Many red tides produce toxic chemicals that can affect both marine organisms and humans. The Florida red tide organism, K. brevis, produces brevetoxins that can affect the central nervous system of fish and other vertebrates, causing these animals to die. Keeping this in consideration, what are the harmful effects of red tide on man?
Coming into contact with toxic water Reactions to red tide may be worse in individuals with asthma, emphysema, or any other chronic lung disease. The toxins associated with red tide may also cause skin irritation, rashes, and burning or sore eyes.
Beside above, is it OK to swim in red tide? Swimming is safe for most people. However, the red tide can cause some people to suffer skin irritation and burning eyes. If you experience irritation, get out of the water and thoroughly wash off. Do not swim among dead fish because they can be associated with harmful bacteria.
Also Know, what is the red tide caused by?
Red tide is a phenomenon caused by algal blooms (Wikipedia definition) during which algae become so numerous that they discolor coastal waters (hence the name "red tide"). The algal bloom may also deplete oxygen in the waters and/or release toxins that may cause illness in humans and other animals.
How does the red tide affect the economy?
Many red tide and cyanobacteria blooms result in some type of economic impact. Health care costs from hospital and doctor visits, beach clean-up activities following fish kills, and losses in tourism revenues are some of the costs associated with these blooms.
