The carrier effect mechanism of butachlor in water by three typical microplastics [PDF]
Environmental Science and Pollution Research, 2022 Butachlor (BUT) is a widely used herbicide that can cause environmental problems when used excessively. BUT has been found to exist in large quantities in the water environment so far. As an agricultural pre-emergent herbicide, BUT can enter the water environment through multiple channels and cause pollution.

Photodecomposition of a Herbicide, Butachlor
Journal of Pesticide Science, 1978 除草剤ブタクロール (マーシェット) をガラス上で薄膜状にして紫外線を用いて光分解を行なった結果, 分解は比較的速やかに進行し, 実験条件下で半減期は約1.5時間であった. TlcおよびGlcによる分析では少なくとも7種の分解生成物の存在を認めることができた. その中で2-chloro-2′,6′-diethylacetanilide の存在を標準品との比較によって確認し, 2-hydroxy-2′,6′-diethyl-N-(butoxymethyl)acetanilide, 1-chloroacetyl-2,3-dihydro-7-ethylindole およびN-2′,6′-diethylphenyl-2,5-dihydrooxazol-4-one の三化合物の存在をIRおよびGC ...

Summary of Toxicology Studies with Butachlor
Journal of Pesticide Science, 2000 ブタクロールは, 米国モンサント・カンパニーが開発した一年生イネ科雑草および一部の広葉雑草を対象とする稲作用除草剤である. 動物実験の結果, 本剤の哺乳動物に対する急性経口, 経皮, 吸入毒性はいずれも軽微で, 眼および皮膚一次刺激性は低い. モルモットを用いた皮膚感作性試験において陽性の反応が認められた. 亜急性および慢性毒性試験の結果, 主として肝臓および腎臓に検体投与による影響が認められたが, これらの影響には閾値が存在した. ラットを用いた慢性毒性/発がん性併合試験において腺胃, 鼻部および甲状腺の腫瘍が認められたが, 腫瘍発生のメカニズムに関する試験研究の結果, これらの腫瘍は閾値の存在する非遺伝子傷害性の作用によって引き起こされていることが解明されている ...
