Christel Nielsen’s research focuses on how chemicals in our environment affect our health – including the chemicals which make up tattoos.
She led a team at Sweden’s Lund University who conducted a study which linked cases of malignant lymphoma diagnosed and people with tattoos over a ten-year period.
Christel joins Jim to tell us all about the study and how society can ensure tattoos, which she says are a legitimate form of self-expression, can become safer.
