Editing Polychlorinated dibenzodioxins (section)

==Dioxin testing==
The analyses used to determine these compounds' relative toxicity share common elements that differ from methods used for more traditional analytical determinations. The preferred methods for dioxins and related analyses use high resolution gas chromatography/mass spectrometry (HRGC/HRMS). Concentrations are determined by measuring the ratio of the analyte to the appropriate isotopically labeled internal standard.<ref>[http://www.epa.gov/fem/methcollectns.htm Method Collections | Measurement Science | Office of the Science Advisor | US EPA].

Also novel bio-assays like [[DR CALUX]] are nowadays used in identification of dioxins and dioxin-like compounds. The advantage in respect to HRGC/HRMS is that it is able to scan many samples at lower costs. Also it is able to detect all compounds that interact with the Ah-receptor which is responsible for carcinogenic effects.<ref>{{cite web|last=Behnisch|first=Peter|title=Internation-Dairy.com|url=http://www.bds.nl/1/doc/Dioxins%20%26%20Robotics.pdf|access-date=18 April 2014|url-status=dead|archive-url=https://web.archive.org/web/20140418220702/http://www.bds.nl/1/doc/Dioxins%20%26%20Robotics.pdf|archive-date=18 April 2014}}</ref>
