Working in this environment for many years, if there is no perfect protective measures and firm awareness of protection, there will be big problems. A big problem of ink pollution lies in pigments. These pigments are very fine and have strong adsorption capacity, and contain heavy metal elements such as lead, chromium, cadmium and mercury, all of which are toxic.
Extended data
Ink contains a lot of heavy metals such as lead and mercury, mainly from pigments and additives in ink. Some aromatic solvents, such as toluene and xylene, are often used in printing ink, which will volatilize into the air and pollute the air with the drying of the ink, and it is very toxic, which will cause cancer and damage the health of printing workers.
Ink also contains a toxic substance called polychlorinated biphenyls, whose chemical structure is similar to DDT. If you wrap food in a newspaper, this substance will penetrate into the food and then enter the human body with the food. The chemical properties of PCBs are quite stable. Polychlorinated biphenyls (PCBs) are easily absorbed and accumulated after entering the human body, and it is difficult to excrete them.
