122 Riccarton Road

This site was established in mid-2006 to provide information about air quality at roadside. Nitrogen dioxide and carbon monoxide have been monitored since 2006 and have not exceeded their guidelines. PM10 was monitored for about a month in winter 2006 and most of 2007, and exceeded the daily guideline a number of times, mainly driven by high evening concentrations. Monitoring of PM10  and PM2.5 started again in early 2017.   

Sulphur dioxide was monitored from late 2007 to early 2008, and concentrations were well below the guidelines. Benzene has been monitored since 2001 and annual average concentrations have been falling steadily over this time, from above guideline to their current levels at around two thirds of the annual guideline.

    What do the dashboard colours mean for nitrogen dioxide?

    The dashboard colours show how nitrogen dioxide levels sit in relation to these guidelines – from green (less than 10%) to red (over the guideline).  The guideline (100% value) for the hourly average is 200 µg/m3, for the daily average 100 µg/m3, and 4µg/m3 for the annual average.  There are no guidelines for monthly data (charcoal colour).

    What is this graph showing me?

    This graph shows how levels of nitrogen dioxide change on an hourly, daily, monthly or annual basis for the selected time period.  Emissions from various sources change, depending on whether it’s a weekday or the weekend or at different times of the year (e.g. emissions from home heating goes up in the cold winter months).  Still conditions often lead to high concentrations, as there is no wind to blow away the pollutants in the air.   The nitrogen dioxide concentrations are shown against the guidelines for air quality (for hourly, daily and annual averages), and where concentrations exceed 100% of the guideline (red line) this can be a cause for concern, especially if this occurs on a frequent basis.  

    Exceedance data (when available) shows the number of hours per year that the concentrations went above 100% of the air quality guideline.

    What do the dashboard colours mean for carbon monoxide?

    The dashboard colours show how carbon monoxide levels sit in relation to the guideline – from green (less than 10%) to red (over the guideline).  The guideline (100% value) for the hourly average carbon monoxide is 30 mg/m3.  There are no guidelines for daily, monthly or annual data (charcoal colour).

    What is this graph showing me?

    This graph shows how levels of carbon monoxide change on an hourly, daily, monthly or annual basis for the selected time period. The levels depend on local sources of emissions and what the weather is doing.  Emissions from various sources change, depending on whether it’s a weekday or the weekend or at different times of the year (e.g. emissions from home heating goes up in the cold winter months).  Still conditions often lead to high concentrations, as there is no wind to blow away the pollutants in the air.  The carbon monoxide concentrations are shown against the guidelines for air quality (hourly), and where concentrations exceed 100% of the guideline (red line) this can be a cause for concern, especially if this occurs on a frequent basis.
