NL、MOLおよびグルタルアルデヒドについて、経口毒性の測定、藻類への毒性試験、汚泥への殺菌性試験、生分解性試験を行った。試験方法と結果は以下のとおりである。
2%-アラビアゴム水溶液(0.5%-Tween80を含む)に乳化分散させた被験物質を、6週令の雄性CRj:CD(SD)ラットに経口ゾンデを用い1日1回14日間強制的に投与した。投与期間中の体重変動および一般状態を観察した。最終投与日より1日間絶食し(飲水は自由摂取)、最終投与の翌日に解剖、採血(各種血液検査)、主要臓器の質量測定を行った。また、肝・腎・脾臓・精巣については病理組織学的な検査(HE染色薄切切片の光学顕微鏡観察)も実施した。投与量は1000、250、60、15、0mg/kg/day(投与液量=1ml/100g(体重)/day)で、各用量につき5匹を用いた。
被験物質:
(1)NL(GC純度:99.7%)
(2)グルタルアルデヒド(含水量101ppm、GC純度:99.8%)
試験の結果、NLについては最高投与量1000mg/kg/dayでも死亡例は認められなかった。NLは「劇物」には該当しない。本試験条件での最大無作用量(NOEL)を表1に示す。
OECDテストガイドラインNo.201を参考に被験物質の藻類生長阻害試験を実施した。すなわち、以下の被験物質を試験培地で希釈し規定の用量とした。前培養により指数増殖期まで生長させた藻類の懸濁液を初期濃度1×104cells/mlとなるよう添加した。光照射型のバイオシェーカー(TAITEC製 Bio Shaker BR-180LF)で23℃にて振とう培養し、試験開始から24、48、72時間後の藻類細胞をフローサイトメーター(BECKMAN COULTER製 Cell Lab Quant SC)で計数し、正常対照の生長度を100%として各試験用量の生長度を算出した。また、生長阻害率をプロットしたグラフの近似曲線の方程式よりErC50を算出した。標準物質として二クロム酸カリウムを用いた。
藻類:Pseudokirchneriella subcapitata
被験物質:
(1)NLとMOLの混合物(GC純度:98.7%、NL/MOL=59/41)
(2)グルタルアルデヒド(含水量101ppm、GC純度:99.8%)
被験物質用量:
被験物質(1)、被験物質(2)各々について、それぞれ100、32、10、3.2、1、0.32mg/L(公比:√10)及び0mg/L(正常対照)
標準物質:3.2、1、0.32mg/L及び0mg/L(正常対照)
本試験における二クロム酸カリウム(標準物質)の72時間後のErC50は1.3mg/Lであり、正常対照の72時間後の生長率は93.0%であったことから、本試験は正常に稼働したと判断した。試験結果を表2に示す。
グルコース、ペプトン、リン酸二水素一カリウム各々5gを水1リットルに溶解させ、水酸化ナトリウムでpHを7.0±1.0に調整した合成下水に、日本国岡山県倉敷市水島地区の下水処理場の汚泥を乾燥質量換算で30ppmとなるように添加して菌液を調製した。一方、24wellのマイクロプレート上で、被験物質が最終濃度で1000~0.004ppm(公比=4)となるように蒸留水で10段階希釈したものを試験液とした。各濃度毎に2wellを使用した。比較対象としては、蒸留水+菌液を“菌液ブランク”、蒸留水のみを“ブランク”とした。
上記で調製した菌液と試験液を容量比1:1で混合し、常温(約25℃)の恒温槽内で24時間および48時間静置し、それぞれMTT法を用いて被験物質の各濃度における汚泥影響度を目視確認した。なお、MTT試薬は汚泥中微生物のミトコンドリアで変換され、フォルマザンを形成し青色を呈する。微生物が死滅した場合には同反応が起こらず、黄色を呈する。
被験物質:
(1)NLとMOLの混合物(GC純度:98.7%、NL/MOL=59/41)
(2)グルタルアルデヒド(含水量101ppm、GC純度:99.8%)
結果を表3に示す。
OECDテストガイドライン301C、JIS K 6950(ISO 14851)の試験方法を参考に被験物質の分解度試験を実施した。すなわち、培養ボトルに無機培地液300ml、日本国岡山県倉敷市水島地区の水島下水処理場より試験開始当日入手した活性汚泥9mg(30ppm)を入れ、被験物質は共に殺菌作用があることから汚泥への影響を加味して高濃度群:被験物質30mg(100ppm)、および低濃度群:9mg(30ppm)の2濃度で生分解性試験を実施した。
被験物質:
(1)NLとMOLの混合物(GC純度:98.7%、NL/MOL=59/41)
(2)グルタルアルデヒド(含水量101ppm、GC純度:99.8%)
クーロメーター(大倉電気3001A型)を用いて25℃で28日間培養し、被験物質の分解に消費された酸素量と被験物質の構造式より求めた理論酸素要求量を用いて生分解率を算出した。生分解標準物質としてはアニリン30mg(100ppm)を用いた。生分解率が60%以上の時、良分解性物質と判定した。被験物質の評価数はn=2とした。
NL/MOL高濃度群(100ppm)の28日間の生分解率はそれぞれ88.4%、86.8%(平均:87.6%)であり、『良分解性』と判断された。
NL/MOL低濃度群(30ppm)の28日間の生分解率はそれぞれ100.3%、97.3%(平均:98.8%)であり、『良分解性』と判断された。
グルタルアルデヒド高濃度群(100ppm)の28日間の生分解率はそれぞれ52.7%、52.5%(平均:52.6%)であり、『部分的な生分解性(難分解性)』と判断された。
グルタルアルデヒド低濃度群(30ppm)の28日間の生分解率はそれぞれ78.5%、77.5%(平均:78.0%)であり、『良分解性』と判断された。
従って、NLおよび/またはMOLは、グルタルアルデヒドに比べ、環境・労働安全上、安全性が高いことが示された。
<熱安定性試験>
以下の試験液をそれぞれバイアル瓶に入れ、空隙部を窒素置換し、密封したものを60℃で保管し、保管開始直後の各試験液におけるNL/MOL、またはグルタルアルデヒド含有量を100%とした際の5日後、12日後、21日後の含有量の変化を、内部標準を用いたガスクロマトグラフィーによる検量線法で観察した。結果を表4に示す。
試験液1:NLおよびMOLの混合物(質量比:92/8)
試験液2:NL/MOL/水=91:7:2(質量比)の混合物
試験液3:50%グルタルアルデヒド水溶液(東京化成工業株式会社製)
