Chemotherapy Agent Exposure –
IAQ-EMF Consulting
Introduction
Cytotoxic chemotherapy agents can pose airborne and dermal exposure risks during HIPEC procedures and drug handling. IAQ‑EMF performed air and surface sampling to assess exposure levels.
Sampling & Methodology
During a HIPEC procedure at St. Vincent Hospital, we collected air and surface wipe samples around pharmacy staff, nurses, and surgeons using validated analytical protocols.
Key Findings
- No detectable levels of Mitomycin C in air or surface samples.
- Recommended exposure limit (0.05 μg/m³) was not exceeded during observation.
- Double gloving and standard PPE practices prevented dermal exposure.
Health Implications & Controls
Even though OELs for chemotherapy drugs are limited, recommendations include using biological safety cabinets, closed-system drug transfer devices (CSTDs), and strict housekeeping to minimize exposure.
Occupational Hygiene Recommendations
We encourage healthcare facilities to adopt:
- Routine environmental monitoring (see our industrial hygiene services page)
- PPE and CSTD procedures
- Training on safe drug handling and spill response
Conclusion
Our study confirms minimal exposure during HIPEC and drug handling with proper techniques. IAQ & industrial hygiene protocols remain critical for safeguarding healthcare staff.

Mitomycin Sampling Results
Results for all samples are shown in detail in the attachment: “Laboratory Analysis Report…” and in the tables shown below.
Results indicate that none of the employees monitored had detectable level of exposure to Mitomycin via air or dermal routes and none exceeded the recommended airborne exposure guidelines for Mitomycin.
Surface Monitoring Results
Environmental sampling consisted of four air samples and six surface samples.
Six surface samples were taken for Mitomycin from numerous surfaces during the course of the HIPEC Procedure covering the preparation, use during surgery and post-surgical procedures.
The six surfaces sampled in the Operating Room were as follows: Surgeon – Dr Arregui’s Outer Glove, on the surface of his inner glove, on the surface of his bare hand; the Surgical Nurse – Shelly, on the surface of her inner glove, on the surface of her bare hand and finally the Decontamination Technician – Tina, on the surface of her outer glove. Mitomycin C, sampled on six surfaces, was not found on any of the surfaces tested.
Mitomycin Air Monitoring Results
Employees of the St. Vincent Hospital in Indianapolis, Indiana were monitored for Mitomycin exposure on February 17, 2009. Four air samples were taken in the breathing zone of key personnel during the HIPEC Procedure.

Discussion of Results
Results are based on the data gathered from two separate HIPEC procedures approximately two years apart. Air monitoring results indicate that none of the employees monitored during the procedure on February 17, 2009 had detectable levels of Mitomycin in the four air samples or on the six surfaces tested, including the gloves and bare skin (palm) of surgical personnel. As well, none of the surfaces tested in February 2007, including the palm, had detectable quantities of Mitomycin. The recommended exposure limit (REL), 0.05 micrograms per cubic meter of Mitomycin was not exceeded.
Mitomycin
Results indicate that no detectable quantities of surface or airborne of Mitomycin were found in the operating room during this procedure. Mitomycin in its purest form is a solid powder cake. As a solid material at room temperature, it has an infinitesimally low vapor pressure, so in essence it will not evaporate. In its aqueous dextrose solution (dissolved solid) as used in HIPEC, it has not been known to aerosolize during its normal and routine application. Thus it is very unlikely to be inhaled in any form. The need for any local exhaust ventilation (such as portable smoke evacuators) is superfluous and unnecessary and may take up valuable floor space.
LCMS
The laboratory used a method of analysis known as liquid chromatography-mass spectrometry (LCMS).[5] This method has a limit of detection (LOD) for Mitomycin that ranged from 2.20 micrograms per cubic meter to 0.22 micrograms per cubic meter based on sampling times ranging from 24 minutes to 4 hours and 4 minutes. Any quantity below the limit of detection would be reported as “not detected” though in theory it may be present. At this time there are no readily available analytical methods known to this researcher with a lower level of detection.
On surfaces in close proximity to the operating table, Mitomycin was not detected. Additionally, no “breakthrough” of Mitomycin was seen during the use of the Biogel™ gloves. They appear to offer adequate protection of the skin surface.
