Large　amounts　of　particulate　and　volatile　matter　derived　from　incense　burning　have　become　one　of　the　important　sources　of　indoor　air　pollution.　At　present,　the　research　about　the　effect　of　burning　incense　on　the　local　air　environment　mainly　focused　on　determining　particulate　matters,　volatile　gases,　and　organic　pollutants　after　incense　burning.　The　research　about　the　emission　efficiencies　and　emission　factors　of　heavy　metals　and　the　effect　of　particulate　heavy　metals　on　indoor　air　quality　after　incense　burning　has　not　been　reported.　To　better　understand　the　emission　characteristics　of　heavy　metals　in　Tibetan　incense,　nine　kinds　(S1S9)　of　line-type　Tibetan　incense　powder　samples　and　their　total　suspended　particulates　(TSP)　after　burning　were　digested　by　microwave　digestion　method　with　programmed　temperature　procedure,　and　four　primary　kinds　of　heavy　metal　elements　(i.e.　As,　Cd,　Cu,　Pb)　in　these　powder　samples.　Their　TSP　were　determined　by　the　inductively　coupled　plasma　optical　emission　spectrometry　(ICP-OES)　with　the　wavelength　188.980　nm　for　As,　214.439　nm　for　Cd,　327.395　nm　for　Cu　and　220.353　nm　for　Pb,　respectively.　The　experiment　results　are　listed　as　follows:　(1)　The　contents　of　four　heavy　metals　are　different　in　different　Tibetan　incense　samples,　and　the　average　content　of　heavy　metal　from　high　to　low　is　in　the　order　of　Cu,　Pb,　As　and　Cd.　The　source　of　Cd　and　Pb　in　different　Tibetan　incense　samples　is　similar,　remarkably　different　from　As　and　Cu.　(2)　After　burning,　the　amounts　of　smoke　and　dust　from　different　Tibetan　incense　samples　are　different.　The　largest　and　minimum　amounts　are　94.75　and　38.52　mg　center　dot　kg(-1),　respectively.　(3)　The　emission　amounts　of　As,　Cd　and　Pb　in　the　total　suspended　particles　from　different　Tibetan　incense　samples　depend　on　their　contents　in　the　incense　sample.　However,　the　emission　amount　of　Cu　is　not　only　dependent　on　the　incense　samples　but　also　affected　by　other　factors.　(4)　The　emission　efficiency　of　heavy　metals　in　Tibetan　incense　samples　from　high　to　low　is　in　the　order　of　Cd,　As,　Pb,　and　Cu.　The　emission　factor　from　high　to　low　is　in　the　order　of　As,　Pb,　Cd,　and　Cu.　(5)　The　emission　of　As　and　Cd　from　Tibetan　incense　samples　after　burning　may　adversely　affect　local　atmosphere　quality.　Among　these　samples,　the　highest　contents　of　As　and　Cd　in　the　TSP　of　S3,　S5　and　S9　from　the　same　manufacturer.　The　manufacturer　is　suggested　to　control　the　source　and　content　of　As　and　Cd　stricter　to　decrease　the　heavy　metal　pollution　in　indoor　air　and　the　risk　to　human　health　after　burning　Tibetan　incenses.
