Please note: This site was closed on the 3rd of April 2013 to enable monitoring in another airshed to take place.
This disestablishment of monitoring sites where three years of monitoring has indicated no exceedances of the NES is part of an ongoing monitoring strategy to re-deploy monitoring equipment in airsheds where air quality has not yet been monitored.
The information on this page is provisional, and has not been checked using the council's quality assurance procedures. Please note that the three day PM10 graph is a point-in-time measurement and not directly comparable to the national environmental standard for PM10, which is based on a 24 hour average.
Waikato Regional Council monitors fine particle (PM10) levels in the air. The majority of PM10 in the Waikato comes from home fires, mainly from burning wood. PM10 can cause respiratory problems, especially for asthmatics, children and the elderly, and can result in hospital admissions and premature mortality in sensitive people. The National Environmental Standard for air quality requires that there is no more than one exceedance per year of the PM10 threshold of 50µg m-3 as a 24 hour average.
