Abstract This paper designed a series of easy, hands-on experiments that inquire into the properties of tattoo inks of varying quality, such as heavy metal elements, particle size, coloration and effects on cell activity or plant growth. The findings showed that tattoo inks had potential health risks, and the health risks of low-grade inks were greater than those of high-grade inks. The experiments led students to understand chemistry in life and cultivate scientific risk decision-making ability.
