Phosphates are not very water-soluble, thereby creating a limiting potential for plant-growth in marine ecosystems. This explains its encompassing effect on the surface of affected water system, as observed in the Watershed Nature Centre. In addition, this can be observed from the site as less quantity of phosphorus get dissolved in running water compared to the amount that eventually gets into the water column. Temperature: The water surface gets heated up by sunlight, increasing the water temperature. It is noticed that increase in temperature precipitate phosphorus effect, creating a high level of alga in water system. This is much practical by comparing the water system in the summer and other season. The former being much covered with algae, and the latter lesser. Temperature can also determine the percentage, or saturation level, …show more content…
Ecological impacts of the pollution on local environment.
Eutrophication: Eutrophication is rapid growth of phytoplankton and other aquatic organism in aquatic environment in response to excess addition of nutrients such as nitrogen and phosphorus. Eutrophication can be caused by natural or cultural processes. Natural eutrophication occurs naturally when a lake or stream ages over a century or thousands of years, while cultural eutrophication is anthropogenic in nature. Eutrophication cause in the Watershed Nature Centre Lake can be classified as cultural with the accumulation of algal population, resulting to pollution and thereby imbalance in the aquatic ecosystem Dissolved oxygen depletion: The rapid growth of the algal population in the lakes can cause the death and decay of phytoplankton and other aquatic life. This leads to the decrease in dissolved oxygen in the water levels. The quality of water can be further reduced when bacteria decomposes dead algae and use up additional dissolved oxygen. Oxygen depletion (hypoxia) is the direct effects on aquatic environment including fish
