Metal: Nickel (Ni)
Medium: Freshwater
Test Type: Acute/Chronic
Organism: n/a
Endpoint: n/a
Effect: n/a
2015-01-07: Name changed from "Ni_Daphnia_pulex-2014-10-14.dat" to 
   "Ni_all_studies_calibration_2015-01-07.dat".  BL-Ca and BL-Mg logK values were calibrated 
   with multiple species, using data from multiple studies.  
    
2016-01-28: Name changed to "Ni_all_studies_calibration_2015-10-31.dat", based on the parameters 
   being calibrated in "Ni_calib_write.dat" on Oct 31, 2015.  
   
2019-08-02: Name changed to "Ni_all_studies_calibration_2015-10-31_toxic_carbonates.dat".  Added 
   toxic BL species of BL-NiCO3 and BL-NiHCO3.  Trying to get a "hook" of increased toxicity at 
   high pH (>8.4), as is seen in many Ceriodaphnia dubia datasets. Related to major ion toxicity.
   Added in the critical accumulation table from NiPERA's FW reconciliation project.
   For NiPERA. After playing with it a little, eliminated NiCO3 as a toxic species and just left 
   NiHCO3 - the range of pH values where you see the NiCO3 effects are too high for us to have any 
   data, so probably best not to make any assumptions there.
   
2020-02-04: Name changed to "Ni_all_studies_calibration_2020-02-04_toxic_carbonates.dat". CA for
  C. dubia chronic reproduction EC20 endpoint was updated to reflect the change to the parameter 
  file (introducing the toxic bicarbonate species).
  
2021-03-03: Updated the thermo database to NIST_20170203.dbs, which includes the 
  calibrated Ni-FA binding constant and binding constants for carbonate complexes 
  have been corrected to the NIST/IUPAC values rather than WHAM V defaults.
  
2021-04-06: Updated the critical accumulation table from "NiPERA/FW 
   Reconciliation/Data/R_Scripting/Data_Files/02_PFile_Critical_Table_NiHCO3.csv", dated 2021-04-06 12:24PM.
   These are the as-submitted values from the Ni BLM manuscript. 
   
2022-03-23: (KEC) Added quotes where appropriate in the critical table. (e.g. "juvenile, 16-24h" 
   needs quotes to parse correctly b/c it's comma-delimited), and removed duplicated references. 
   Note: this parameter file has >100 rows in the critical table, which is too many for versions 
   2.48 and prior. I fixed this in version 2.49 build 2022-03-23.
   
2024-04-10: (KEC) Removed S as a component - its reactions are not in the thermo database and it
   was causing confusion for BC and CCME software users.
