Totals may not correspond to the actual sum due to rounding off.
These are chemical substances which are used more than 0.1t on annual basis
*1 Amount of consumption=Total amount of discharged volume either as products or half-finished goods in addition to consumption in the processes (e.g. Those divided into different substances triggered by reaction in the production processes)
*2 Amount of eliminated consumption= The amount of consumption calculated by subtracting substances which impose impact on the environment by decomposition from the original
*3 Dichloromethane, trichloroethylene, and nickel compounds (including nickel sulfate) are subject to the survey on toxic air pollutant.
*4 Limited to those with number of carbons in alkyl base radical is 12 to 15 and their mixture.
