Monitoring the environment

Toluene levels in Victorian air 2003–07


Toluene is a component of petrol and is commonly found in industrial solvents.

The chart on this page shows average toluene concentrations measured by EPA at each monitoring site. Average concentrations are presented, as this is the basis on which the health-based monitoring investigation level is set.

All results are well below the health-based monitoring investigation level.

Annual average toluene concentrations for EPA’s toluene studies

Toluene

ppb: parts per billion (for every one billion litres of air there is one litre of the pollutant)

Note: Some projects ran for less than twelve months. More information on individual projects is available on this website.
