The number of weeks your baby was premature: 6 weeks. Subtract the number of weeks premature from the chronological age: 20 weeks minus 6 weeks equal 14 weeks. 14 weeks is your baby's adjusted age.
The use of chemical fertilizer containing anhydrous ammonia can lead to exposure. Outdoor exposure to high levels of anhydrous ammonia can result from leaks and spills at production plants and storage facilities, and from pipelines, tank trucks, railcars, or ships and barges that transport ammonia.
Ammonia is a colourless gas with a characteristic pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules; the liquid boils at â33.3 Â°C (â27.94 Â°F), and freezes at â77.7 Â°C (â107.86 Â°F) to white crystals.H 3 boils at â33.34 Â°C (â28.012 Â°F) at a pressure of one atmosphere, so the liquid must be stored under pressure or at low temperature. Household ammonia or ammonium hydroxide is a solution of NH 3 in water.
