| Atmospheric deposition of mercury is a contributing factor to the bioconcentration of this metal in the environment. This study determined the uptake of mercury in the common bean, Phaseolus vulgaris. The plants were grown in a controlled environment and were dosed with water containing mercury concentrations of 0.5, 1, 2, and 5 mg/L. The plants developed into the mature stage and reproduced, yielding bean pods. Soil, water eluent and all parts of the plants including the leaves, stems, roots, and bean pods were analyzed. Mercury concentrations were analyzed by cold-vapor atomic absoption spectrometry and tissue samples examined by scanning electron microscopy. Exposure and consumption of mercury can lead to detrimental effects on living organisms. |
