Reviews

  • A Good Overview (though slightly back-dated): Quantitative assessment of worldwide contamination of air, water and soil by trace metals [1]
  • A summary of Pollutants from the EPA [2]

Cadmium

  • MCL: 5 ppb
  • MCLG: 5 ppb
  • Known Carcinogen
  • Cadmium Contamination Sites

Toxicology. 2001 May 28;163(1):23-8. DOI:10.1016/s0300-483x(01)00367-5 | PubMed ID:11376862 | HubMed [Ishihara01]
Plachimada, India: [3]
    • statistics on Pb, Cd, Cr levels in well water surrounding a Coca-Cola plant (2006)
    • pictures too :)
  • Most recent(June06) paper on e.coli bioaccumulation of Cd
  1. Deng X, Yi XE, and Liu G. Cadmium removal from aqueous solution by gene-modified Escherichia coli JM109. J Hazard Mater. 2007 Jan 10;139(2):340-4. DOI:10.1016/j.jhazmat.2006.06.043 | PubMed ID:16890348 | HubMed [Deng06]

Mercury

  • MCL: 2 ppb
  • MCLG: 2 ppb
  • 20 ppb makes the fish mercury buildup significant
  • Polluted sites
    • Onondaga lake [5] [6] [7]
    • Salt Plains National Wildlife Refuge [8]
  • Detection (to assess our system):
  • Promoter
