>> One had 380 micrograms of lead per gram of hair, while the other had 258 micrograms. For reference, a normal level of lead in a gram of hair is around 4 micrograms or less. His hair also had 13 times the normal level of arsenic, and four times the normal level of mercury. What is "normal"? Normal for now, or normal for the 17th century? Looking at the hair and makeup regimes of the wealthy, they were all probably soaked in poisons. Arsenic seems more common than garlic, lead used more liberally than salt. If we apply modern standards for poisons, nobody should have survived those times.
