The environment in urbanized areas is often contaminated with a complex mixture of toxic compounds like polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (dioxins like PCBs). They are structurally related chemicals and persist in the environment and accumulate in organisms. They are often collectively referred to as “dioxins” because of their similar structures, chemical properties and mechanism of action in biological systems.

Most widely used method to determine the dioxin concentrations are as follows:

1. Analytical Method:
High-Resolution Gas Chromatography-High Resolution Mass Spectrometry (HRGC-HRMS)

2. Screening Method:
CALUX Bioassay- This is a reporter gene assay, which detects dioxin and dioxin-like compounds based on their activation of the aryl hydrocarbon receptor (AhR), which increases expression of the luciferase reporter gene.

Approved as an Official Method

EU Directive in 2002.
Ministry of the Environment, Japan 2005.
EPA Method 4435 in 2007.
Japanese Industrial Standard Method – JIS K0463 in 2009.
Taiwan EPA Soil Standard Screening Method NIEA S90160B in 2010.

Merits of HighLux Bioassay

High precision, short turn-around and inexpensive.
Faster and cheaper than traditional method (HRGC/HRMS).
HighLux Bioassay can be used for Dioxin screening of wide variety of environmental matrices such as soil, sediment, ash, water, exhaust gas as well as low concentration matrix such as food/biological samples.
