Research has shown that ammonia concentrations as low as 25 ppm can reduce bird weights at 28 days of age by two to seven percent while 50 ppm ammonia has been shown to reduce bird weights from 16 and 19 percent (F.N. Reece et. … 2016-12-15 I want to calculate how much ammonia evaporates from a 10% ammonia solution (ammonium hydroxide solution), to check if the concentration of ammonia in the air exceeds 25 ppm. The temperature is 40°C. The ammonia exposure (from sewer air and industrial leakage) also contribute significantly for climate change and human health hazard 4,5,6. Exposure to 500 ppm ammonia causes immediate irritation Ammonia (NH₃) Lower Detection Limit : 1 ppm-v: Measurement range : 0 – 1%: Accuracy : 2% of reading or 1 ppm, whichever is greater: Linearity : Better than 1%: Resolution : 1 ppm: Drift : Negligible (<2% of measurement range between maintenance intervals) Sampling rate : 1 second: Response time (T90) NH₃ in N₂ 1% to 0% in < 4 sec 0.4 mg/l (ppm) of ammonia to water to increase and extend the disinfecting ability of chlorine.
