Description
本発明に係る水質評価方法の実施例1として、被試験水23は、2種類の河川水、水道水、および液肥を加えた水道水の4種類を用いた。2種類の河川水は、農業排水として田圃の横の小川から採取した河川水と、一般河川であってこの小川が流れ込む位置より下流側から採取した河川水とであり、どちらも夏期に採取した。尚、液肥は、ハイポネックス(発売元:ハイポネックスジャパン、チッソ6/リンサン10/カリ5)の1,000倍希釈液を被試験水23の一つとして用いた。
次に、実施例2として、家庭用洗剤を用いて上記実施例1と同様の方法により本発明に係る水質評価方法を用いた水質試験を行った。本水質試験に使用した洗剤は、商品名がソープルという洗剤(製造元:株式会社フェニックス)で、弱アルカリ性を呈し、成分は界面活性剤8%、脂肪酸カリウム14%、脂肪酸アルカノールアミド4%からなる。この家庭用洗剤に水道水を加えて濃度が、0%、0.01%、0.1%、および1.0%になるように調整して、被試験水23として用いた。
