Obligation for POPs: stop of use by 2025 and the completion of disposal by 2028!!
POPs mean Persistent Organic Pollutants which is the generic term for the chemical substances with high persistence, bioaccumulation, and transfer and diffusion in environments. - The Convention on POPs became effective in May 2004. -
The Convention on POPs (Stockholm Convention) prohibits the manufacture and the use of POPs, and limits their emission.
In Japan, the manufacture, the import, and the use of the substances indicated as POPs (excluding the dioxins which are unintentional products) are prohibited by the Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture, etc. (Chemical Substances Control Law), the Agricultural Chemicals Control Act, etc. For unintentional products such as the dioxins generated by waste incineration, etc., the emission is regulated according to the Act on Special Measures concerning Countermeasures against Dioxins.

Hexachlorobenzene (HCB) had been used as a fungicide, etc., but was designated as the Class 1 Specified Chemical Substance in 1979, and its manufacture, selling, and use are prohibited. It is also designated as POPs (Persistent Organic Pollutants), and the stop of use by 2025 and the completion of disposal by 2028 are obliged (according to the Convention on POPs).
Furthermore, in Action for by-product of hexachlorobenzene which is the Class 1 Specified Chemical Substance specified in the Chemical Substances Control Law (http://www.env.go.jp/press/press.php?serial=6955) released by the Ministry of the Environment, the case example where the by-product of HCB was obtained in the synthesis process of tetrachlorophthalic anhydrite (TCPA) was reported.
We conduct the analysis of HCB in emission gas, dust, etc. Please consult us regarding other media.
