[Determination of atmospheric lead]

The AA. discuss the analytical determination of airborne lead, pointing out the importance of a good standardization of the sampling conditions to obtain comparable data. Results of an experimental study on several sampling techniques for lead in air particulates are reported. The investigated factors were: location of samplers, time and rate of sampling and type of filter used. The study includes the comparison of low and high volume sampling techniques, as well as the distribution of blank and deposited lead values on the surface of the glass fiber filter used in the high volume sampling technique.
