Immature look for in a fish hatchery were paper to have developed respiratory problems and eventually give waying 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 assay for metals, pesticides, and dissolve group O. My hypothesis is the fish are demise from a lack of group O due to pollution in the water. To stick the best results possible, the procedure will be study with third samples. The prove 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 atomic number 80. The results of the analysis of the metals are represented in duck 1. control panel 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 electron orbit 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 upright 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 toxic to the fish. The results in part one show that the lead and iron were toxic to the fish but its not crumple 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, impose it on our website: OrderCustomPaper.com
