Plunket AQ

Richmond is the largest urban area within Tasman District. It is located on the Waimea Plain adjoining Tasman Bay and Nelson City.

It has one monitoring site of PM10 and PM2.5.

Richmond has one air quality monitoring site located between commercial and residential land uses. The main state highway runs to the north west.

Air Quality Monitoring for Richmond began in 2000 with the current site established in 2006 when continuous monitoring of PM10 commenced. Monitoring of PM2.5 began at the site in October 2015 as daily measurements before changing to continuous monitoring in October 2018. From January 2021 both PM10 and PM2.5 are measured by a Thermo 5028i Beta Attenuation Monitor (BAM). All continuous monitoring is periodically benchmarked to measurements from a Thermo Partisol Monitor to maintain consistency of the dataset over time.

A meteorological monitoring station is located approximately 370 meters to the south east and a second meteorological monitoring site approximately 1350 meters to the north.

Since continuous monitoring commenced in 2006 PM10 exceedances have steadily reduced in number. In 2006 there were 35 days where PM10 was greater than 50 ug/m3. Over the last 5 years (2016-2020) the average number of exceedances of the 50 ug/m3 guideline has been 5 days. This has ranged from a low of 2 exceedances in 2017 to a high of 12 exceedances in 2018.

    What do the dashboard colours mean for PM10?

    The dashboard colours show how PM10 levels sit in relation to guidelines – from dark blue (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). 

    If a site has less than two days of PM10 exceedances each year, this is compliant with the NES-AQ.  If there are two or more exceedances annually, then the site does not comply with the NES-AQ.

    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 50 µg/m3.  

    The World Health Organization published new guidelines in September 2021 of 45 µg/m3 for daily averages and 15 µg/m3 for annual averages.

    What do the dashboard colours mean for PM2.5?

    The dashboard colours show how PM2.5 levels sit in relation to the guideline – from dark blue (less than 10%) to red (over the guideline).  The guideline (100%) value for  the daily average PM2.5 is 25 µg/mand 10 µg/m3 for the annual average.  There are no guidelines for hourly or monthly data (charcoal colour).

    If a site has less than four days of PM2.5 exceedances each year, this is compliant with World Health Organization 2005 guidelines.  If there are four or more exceedances annually, then the site does not comply with these guidelines.
