O. Reg. 419/05, s. 1 (2); O. Reg. 112/07, s. 1 (3). (2.0.1) For the purposes of this Regulation, an amount (or concentration) of a metal’s compounds is the sum of the amounts (or concentrations) of that metal in those compounds.  O. Reg. 282/11, s. 1 (2). (2.0.2) For the purposes of this Regulation, an amount (or concentration) of dioxins, furans and dioxin-like PCBs shall be calculated in accordance with the following rules: 1. For each contaminant listed in Schedule 8, calculate the Toxicity Equivalent (TEQ) by multiplying the amount (or concentration) of the contaminant by the Toxic Equivalency Factor set out opposite the contaminant in that Schedule. 2. The amount (or concentration) of dioxins, furans and dioxin-like PCBs is the sum of all the Toxicity Equivalents calculated under paragraph 1.  O. Reg. 282/11, s. 1 (3). (2.1) References in this Regulation to mercaptans are expressed as methyl mercaptan and, for the purposes of this Regulation, an amount (or concentration) of total mercaptans shall be calculated in accordance with the following formula: A =  ((B × 48) ÷ C) where, A = the amount (or concentration) of total mercaptans, B = the amount (or concentration) of each mercaptan, C = the molecular weight of each mercaptan.
