How many liters of water can one cigarette butt pollute?

One cigarette butt can pollute up to 1,000 liters of water, according to OceanCare.
Most environmental sources agree that the average impact is around 500 liters per cigarette.

Why? Because cigarette filters contain over 7,000 toxic substances, including nicotine, heavy metals, and microplastics.
These harmful chemicals leach into the water and pose a real threat to aquatic ecosystems.

Some studies show that just one cigarette butt in a single liter of water can kill 50% of exposed fish within 96 hours.
