What Is Eutrophication
Posted on: Tuesday, December 31st, 2013 at 3:04 am
Eutrophication or algal bloom is considered to be the most dangerous and unhealthy condition of a pond that is caused by certain human activities. Humans use a lot of fertilizers in the agricultural fields because of which the runoff from the fields contains excess of nitrates and phosphates. When this runoff reaches different ponds, it pollutes the waters of the ponds to such an extent that algae start growing continuously in large quantities because of which the ponds look absolutely ugly. This unsightly condition of the pond is known as Eutrophication.
The word “Eutrophication” has its origin from a Greek word and that word means “overfed”. When Eutrophication occurs the pond ecosystem turns into a dead ecosystem. When algae start growing in the ponds, the oxygen supply to the aquatic plants and animals is reduced because of which they start dying. Slowly and slowly the aquatic plants and animals are replaced by more and more algae. Algae also produce harmful toxins that can cause severe damage to higher animal forms. This in turn will disrupt the food chain.
Along with agricultural runoff, there are other causes of Eutrophication such as animal excrement, street runoff, organic debris and so on. Eutrophication has recently become the cause of concern for a lot of countries. Many major countries are having conferences in relation to Eutrophication so that this unhealthy condition of ponds and even other water bodies can be avoided by utilizing effective methods.
Once Eutrophication occurs it is very difficult to restore the pond to its previous pristine condition. Aerobic bacteria can be utilized to restore the oxygen supply to the pond. In addition to that, aeration system can also be highly effective in ensuring that the oxygen supply can be restored to the pond efficiently. However, these two methods are not that competent and helpful.
