行われた。Over a period of one year from April 1981 to March 1982, the analysis team of the Liaison Committee for Water Diversion and Water Issues conducted an investigation of the Triphalomentha content in tap water sampled from diversion faucets.
その結果、流用の上流に比べて、下流の採水地点はど、
トリフアロメタンの数値が高くなっていることが判明し
た。As a result, compared to the upstream of the diversion, the downstream water sampling point is
It was found that the levels of trifluoromethane were elevated.
このことは、上流の浄水場から採水地点までの距離と、
トリフアロメタン含有値が比例することを示している。This depends on the distance from the upstream water treatment plant to the water sampling point,
It is shown that the triphalomethane content value is proportional.
即ち、水道水中の塩素とフミンとの接触時間が長いほど
、トリフアロメタンが多く生成されるわけである。That is, the longer the contact time between chlorine and humins in tap water, the more trifluoromethane is produced.

記のように塩素とフミンが反応してトリフアロメタンが
生成される。Therefore, when tap water is used at a point far from a water treatment plant, chlorine and humin react as described above and trifluoromethane is produced during the long journey from the water treatment plant to the point of use.
従って、このような水道水を飲み続けるうちに、人間の
体内に次第にトリフアロメタンが蓄積し、人体に害を及
ぼすおそれがある。Therefore, as people continue to drink such tap water, trifluoromethane gradually accumulates in the human body, which may cause harm to the human body.
