  A 2010 summary by the International Plant Nutrition Institute (IPNI) indicates the incidence of low sulfur levels in soil tests is on the rise.

• Assessment of Mercury in Soils, Crops, Earthworms,

  /research-library?id=7

  Compared to the untreated control treatment, FGD gypsum increased Hg concentrations in earthworms by up to 40%, but none of the increases were statistically significant. If care is taken to remove as much mercury as possible during production of FGD gypsum, it seems mercury should not preclude the use of FGD gypsum as an agricultural amendment.

• Fate of Mercury in Coal ByProducts from DOE's Merc

  /research-library?id=86

  The U.S Department of Energy/National Technology Laboratory (DOE/NETL) research has heled further scientific understanding of the behavior of coal utilization by-products (CUBs) in both disposal and beneficial utilization applications. The following general observations can be drawn from results of the research that has been carried out to date: • There appears to be only minimal mercury release to the environment in typical disposal or utilization applications for CUBs generated using activated carbon injection control technologies. • There appears to be only minimal mercury release to the environment in typical disposal and utilization applications for CUBs generated using wet FGD control technologies.  • The amount of mercury leached from CUB samples tested by DOE/NETL is significantly lower than the federal drinking water standards and water quality criteria for the protection of aquatic life; in many cases, leachate concentrations were below the detection limits of the analytical methods.
