According to experts, at present, printing ink is basically used in China, and a major problem of ink pollution lies in pigments. These pigment particles are very fine, have strong adsorption capacity, and contain heavy metal elements such as lead, chromium, cadmium and mercury, all of which have certain toxicity. Take lead for example. A page of color newspaper contains about 2000 micrograms of lead. Lead is a trace element that the human body does not need. It is stable and non-degradable and hinders the formation of blood cells. When the lead in the human body accumulates to a certain extent, there will be symptoms of chronic poisoning such as insanity, nightmare, insomnia and headache, and in severe cases, there will be symptoms such as fatigue, loss of appetite, nausea, abdominal distension, abdominal pain and diarrhea. Lead can also enter brain tissue through blood, causing brain damage.

Of course, you feel a smell, which may be psychological. I suggest you find some colleagues to feel it. If everyone says it smells, it will still do some harm to the human body. It is recommended to open more windows for ventilation.
