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
According to the article “How Tap Water Became Toxic in Flint, Michigan,” written by Sara Ganim and Linh Tran, the residents of Flint, Michigan highly disapproved of the new water source. Around 2 years ago, the city of Flint was forced to switch their water supply from Lake Huron to a more local source, Flint River. Before, this was not a big problem to the residents of Flint because they were told that the water they were drinking was harmless. However, people began to doubt that the water they were drinking was safe because it looked like sewage. Over time, new evidence began to arise claiming that the water contained massive amounts of lead and iron.
Most damages when exposed to teratogens occur during the embryonic period. Lead exposure during the embryonic period can cause stillbirths, increased risk for malformations, and VACTERL syndrome; VACTERL association is a disorder that affects

The purpose of this report is determine if sodium chloride is a viable option as a deicer on winter roads. To determine this, one must compare a multitude of factors. In this lab, the freezing point depression of water, enthalpy of dissolution, cost, and environmental impact will be discussed. A large factor in how effective a substance is as a deicer is it’s ability to decrease the freezing point of water. If the freezing point of water can be lowered, the outside temperature must be much colder to reach this new freezing point, resulting in less ice on the roads.
However, there are many unknown compounds present in water, which could pose health risks if not removed. Identification of unknown compounds is based on comparison of the mass spectra of the peaks in the sample with mass libraries or interpretation of the fragmentation. The identification of water contaminations is interesting and similar to the Unknown White Compound lab by making comparisons to other compounds to help identify the
One of the most difficult challenges that faces our society about water pollution is cleaning after a body of water have been contaminated. Our design team aimed to design a sufficient water filter that would improve the water quality in a body of water have been contaminated. An ideal body of water should be contaminant free, with a high potential Hydrogen (pH) and Nitrogen Dioxide (DO) level. Low pH and DO level which could cause health hazards to individuals who used the water as a drinking water. 2.
The city of Flint, Michigan and its residents have been suffering from their own tap water for months. When a resident turns on a water faucet in their home, the water emits a strange smell and the color comes out brown. It turns out that water contains a high amount of iron and lead. What made the tap water contaminated? Why is the city unable to obtain clean tap water despite being under one hundred miles away from the Great Lakes?
Drinking contaminated water can cause different types of cancers and also infertility and birth defects due to of the presence hazardous chemicals. Impoundments that have not been built or properly closed off have led to the death of many animals and also health issues in
Recent studies have shown that the water in Flint, Michigan has been contaminated by a horrible health impact, lead. This has happened because nearly two years ago, the state of Michigan decided to save money by switching Flint’s water supply from Lake Huron, to the Flint River a notorious tributary that runs through town known to locals for its filth. This has led to many terrible effects shown in both children and adults. The many effects lead has on children and adults are very drastic if not taken care of properly they could have lifetime effects. Dangerous effects lead can lead to that effect children.
Residents started to report that they were experiencing rapid hair loss, chronic migraines and blurry vision. (congressional digest) - These are common side effects of lead poisoning that can be fatal if not treated in time. b. A funding plan is under go as we speak to tackle the current crisis at hand. - Republican proposal of $50 million and $500 in
The refining process, only possible through mercury amalgamation, was harmful to anyone who came
Chapter five titled “Mercury” of The Poisoner’s Handbook by Deborah Blum gives a fascinating story, about a woman named Gertie Gorman who was married to a man named Charles Webb. Many believed that her husband poisoned her because in her will “[she would leave] everything to her husband” (112) giving him a good motive for that action, but as the investigators opened up the body they found the presence of mercury bichloride, which was a “messy killer” (114) meaning it was hard to miss because of all the bloody inflammations. As the investigators looked more into the case they found out that Webb was not the person responsible for his wife’s death, however Webb was still prosecuted. Mercury can be poisonous if taken in extreme quantities causing the same things it did to Gertie’s body.
A hydrate is a compound, where water molecules are chemically bounded to another compound or element. An anhydrate is the substance remaining after removing water from a hydrate. The hydrate in this lab was Copper Sulfate. The hydrates formula is CuSO4 times xH2O. The purpose of this lab was to pull the water from a hydrate to expose the anhydrate and calculate what the hydrate is by finding the formula for the
While the magnesium metal is the most reactive, magnesium nitrate is the least reactive. Copper metal is the least reactive but copper nitrate is most
