Chemistry is not good for people s lives, at least 5 points

Toluene, chloroform, tetrahydrofuran and other chemical reagents. How harmful are they to the body?

How big is it? I also want to work in chemical technology in the future. But this kind of work is always unavoidable.

To be exposed to a variety of organic solvents, they are not going to make you lose your life and dull your mind.

The melamine milk powder incident that caused a stir a few days ago is a good example. It warns people to make good use of food additives, and it is also a wake-up call for us that we should also learn some chemical knowledge in life, which will help improve our quality of life. For example, the reason behind myolysis caused by spicy crayfish may be due to oxalic acid and sulfites in the shrimp washing powder, which are good examples.

In addition, if you learn chemistry well and have a basic understanding of the properties of some substances, you can pay more attention to the composition of some things when you go to the supermarket to buy food. Like laundry detergent and dish soap or something, you can know which one is more scientific and less harmful**. Often, what merchants say is clean and dirty and does not hurt their hands is a lie, and many still rely on consumers to identify and judge themselves.

If you master such skills and skills, will it be of great help to improve your material quality of life?

It will cause fetal malformations, which is a decline in the quality of the human body, causing direct harm to the human body and the environment.

The benefits of chemistry to life are as follows:

1. The use of chemical fertilizers and pesticides has increased the yield of crops.

2. The synthesis of new drugs has saved millions of lives.

3. The development of clean and pollution-free energy reduces the pollution to the environment.

4. Chemical calcining of clay can make the house have a beautiful tile surface.

5. Using the principle of hydrogen and oxygen combustion to obtain water, the rocket has the required fuel for launch.

The disadvantages of chemistry to life are as follows:

1. In production, there will be a lot of production wastewater, and bad manufacturers will directly discharge the sewage that does not meet the standards, causing serious harm to the environment and residents.

2. Many chemical products can not be used and will cause environmental pollution.

3. In the newly renovated room, the residue of chemical products will cause harm to the human body.

4. The invention of chemistry has caused great harm to organisms and the environment.

5. The excessive use of additives in food will cause serious damage to the human body.

In many ways:

1. Chemistry has helped us make many new high-performance materials.

2. Chemical reaction plays a very important role in many productions 3. The use of chemical reaction can purify water, decontaminate and so on, which has a great effect on life, and I hope it will help you.

It is possible to blow people up with a mixture of simple reagents, and it is not a dangerous good.

Clothing: Advantage: Clothes are more comfortable, cheaper, more wearable, and better looking.

Disadvantages: Food: Pros: Hybrid foods are highly nutritious and have many varieties.

Disadvantages: Pesticide contamination, genetically modified food is unsafe.

Housing: Pro: The reinforced concrete building is strong and safe.

Disadvantages: destruction of vegetation, apathy of people.

Needless to say, the use of petroleum is as small as rubber, lubricating oil, and as large as aviation fuel, which is convenient and comfortable to travel.

Cons: Pollution. In general, pollution is the disgraceful side of technology, and the key depends on how humans use it.

Pollution of formaldehyde, benzene, toluene and other toxic organic substances in home decoration and clothing printing and dyeing;

Pollution of water bodies by heavy metal ions such as mercury and lead;

Pollution of the atmosphere by sulfur dioxide, nitrogen oxides, etc.

will be harmful to people.
