are any of these blooms harmful?
Yes -Improper harvesting of shellfish can cause paralytic shellfish poisoning and neurotoxic shellfish poisoning in humans. Some symptoms include drowsiness, diarrhea, nausea, loss of motor control etc. Reports of skin irritation after swimming in the ocean during a red tide are common
Red tide
In most cases like in the U.S., the seafood consumed by humans is tested regularly for toxins by the USDA to ensure safe consumption. However, improper harvesting of shellfish can cause paralytic shellfish poisoning and neurotoxic shellfish poisoning in humans. Some symptoms include drowsiness, diarrhea, nausea, loss of motor control, tingling, numbing or aching of extremities, incoherence, and respiratory paralysis. Reports of skin irritation after swimming in the ocean during a red tide are common, so people should try to avoid the red tide when it is in the area.

When the red tide cells rupture, they release extracellular brevetoxins into the environment. Some of those stay in the ocean, while other particles get aerosolized. During onshore winds, brevetoxins can become aerosolized by bubble-mediated transport, causing respiratory irritation, bronchoconstriction, coughing, and wheezing, among other symptoms. On a windy day, avoiding contact with the aerosolized toxin is recommended
when does the rainy season end in south florida October is the climate there related to africa? Dust from the Sahara desert in Africa moves into the state of Florida due to the trade winds is there any particular season of cyclones? Mainly happens between August and October what is the reason? La Niña has the following effects: often dry conditions prevail in late fall, winter and early spring, increased risk of wildfires in spring and summer months, the temperatures average slightly above normal, and the chance of hurricane activity increases substantially. is this phenomenon which results in these effects a river or a stream? UNANSWERABLE are there different types of climates in different cities of the state? Orlando and Jacksonville receives between 2,400 and 2,800 hours of sunshine annually. The rest of the state, including Miami, receives between 2,800 and 3,200 hours annually. which environmental problems are there in the state? Red tide is now killing off wildlife or Tropical fish and coral reefs putting all in danger. what is this tide? A common name for algal blooms, which are large concentrations of aquatic microorganisms, such as protozoans and unicellular algae. what are the contributing factors to it? The upwelling of nutrients from the sea floor, often following massive storms, provides for the algae and triggers bloom events. does this kind of bloom occur in fresh water? No - they cannot thrive in freshwater environments. how are they characterized? Certain species of phytoplankton and dinoflagellates like 'Gonyaulax' found in red tides contain photosynthetic pigments that vary in color from brown to red. These organisms undergo such rapid multiplication that they make the sea appear red.The production of natural toxins such as brevetoxins and ichthyotoxins are harmful to marine life.

Red tide [SEP] Human exposure
Humans are affected by the red tide species by ingesting improperly harvested shellfish, breathing in aerosolized brevetoxins (i.e. PbTx or "Ptychodiscus" toxins) and in some cases skin contact. The brevetoxins bind to voltage-gated sodium channels, important structures of cell membranes. Binding results in persistent activation of nerve cells, which interferes with neural transmission leading to health problems. These toxins are created within the unicellular organism, or as a metabolic product. The two major types of brevetoxin compounds have similar but distinct backbone structures. PbTx-2 is the primary intracellular brevetoxin produced by "K. brevis" blooms. However, over time, the PbTx-2 brevetoxin can be converted to PbTx-3 through metabolic changes.
