This modified method is simple, as accurate as is necessary for field work, and can readily detect heavy metals in concentrations as low as 0.001 p.p.m. Under favourable conditions, even lower concentrations can be detected by an experienced field man.During the 1950 field season, we have started to refer to this modification in the use of dithizone as the “emulsion” technique, in contrast to the “classical” dithizone methods employed by earlier writers.
