Ammonia is toxic to aquatic life which leads to increased amounts of fish deaths. [6] Ammonia pollution also leads to eutrophication. Eutrophication is the growth of algae that kills other aquatic life and creates dead zones. Ammonia pollution affects freshwater and salt water ecosystems differently due to physical and chemical differences.
Combining bleach and ammonia creates a poisonous chloramine gas that can cause irritation and injury to the lungs. Here's what to do if you're exposed. Thousands of people accidentally mix ammonia ...
A purple sea urchin being tested for pollution using a whole effluent toxicity method.. Aquatic toxicology is the study of the effects of manufactured chemicals and other anthropogenic and natural materials and activities on aquatic organisms at various levels of organization, from subcellular through individual organisms to communities and ecosystems.

An ammonia test is the most sure way of diagnosing ammonia poisoning. Ammonia affects fish metabolism and their ability to absorb oxygen through their gills. This leads to a host of symptoms a few of which are: Purple, red or bleeding gills; Fish may clamp, may appear darker in color; Red streaking on the fins or body
Recirculating aquaculture systems (RAS) are used in home aquaria and for fish production where water exchange is limited and the use of biofiltration is required to reduce ammonia toxicity. [1] Other types of filtration and environmental control are often also necessary to maintain clean water and provide a suitable habitat for fish. [2]

Ammonium ions also have a toxic effect, especially on fish. The toxicity of ammonia is dependent on both pH and temperature and an added complexity is the buffering effect of the blood/water interface across the gill membrane which masks any additional toxicity over about pH 8.0. The management of river chemistry to avoid ecological damage is ...
A study in 2019 focused on linkages between water usage and animal agricultural practices in China. [52] The results of the study showed that water resources were being used primarily for animal agriculture; the highest categories were animal husbandry, agriculture, slaughtering and processing of meat, fisheries, and other foods.
