Why can't we destroy bothersome pollutants by just dissolving in ocean

Bothersome pollutants are pollutants that persist in water.

Explanation:

Bothersome pollutants are those pollutants that have deleterious effects on human health which are consistently lodged into water bodies. Bothersome pollutants include petroleum products, heavy metals, and toxic chemicals etc.

Many of these bothersome pollutants are non biodegradable. They accumulate at the bottom of the ocean thereby causing problems for aquatic organisms and disrupting the aquatic ecosystems in the ocean.

These bothersome pollutants are not soluble in water hence we can not just destroy them by dissolving them in water. They persist in the aquatic ecosystem and can even migrate from place to place thereby spreading pollution.
