Some of the world's leading air quality and health experts are gathering in Newcastle next week to discuss the impacts of air pollution on people's health.

The Community Scientific Engagement Forum on air pollution and health will hear from some of the world's most eminent researchers and specialists on the subject.

Billed as the biggest gathering of its kind in New South Wales, the event is also being streamed live to communities in Muswellbrook and Gunnedah.

The Centre for Air Quality Health Research and Evaluation', Professor Guy Marks says there's accumulating evidence showing various pollutants have substantial impacts on health.

"Particularly on lung health and on cardiovascular health and those effects are evident even at relatively low levels of air pollution," he said.

"What that means is, is that there is benefit in continually attempting to further reduce the levels of air pollution."

A focus of discussion will be the contribution of coal mining and its associated activities on air quality, coupled with woodsmoke and other emission sources.

Professor Marks says it is about supporting research in the field of air pollution and its affects on health, then transforming it into policy.

"This conference is one of the activities that we're doing as part of that process.

"Particularly to make people aware of new developments in research on air pollution and health but also to listen to questions and formulate new questions in this field."
