[Occupational hazards in management of an experimental constructed wetlands]. / Rischi professionali nella gestione di un impianto sperimentale di fitodepurazione.

The sewage from urban settlements is an important cause of water pollution. Recent Italian legislation offers new possibilities for intervention in the purification of wastewater. The "Decreto Legislativo" 152 of April 3, 2006, indicating "Environmental Standards", recommends the possible use of constructed wetlands considered particularly suitable for small and medium communities according to low operating costs, lack of energy, and manageability. The Authors, after describing the characteristics of these facility, analyze the occupational risks associated with the control and maintenance of a experimental subsurface constructed wetland (H-SSF, SubSurface Horizontal Flow) coming to the conclusion that the management of this type of facility has a low risk of exposure to biological agents.
