However, the overall NYC geometric mean is not as high as the geometric mean among German study participants who had mercury amalgams on at least eight teeth (0.89 μg/g; 95% CI, 0.82 0.97).

The German physicist Daniel Gabriel Fahrenheit in 1700 30 produced accurate mercury thermometers calibrated to a standard scale that ranged from 32°, the melting point of ice, to 96° for body temperature.
About 0.4 1 g of sample analyzed using mercury intrusion porosimetry following the German standard DIN 66133.
Another advance in diagnostic medicine occurred when the mercury thermometer, invented in 1714 by German physicist Daniel Fahrenheit, came into general use as a clinical tool in the mid-19th century.
The German HBM commission defined exposure limit values for mercury in blood and urine but not for hair.
The German researchers have demonstrated that exposing neurospheres to known neurodevelopmental toxicants including mercury chloride and methylmercury chloride decreases the number of nerve cells they produce and how far the cells migrate.
In the early 20th century, the German physician Huldschinsky treated patients suffering from rickets with exposure to a mercury-vapor quartz lamp that emitted UVB radiation.
Although these mercury exposure limit values were determined in another setting, UNIDO refers to the German HBM values for categorizing mercury concentrations in human specimens determined in ASGM studies [ 14].
