🏥😷 Inhalation health benchmarks and references

Hierarchy of sources

Benchmarks are selected using the following hierarchy:

1. Minnesota Department of Health
   • Risk Assessment Advice
   • Health Based Values
   • Inhalation toxicity values in the ISV spreadsheet
   • Health Risk Values - SONAR (PDF)
   • MDH site specific values
2. EPA IRIS
3. Cal EPA RELs & PDF Table
4. CDC ATSDR
5. EPA PPRTVs

2018-19-07

• Benzo(a)pyrene(BaP) added inhalation non-cancer RfC of 0.002 from IRIS

2018-04-04

Changes

• Trichloroethylene(79-01-6) acute value updated to MDH RAA from 2,000 to 6 ug/m3.

2018-02-01

Changes

• Arsine(7784-42-1) cancer IHB removed. Was previously assumed equivalent to Arsenic.

2017-04-01

Changes

• MPSFs for Lead and Lead compounds updated to align with IRAP modeling results. This corrects for the previous modeling using the default Henry's Law constant assigned to inorganic metals.
• All inhalation health benchmarks rounded to 2 significant digits
• All of MDH's HRV and HBV chronic inhalation health benchmarks rounded to 1 significant digit, except for benzene
• Tetrachloroethylene (Perchloroethylene) non-cancer IHB updated from 100 to 15 ug/m3 per MDH guidance dated July 2014
• Napthalene cancer IHB set to 9 ug/m3 per MDH guidance dated Feb. 2017
• Ethylene Oxide cancer IHB set to EPA's IRIS value updated Feb. 2017
• Trimethylbenzenes non-cancer IHB set to EPA's IRIS value updated Sept. 2016
• Ethanol specific risk values identified in references, rather than on separate rows
• Chromic acid mists and dissolved Cr(VI) aerosols CAS# changed to 18540-29-9-aer

Bug fixes

• Benzo(k)fluoranthene CAS# changed to 207-08-9
• Furfural (ethanol) CAS# changed to 98-01-1
• Formic Acid (ethanol facility) CAS# changed to 64-18-6
• Ethylene dibromide (Dibromoethane) changed to Ethylene dibromide (1,2-Dibromoethane)
