Are the effects of chemical agents on the body serious?

I think it's a chemistry student who asked this question, so I'll give it a strong answer as a chemistry student. Don't be afraid, don't be scared by the term chemical reagent, the real toxic chemical reagent will not be easily taken out for you to use, and as long as the operation is standardized, the danger can be reduced. And, just when it gets on your hands, rinse it well.

The first point is that the experimental reagents used in daily experiments are often not toxic, not into the eyes, but just on the hands, just rinse. Generally speaking, potassium permanganate is a dangerous drug, but it can only cause discoloration when it comes to hands. Teachers don't care about you.

But if it is potassium dichromate, there will not be much of a problem, and there is no problem with timely flushing.

The second point is that talking about toxicity aside from measurement is nonsense. No matter how toxic the agent is, there will be no problem if it does not reach the measurement, and if it is really a particularly dangerous reagent, the teacher will repeatedly emphasize it, and tell how to protect it and how to deal with it in case of accidental contact. Volatile toxic reagents can be carried out in a fume hood.

The third point is to standardize operations. If your operation is regulated and you wear a white coat or something, then the risk is minimized. The waste liquid is poured into the waste tank.

Be careful not to touch it. The reagent is carefully protected from the entrance of the eye. It is forbidden to eat in the laboratory, and open flames are prohibited.

All in all, don't worry too much about dangerous reagents. In daily experiments, you will not be allowed to use too many reagents, even if it is a particularly dangerous item, and it will not be a big problem to take protective measures.

The effects of chemical agents on the body are very severe, and may cause the function of certain organs in the body to deteriorate, which may cause death.

The research and invention of chemical reagents can improve people's lifestyles, but the harm to people is very great. There are some chemical agents that are deadly.

Long-term exposure to chemicals still has a certain impact on the body, including the respiratory system, nervous system and digestive system.

This is too much, and general organic solvents are not good for the human body.

There are also inorganic, corrosive, and volatile.

The experimental equipment seems to be okay, and I haven't touched anything too dangerously at the moment.

Nanjing Beiden can do one-stop distribution.

There is a professional store for reagents on the first floor of the medical building at No. 71 Huaihai East Road, Xuzhou, which is very authoritative in Xuzhou and very good.

There is a chemical glass metrology store on Weihai West Road, and a little east of the second courtyard is that our unit has bought it from there before, and there are more reagents.

Chemical reagents**The store has everything You can**collect Chongqing Drip Experimental Instrument is a store specializing in chemical reagents, biochemical reagents, experimental instruments, and glassware.

The Xingtai area should be the most complete and cheapest in the east and west of Maosen, which is at the east end of Quannan Street.

Your idea is good, but be sure to be safe!

Opposite Baihe Park, a company specializing in selling chemical equipment, at the intersection of Jianshe Road and Cuibai Road.

This is too much, depending on what kind of instrument or reagent you need, such as imported reagents, you can find Beijing Baoxidi. [email protected] instrument southeast instrument is good.
