Objective:
To measure manicurists' exposure to dibutyl phthalate (DBP) at work and to determine whether workplace characteristics influence this exposure. DBP is a reproductive and developmental toxicant in rats and is used in nail polish to hold color and prevent chipping.
Methods:
Pre- and postshift spot urine samples were collected from 40 manicurists. Linear regression compared the relationship between the log of the cross-shift differences in urinary phthalate monoester metabolite concentrations and use of workplace exposure control methods.
Results:
There was a statistically significant cross-shift increase of 17.4 ng/mL in the urinary concentration of mono-n-butyl phthalate, the major metabolite of DBP. Use of gloves reduced mono-n-butyl phthalate concentrations by 15.1 ng/mL below the preshift concentration compared with a 20.5 ng/mL increase if gloves were not worn.
Conclusions:
Manicurists are occupationally exposed to DBP and glove use may minimize this exposure.

Handwashing II: Pre-procedure and Initial Procedure Steps
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury. The nails must be short and clean, without nail paint...
