how the accumulation of Hg POx and NOX affects the quality of H²O and living organsisms that live in rivers...

Question

lakes, and oceans

Answer 1

It severely affects the quality of the water. Mercury phosphates are very toxic to aquatic life and any animals who don't die immediately are tainted (like tuna). Nitrous oxides, I assume would also have a detrimental affect as NOx's are a big contributor in air pollution.
