Some chemicals are toxic at elevated levels (such as ammonia) and can cause mortality to fish populations, the majority are not at levels that increase mortality but they do encourage the growth of algae and other plant growth in the water. When the algae dies it decomposes using up the oxygen in the water - killing the fish. This process is called eutrophication (enriching) of the water ecosystem.
