Decabromodiphenyl ether: federal lists and state cleanup levels
- CAS 1163-19-5
- 1 federal list
- 1 state
CAS 1163-19-5 is on one of the three federal lists this handbook carries from Title 40 of the Code of Federal Regulations, Parts 300 to 399, revised as of July 1, 2025: the toxic chemicals for release reporting (40 CFR 372.65). That list's rows for it are below as the regulation prints them. CAS 1163-19-5 is in the cleanup-level tables of one state in this handbook: Florida (Decabromodiphenyl ether). Its numbers are below as its agency prints them. A state that lists the substance under another CAS number, or without one, is not shown here.

- Chapter 62-777 CTLs
- February 2005
For Decabromodiphenyl ether, DEP's cleanup target level tables print 7** ug/L as the groundwater criterion, 840 mg/kg for residential direct exposure to soil and 9.3 mg/kg for soil leachability based on groundwater.

** = Groundwater CTLs for class C carcinogens with no cancer slope factor were developed using the reference dose divided by a factor of 10, as described in the February 2005 'Final Technical Report: Development of Cleanup Target Levels (CTLs) for Chapter 62-777, F.A.C.'
For the federal lists the regulation governs. This page copies the Code of Federal Regulations' annual edition revised as of July 1, 2025, which is kept up to date by the Federal Register; amendments published there since that date are not shown. This page is a reference copy and not a reporting decision. Check the current regulation before relying on a value.
A list with no section on this page has no row with this CAS number. That alone does not put the substance outside the list: the lists also have entries with no CAS number (broad classes, chemical categories, waste streams), which a page filed by CAS number cannot show.
Each agency's own publication governs: its current table, or the published rule where the agency says so. This page is a reference copy and not a cleanup decision. Check each agency's page before relying on a value.
