摘要：

Concentrations of steroids and inorganic ions were measured in waste water of an aerated sand trap as well as in aerosol particles emitted from this tank at the waste water treatment plant (WWTP) of Bayreuth, Germany, in January and February 2003. The investigations comprised seven sterols, two estrogens, and several inorganic ions. Since an appropriate method for the determination of sterols in waste water was not available, a new method based on solid phase extraction was developed. The concentrations of the sterols coprostanol and cholesterol amounted to 30-180 mu g 1(-1) in waste water and to 400-5000 pg m(-3) in aerosol particles. All other sterols were present in markedly lower concentrations. The mean concentrations of the two estrogens estrone and 17 beta-estradiol were about 165 pg m(-3) in aerosol particles. The steroid concentrations in both waste water and aerosol particles varied greatly over time, however with the exception of coprostanol, no clear correlation was detected between concentrations in waste water and aerosol particles.
