Summary Studies were conducted to evaluate the uptake of mercury by wheat (Triticum aestivum L. runar) and beans (Phaseolus vulgaris L. marshal) growth on an oxisol with different levels of 2-methoxyethylmercury chloride (Aretan) and mercuric chloride. Dry matter and grain yields of wheat were little affected by either Aretan or mercuric chloride, although Aretan at 50 mg Hg/kg soil delayed germination by four to five days. Germination of beans grown with both compounds at the 50 mg Hg/kg soil failed completely, even after repeated sowing. Yields were somewhat, though not significantly, decreased by mercury chloride up to 5 mg Hg/kg soil. The concentration of Hg in wheat straw and grain increased significantly with increased levels of Aretan and HgCl2 application, with more Hg taken up by the plants grown with HgCl2 than with those grown with Aretan. Translocation of Hg to grain was greater in the plants grown with HgCl2. The concentration of Hg in bean straw, but not grain, increased significantly with increasing levels of Aretan and HgCl2 application, and was greater in plants grown with HgCl2. Translocation to grain was low, with little difference between plants grown with Aretan or HgCl2.
