Guidance for Air
The following guidance was developed by the Minnesota Department of Health (MDH) at the request of the MDH Site Assessment and Consultation Unit and the Minnesota Pollution Control Agency (MPCA). For more information, contact the Health Risk Assessment Unit.
Note: This information pertains to the chronic Risk Assessment Advice (RAA) for tetrachloroethylene only. MDH also has developed an acute Health Risk Value (HRV) for this chemical.
Tetrachloroethylene (Perchloroethylene): Interim Chronic Risk Assessment Advice
March 3, 2011
CAS number: 127-18-4
Endpoints: Cancer, Nervous System
Chronic Value(s): 20 ug/m3 (cancer); 100 ug/m3 (non-cancer)
MDH completed a review of the available information on the health risks of tetrachloroethylene and, based on this review, MDH reaffirms that RAA first developed in 2006 is protective of public health. Generally, RAA may contain greater uncertainty than HRVs and Health-Based Values because the available information is more limited.
