The fuel is harmful like gasoline

E85 fuel can help reduce two carcinogenic wastes, benzene and butadiene, but increase the concentration of two other wastes, formaldehyde and acetaldehyde. The new findings suggest that the new fuel made from ethanol also poses many risks to human health like normal gasoline fuel.

Atmospheric scientist Mark Jacobson of Stanford University, USA, thinks that the number of deaths and hospitalizations due to respiratory-related diseases will increase, if cars in the US will be applied. This latest type of technology runs on a high ethanol fuel.

Jacobson used computer equipment equipped with 3-D technology to measure air quality in 2020. That's when ethanol will be widely used throughout the United States.

He divided his research into two parts for comparison. One is to study the types of cars, trucks, motorcycles that are circulating nationwide and run on gasoline fuel. Two are the E85 fuel engines. It is a mixture of 85% ethanol and 15% gasoline.

Jacobson said the E85 fuel engines could help reduce two carcinogenic wastes: benzene (C ₆ H ₆ ) and butadiene (C ₄ H ₆ ), but increase the concentration of the other two wastes. formaldehyde (CH2O) and acetaldehyde (CH ₃ FOR). As a result, the carcinogenicity of the E85 fuel is as high as the fuel.

Currently, gasoline fuel is the leading cause of child deaths in about 10,000 people across the United States every year due to environmental pollution problems, Jacobson said.

He said: 'In our study, E85 is the main cause of increasing the number of people who die from atmospheric pollution-related diseases in the United States up to about 200 people per year, and compared to fuel. Gasoline, this number is 120 personal victims in Los Angeles ".

Jacobson published details of his findings on the April 18 issue of the online science and technology journal Environmental Science & Technology.

According to him, these figures may change if new methods to effectively treat emissions from ethanol fuel will be developed in the next 10 years.

He also told LiveScience science magazine: 'But, according to what we know today, the least ethanol and gasoline fuel, is not good for public health, perhaps even worse. Personally, I think there are other technologies that we can apply instead of using internal combustion engines. These technologies allow the creation of engines whose emissions are not harmful to human health. For example, battery engines use solar or wind power. '
