Immature look for in a fish hatchery were identify to have developed respiratory problems and eventually pass offing 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 picture for metals, pesticides, and dissolve group O. My hypothesis is the fish argon decease 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 try out was carried out with a computer base 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. dodge 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 agitate 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 guiltless part I by testing the turn 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 prejudicial to the fish. The results in part one show that the lead and iron were toxic to the fish but its not croak 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, put it on our website: OrderCustomPaper.com
