What are the problems in estuaries?
Poor water quality affects most estuarine organisms, including commercially important fish and shellfish. The pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
What are other potential problems for the estuary?
Unfortunately, this increasing concentration of people is upsetting the natural balance of estuarine ecosystems and threatening their integrity. Pollution, habitat destruction, overfishing, wetland loss, and the introduction of non-indigenous species are among the consequences of many human activities.

How do humans in general threaten the intertidal zone?
Coastal pollution poses a threat to intertidal zones. Types of coastal pollution include discarded trash, oil spills, sewage spills, and toxic chemical runoff—all of which can negatively impact intertidal marine life.
Why do estuaries have high productivity?
Estuaries are one of the most productive ecosystems on earth. They maintain water quality through natural filtration as microbes break down organic matter and sediments bind pollutants. Water draining from the land carries sediments, nutrients, and other pollutants.
Do estuaries have salt water?
Estuaries are home to unique plant and animal communities that have adapted to brackish water—a mixture of fresh water draining from the land and salty seawater. The mixture of seawater and fresh water in estuaries is called brackish water and its salinity can range from 0.5 to 35 ppt.
