ES Lab Report †Nitrate

Background IntroductionThe presence of normality is vital for all organisms as it is an element of protein. It is present in the environment in mixed compositions and eer changes from one to another as it goes through the Nitrogen cycle. Nitrate and nitrite argon both compounds of nitrogen, which are found in natural sources such as soil, piss, plants and food. These compounds are formed when microorganisms in the environment break down total materials, such as plants, animal manure, and sewage. This is useful as most of nitrogen absorbed by plants is in the form of treat. However, since process is extremely leachable, it really quickly moves with irrigate through the soil and in the event of extravagantly amounts of rainfall or excessive irrigation, this can permeate through the various soil layers and reach the ground wet supply sources. Nitrate can get into alcoholism peeing from runoff or seepage into ground weewee from farms, golf courses, category lawns, etc. In a well, nitrate may get into the water more easily if the well is poorly constructed.The presence of nitrate in water is extremely difficult to detect, as it does not have whatever color, odor and is tasteless. The most significant health hazard of the presence of nitrate in drinking water is when the nitrate present in the water is transformed to nitrite in the digestive system. This causes a condition called methemoglobinemia, which occurs due to the oxidation of hemoglobin to form methemoglobin. Methemoglobin does not have the corresponding oxygen carrying top executive of hemoglobin.Effects of nitrate in drinking water are as follows exuberant levels of nitrate in drinking water have caused serious sickness and sometimes death. When there is too much nitrate in fresh water or estuarine systems close to land, nitrate can reach proud levels that can potentially cause the death of fish. Escalated potential risks of cancer from nitrate and nitrite in water and food are also rep orted.In this experiment, we are tone ending to measure the level of nitrate or nitrite present in our water system by comparing tap water with grey water. colorize water is non-industrial wastewater generated from domestic processes such as washing dishes, race and bathing.Aim of ExperimentBy investigating the elements of nitrite or nitrate that our ground water has, we as a class can determine which residential surface areas have the most health-threatening water. The father of this experiment is to raise awareness in high school students on health-threatening issues such as the potential risks of nitrate in water.HypothesisUnlike countries like Australia or Singapore, Indonesia is not commonly associated with clean tap water. In fact drinking tap water is not recommended nor practiced. Inspite of this common notion, there are in truth few health issues related to clean water in Jakarta. The shot put forward by this experiment is that the nitrate level in groundwater in area s around Jakarta would be minimal.Materials and EquipmentsGrey water, Tap water, Nitrate-nitrite meter, Function graph, Calculator, interrogation chemical.Independent Variable LocationDependent Variable Amount of nitrate/nitriteMethods Collect plentiful venerable water and tap water from houses in different areas. jell the same volume of water from each source into different test tubes. Put the testing chemical inside each test tube to arrest nitrate/nitrite level. Measure each nitrate/nitrite level using meter. correspond result using a mathematical function graph. Use calculating machine to calculate final results. Interpret data.DiscussionAs seen from the results the level of nitrate found was minimal. The area around Lippo Karawaci and Sudirman has the biggest chance of having nitrate in their water. This being said does not mean there is 0% possibility that nitrate is present in other areas. This experiment is probably not as detailed as it should be therefore ach ieving zero results in most of the areas.EvaluationEven though the results face extremely minimal amounts of nitrate present in the water sources In Jakarta, one cannot draw permanent conclusions that it safe to drink. Alternate sources of drinking water such as bottled water or spring water are always recommended, especially in the case of infants and pregnant women. Boiling of water is not a solution, as this only tends to increase the concentration of nitrate in water.The hypothesis states that the nitrate level around Jakarta and its meet suburban areas will be minimal. The experiment confirms the hypothesis. However, since the sample size was particular the reliability of the results is debatable.
