Ozone (O3)

Pollutants - Gases - Ozone O3


AirQuality Limited can offer a variety of monitoring options for the monitoring of O3 including:

  • O3 Direct-reading instrumental method
  • O3 Gas Sensitive Semiconductor
  • O3 Electrochemical Sensor

More detail on each of these options is shown below:

O3 Direct reading Instrumental Method
The direct reading ozone analyser is a reference standard instrument which can meet the requirements of AS 3580.6.1-2011 : Determination of ozone – Direct-reading instrumental method. The correct operation of this instrument requires a temperature controlled enclosure.

O3 Gas Sensitive Semiconductor
The AirQuality Gasmote-O3 gas sensitive semiconductor (GSS) technology uses advanced heated metal oxide technologies in combination with data-logging, communications and global positioning systems.

  •  Capable of high quality indicative O3 measurement
  •  Continuous measurement, automated data up-load


Pricing is dependent upon:

  • The length of time you wish to monitor for
  • The type of equipment you wish to use
  • Whether you wish to purchase or rent the monitoring instrumentation
  • The level of data validation and reporting
  • Whether an instrument enclosure is required
  • Whether mains or solar powered options are required
  • Whether wind speed and direction also need to be measured

Our clients tell us that we offer very competitive quotes for both the supply and operation of these instruments.

The health impacts of exposure to ozone concentrations have been widely studied using both epidemiological methods and laboratory studies. Dennison et al (2002) summarizes the health effects associated with exposure to ozone as:

  • increase in daily mortality, respiratory and cardiovascular disease
  • increase in hospital admissions and emergency room visits
  • respiratory and cardiovascular disease
  • decrease in lung function
  • increase in symptoms of respiratory illness such as cough, phlegm and wheeze
  • increase in bronchodilator usage

At low concentrations ozone can cause tissue injuries in the lungs and can result in significant impairment of pulmonary function. The impact of ozone on health depends on a number of factors including magnitude of concentration, duration of exposure, climate, individual sensitivity and pre-existing conditions. Those most susceptible to concentrations of ozone include children, people with pre-existing diseases, the elderly and healthy adults exercising in the outdoors.

Although some studies have indicated the potential for a no effects threshold, the overall interpretation of the health effects literature is that there is no threshold of exposure, below which effects do not occur (Dennison et al, 2002). A dose response relationship of 0.6% per 10 µgm-3 (eight-hour mean) for mortality and 0.7% per 10 µgm-3 (eight-hour mean) for hospital admissions was used to estimate the impact of ozone concentrations in the Quantification of the Effects of Air Pollution on Health in the United Kingdom study (Department of Health, 1998). This dose response relationship was based on studies carried out in the urban and rural areas of the United Kingdom during the summer months, prior to 1998.
