用法筆記

Often used in environmental, medical, and food-safety writing. The subject is typically a harmful substance (bacteria, chemicals, waste), and the object is something that people use or consume (water, food, soil, air, blood, equipment). Common in the passive: 'The area was contaminated with toxic waste.'

常見錯誤

The virus infected him after the bite.
'contaminate' usually applies to objects, substances, or environments (not living people or animals); use 'infect' for a living host that catches a disease.
