Water Quality Water Quality Criteria are levels of individual pollutants or water quality characteristics‚ or descriptions of conditions of a body of water that‚ if met‚ will generally protect the designated use of the water. For a given DU‚ there are likely to be a number of criteria dealing with different types of conditions‚ as well as levels of specific chemicals... Water quality criteria must be fit the use of water. Only scientific considerations are taken into consideration when determining

Causes of Water Pollution * With environmentalism and green thinking reaching the pinnacle of public appeal in recent years due to global warming‚ an increasing focus has been put on stopping pollution‚ especially carbon dioxide emissions. As such‚ the main battle has been waged against air pollution‚ while water pollution has not been in the public limelight. This does not mean that the problem is any less important‚ or any less pervasive however. Water pollution is caused by the release of

The Effects of Harmful Algal Blooms and Eutrophication Introduction Eutrophication‚ by definition‚ is a process where bodies of water receive excess nutrients that stimulate excessive plant growth. Eutrophication results from continuous pollution in the form of agricultural run-offs or sewage outflows. Fertilizers and sewage are both rich in nitrogen and phosphorus‚ which are both nutrients essential for plant growth. However‚ these nutrients are typically low in content in aquatic environments

DECISIONS SERIES Oxygen Saturation A Guide to Laboratory Assessment BY SHANNON HAYMOND‚ PHD uman life depends on the oxygen transport by hemoglobin. In healthy patients‚ the majority of molecular oxygen (O2) is bound to hemoglobin and only a small fraction is dissolved in blood. But in patients with respiratory problems or certain metabolic and genetic disorders‚ the fraction of oxygenated hemoglobin can fall to dangerously low values. Therefore‚ laboratory assessment of oxygen saturation (SO2)—the

Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater should
