Anatomy labs at medical schools utilize a formaldehyde solution to preserve cadaveric specimens for dissection. Having gone through this process I know how messy it can be. Even after washing scrubs with detergent I wonder if there are trace amounts of residual formaldehyde that can be somehow quantified. I suspect the result would be extremely low if any. Can anyone think of a way to do this? Perhaps extracting water from a freshly washed scrub top and submitting for NRM spectroscopy?
