Exposure to perchlorethylene, especially for
dry cleaning workers and for people living near dry
cleaning shops, could lead to several diseases and
disorders. This study examines the value of solidphase
microextraction (SPME) for sampling perchlorethylene
in the atmosphere of dry cleaning shops.
Carboxen/polydimethylsiloxane (CAR/PDMS) in
0.5-cm retracted mode was selected. There were no
significant differences between sampling rates at different
temperatures (range of 20 to 30 °C) and air
velocities (2 to 50 cm/s). On the opposite, relative
humidity (RH) had a significant effect on sampling
rates. Method reproducibility was realized in the laboratory
and field conditions and was 6.2 % and 7 to
11 %, respectively. Repeatability was also determined
as 8.9 %. Comparison of the results according to the
American Industrial Hygiene Association exposure
assessment strategy showed the SPME sampler yields
more conservative results in comparison with traditional
standard method.
