heavy metals complexing with chromate

[nicholas giardino]

     Does any one have any health, toxicology, target organ effects, etc. 
     for:
             ACGIH TLV mg/cu.m (This is only additional information)
     SrCro4  0.0005
     CaCrO4  0.001
     ZnCrO4  0.01
     BaCrO4  not available
     PbCrO4  0.012
     
     Also, any toxicological information on the metals themselves would be 
     most helpful.
     
     Thanks,
