Once absorbed and circulating, mercury becomes bound to numerous proteins, including keratin. The concentration of mercury in nails correlates with the severity of clinical symptoms. If the nails can be segregated by length, such an exercise can be useful in identifying the time of exposure.
Detecting mercury exposure
Normally, nails contains <1 mcg/g mercury; any amount more than this indicates that exposure to more than normal amounts of mercury has occurred.
0-15 years: not established
> or =16 years: 0.0-0.9 mcg/g of nails
