May acidify its own rhizosphere, which would facilitate absorption by solubilization of the metal [31] [1]: 19, 891, 898 [32] [33] [34] [42] Zn: Trifolium pratense: Red Clover: Nonmetal accumulator. Its rhizosphere is denser in bacteria than that of Thlaspi caerulescens, but T. caerulescens has relatively more metal-resistant bacteria. [31]

[ 19 ] The National Institute for Occupational Safety and Health (NIOSH) recommends that exposures to mercury metal be limited to an average of 0.05 mg/m 3 over a 10-hour workday in addition to a ceiling ...
This observation led, for example, the Food Standards Agency in the UK to propose upper limits of 200 mg/kg. [3] A study showed that 99.5% of the controlled food cans contain tin in an amount below that level. [4] However, un-lacquered tin cans with food of a low pH, such as fruits and pickled vegetables, can contain elevated concentrations of ...
For example, lead may be present where food is grown, raised or processed. The Consumer Reports study stated that metals can be found in sweet potatoes, spinach and carrots, so consumers should ...
