eutrophication in China is really serious. One of the most famous ones is the Tai River blue-green algae in 2007. Because of the eruption of blue-green algae‚ the water can’t be used at all. It smells like something is becoming putrid. Also some algal blooms are toxic to plants and animals. It has affected the citizen’s lives; they can just drink and use the water which was brought in shops. The urgent demand of the water has caused the price of the water to became more and more expensive. (Face to

5.Explain how a Harmful Algal Bloom can impact an ecosystem. The toxins can be spread throughout various organisms as of humans and the food chain. If the consistent blooms it can block the light from reaching into the water and it can cause many organisms dead. 6.Create a chart or Graph showing the estimated economic impact of HABs on the United States over three years.

Are Dinoflagellates?”). Uniquely‚ dinoflagellates have two flagella. One flagellum is around the cell‚ and the other directed to the back. They contain chlorophyll a and c‚ as well as other carotenoid and xanthophyll pigments. When dinoflagellates bloom‚ or overpopulate‚ they tend to change the water to a reddish brown color. Dinoflagellata are sometimes called Pyrrhophyta‚ meaning "fire plants". This is because some species are capable of bioluminescence‚ in which chemicals made by the organism produce

forms the base of food chain in most water bodies. Among these phytoplankton groups‚ there are some species that harm aquatic organisms mechanically or by toxin production either at low concentrations or by forming high concentration blooms known as Harmful Algal Blooms (HABs). When doing aquaculture in natural water bodies like lakes‚ rivers and oceans‚ these harmful plankton could seriously damage the stock. So‚ monitoring for harmful plankton species is required. Harmful plankton monitoring is

enormous growth in algae populations‚ literally choking the life out of aquatic ecosystems and polluting water for humans as well. These “Harmful Algal Blooms” (HAB’s) or green tides as some call them can produce toxins that can hurt animals and humans alike turn water green and can cover miles of water in a single bloom. (Dec.ny.gov‚ 2014). When the algae bloom decompose‚ the decomposers that break down these algae use the already minimal oxygen in the water through respiration and because of the sheer

released statistics show that 2005 was one of the worst years ever for Florida’s manatee population. One of the leading causes of death was “Red Tide”. Scientists have now linked the effects on the manatees to the human population. Red Tide‚ or blooms of the algae Karenia brevis‚ release toxins which cause respiratory effects as well as immune depression. The red tide events seem to be increasing‚ especially on Florida’s west coast. One controversial theory for this increase says that nutrient

Symptoms include nausea and neurological symptoms like slurred speech. 2. If harmful algae blooms were to occur in major fishing areas it could lead to major economic issues. The fishing market would be devastated‚ as the marine organisms of the area have been contaminated. Many people would be out of work. There would be a substantial amount

5.4 Eutrophication 5.4.1 Outline the processes of eutrophication. Eutrophication is the addition of excess nutrients to a water system‚ which leads to the growth and subsequent death of algae‚ which reduces the dissolved oxygen available for other aquatic organisms. The main stages or steps of eutrophication are (in order): Nutrients wash into a river or stream. Algae grow quickly in response to the added nutrients. The algae block sunlight to aquatic plants‚ so photosynthesis slows‚ and
