Measurement and Analysis of NH3 in Ambient Air: Critical Tests for Industrial Safety

What is the Importance of NH3 Measurement in Ambient Air?

Ammonia (NH₃) is a pungent, colorless and highly reactive gas used in many industrial processes. It is especially used in sectors such as agriculture, chemistry, refrigeration and fertilizer production. However, due to its high toxicity and environmental impacts, NH₃ measurement in ambient air is of great importance in terms of occupational health and safety.

What is Ammonia (NH₃) and Why is it Important?

• Chemical Formula NH₃
• Physical Properties: Colorless gas with pungent odor.
• Reactivity: Shows high solubility in water and alkaline properties. It can react with acids to form salt.

What are the Health Effects?

• Exposure at low levels: Respiratory irritation, burning eyes, cough and throat irritation.
• Exposure at high levels: Acute poisoning, lung damage, loss of consciousness and death.
• Occupational health and safety standards require regular monitoring of the concentration of NH₃ in air.

What are the Environmental Impacts?

• Soil and water pollution: Ammonia can cause nitrification and acidification.
• Atmospheric effects: NH₃ reacts with fine particles (PM2.5), adversely affecting air quality.

What are the Safety Limits for NH₃?

• OSHA (Occupational Safety and Health Administration):
• TWA (8-hour time-weighted average): 25 ppm
• STEL (Short-term exposure limit): 35 ppm
• NIOSH (National Institute for Occupational Safety and Health):
• IDLH (Immediately dangerous levels): 300 ppm
• WHO (World Health Organization): The recommended limits of NH₃ for outdoor air quality vary, with low levels around 1 μg/m³ generally recommended.

What are the Application Areas for NH₃ Analysis?

Industrial Areas

• Chemical industry: Leakage control during ammonia production and use.
• Refrigeration systems: Detection of NH₃ leaks in industrial refrigeration systems.

Agriculture

• Fertilization processes: Monitoring the environmental impact of NH₃ release.
• Livestock farming: Measuring the effects of NH₃ gas in barns on workers and animals.

Environmental Monitoring

• Measurement of NH₃ concentrations in the atmosphere, evaluation of air quality.
