词源

From Middle English pollucioun, pollucion (“desecration, impurity”), from Anglo-Norman pollutiun, Middle French pollution, pollucion, and their source, post-classical Latin pollūtiō (“defilement, desecration; nocturnal emission”) (4th century), from the participial stem of polluō (“to soil, defile, contaminate”), from por- (“before”) + -luō (“to smear”), related to lutum (“mud”) and luēs (“filth”). Compare Ancient Greek λῦμα (lûma, “filth, dirt, disgrace”) and λῦμαξ (lûmax, “rubbish, refuse”), Old Irish loth (“mud, dirt”), Lithuanian lutynas (“pool, puddle”).
