It says that in the 1974 arbitration, the mining pollution issues were 'ended' (from "History of 100 Years of Business from Foundation") and yet, it is not mentioned that Furukawa Mining had not admitted their responsibility for contamination by cadmium (it does not mention the Agreement of Pollution Control made in 1976 either, however this literature was published in the same year as the agreement was made, and they might not have been able to include it in the editing process.)
1974年の調停で、鉱毒問題については「終止符が打たれた」（『創業100年史』より）と述べているが、古河鉱業がカドミウム汚染に関する責任を認めていないことについての言及はない（1976年に結ばれた公害防止協定への言及もないが、協定成立年とこの文献の発行年が同年であることから、編集に間に合わなかったという可能性もある）。
