Anoxia: Oxygen deficiency in environmental locations such as sediments and bodies of water.
Anthropogenic: Human influences on the environment.
Effluents: Water discharged from one source into a separate body of water.
Endocrine disrupters: Pollutants that enter the environment that have molecular similarity to animal hormones and can disrupt the animal's endocrine system.
Euryhaline: Organisms with the capacity to live within a wide range of water salinity.
Euthropication: The process by which increased levels of nutrients enter a body of water.
