St Johns

The St John’s College site in Mahora, Hastings was established in 2006. PM10 and PM2.5 from home heating are the main pollutants monitored in this residential area.

The St John’s College site was chosen as it is a typical residential area with average road traffic. The air shed includes the city suburbs plus Clive (on the coast), Flaxmere, Havelock North and the rural areas in between. The Hastings airshed must fully comply with the NES from 2020.

Scientific Indicators
Scientific data for this site

This dashboard shows the latest results for air quality indicators collected by regional councils and unitary authorities.  Indicators are shown against the National Environmental Standards for Air Quality (NES-AQ).  Where no national standards exist for the air quality measurements shown, the data are compared against other guidelines (e.g. World Health Organization (WHO) 2021 guidelines, Ambient Air Quality Guidelines (AAQG)).

    What is this graph showing me?

    This graph shows how concentrations of PM10 change on an hourly, daily, monthly or annual basis for the selected time period. The number of exceedance days can be viewed over the last 10 years or all years if available.

    The PM10 daily average concentrations and exceedance days are compared to the National Standard (NES-AQ), and the PM10 annual average concentrations are compared to the WHO guideline.  The standard and guideline limits are denoted by the red horizontal line.   There are no guidelines for hourly or monthly average concentrations.  For information about allowable exceedances and targets, and the limitations of data shown, see the factsheet on monitoring air quality in New Zealand. 

    The concentrations depend on local sources of emissions and weather conditions. 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 go 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.  At some monitoring sites, the hourly temperature and wind data are available to explore the relationship between local weather conditions and PM10 concentrations.  See this factsheet about why air quality is important and factors that influence air quality.
