What about:
http://erj.ersjournals.com/content/24/6/1069.shortThese are locked (for non-students) by my uni but there are a bunch:
-A Case–Referent Study of Lung Cancer and Incense Smoke, Smoking, and Residential Radon in Chinese Men (2011)
-Soot-driven reactive oxygen species formation from incense burning (2011)
-Characterization of emissions from burning incense (2002)
-Characteritization of, and health risks from, polychlorinated dibenzo-p-dioxins/dibenzofurans from incense burned in a temple (2009)
Hope that helps!
