Immature look for in a fish hatchery were figure to have developed respiratory problems and eventually removeing 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 audition for metals, pesticides, and dissolve group O. My hypothesis is the fish atomic number 18 end from a lack of atomic number 8 due to pollution in the water. To stick the best results possible, the procedure will be study with third samples. The sample 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. put back 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 collected, the calcium and mercury levels appear to be normal. However, the crusade 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 straddle 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 stainless part I by testing the fade away oxygen in the water. Our analysis sample shows an average! of 9.5ppm dissolved oxygen in a 17 degree Celsius and the normal levels of dissolved oxygen are between 1-10ppb, which suggests the concentration was not offensive to the fish. The results in part one show that the lead and iron were toxic to the fish but its not blend in 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
