Ethanol can corrode plastic, rubber and metal parts in pre-2001 vehicles, according to Forbes. The burning of corn ethanol can also release harmful greenhouse gasses and carcinogens into the air.Continue Reading
As of 2014, most commercial fuel for cars is 15 percent ethanol. Vehicles which are not specifically branded as "flex fuel vehicles" are in danger of having their engines damaged by the use of gasoline with that amount of ethanol. Forbes reports that many car manufacturer warranties include clauses that state the warranty is void if the car runs on gasoline with 10 percent ethanol or more. Cars made after 2001, or the aforementioned "flex fuel vehicles," do not suffer the same negative consequences from the use of ethanol.
Ethanol also serves a danger to the environment. Ethanol releases greenhouse gasses and carcinogens into the air, including the chemical benzene. Another issue related indirectly to ethanol is the farming techniques which generate the corn for ethanol's manufacture. Wetlands and grasslands are plowed in order to farm more corn, and in the process carbon is released into the atmosphere. Additionally, the use of more fertilizer endangers the environment and harms wildlife habitats as the fertilizer is washed from the fields. Environmental Working Group contends that ethanol is a greater threat to the environment than Canadian tar sands.Learn more about Chemistry
The American Academy of Orthopaedic Surgeons explains that total knee replacement involves four basic steps: preparing the knee by removing damaged cartilage and a small amount of underlying bone; replacing the missing tissue with metal components to recreate the joint's surface; resurfacing the patella or kneecap with plastic in some cases; and insertion of a plastic spacer between the metal parts to allow a smooth gliding motion. Total knee replacement is recommended for patients whose pain or stiffness prevents or limits daily activities such as walking, climbing stairs, and getting in and out of chairs.Full Answer >
Ethanol is a grain alcohol and can be used in the same way as gasoline. Most gas stations in the United States use a combination of about 10 percent ethanol and 90 percent gasoline, according to the University of Illinois Extension.Full Answer >
Ethanol is dangerous because it is a highly flammable liquid that can be poisonous with skin contact or ingestion in its pure forms. Ethanol is also the ingredient in alcoholic beverages, and consumption of it can lead to liver disease, heart problems and alcoholism.Full Answer >
Ethanol is a substance that is created from the fermentation of food crops in factories, while methanol is a highly poisonous chemical produced synthetically. Both substances are variants of alcohol that can be used as energy sources, but have different methods of production and practical uses.Full Answer >
