Eutrophication occurs when ...

Eutrophication occurs when the environment becomes polluted by plant nutrients such as phosphates, nitrates, etc and this leads to increased weed growth and algal (blooms)in water. This algae of bloom disrupts normal ecosystem functioning and causes many problems including use up all the oxygen in the water and this can result in the death of many aquatic organisms such as fish. The bloom or algae may also block sunlight from photosynthetic marine plants under the water surface. Some algae produce toxins that are harmful to higher forms of life and this can cause problems along the food chain and affect any animal that feeds on them. To prevent eutrophication Prevent water pollution of nearby rivers and lakes as well as groundwater and drinking water by following these: -Take great care not over use pesticides and fertilisers to prevent runoffs of the material into water sources. -Don't throw wastes into rivers, lakes or oceans; help to keep the beaches safe from any waste by cleaning or setting the dustbin everywhere if necessary. -Use environmentally households products such as washing powder or households cleaning agents. -Don't throw oils down the sink or toilets. -Conserve water by turning off the tap when necessary to prevent water shortage and reduces the amount of contaminated water that needs treatment. Remedies: To improve water quality, many water treatment methods are available and each methods has its own special application field or is suitable to improve one or more quality parameters. -Aeration by contacting water with air for uptake or release of volatile compounds in water. Release of volatile substances Oxygen in case of super saturation(raw water with algae). -Application of A carbon powder (PAC) in water treatent to remove the taste and odour that produce compounds from algae.
