In this page, we speak the text in conjunction with the measurement of dioxin in environment in the Act on Special Measures concerning Countermeasures against Dioxins and the law enforcement regulations.

The Act on Special Measures concerning Countermeasures against Dioxins

July 16, 1999 law No. 105
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.

Article 2 (definition)
"Dioxin" is thing to raise next in this law.

(1) Polychlorinated dibenzo furan
(2) Polychlorinated dibenzo - Para - dioxin
(3) kopuranapori chlorinated biphenyl

Article 6 (tolerance daily intake)
It is chemical substance which dioxin produces with a person's activity and originally does intake (we say thing which we expressed for quantity of 2,3,7,8-tetrachloride dibenzo - Para - dioxin with intake that there is not fear to have an influence on health even if people took in dioxin for life continuously per day.) with value to set by cabinet ordinance in lower than 4 picograms per a person's 1 kilogram in weight on index of measure about dioxin which country and local public entity take taking not existing during environment into consideration and tolerance day when you should do.

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.

Article 7 (environmental standard)
The government atmospheric pollution by dioxin, contamination (include pollution of quality of bottom of the bottom.) of the quality of the water And, about condition on environment affecting pollution of the soil, what is maintained in protecting a person's health each shall set desirable standard.

Article 8 (effluent standard)
2
(1) Quantity (we say quantity that we partly converted to set quantity of dioxin kind measured by method to set in environmental departmental order of the toxicity of 2,3,7,8-tetrachloride dibenzo - Para - dioxin in environment departmental order.of dioxin included in exhaust gas It has the same as follows.) Maximum permissible level to be assigned to this, and to set

Article 26 (continuously monitor)
The atmosphere, the quality of the water (we include quality of bottom of the bottom.that prefectural governors are concerned with area of the metropolis and districts concerned It has the same as follows.) And you must continuously monitor the situation of pollution by dioxin of the soil.

2 prefectural governors must report result of continuously monitoring of foregoing paragraph to the Minister of the Environment.

Article 27 (the investigation measurement by prefectural governors)
Prefectural governors discuss with the head of local administration organization of country and the head of local public entity and shall measure investigation about the situation of pollution by the atmosphere, the quality of the water to affect area of the metropolis and districts concerned and dioxin of the soil.

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 42 (division of desk work)
Among desk work decided that prefectural governors handle by regulations of this law,……(omission)…… Thing decided to process does with the first legal trust desk work prescribed in Local Government Act (1947 law No. 67) Article 2 Paragraph 9 No. 1 by regulations of Article 26.

Departmental order No. 30 environmental on revised December 27, 2004
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.
