PM10 is emitted from the combustion of fuels, such as wood and coal (from home heating and industry) and petrol and diesel from vehicles. Natural sources such as volcanoes, wind-blown dust, and sea salt can also produce PM10.
The contaminant is also formed in the air from reactions between gases or between gases and other particles.
"We hope publishing this monitoring data on LAWA will help grow awareness and understanding of air quality issues and the work we do to keep our air clean and free of pollution," Mr Iremonger said.
This work includes identifying the most significant air quality issues in the Bay of Plenty.
The council released a draft Regional Air Plan in April that outlines the issues in detail and proposes solutions to address them. There have been a series of public workshops, liaison with industry and various advertising to ensure public have input into this draft plan. Feedback is still welcome, and people have until close of business tomorrow (Friday June 17th) to provide input.
