[Lead-contents in mushrooms (author's transl)].
The lead-contents of canned and fresh mushrooms were analyzed by photometric determination after dry ashing and dithizone extraction. The average lead-content was found to be 0.49 ppm with extreme values of 0.10--1.0 ppm on fresh-weight basis resp. 5.5 ppm (2.0--13.5 ppm) on dry-weight basis. It appears that lead content increases with the size (age) of the mushrooms; the influence of canning upon the lead content is not yet finally clear, it seems, however, as if canning process has a lesser influence on the lead content than the size (age) of mushrooms.
