This paper refers on the result of an experimental work developed in a quarrying site aimed to test the reliability of geostatistical approach as an alternative tool in the assessment of spatial variability of professional hazards. The case study is referred to the exposure of workers to airborne dust generated from typical quarrying activities. In such a risk assessment procedure in fact, the most useful alternative method to personal sampling is represented by defining the space-time variability of the physical agent. This step is, nevertheless, complex requiring a considerable amount of field surveys for carrying out the spatial distribution itself. This study falls into this context, with the intention of providing a methodological contribution in the phase of hazard characterization. So, after a systematic sampling campaign aimed to collect significant values of respirable dust concentration all around the site, the geostatistical method of Kriging is then proposed as an alternative tool to estimate dust concentration in the selected domain. The analysis is then completed comparing the estimated values with data sampled by means of ?leave one out? cross validation method.
