My boyfriend is engaged in highway section measurement and usually comes into contact with some asphalt. What effect will it have on his health? How to take effective protective measures?

I study asphalt modification and asphalt pavement.

Your question is also a problem that I have been worried about, and I can give you a clear and detailed answer.

1. Look at your boyfriend doing highway section measurement. I don't think this has much impact on your health.

2. Petroleum asphalt is harmless to people and basically non-toxic. However, if asphalt is modified, it will do great harm to people in this process, because many modifiers are harmful to people's health. For example, I dare not touch these things now. When I directly checked the toxicity of those modifiers, the explanation was that they were extremely toxic.

3. If the finished product is modified asphalt, it will not be harmful to people as in the process of asphalt modification. Your boyfriend should be exposed to the finished modified asphalt the most.

4. In the process of asphalt recovery or oil-stone ratio detection, there is an experiment called extraction test. Ask your boyfriend if he has done this experiment. This experiment is basically unnecessary now, and the combustion furnace method is used. Because the solvent used in the extraction experiment is trichloroethylene, which is toxic and has an impact on people's fertility, I remember that when I was on a business trip at the construction site, I saw many experimenters doing this experiment in the construction unit, and each group was subsidized by 15 yuan, and they were still the kind of old masters who already had children. Because it is toxic, not many people are doing this experiment now, so the combustion furnace method is used instead.

Generally speaking, asphalt is non-toxic, but many polymer materials such as modifiers and solvents are used around asphalt, many of which are highly toxic, mainly in modification and testing. At present, only extraction test and asphalt modification are toxic.

It's no use wearing a mask If you are afraid, you'd better wear a gas mask. I used to wear it before, but it was very uncomfortable, just when I was doing asphalt modification. But not during construction.

7. Don't worry too much. Although it is toxic in some links, it is not a big problem, and its carcinogenic and reproductive effects are not as serious as we thought. You relax.

8. Finally, a gossip, a joke on our side, is that it is easy for girls to make asphalt. What asphalt is acidic affects gender. This is not necessarily based on science. That sounds interesting.
