The main topic in South East right now is the contamination of  dioxins in 
food imported from Europe. We have difficulties in  finding the method for 
determination dioxins in food or diary  milk. Would you help me? 

EPA methods 1613 or 8290 may be used.  These methods use high resolution 
gas chromatograpy/mass spectroscopy.  Copies of the methods may be 
obtained from EPA. http://www.epa.gov/ncepihom/catalog.html http://www.epa.gov/epahome/publications.htm
If you know the likely source of the dioxins were PCBs, testing for PCBs 
(~$50), instead of for dioxin ($1000+) would be cheaper.  Good luck
