Meaning
A substance, activity, or condition that poses a threat to the natural environment or to the health of living organisms within it.

Linguistics
Semantic Notes
A compound noun blending 'eco-' (ecology/environment) and 'hazard' (danger/risk). It specifically frames environmental threats through the lens of risk assessment and management. It is more technical than simpler terms like 'pollution' or 'danger to nature'.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'экохазард' – it is not standard. Use 'экологическая опасность', 'угроза экологии', or 'экологический риск'.
- Do not confuse with 'экологическая катастрофа' (ecological catastrophe) – an ecohazard is the potential cause, not the disaster itself.
Common Mistakes
- Misspelling as 'eco-hazard' (hyphenated form is less common in modern usage).
- Using it as a verb (e.g., 'to ecohazard' is incorrect).
- Confusing it with 'biohazard', which pertains specifically to risks from biological agents to human health.

FAQ
Frequently Asked Questions
Not exactly. 'Pollution' is the presence of harmful substances. An 'ecohazard' is the inherent dangerous potential of an agent or activity, which may cause pollution or other harm. All pollution is an ecohazard, but not all ecohazards have resulted in pollution yet (they are risks).
Yes. While often anthropogenic, natural events like volcanic eruptions (releasing ash and gases) or algal blooms can be classified as natural ecohazards due to their disruptive impact on ecosystems.
A biohazard (biological hazard) primarily refers to infectious agents or toxins that pose a risk to human or animal health. An ecohazard has a broader focus on threats to the overall environment and ecological balance, which can include chemical, physical, or biological agents.
No, it is a low-frequency, technical term. You will encounter it in specialised fields like environmental science, policy, and journalism, but it is unlikely to be used in everyday conversation.
