St Albans

St Albans is where the longest record of air monitoring exists in Christchurch. This site in Coles Place was established in late 1998, when the future of the Packe Street site was uncertain. These two St Albans sites ran in parallel for a few years, and the combination can be used to assess long term trends back to 1988. Of the seven LAWA indicators that have been measured at this site, only PM10 and PM2.5 currently exceed guidelines.

PM2.5 monitoring was carried out in 2005, then started again in 2011. Carbon monoxide and nitrogen dioxide have exceeded their guidelines in the past, but their concentrations have been decreasing over time. Sulphur dioxide has never exceeded its guidelines, and concentrations have also been decreasing over time. Ozone monitoring started in 2012 until April 2017, and all concentrations have been below their guidelines. Benzene has been monitored during three years (2001, 2004, 2008), did not exceed the annual guideline in 2004 nor in 2008, and has decreased over this time.

    What do the dashboard colours mean for PM10?

    The dashboard colours show how PM10 levels sit in relation to the guideline – from green (less than 10%) to red (more than 100% of the guideline).  The guideline (100%) value for the daily average PM10 is 50 µg/m3 and  20 µg/m3  for the annual average.  There are no guidelines for hourly or monthly data (charcoal colour).

    What is this graph showing me?

    This graph shows how levels of PM10 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 PM10 concentrations are shown against the guidelines for air quality (for daily and annual averages), and where concentrations exceed 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 days per year that the concentrations went above 100% of the air quality guideline.
