4 Canadian soils (pH range 5.0 to 6.6, organic matter range 6-41.5 g/kg, sand or silty or sandy loams, podzols or gleysols). Hydrated lime was added to the lower pH soils to raise the pH to near 6.5, and P, K and Mg were added to all soils to prevent deficiencies. After seiving, air drying and moisture adjustment to 80% water holding capacity, the soils were placed in 3.2 l plastic pots, into which four 14 day old onion seedlings were transplanted. Ammomium sulfate was added at 0, 133, 266, 399, and 532 mg N per kg soil. The growth chamber was maintained at 22-18C and a 16-8 h day/night cycle, 65% relative humidity, and 300µE m-2 s-1 photon flux density at plant height. Immature plants were harvested 84 days after transplanting. Bulbs, roots, and leaves were separated, and fresh and dry weights of all plant parts were determined. Reliability: (1) valid without restriction Flag: Critical study for SIDS endpoint 22-JUL-2004 (93) Species: Expos. period: Unit: other terrestrial plant: Avena sterilis spp Macrocarpa Mo. 21 day(s) mg/l Method: other: see Test Condition Year: 1989 GLP: no data Test substance: other TS: ammonium sulfate, no further details Remark: Result: Test condition: ppm is specified in the test, not ppm N. Note no control of pH or ionic strength No significant increase in germination rate compared with the control. At 5000 ppm, an inhibitory effect was found. The effects of several nitrogen compounds on the germination of the first seed of each spikelet of Avena sterilis spp Macrocarpa Mo. was studied at 15 C, or at alternating temperatures of 15 C (16 hours) and 5 C (8 hours). 100 seeds taken at random were placed in a covered Petrie dish, wrapped in filter paper soaked in 20 ml of the test solution. Concentrations studied are 0, 100, 1000, 2500, and UNEP PUBLICATIONS 129
