An integrated procedure for determining heavy metals concentrations in air particulate and in biomonitors

摘要

The aim of study is to assess a calibration procedure for utilising some vegetal species as biomonitors in an integrated monitoring network. We compare heavy metals concentrations in the atmospheric particulate collected on filters with the ones on vegetal samples. The sampling and the mass measurement of the atmospheric particulate are performed by means of a low volume #beta# -gauging sampler. For heavy metals biological monitoring, we have chosen two ryegrass species and we have developed a standardised culture cycle in which cultivation pots containing Lolium italicum and Festuca arundinacea are prepared. For evaluating heavy metals concentration we have utilised AAS techniques. Here we discuss the data collected in the first field survey (1997).
