Dissolved Oxygen Lab Report

505 Words3 Pages

Dissolved Oxygen (DO) is one of the most crucial properties of water quality; the oxygen dissolved in a body of water is used by all of the life within. Fish, plankton, bacteria, and other organisms in a body of water need oxygen for their cellular (and macro) respiratory systems. Without sufficient levels of oxygen in the water, life could not live within (src). 4-5 mg/L is the minimum DO concentration that can accommodate a variety of fish populations, and a large shift of DO can have drastic effects on the ecosystem. Different fish and underwater organisms require different amounts of DO to survive, but usually they need more than a bare minimum for reproduction, for their eggs, and for younger stages of life. A DO concentration of above 9 mg/L will support the widest variety of fish (src). Dissolved Oxygen levels do not affect humans or animals directly, although changes to the ecosystem around the body of water as a result of high or low DO levels can affect them. …show more content…

Using these results, the Swimming Area has the highest Dissolved Oxygen levels and is thus best suited for organism life in terms of oxygen levels; however, all four locations are above the previously listed 9 mg/L concentration, the level that supports the widest variety of fish and other life in the pond. The variances in DO levels among the locations are large but do not greatly affect the life in the water, since past the 9 mg/L the differences in the variety of life are minute, yet a greater concentration past this point may allow for an even higher density of fish and other organisms in the

Yellowwood Lake Lab Report

If the wind is blowing either East or West the plankton are more likely to be distributed because the lake runs North to South. The air temperature on September 17th, 2015 was 27 degrees Celsius with a cloudless sky and winds blowing from the West at 10 mph. To test the temperature profile of the water column we used the water sampler to collect water starting from the surface and taking it a half-meter down each time. After performing this at multiple depths you record the temperature after 2 minutes from each sample and any relative information about that water. We counted for a hundred protists at each depth (2, 3, and 4 m), 5 rotifer cells at each depth (2, 3, and 4 m), and 5 arthropod cells at each depth (2, 3, and 4 m).

Nitrates should be greater than or equal to one parts per million (ppm), phosphates should be less than or equal to .1 ppm, and the pH values should be about equal to seven. The dissolved oxygen in the river depends on the temperature, if the temperature is cooler than the dissolved oxygen levels will be higher, but the recommended amount of dissolved oxygen should be greater than or equal to five. For a healthy river the turbidity levels should be 120 centimeters

Lake Wheeler Lab Report Results

Abstract The purpose of this lab was to determine the overall health of the aquatic community at Lake Wheeler. Various water and sediments samples were taken to be tested and observed in a number ways to reach a conclusion about this lake’s condition and fitness. The dissolved oxygen content, pH level, water temperature, and water clarity were also tested with the use of several different tools, ranging from a Secchi disk to pH strips and more complex contraptions like the Schindler-Patalas trap.

For example, algal blooms can lead to a reduction in the amount of light that can make it through the water (Rice University, 2013). This causes plants to die off, which then results in oxygen depletion. Oxygen depletion means that there is little to no oxygen in the water. An environment becomes anoxic when it has zero amounts of oxygen (Darley et al., 2013). This results

Plankton Activity Postlab, Questions And Answers

Plankton Activity Postlab 1) Apply 2.5: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. Explain how the abundance of phytoplankton in the pond depends on the abundance of an abiotic resource such as nitrogen. - Phytoplankton are the producers in the pond. Species of organisms in ecosystems have their own carrying capacity relative to other species, and carrying capacities are determined by particular abiotic and biotic resources in an ecosystem. An increase in nitrogen levels in the pond (e.g. from fertilizers) will result in a dramatic increase in phytoplankton levels, but once phytoplankton population reaches its carrying capacity (determined by availability of other resources besides nitrogen, [DO] levels, predation etc.),

Inorganic Acid Lab Report

Arsenate can replace inorganic phosphate in step 6 of glycolysis that produces 1,3-bisphosphoglycerate instead of glyceraldehyde 3-phospahte. This yields 1-arseno-3-phosphoglycerate instead, which is unstable and quickly hydrolyzes, forming the next intermediate in the pathway, 3-phosphoglycerate. This is the same product that is normally formed in step 7. This is a problem because the product forms before it should and therefore does not reach the enzyme so the energy released cannot be harvested to generated ATP. Arsenate wastes energy by the uncoupling phosphotransfer reaction so its very POISONOUS.

Oxalate Lab Report

1.0 Introduction Oxalates which refer to any salt or ester of oxalic acid are common constituents of plants and are found in the majority of plant families. They occur either as free acids, soluble salts of potassium, sodium and magnesium and the insoluble salt of calcium. The amount of oxalates in plants ranges from a few percent of dry weight to up to 80% of the total weight of plants. (Garcia-Fernandez et al., 2014) The amount of oxalates in plants ranges from a few percent of dry weight to up to 80% of the total weight of the plant.

Marine pollution such as presence of organic matter in the ocean can result in the condition known as hypoxia or oxygen depletion and this can have adverse effect on the marine life including plant and animals and fish. Death of these fish can result in loss of millions of US dollars that are generate from the fishing industry. Marine pollution can also result in presence of foul smell resulting from the decomposing sewage being directed to the ocean and this has the effects to hinder recreational activities taking place in the sea as well as cause discomfort and breathing problem to the surrounding population (Laura, 11).marine pollution can also result in danger to human health. The human swimmers and water sport lovers can become endangered by swimming in the polluted marine waters (Laura,
