RESUMO
Our study has examined the valuation of exposure to dust, noise and hand-arm vibrations (HAVs) during "extra-professional" activities of do-it-yourself, like wood smoothing, considering a group of 8 heterogeneous volunteer subjects (not expert of the sector), to find any kind of variability among the subjects. The results have shown a moderate risk for dust exposure and a realer one for HAVs, also higher noise exposure levels when an aspiration system is added to the sander. It's important that the exposure time considered in this study is not comparable to professional time exposure, cause of the "domestic" feature of this activities. Moreover, data could be influenced by different use conditions, grip and material grounds. It's also significant that there are not controls, formation and information of the subjects about the health risks, as well as ipersusceptibility.

The Authors provide the data gathered from measurements of nitrous oxide in the operating room of Puglia during the period between 1993 and 2003. They prove significant reductions of pollution according with time and they verify lower pollution levels in the operating rooms of private hospitals with respect to public facilities. The importance of the maintenance of gas distribution and evacuation systems is shown and a method of environmental and biological monitoring is provided. Finally, the Authors prove the utility of the graphic representation of the measurements, conduced utilising dedicated instrumentation.
