[Types of exposed chemicals]
Different chemicals have different terators, which will act on different tissue organs, so it cannot be generalized.

Pregnant women exposed to a certain concentration of phthalate can cause premature birth and embryonic development, or when the fetus is bornThe weight is too light.
Benzhenone chemicals mainly exist in sunscreen products as a chemical sunscreen.However, if diophenone is touched during pregnancy, it may cause expectant mothers to be allergic to light, and it may also affect the growth and development of the fetus.
