What does the phosphorus chemical industry mainly do?

(Citation) The phosphate chemical industry includes two sub-industries: phosphate fertilizers and phosphates. In the global consumption structure of phosphate rock, about 70% is used in agriculture, while the remainder is used for the production of yellow phosphorus, phosphoric acid, and other phosphate-based products. In addition to being used in agriculture as phosphate fertilizers, phosphorus-containing pesticides, and feed for poultry and livestock, phosphorus is also widely utilized in detergents, metallurgy, machinery, mineral processing, drilling, electroplating, pigments, coatings, textiles, printing and dyeing, leather processing, pharmaceuticals, food, glass, ceramics, enamel, water treatment, refractory materials, building materials, daily chemical products, paper manufacturing, ammunition, flame retardants, and fire extinguishing agents. With the advancement of technology, high-purity and specially functional phosphorus chemical products are being increasingly utilized in fields such as cutting-edge science and the defense industry, giving rise to a large number of new products, including electronic and electrical materials, sensor components, ion exchangers, catalysts, artificial biomaterials, solar cell materials, optical materials, and so on. As phosphorus chemical products continue to penetrate more industrial sectors, particularly in advanced science and emerging industries, phosphorus chemistry has become an important industry within the national economy. Phosphorus chemical products are playing an increasingly important role in various aspects of people’s lives, including clothing, food, housing, and transportation.

Since it is the chemical industry, occupational diseases are bound to occur, but I’m not entirely sure about the specifics. I hope everyone can participate and discuss this together.

There is a very high level of dust in the workshop where compound fertilizers are produced, and this dust is corrosive. Is it effective for the workers there to wear masks while working to protect their health?

The production process determines the level of pollution (of course, poor management is another factor). The main pollutants include dust, noise, acids, fluorine, and ammonia; among these, dust and noise are inevitable. Examples include sulfuric acid production from pyrite, sulfur, and flue gas; among these, the use of pyrite for sulfuric acid production has been banned in many places due to its severe environmental impact. Reports indicate that in areas affected by such production facilities, entire forests suffer from withering as a result of the wind direction. What was said on the 4th floor about there being a lot of dust in the compound fertilizer workshop is true, but the claim that \"all of that dust is corrosive\" is somewhat one-sided. Also, the noise in the ore processing and compound fertilizer production workshops is another major occupational disease. I believe that fluoride in phosphoric acid, as well as ammonia in the compound fertilizer workshop, are factors that cannot be ignored. Finally, what needs to be discussed is corporate management, namely how a company invests in controlling these indicators.

Reply to 5# weng200200: Is there a lot of dust in the phosphorus chemical plants? What is the impact on the environment of producing high-purity phosphorus chemical products such as yellow phosphorus, phosphorus pentoxide, phosphoric acid, polyphosphoric acid, calcium hydrogen phosphate, sodium tripolyphosphate, sodium hexametaphosphate, sodium pyrophosphate, trisodium phosphate, and disodium hydrogen phosphate?

Hehe, I also need information in this area. Comrades, please share your suggestions!
