Thinking About the Problem
For my science experiment project I am testing to see which chemical is the sanitizer for a hot tub or pool. This "Thinking About the Problem" will help me think about my topic and gather information to modify the variables in my experiment. The following chemicals are sanitizers that are used to control bacteria and algae growth. They also reduce the risk of viruses and microorganisms as well as help keep the water clear. The two main methods of sanitization are Chlorine and Bromine. Chlorine is the most widely used pool/hot tub sanitizer, it comes in liquid, granular or tablet form. Tablets are best for keeping a steady supply of chlorine over a long period of time, while liquid

It is available in tablet and granular form and considered to be softer on swimmers than chlorine as well as having less of an odor than chlorine. It is very sensitive to UV light so it dissipates quickly if the pool is exposed to a lot of sun. When using bromine you may find that you are constantly adding more of this chemical. A pressurized feeder called a brominator can be used to slowly supply the pool with bromine. Although bromine is expensive in comparison to other chemicals, bromine is more effective at killing algae than chlorine and is just as effective at killing …show more content…
Hydrogen peroxide is often used in homes as a disinfectant for small wounds or for other cleaning purposes. It can be bought in concentration as high as 35% which is great for long term use. To use hydrogen peroxide you only need one ounce of 35% hydrogen peroxide per 100 gallons of water for every day you use the hot tub. Biguanides or PHMB which is short for Polyhexamethylene Biguanides are completely Chlorine and Bromine free. Biguanides are not usually recommended because they are more expensive and cannot be combined with some pool chemicals, such as chlorine and bromine. Though they are considered to be one of the most swimmer friendly chemical sanitizers available and effectively kill bacteria and algae in pool water. Biguanides also stay in the pool water longer than most other sanitizers, making it easier to maintain other than weekly use of a hydrogen peroxide based oxidizer. Ionization is a natural alternative to common pool chemicals. It uses copper and silver to kill bacteria, viruses, and prevent algae and chlorine is only needed for weekly shock treatments. On the downside, high levels of copper can lead to green hair and staining on pool surfaces. When using a sanitizer, frequent water testing is needed to ensure complete water sanitization. When testing ionization you are monitoring the copper
Environmental Science and Sustainability (SCI201 -1504A -07) Instructor: Trena Woolridge Unit 4- Discussion Board Amanda Kranning October 27, 2015 Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.(Cloern, Krantz, & Hogan, 2013) Eutrophication forms when an abundance of nitrogen and phosphorus increases growth within an environment.
Check for household sprays containing the ingredients of pyrethrins and pyrethroids. These ingredients will be listed on the label as bifenthrin, cyfluthrin, tetramethrin and phenothrin and kill the silverfish on contact. Some of these products have residual action and continue to kill for days or sometimes weeks after the
You can get a standard tub that just allows you to soak in very hot water to soothe your sore muscles, or you can buy a hot tub for entertainment and exercise. You can use it with cool, cold, or warm water. A hot tub is very versatile, so you can customize it to the way you like to spend your time in the
Enjoying a hot bath is a great way to relax after a long and stressful day. The best thing to do when you want to take a bath is to add a bath bomb. There are many types that you can use, but making your own is the best way to go. A great option is hot cocoa bath bombs. Adding hot cocoa bath bombs to a hot bath will be perfect for any cold winter day.
In the event that you keep the hot tub clean, it will definitely last longer. Nevertheless , there are ways one can possibly avoid the cleaning too often, with oil absorbers. This spa accessory is simple to operate rather than expensive. Nevertheless it is useful and valuable because it helps you to associated with general maintenance simpler. Petrol absorbers mainly remove certain residues from the drinking water, like lotions or body oil.
Alexis: Good Morning and welcome to AASN Morning Show! I’m joined here today with Dr. Angie Cibic to talk about the danger of plastic water bottles and BPA. Angie: Yes, at IHJB Science Facility we have been researching the effects of plastic water bottles for over 13 years.
These facts introduce and support the message that Standage is delivering. Standage continues with many statistics: “Admittedly, both kinds of water suffer from occasional contamination problems but tap water is more stringently monitored and tightly regulated than bottled water. New york city tap water, for example, was tested 430,600 times during 2004 alone.” He stated. Even though he admits that both of each kind contains chemicals-which at the same time Standage claims that the tap water is more sanitized-but also he points out that it is not the taste that differs between the two
The particular classifications of contamination and sullying are microbiological, eutrophication, compound, suspended solids, strong squanders, warm, radionuclides, and spills. Microbiological squander for the most part comprise of the waste , material discovered I therapeutic waste. Despite the fact that there are particular directions for discarding this waste material, the contamination comes to fruition when those guideline are not being permitted. ("Water: Laws and Executive Orders," 2010). Eutrophication is an extreme wealth of supplements in a lake or different waterways.
Often people use hydrogen peroxide to clean wounds instead of alcohol. The reason for this is that, it does not have a burning sensation after applying it, while alcohol on the other hand has a burning sensation. After the supplication of this chemical, the skin absorbs this chemical, it disrupts the homeostasis of the body. Hydrogen peroxide is often used for small cuts or an affected area. Once applied to the affected area, this chemical releases oxygen, which creates foaming that helps both the removal of dead skin as well as helps clean the affected area.
Chlorine is manufactured commercially by running an electric current through salt water. As results of this process a free chlorine, hydrogen, and sodium hydroxide are produced. Consequently, the Chlorine is changed to its liquid form by compressing the gas, the resulting liquid is the chlorine, which is usually mixed into drinking water and swimming pools to disinfect bacteria. Unfortunately, the chlorination causes the formation of the Disinfection By-products (DBPs), also known as Trihalomethanes (THMs) as a 90% of the population is drinking water that contain (DBPs). Researches proven that THMs is causing cancer in the laboratory animals.
Effect of Yeast on Temperature on Hydrogen Peroxide Solution in Water Khalid Al Sabeeh Ms. Dobrin 11-G Chemistry HL Jan 5, 2015 Abstract: Within this lab yeast was added to hydrogen peroxide solution in water. Temperature was the factor to be tested. In all trials, the initial and final, when yeast was added temperatures increased by 10˚C respectfully per trial.

How can hand sanitizer be a cause of… sickness? It may seem ridiculous, but there is a way to connect the two. Hand sanitizer is a cause of kids being rushed to the hospital. This anti-germ fluid may seem harmless at first glance, but going in depth unravels a whole new story.
This is also known as hot tub rash, and it is actually some sort of infection caused by the germ called Pseudomonas aeruginosa. Once you are contaminated with this bacteria, you will deal with itchy, bumpy red rash and pus-filled blisters. The rash will go away on its own, and you won 't need to see a doctor, but until this happens you will feel quite uncomfortable. How can you avoid this? The answer is simple, you need to avoid soaking for long period in a hot tub that it is not
increase in Ca levels and hypersensitivity reaction.2,3 There are many classes of Diuretics such as loop diuretics, potassium sparing, thiazide, osmotic diuretics. They are classified according to mechanism of action, site of action, chemical class and effect on urine electrolytes. Each class vary widely in its efficacy.1,2 At the 16th century, calomel (mercurrous chloride) was used as diuretic, but its poor absorption from the GIT limited its use and was replaced by the organomerrcurials(chlormerodin) which was highly effective, but unfortunately its parenteral use and possibility of toxicity and tolerance limited their use and they are no longer used, so scientists searched for more safe and effective
