Bert van Bavel developed a blood test protocol for Safe Planet, a global awareness campaign established by the UN Environmental Programme that could be used to monitor the levels of these toxic chemicals in the global population. He designed a test to measure 'body burden' – that's the amount of these persistent synthetic chemical pollutants that accumulate in the body. Since 2010, this test has been carried out on more than 100,000 people around the world, across Europe, North and South America, Africa and Southern Asia.
