The regulatory limits are those of Italian Legislative Decree 133/2005. For particulates, hydrochloric acid, nitrogen oxides, sulphur oxides, carbon monoxide, hydrofluoric acid, and total organic carbon, the values are the average continuously measured values and the limits are those for daily averages. For all other components, the values are the average of periodic measurements and the limits are for each individual measurement. In the new lines at Ferrara, Forlì, Rimini and Modena, mercury levels are continuously measured.
