Indoor Human Exposure and Ozone Measurement: Protect Your Health

What is Ozone Measurement? What is the Limit for Human Exposure?

Ozone (O₃) is a powerful oxidant that can be formed by both natural processes and human activities. Indoor ozone accumulation can pose serious health risks, especially for individuals living and working indoors.

What is ozone and how is it formed?

Ozone is a colorless gas consisting of three oxygen atoms. While it blocks harmful ultraviolet (UV) rays as part of a structure known as the ozone layer in the upper layers of the atmosphere, ozone at levels near the earth's surface can be dangerous to human health.

Indoor Ozone Sources:

• Photocopiers, printers and other electronic devices.
• Air purifiers and ionizers.
• Some cleaning products and chemicals.
• Infiltration of vehicle exhaust gases.

Health Effects of Ozone Exposure

Long-term exposure to high ozone levels can lead to both short-term and long-term health problems:

1. Respiratory System Problems:
• May cause coughing, shortness of breath and throat irritation.
• May worsen symptoms in asthma patients.
2. Eye and Skin Irritation:
• Ozone exposure can cause burning sensation in the eyes and dry skin.
3. Long-Term Effects:
• Continued exposure can weaken lung function and cause respiratory diseases.
4. Effects on Performance and Comfort:
• High ozone levels can adversely affect the concentration and productivity of workers in the workplace.

Indoor Ozone Measurement Methods

Accurately detecting ozone levels is critical to minimizing health risks. The main measurement methods used today are:

1. Electrochemical Sensors:
• Measures ozone concentration with small and portable devices.
• Low cost and easy to use.
2. Photometric Methods:
• Determines the concentration using ozone's ability to absorb UV rays.
• Provides precise and accurate measurements.
3. Chemical Adsorption Tubes:
• Collects air samples and determines the amount of ozone by laboratory analysis.
• Provides detailed and reliable results.
4. Online Monitoring Systems:
• Provides continuous ozone monitoring and reporting.
• Suitable for instant monitoring of indoor environmental quality.

Ways to Protect from Ozone Exposure

You can follow these steps to control indoor ozone levels and prevent exposure:

1. Ventilation:
• Regularly open windows to allow fresh air to flow.
• Change the filters of mechanical ventilation systems frequently.
2. Limit Ozone Producing Devices:
• Avoid ozone-emitting air purifiers.
• Operate electronic devices in low-use or well-ventilated areas.
3. Air Quality Monitoring:
• Monitor the risk level by taking regular ozone measurements indoors.
• Limit indoor activities during hours of high ozone concentration.
4. Reduce Chemical Products:
• Avoid cleaning products that increase ozone emissions.
• Use natural and environmentally friendly alternatives.
