This SAHSU study should be evaluated in the context of other work in this area.
Firstly, this is a study on PM10 whereas studies suggest that health issues are predominantly caused by PM2.5 and below, particularly the micro fines below PM1.
Secondly, it is surely stretching a point to suggest a study of a particular single issue can be applied to all other aspects of incinerator affects on health.
As an example "Air Pollution and Mortality in the Medicare Population" by Di et al published in 2017 in the New England Journal of Medicine shows a clear linear relationship between PM2.5 and increased mortality (figure 3) even below the WHO limit of 10 micrograms per cubic meter, in a sample size of 60 million medicare recipiants. Ii is beyond dispute that incinerators are a contributor to the overall air pollution burden.
