The limit is calculated as PCDD and PCDF according to the following toxic equivalency factors (TEFs):PCDDTEF2,3,7,8-TeCDD11,2,3,7,8-PeCDD11,2,3,4,7,8-HxCDD0,11,2,3,6,7,8-HxCDD0,11,2,3,7,8,9-HxCDD0,11,2,3,4,6,7,8-HpCDD0,01OCDD0,0003PCDFTEF2,3,7,8-TeCDF0,11,2,3,7,8-PeCDF0,032,3,4,7,8-PeCDF0,31,2,3,4,7,8-HxCDF0,11,2,3,6,7,8-HxCDF0,11,2,3,7,8,9-HxCDF0,1PCDDTEF2,3,4,6,7,8-HxCDF0,11,2,3,4,6,7,8-HpCDF0,011,2,3,4,7,8,9-HpCDF0,01OCDF0,0003’
PCDD ja PCDFi kontsentratsioonipiiride arvutamisel kasutatakse järgmisi toksilisuse ekvivalentfaktoreid (TEFid):PCDDTEF2,3,7,8-TeCDD11,2,3,7,8-PeCDD11,2,3,4,7,8-HxCDD0,11,2,3,6,7,8-HxCDD0,11,2,3,7,8,9-HxCDD0,11,2,3,4,6,7,8-HpCDD0,01OCDD0,0003PCDFTEF2,3,7,8-TeCDF0,11,2,3,7,8-PeCDF0,032,3,4,7,8-PeCDF0,31,2,3,4,7,8-HxCDF0,11,2,3,6,7,8-HxCDF0,11,2,3,7,8,9-HxCDF0,1PCDDTEF2,3,4,6,7,8-HxCDF0,11,2,3,4,6,7,8-HpCDF0,011,2,3,4,7,8,9-HpCDF0,01OCDF0,0003”
