Mercury in marijuana
Siegel BZ, Garnier L, Siegel SM. 1988. Mercury in marijuana. BioScience. 38(9):619-623
Plants are known to accumulate metals and metalloids from the environment. Often the metal content of vegetation is used to indicate local ore deposits or to detect pollutants (Cannon 1960, 1971, Vinogradov 1959, Warren et al. 1968). Mercury and its inorganic derivatives in plants have become increasingly recognized as coming from a variety of natural sources including thermal springs and volcanoes (Siegel and Siegel 1982, 1987a, Siegel et al. 1985, 1987). Without minimizing the significance of anthropogenic release of mercury into the biosphere by fossil fuel burning (Andren and Nriagu 1979) or the microbial formation of organic mercury compounds (Jensen and Jernelov 1969), abundant evidence now exists for natural volcanic and geothermal sites as major sources of environmental mercury available for uptake by vegetation (Phelan-Kotra et al. 1983, Siegel and Siegel 1984, 1987b, United States Geological Survey 1970, Varekamp anmd Buseck 1986).
