Revised December 22, 1999 law No. 160
June 9, 2004 law No. 94
Article 1 (purpose)
It is intended that we plan protection of health of the nation by this law setting basics of measure about dioxin and standard that you should do to do prevention of environmental pollution by dioxin and the removal taking dioxin being material which might have a serious influence on human life and health into consideration, and setting measures to modify necessary regulation, contaminated soil.
About value of 2 foregoing paragraphs, we shall perform necessary revision based on scientific knowledge while considering international trend about safe evaluation of chemical substance enough.
2 prefectural governors must report result of continuously monitoring of foregoing paragraph to the Minister of the Environment.
We investigate based on result of discussion of foregoing paragraph, and two and local public entity measure and shall send the result to prefectural governors.
3 prefectural governors shall announce result of as a result of the investigation measurement of Paragraph 1 and investigation into foregoing paragraph measurement that received sending by regulations.

Article 3 (conversion to the toxicity of 2,3,7,8-tetrachloride dibenzo - Para - dioxin)
We add up amount that takes advantage, and got coefficient to raise in the right column of the table every quantity of isomeric measurement to raise in column in the separate table third each and shall do conversion to the toxicity of 2.3,7,8- tetrachloride dibenzo - Para - dioxin prescribed in law Article 8 Paragraph 2 No. 1.
But we convert quantity of measurement of the isomers concerned as zero when there is when quantity of each isomeric measurement is less than the fixed-quantity lower limit.
