Neurotoxic Shellfish Poisoning
Erica Cheries & Claire Ingram
1. What Causes a Dead Zone
2. What Types of Organisms are involved?
The organisms that make the concentration of oxygen dangerously low are a type of algae called Karenia brevis and they also create brevetoxins a toxin which contaminates shellfish. Brevetoxins can accumulate in shellfish when they are exposed to these dead zones which then affect humans who harvest shellfish from these dead zone areas. Illnesses within humans result from eating contaminated shellfish that has been harvested from an area with these Karenia Brevis and brevetoxins in the water.
3.What are the ecological impacts, which species are affected and how is the environment affected?
The ecological impacts can be very large. Beaches may close, species begin to die off, humans begin having health effects if they have eaten something affected or been in the water affected or even inhaling the air near the toxins.
4. What are the economic impacts?
6. What can be done to reduce, eliminate, or manage access nutrients and solve this issue?
