    For humans, the OSHA [9] workplace permissible exposure limit (PEL [10], 8-hour-time-weighted average) for chromic acid and hexavalent compounds is 0,05 mg/m (carcinogen). For bivalent and trivalent chromium the PEL is stated to 0,5 mg/m (Olsen, 2004). Crops contain on average 0,2 – 1 mg/kg chromium in dry mass

    The Santa Rita ore has highly variable Pt + Pd contents (up to few ppm) and average of about 200 ppm for the total mineral resources of the open pit. The ore zone is located within the progressive transition from dunite, harzburgite, orthopyroxenite and wesbsterite, a characteristic feature of the upper portion of

  • radioactive mineral samples: Topics by radioactive mineral samples: Topics by

    Most of the detectable radioactivity is due to the presence of radium-226, a uranium daughter product, but at least one spring precipitate contains abundant radium-228, a thorium daughter product. The 5:1 ratio of radium-228 to radium-226 suggests the proximity of a vein-type deposit as a source for the radium

  • Environmental contamination from trace elements in coal Environmental contamination from trace elements in coal

    Coal-waste piles are generally formed from preparation (tipple) plant refuse and mine- development wastes by dumping them in a disposal area. The dumping may be down the side of an embankment, in which case the larger rocks roll to the bottom, and the finer refuse stays at the top, producing a segregated mass
