Immature look for in a fish hatchery were direct to have developed respiratory problems and eventually courseing them to death. In this look into we will determine the causes of the fish kill by sampling the pee in the lake. The samples will be take for metals, pesticides, and dissolve group O. My hypothesis is the fish are expiry from a lack of oxygen due to pollution in the water. To stick the best results possible, the procedure will be analyze with third samples. The look into was carried out with a computer ground simulation. We took samples of water from the lake to test the aims of adjure, lead, atomic number 20, and hydrargyrum. The results of the analysis of the metals are represented in duck 1. get across 1. Sample results for metals in lake water. Sample123average Lead (ppm)0.70.70.70.7 Iron (ppm)1.41.91.31.5 Calcium (ppm)26.825.021.124.3 Mercury (ppb)4.54.14.54.4 ground on the information contained in the library and the result colle cted, the calcium and mercury levels appear to be normal. However, the campaign at 1.5ppm level and lead at 0.7ppm level are disadvantageous to the fish in the water. Following this, we also measured the levels of pesticides in the water, whose toxic levels eye socket between 1-10ppb and can be fatal to several(prenominal) fish species.

Table 2 shows the results and analysis of DDT, PCBs, and Dieldrin. Table 2. Results for pesticides in water. Sample123Average DDT (ppt)0.30.80.40.5 PCB (ppt)0.90.40.70.7 Dieldrin (ppt)0.30.60.10.4 We clean part I by testing the fade out oxygen in the water. Our analysi s sample shows an average of 9.5ppm dissolve! d oxygen in a 17 degree Celsius and the normal levels of dissolved oxygen are between 1-10ppb, which suggests the concentration was not deleterious to the fish. The results in part one show that the lead and iron were toxic to the fish but its not fret on which was the major factor that killed the fish. In part II, the experiment was performed for the purpose of...If you want to get a full essay, prescribe it on our website: OrderCustomPaper.com
