My professor in nuclear chemistry, Torbjörn Westermark, was to my knowledge, 
the first in the world to determine mercury in birds feathers (as controls, 
samples from museums were used). The technique was probably neutron 
activation. The time may have been around 1959 (my guess). It is good that 
mercury (and its alkyl forms) was brought up - it was indeed a big problem 
here with relations to the acidification of lakes (a number of fish species 
in many lakes - perhaps with emphasis on pike - couldn't be eaten for many 
years).
