He was surprised to find relatively high levels of a chemical known as oxychlordane which is normally found at lower levels than DDT and more often in the US and Asia than in the UK. The pesticide chlordane was banned in the UK in 1981, just a year after I was born. Once in the body, it's metabolised into oxychlordane which was found in my blood at only 5% of the levels present in the population during the 1980s. But the 'half life' of this chemical – that's the time it takes for it to halve in concentration in my blood – is about 30 years. So not only was it probably passed to me via the womb, but I will have inadvertently passed this toxic legacy on to my own two children.
