联想“contaminate（污染）”+“-ant（……的东西）”：被污染后混入的杂质，就像清水里滴入一滴墨水，那滴墨水就是contaminant。
Context & Register
语域：formal 常见场景：scientific reports、environmental regulations、food safety bulletins contaminant 通常用于正式或科技语境，如环境科学、食品安全和实验室报告；日常口语中较少见，更常用 pollutant 或 impurity。
Pronunciation & Spelling
这些词末尾大多含有 /mɪnənt/（dominant、prominent、imminent、eminent、ruminant），但重音元音不同，所以它们与 contaminant 并不真正押韵；只有 contaminant 的重音在第二个音节 /ˈtæm/。注意 permanent 是形近词，读作 /ˈpɜːrmənənt/，不要读成 /ˈpɜːrmɪnənt/。
