Harmful Effects of Algal Bloom on Aquatic System: Algal blooms leads to so many harmful effects on aquatic ecosystem, some of these harmful effects are given below: Risk on Human Health and Life: As algal bloom produces toxin in water bodies which is indirectly consumed by human beings which further leads to fatal disorders or disease like itching, several skin related diseases, etc. Algal blooms are known to be mainly composed of bio-toxins and are characterized by a distinct discoloration of water due to a large number of pigmented algae cells. The overgrowth of algae consumes oxygen and blocks sunlight from underwater plants. Harmful algal blooms can occur in lakes, reservoirs, rivers, ponds, bays and coastal waters, and the toxins they produce can be harmful to human health and aquatic life. It is important to highlight the fact that some instances of algal bloom are harmless. When turbidity is low, more light can penetrate through the water column, and optimal conditions for algal growth created. Only run your clothes or dishwasher when you have a full load. Because harmful algal blooms affect people, animals, and the environment, it’s important to track when they happen, where they happen, and whether they cause illness. Exposure to marine HAB toxins can occur through direct contact by swimming, breathing in aerosolized toxins (toxins in water turned into tiny airborne droplets or mist), or eating toxin-contaminated shellfish or finfish 1. Effects of Algal Bloom There are hundreds and thousands of species of algae. Algal blooms need large masses of water, which are almost still to thrive. Algal bloom and water hyacinth are some of the most common forms of eutrophication, which depletes the supply of oxygen, leading to the death of animal life. Use of Non-toxic Cleaning supplies at Home, Trump Tells ‘60 Minutes’ Climate Change Will Reverse Itself and He Doesn’t Want to Put Anything at Stake in Fighting It, Deforestation in the Congo Basin, an Attack on the World’s Atmospheric Purity, 2. The presence of algal bloom makes transport on waterways cumbersome, leading to more expensive means of transport such as air. Low turbidity occurs when there is only a small amount of suspended matter present in the water column. All these increases the costs of treatment and the demand for water, which eventually dramatically raises the water utility bills for domestic consumers. As well as recording the location and date of the bloom, we need you to submit a photo of the bloom to help us verify your record. Figure 1. Dead zones are areas of water bodies where aquatic life cannot survive because of low oxygen levels. The state Department of Environmental Conservation’s Harmful Algal Bloom Program has also confirmed AWI’s findings and added it to the state database. With the dense growth of algal blooms on natural recreational water surfaces, the tourism industry suffers greatly as the resulting foul smell, and dead zones mean there are no fishes to watch, no available ways to navigate the water, and no swimming or boating activities. In addition, children weigh less, so a smaller quantity of toxin may trigger an adverse effect. Clean water raises the value of a nearby home by up to 25 percent, whereas waterfront property values can decline because of the unpleasant sight and odor of algal blooms. Also known as hypoxia, these areas are caused by algal blooms consuming oxygen as they die and decompose. This means that the presence of algal blooms will cause additional water treatment costs to get clean water leading to increased overhead costs. Although not all algal blooms in the ocean produce highly visible effects nor are all blooms harmful, they nonetheless affect life in the ocean and on land in both beneficial and harmful ways. These waves are sent over the top layer of the water bodies to counter the buoyancy, making them sink and disable photosynthesis. The report is an update to the 2017 report, and serves to inform policy makers, practitioners, resource managers, and stakeholders about scientific advances in understanding and monitoring these phenomena and the effectiveness of conservation approaches, … Harmful algal blooms cloud surface waters, blocking sunlight and preventing the coral’s algae counterpart from growing food for itself and the coral. Judge orders engineers study Lake O water release effects on algal blooms, endangered species Published: October 29, 2020 5:54 PM EDT Updated: October 29, 2020 6:17 PM EDT This technology focuses on ultrasonic sound waves in water bodies to look for algal blooms and to control their growth if discovered – reducing algae growth by up to 90%. In effect, the fish suffocate. As a result, the area around the algal blooms will be a dead zone with a dead animal and plant life alike. Use a commercial car wash that requires disposing of wastewater properly, and many of them filter and recycle their water. Consumer Surplus Ballast Water Harmful Algal Bloom Surplus Loss Halo Effect ... (2002) The economic effects of harmful algal blooms in the United States: estimates, assessment issues, and information needs. Harmful Effects of Algal Bloom on Aquatic System: Algal blooms leads to so many harmful effects on aquatic ecosystem, some of these harmful effects are given below: Risk on Human Health and Life: As algal bloom produces toxin in water bodies which is indirectly consumed by human beings which further leads to fatal disorders or disease like itching, several skin related diseases, etc. These toxins harmfully affect their developmental immunological, neurological, or reproductive capacities. This article seeks to provide a better understanding of the causes, effects, and possible solutions for an algal bloom. Effects of Algal Bloom on Aquatic Ecosystems 1. Therefore, like other bacteria, the algae bacterium is facilitated by the presence of dead organisms in the water. Their large presence on the water and their well propagating sequences leads to quick contamination of water, thus posing a health hazard to humans.
