NOTE :

  1. Figures are 24-hour average concentrations on the day of sampling in pg I-TEQ /m3.
  2. The concentration of dioxins is expressed as toxic equivalent (I-TEQ) concentration of 2,3,7,8 - Tetrachlorodibenzodioxin (TCDD) based on the International Toxic Equivalent Factors (I-TEF) of the North Atlantic Treaty Organization (NATO/CCMS)
  3. For congener concentrations that are lower than the estimated minimum sample detectable level (EMSDL), one half of the EMSDL is used in calculating the I-TEQ concentration
