The impact of 4,4 '-dipyridine-1,1' -biphenyl on the environment and human health has been similar to that of foreign bodies in the world in ancient times. Today it is said in ancient Chinese.
The husband of 4,4 '-dipyridine-1,1' -biphenyl, in the environment, if foreign bodies enter the world, its impact should not be underestimated. In the natural environment, this thing may exist between water and soil. Water and soil are the basis for the growth and nourishment of all things. If this thing accumulates in the soil, it may disturb the microecology of the soil. The microorganisms in the soil perform their respective duties to maintain the fertility and vitality of the soil. However, the entry of this thing, or its order, makes the reproduction and metabolism of microorganisms perverse, causing the soil fertility to gradually lose, and the growth of vegetation is also affected by it. Looking at all water flows, if 4,4 '-dipyridine-1,1' -biphenyl enters the Sichuan River, the purity of the water will be polluted. Aquatic species, such as fish, turtles, shrimp and crabs, depend on water to live. This thing may dissolve into water and be absorbed by aquatic organisms, accumulate in its body, damage its viscera, mess with its reproduction, and make the aquatic population gradually thin.
As for human health, it is also threatened by it. People eat grains and drink spring streams. If the food they eat or the water they drink contains this 4,4 '-dipyridine-1,1' -biphenyl, it must enter the body. The internal organs of people perform their duties and coordinate their operation. This object enters the body, or disturbs the function of the internal organs. The lungs control qi, which is used for breathing; this substance may trap qi in the lungs, making breathing difficult. For a long time, lung diseases will occur. The liver controls the release, storing blood and detoxifying; this substance may hinder the release of the liver, causing blood flow to be blocked and poison to accumulate in it. And this substance may damage the nervous system of people, causing trance, memory attenuation, and limb weakness. Or it may affect the human reproductive system, making it difficult to conceive, and the fetus is restless, which will harm the offspring.
Therefore, 4,4 '-dipyridine-1,1' -biphenyl is a hidden danger in the environment and human health, and it cannot be ignored. It should be handled with caution to prevent its harm.
