Kontaminoidun

Kontaminoidun is an Estonian adjective used to describe something that has become contaminated. It is commonly found in scientific, environmental, and health-safety contexts to indicate that a material, area, or object bears hazardous substances, contaminants, or pathogens. The form is derived from the verb kontamineerida (to contaminate) via a past passive participle construction, conveying a completed state of contamination.

In use, kontaminoidun signals risk and the need for corrective action. It appears in safety reports, environmental assessments, and medical documentation to document contaminated settings, equipment, or samples. The term is relatively specialized and more common in formal Estonian than in everyday speech.

Related terms include kontaminatsioon (contamination) and kontamineerima (to contaminate). The concept covers chemical, biological, radiological, and other forms of contamination, and it often pairs with remedial or decontamination steps in context. For example, authorities might classify a site or item as kontaminoidun following exposure to hazardous agents, triggering procedures to isolate, decontaminate, or dispose of affected materials.
