What harm does the pungent smell emitted by inkjet printers have to human health?

A large part of ink pollution is caused by pigment. For these pigments, the particles are relatively small, the adsorption capacity is relatively strong, and they contain some heavy metal elements such as lead, chromium and mercury, which are all toxic. Lead is a metal element, which is the most common in our life. The lead content of a color newspaper is about 2000 micrograms. Lead is the only trace element that the human body does not need. Lead is stable, non-degradable and hinders the formation of blood cells. Therefore, when the lead content in the human body accumulates to a certain extent, people will have mental disorders and have nightmares. Symptoms such as insomnia and headache. For some serious patients, there will be fatigue, loss of appetite, nausea and other symptoms. For lead, it can enter the tissues of the human brain through blood, thus causing damage to the human brain. Children's absorption of lead is several times higher than that of adults, so it has a great influence on infants' intelligence.
