AB  - A simple and rapid extraction procedure was developed for determining aldehydes 
      in rainwater samples. This extraction technique involved the use of 
      micro-solid-phase extraction in which the sorbent was held within a polypropylene 
      membrane envelope, followed by high-performance liquid chromatographic analysis. 
      Aldehydes such as formaldehyde, acetaldehyde, propionaldehyde and valeraldehyde 
      were used as model compounds. Extraction conditions were optimized. The method 
      linearity ranged between 0.5 and 50 mugl(-1) with the correlation coefficient of 
      0.987-0.999. The relative standard deviations (RSDs) of the method ranged from 7 
      to 12%. Method detection limits were in the range of 0.07-0.15 mugl(-1), which is 
      lower than those previously reported for solid-phase microextraction combined 
      with gas chromatography-mass spectrometric techniques. The proposed extraction 
      technique was used for determination of aldehydes in rainwater samples to 
      demonstrate the applicability of the method.
