Dioxin analysis

[MLAP (Specific Measurement Certification System) Certification] We can conduct analyses for various media (ambient air, working environment, waste, and blood).

What are dioxins? Dioxins is a collective term that includes polychlorinated dibenzo-p-dioxins (PCDD), polychlorinated dibenzofurans (PCDF), and coplanar polychlorinated biphenyls (co-PCB). There are 75 types of PCDD, 135 types of PCDF, and 12 types of coplanar PCB isomers, each with varying toxicity. Toxicity of dioxins Among the 29 types of toxic dioxins, the toxicity varies for each. The most toxic, "2,3,7,8-tetrachlorodibenzo-p-dioxin," is assigned a value of 1, and the toxicity of other dioxins is expressed relatively in comparison. This relative coefficient is called the Toxicity Equivalence Factor (TEF). The analysis results are the sum of the toxic equivalents (TEQ) for each isomer, calculated by multiplying the measured concentration for each isomer by its Toxicity Equivalence Factor (TEF).
