“…The Hg values in the grass stems ranged from 3 to 8 ppm Hg for the maximum values. The values are within the ranges others have observed in several trees and a grass: 5.23 ppm in Abies needles from trees in 85 ppm Hg soil (Barghigiani 1992), 1.5 ppm in pine needles (Pinus nigra) and 1.04 ppm in spruce needles (A b i e s a l b a) from trees in 85 ppm Hg soil (Barghigiani 1994) and 4.83 ppm in shoots from Cynodon dactylon in 22 ppm Hg soil (Lenka et. al.…”

“…They also found root concentration of Hg was inversely related to the subterranean organ size. Barghigiani and Bauleo (1992) found the mercury levels in Abies alba needles correlated with soil Hg levels. Cocking et al (1995) make the statement that it is difficult to predict Hg levels in vegetation of Hg-contaminated terrestrial ecosystems due to the large number of variables.…”

Vegetative uptake of heavy metals in plants growing in contaminated areas has received attention since the 1960's for a variety of reasons. The accumulation of heavy metals by agricultural crops is a public health concern. Vegetative sampling has been used to biomonitor soil levels of heavy metals from natural and anthropogenic sources (Rasmussen 1994). Studies of uptake of heavy metals by plants from mining areas has led to some understanding of heavy metal tolerance in plants and mechanisms; by which tolerance occurs (Antonovics et al. 1971, andBaker and Brook 1989).Mercury loss associated with the amalgamation process of gold recovery from stampmill mining in Idaho has produced occasional high levels of mercury contamination. Mercury and arsenic as high as 200 ppm and 2000 ppm respectively were measured in an abandoned stampmill site near Atlanta, ID (elevation 5,500 ft, montane zone).This study is a survey of root, stem, and leaf accumulations of Hg in several shrubs and grasses growing at the abandoned stampmill site near Atlanta. An attempt was made to correlate plant uptake with Hg levels in the soil. Also the question was examined, "do different plants show distinctive differences of uptake levels and patterns of Hg distribution?" MATERIALS AND METHODSThe study site was bordered on the north and west sides by the Middle Fork of the Boise River. A road formed the east border. The south end of the study site was covered with thick brush and a steep rise just beyond a small creek that ran into the Middle Fork. A grid was formed by running north-south transect lines the length of the area and east-west transect lines the width of the area. This formed 1.55 quadrates, measuring about 13.1 meters on a side. Soil samples were collected at a depth of 15-20 cm below the surface from the approximate center of each quadrate. If a quadrate had high levels of Hg (>5 ppm) additional samples were obtained from that quadrate. All soil samples were stored

“…Rosemary and sage could be mercury accumulators because they are evergreen and are thus exposed to Hg for long periods. It is also interesting to point out that, near the Abbadia mine, beets, lettuce, rosemary, and sage had Hg concentrations, as dry weight, close to those of broom twigs and pine needles (Barghigiani and Bargagli 1987) and spruce needles 4-6 years old (Barghigiani and Bauleo 1992). This was also true for beets collected near the Siele mine (station 4).…”

“…Similar results were observed in chicory, while lettuce was less contaminated. At the stations far from mercury contamination sources, the analyzed plants had lower mercury values than brush or woody plants such as broom, pine, and spruce (Barghigiani and Bargagli 1987;Barghigiani et al 1988;Barghigiani and Bauleo 1992). Hay, rye, and barley had low Hg contents, unlike wheat, corn, and fodder plants which were collected and analyzed when the mines were still active, with mercury levels ranging between 0.1 and 1 Ixg/g dry weight and higher (Galoppini and Pelosi 1972).…”

This work assesses mercury in agricultural products of Mt. Amiata (central Italy), an area characterized by the presence of important HgS deposits, and by intense mercury mining and smelting activities in the past. The results show that at some sampling stations the Hg contents in vegetables, meat, and other products were high. The relations between agricultural products, soil and air mercury concentrations are discussed, and consideration is given to possible dangers to human health for residents of the Mt. Amiata area.

Abstract-The uptake, distribution, and subsequent emission of mercury to the atmosphere were investigated in five plant species ( [Labill]) with different ecological and physiological attributes. Transfer coefficients for mercury in the soilplant system were calculated. Plant-to-atmosphere emissions of mercury were determined using a controlled environment gasexchange system and ranged from 10 to 93 ng/m 2 /h in the light; emissions in the dark were an order of magnitude less. Transfer coefficients for mercury within the soil-plant system increased acropetally (root-to-leaf axis) by orders of magnitude. Estimated mercury emissions from plants in the Carson River Drainage Basin of Nevada over the growing season (0.5 mg/m 2 ) add to the previously reported soil mercury emissions (8.5 mg/m 2 ), resulting in total landscape emissions of 9 mg/m 2 . For L. latifolium, 70% of the mercury taken up by the roots during the growing season was emitted to the atmosphere. For every one molecule of mercury retained in foliage of L. latifolium, 12 molecules of mercury were emitted. Within this arid ecosystem, mercury emissions are a dominant pathway of the mercury cycle. Plants function as conduits for the interfacial transport of mercury from the geosphere to the atmosphere, and this role is undervalued in models of the behavior of mercury in terrestrial ecosystems and in the atmosphere on a global scale.
