She let them take a blood sample from her and test the blood to see which chemicals were in her blood stream. They found an alarming number of dangerous chemicals in her blood, and she - together with Greenpeace - confronted the large Finnish chemical company, Finnplast at their headquarters in Porvoo, Finland.

She gave them a sample of her blood in their campaign to "return the problem to the sender" - i.e. to combat the chemical companies which include dangerous substances in their products, which ultimately get absorbed into the bloodstream.
