I was fascinated by the idea of “body burden”.  I did some more digging about post-mortem body burden and bioaccumulation. I had literally never heard of the term before.
Body Burden and Bioaccumulation (From Lasting Health)
Chemicals vary widely in the timescales it takes for their potency to reduce. Substances such as alcohol break down quickly and are dispelled from the bloodstream within 12 hours, but synthetic chemicals take much longer, up to many years in some instances. Exposure to chemicals such as PFAS can persist in our body for many years; it’s described as a “forever chemical”.
Over time, and with repeated exposure to chemicals, the effect of multiple chemicals entering the body can lead to a bioaccumulation of chemicals that can become toxic to our health, contributing to feeling unwell, and a wide range of illnesses and disease.
