Fire Fighting · 2 条

Excerpt from ERG Guide 171 [Substances (Low to Moderate Hazard)]:

In case of fire in the surroundings, use appropriate extinguishing media.

First Aid Measures · 4 条

Fresh air, rest.

Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth.

First AidConsult physician in case of ingestion or severe irritation.
Safe StorageSeparated from strong oxidants, strong bases and acids. Cool.
Fire Fighting Procedures · 2 条

If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire (material itself does not burn or burns with difficulty).

Use dry chemical, carbon dioxide; water spray; or alcohol foam extinguishers. Poisonous gases are produced in fire, including ammonia gas and nitrogen oxides. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position. ... The only respirators recommended for fire fighting are self-contained breathing apparatuses that have full face-pieces and are operated in a pressure-demand or other positive-pressure mode.

Storage Conditions · 2 条

Store below 33 °C

Store in tightly closed containers in a cool, well-ventilated area away from caustics (such as sodium hydroxide or potassium hydroxide), because ammonia gas is released.

Ecotoxicity Excerpts · 4 条

/AQUATIC SPECIES/ Seventy one toxicity tests were carried out on rainbow trout ranging in size from sac fry (<0.1g) to 4 year old adults (2.6 kg), in water of uniform chemical composition. Fish susceptibility to NH3 decreased with increasing weight over the range 0.06-2.0 g, but gradually increased above that weight range. LC50 values for 12- and 35-day exposures did not differ greatly from 96-hour values of 0.16-1.1 mg/L. No statisticaly significant differences in results were observed when different ammonium salts (NH4Cl, NH4HCO3, (NH4)2HPO4, (NH4)2SO4) were used.

/AQUATIC SPECIES/ Acute ammonia toxicity in rainbow trout was studied by intraarterial injection of ammonium chloride & ammonium bicarbonate. Ammonium bicarbonate incr arterial blood pH, & ammonium chloride decr arterial blood pH, but the same dose of each was required to kill.

/AQUATIC SPECIES/ The effects of /ammonium bicarbonate/ on the early stages of development of Atlantic salmon were studied. The first set of studies, at 13 °C, lasted 53 days and was carried out within the range 0.001 to >6.6 mg NH3/L beginning with the "formed embryo" stage. Accelerated hatching was observed with increasing ammonium carbonate concentrations, but concentrations >0.16 mg NH3/L were lethal for emerging larvae within 12-36 hours. Growth inhibition was observed at 0.07 mg NH3/L. Tissue changes were observed in eyes, brain, fins, and blood of embryos and larvae exposed to concentrations ranging from 0.16 to 6.6 mg NH3/L with more marked changes at higher ammonia concentrations. Reaction to light and mechanical stimulation gradually disappeared with increased ammonia concentration, and the heart rate slowed. Morphological differences in development between experimental and control larvae were observed since 10th day of exposure. At concentrations up to 0.07 mg NH3/L, no significant morphological differences were observed.

/OTHER TERRESTRIAL SPECIES/ The effect of endogenous ammonia produced in dead fish or ammonia in ammonium bicarbonate solutions was evaluated on the viability of Clonorchis sinensis metacercariae. Viability was determined by worm recovery in rats infected with metacercariae exposed to ammonia in decaying fish or in vitro solutions. The recovery rates were 58%, 48%, 44% and 2% in fish that had been allowed to decay for 5, 10, 20 and 30 days at 4 degrees C, respectively, and this rate ( Y) was inversely correlated with the ammonia concentration ( X) in fish muscle extract ( Y=80.62-0.0667 X, r(2)=0.905, P=0.049). C. sinensis metacercariae barely survived in ammonia solutions with concentrations exceeding 1 g N/L.

药理信息

Mechanism of ActionAmmonium bicarbonate inhibits fungi because the bicarbonate anion supplies the alkalinity necessary to establish an antifungal concentration of free ammonia.
Metabolism/MetabolitesAmmonium bicarbonate dissociated into free ammonia at level of cell membrane.
Absorption, Distribution and ExcretionThere appears to be a more rapid excretion of ammonia following ammonium bicarbonate infusions, which result in higher unionized ammonia levels in blood compared, with those following ammonium chloride infusions.
