Copper in large doses is dangerous to infants and people with certain metabolic disorders. On the other hand, lack of copper intake causes anemia, growth inhibition, and blood circulation problems. Iron in water is not a health hazard by itself but it may increase the hazard of pathogenic organisms, since many of these organisms require iron to grow. Lead is a cumulative poison, meaning that it remains in the body following exposure. Children under age three are most susceptible to lead poisoning. Minor symptoms include abdominal pains, decreased appetite, constipation, fatigue, and decreased physical fitness. Long-term exposure may cause kidney damage, anemia, nerve and brain damage, and death. Magnesium is quickly expelled from the bodies of healthy humans. People with kidney disease, however, may suffer from hypertension, confusion, muscle weakness, and coma. Manganese in large doses causes headaches, apathy, irritability, insomnia, and weakness of the legs. Long-term heavy exposure may result in a nervous system disorder. Mercury poisoning results in weakness, loss of appetite, insomnia, indigestion, diarrhea, gum inflammation, loosening of the teeth, irritability, memory loss, muscle tremors, and brain damage following large …show more content…

Analysis: Yes, we think that we produced an environmentally safe fluid and potable drinking water as our collected distillate from the mixture is odourless and colourless. It is as clear as water when we compared it with water and it does not have any visible particles too. The moringa seeds also removed most bacteria from the mixture. Thus the liquid produce is environmentally safe. Success of Water Treatment Machine (Instruction: Base on the priorities determined with the decision matrix, evaluate the success of your machine on a scale of 1 – 10 whereby 1 is the lowest possible score and 10 is the highest possible score. Provide an explanation of not more than 50 words below.) We feltl that we actually achieved at least a 9 or 10 out of 10 for the success of the machine as we fulfilled almost all of the 5 criterias in the decision matrix and still being able to produce at least or around 90% clear liquid, which means that our water treatment methods was effective. Bibliography and Citation (Instruction: Using APA citation style, cite the sources used in the report and state the reference materials used during the
