Dioxins & Furans

Chlorinated dioxins and furans are  persistent, bioaccumulative and toxic organic pollutants listed in the Stockholm Convention. SGS AXYS has conducted dioxin analysis since 1989 and continues to lead in this measurement. In 1996, SGS AXYS was one of a small handful of laboratories to meet the criteria of a World Health Organization study of human plasma and milk analysis for chlorinated dioxins/furans and dioxin-like PCBs.  Our stable of 8 GC-HRMS and GC-MS/MS systems provides large capacity and flexibility.

  • We offer accredited analysis GC-HRMS and GC-MS/MS (new) for 2,3,7,8-substituted chlorinated dioxins and furans, TEQs and totals in all environmental, biota and human matrices for a comprehensive testing solution
  • Our experience and data quality framework provide data of unparalleled defensibility for high-importance litigation and remediation projects
  • Coextractions and sophisticated multiplexing with PCBs, pesticides and more can generate 100s of POP measurements at low detection limits from a single, limited sample
  • We raise the bar on product leadership: In collaboration with the US-EPA, we recently validated and benchmarked GC-MS/MS techniques for EPA 1613B-equivalent performance and future-proofing. An alternate method (ATP) with the US-EPA is in progress.

Application Spotlight

SGS AXYS has supported the remediation of sites contaminated with Agent Orange in Vietnam for many years. In this study, we helped researchers Pham et al. 2018) measure and predict dioxin levels in people living in Da Nang and Bien Hoa years after the exposure. They used this data, existing measurements done in fish in the area (much of this work was also done by SGS AXYS) and other factors to predict that the consumption of fish from contaminated sites was likely the most significant current source of contamination in people.
