contamination
意味: The action or state of making something impure by exposure to or addition of a poisonous or polluting substance.
Contamination applies to water, soil, air, food, and even data or evidence. Environmental contamination from industrial processes is a major public health concern. The term also appears in laboratory and forensic contexts, where contamination of samples can invalidate results. Cross-contamination is a specific concern in food safety and healthcare settings.
