Atmospheric pollutant measurements
  • For actual measured values, the highest measured values are shown.
  • For regulatory values, the strictest value from all relevant laws, ordinances and agreements is shown.
  • Regulatory value units
    NOx: ppm
    SOx: Sendai Plant use m³N/h, while all other bases use K values
    Soot and dust: g/m³N
    Dioxins: ng-TEQ/m³Nfor gas emissions
    Burnt residue: ng-TEQ/g
Water pollutant measurement
  • For regulatory values, the strictest value from all relevant laws, ordinances and agreements is shown.
  • Units are mg/L, except for pH and coliform bacteria, which is organisims/cm³
    pH: hydrogen ion concentration,
    BOD: biological oxygen demand,
    COD: chemical oxygen demand,
    SS: suspended solid concentration in water
Substances subject to the PRTR law
  • Units are given rounded to the nearest kg
  • The unit for dioxins is mg-TEQ/year with two significant digits
