1. air pollution: after ethanol leaks, ethanol vapor will be formed in the air, which will make people suffocate, faint or be poisoned, especially in a closed environment.
2. Water pollution: The leakage of ethanol will pollute groundwater, rivers, lakes and other water sources. Ethanol is an organic substance, which can be decomposed by microorganisms, but in this process, it will consume oxygen in water, leading to the death of aquatic organisms.
3. Soil pollution: The leakage of ethanol into soil will lead to soil pollution and affect the health of soil ecosystem.
