Reefton Air Quality Monitoring
PM10 is a measure of the amount of small particles in the air (smaller than 10 micrometers). These small particles tend to cause respiration problems at high concentrations. The National Environmental Standard for Air Quality (NESAQ) Guideline limit is a daily average of no more than 50 micrograms/m3 of PM10. An exceedance occurs when there has been an average of more than 50 micrograms/m3 of PM10 recorded over a 24 hour period. The NESAQ allows one exceedance per year. Wind strength and direction, as well as daily temperature variations, have a lot to do with the fluctuations in air quality.
There have been no exceedances of this standard in 2019.
