Water Contamination Lab Report

The first line of defense against germs is simply washing our hands. We wash our hands for many different reasons, but the main reason is to wash off all the bacteria and viruses that have ended up on our hands through the things we’ve touched. We can pick up germs from anywhere, you can pick them up from touching animals, using the restroom, touching your nose, and from even just using a keyboard that someone else has used before. Those are just some ways that you can pick up germs though our daily lives. Defensive handwashing is key to fighting germs and bacteria.

A maintained negative pressure during withdrawal may lead to 1. The aspirated syringe should be rinsed with fluid to recover the specimen. 2. Contamination of the overlying tissues during withdrawal. [7] Fine needle sampling without aspiration

For example, to get a little bright red blood on the paper when you wipe yourself after using the toilet, or blood splashes in the toilet. Blood is often clear and not mixed with feces. Other symptoms may be that it itches and stings around the anus gases and a little stool or mucus leaks out without being able to stop it because it hurts when you empty the gut that you know something that bulges at the anus. The pain may be due to the intestinal mucosa has been irritated adjacent to the hemorrhoid and the formed small cracks.

If the urine lab results show that the urine is too concentrated, this could be an indication that the patients kidneys are not functioning properly. If your lab results showed your urine had a pH of 6, then that is a great sign because that is the average pH in healthy individuals. Although your pH was in what is considered a normal range, the turbid appearance and amber color suggests that you need to increase the amount of water that you are drinking daily. Your lab results showed that there was no protein in your urine. It is important that a patient would have no protein in the urine because then they would have something called proteinuria.

Larson & Bobo (1992) state that while ethanol and isopropanol may reduce viable bacterial counts on hands, this does not obviate the need for hand washing with water and soap whenever hands are dirty or visibly contaminated with proteinaceous materials, e.g blood (Larson, 1988). Several studies recommend, the use of gloves and routine hand washing with soap and water after care of CDI patients rather than alcohol based hand rub for mechanical removal of spores from hands (Siegel et al, 2007) (Haut, 2008) (Vonberg et al. 2008).

Tissue Papers Absorb Less Liquid in Volume When Concentration of Salt Increases This study was done in an effort to find out the minimum number of papers needed to wipe up a spill so that anyone could prevent wasting paper. In this investigation, sheets of tissue papers were dipped into salt water with different concentrations and soaked until the water traveled to the top, then the amount of water a paper absorbed in terms of both the mass and the volume was recorded. The result showed a strong, positive linear relationship between mass absorbed and salt concentrations, while it showed a slight decrease in volume absorbed with increasing salt concentrations. Further researches could be done to change the substances or even mix different solvents

Our topic is clean water and sanitation. The product is a tablet that turns any type of substance into clean substance. The water can be sea water, sewage water or any other dirty water. The tablet dissolves into the liquid and releases some of the chemicals to purify the water instantly. The filthiness in the substance will then sink to the bottom, where the other chemicals in the tablet will absorb all the dirt.

Initially not all of the 5.0grams of benzoic acid went into the round-bottomed flask as there was still residue left on weighing boat. This would mean the starting amount of benzoic acid was less then stated. There was some product loss during the draining of the aqueous layers. All these will account for the low yield that was produced.

Once iodine was dropped onto the circle, which was labeled “HCL+ saliva”, was divided into two colours, white and navy blue, this arose because the starch did not get broken down. The enzyme got denatured with the extension of hydrochloric acid of hydrochloric acid. The acid found in hydrochloric acid obtains a low level oh pH (2), causing it not to be broken down, rather to be denatured, confirms amylase can’t continue it’s activity without a particular high amount of acid, (that is found in stomach acid). My hypothesis is incorrect due to the fact that my prediction is

Sodium bicarbonate (its official name) is mildly abrasive; gently scrubbing away surface stains to return teeth to a whiter shade. It’s also very alkaline (the opposite of acidic) so I would think if you have a very acidic mouth or eat a lot of acidic food, it could help balance out the Ph, which would be useful as acid breaks down enamel-this is strictly speculation on my part. It will also reduce the acidity of the lemon juice, which acts as a natural bleach of sorts. I use a mixture of baking soda and water on some days, and use the lemon juice on others, as I don’t want to overdo

We also did not find a high level of phosphates and nitrates in the water. My group also did a dissolved oxygen test on the water. The velocity of the surface water of the creek is at a normal rate. The Conodoguinet Creek appears to be healthy right now.

Pat dry skin gently rather than rubbing it dry. One should use a mild soap and avoid overly perfumed products. For example, the oil well to dissolve dirt without drying out the skin. At the pharmacy is different washing creams and shower and bath oils for dry and sensitive skin. One should be careful with conditioner and other hair products that can cause itching of the scalp.

There isn’t a cure for it so you can help reduce the pain and shorten the duration. Cool, wet compresses can reduce the pain, if there are blister add diluted vinegar (1 quarter cup vinegar for 2 quarts of water). Soothing baths and lotions help discomfort and itching, the inflicted should try to keep their skin clear and if lesions are oozing they should be kept away from others due to risk of infection. The anti-viral drugs acyclovir, valacyclovir, and famciclovir can be used to treat shingles and they may shorten the duration the course of the illness as well as the severity too, pain killers can also be used to combat the pain from the rashes. So if you have shingles you should: keep the rash covered, avoid scratching and touching, try to keep it clean, and wash your hands often to avoid the spread of varicella zoster

Other signal words to look out for are “may cause skin irritation, “flammable”, “vapors harmful”. Melaleuca’s natural cleaning agents and skin products are all natural. The MelaPower detergent has a pH of 7.5, it is 6 times concentrated, and just ½ fl.

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.
