Rome is vulnerable to chemical, biological, radiological, nuclear, and explosive (CBRNe) attacks. The study evaluates Rome's advanced emergency departments' state of emergency plans for massive influx of injures (PEIMAF) plans for CBRNe attacks. We propose a chemical attack on Saint Peter's Square during the Pope's General Assembly and its effects. The National Stockpile Antidotes' activation and territorial distribution timing work well for chemical attacks. We also estimated activation timing. Our data show that despite a good organization, travel times can be improved. We also believe that all major Roman hospitals must develop the PEIMAF, which should be followed by an organized training plan involving theoretical teaching and indoor and outdoor simulation to train hospital staff and evaluate PEIMAF weaknesses and vulnerabilities. The effectiveness and efficiency of first aid depend on timing, and each PEIMAF analyzed, while coherent and adequate for internal purposes, fails to integrate with the other hospitals. Integration can speed up National Stockpile Antidotes delivery and save lives. For the best CBRNe response, detailed intervention protocols must be created, updated daily, and exercised.

The air quality monitoring is based on the determination of some gaseous pollutants and PM10 and PM2.5. Recent studies have reported the importance of the determination aerosol fraction below 1 µm both for the dynamic of the airborne and for the public health issue. This paper would like to investigate the importance of this fraction in the air quality monitoring. Further, a particular focus will be devoted the role of the Ultrafine Particles, i.e. particles below 100 nm, in the aerosol formation and in the human exposure. Two case studies will be presented and discussed on how the submicron particles can be determined and interpreted their role. In the first case, the measurements will be performed in downtown Rieti, city located in central Italy, 100 km North from Rome, with the scope to draw the behavior in relationship to the emission flexes. In the second scenario, the personal exposure of pedestrians will be investigated in Venafro, a small city located 150 km South-East Rome, by means of measuring PMx, total submicron fraction, different aerosol dimensional sizes in the range 5-360 nm along with the total Volatile Compounds. The different sources and contributions affecting the aerosol levels in the two areas will be investigated and extensively discussed as well as the role of the such particles in the aerosols science.

The amount of outdoor particles that indoor environments receive depends on the particle infiltration factors (Fin), peculiar of each environment, and on the outdoor aerosol concentrations and size distributions. The respiratory doses received, while residing indoor, will change accordingly. This study aims to ascertain to what extent such doses are affected by the vertical distance from the traffic sources. Particle number size distributions have been simultaneously measured at street level and at about 20 m height in a street canyon in downtown Rome. The same Fin have been adopted to estimate indoor aerosol concentrations, due to the infiltration of outdoor particles and then the relevant daily respiratory doses. Aerosol concentrations at ground floor were more than double than at 20 m height and richer in ultrafine particles. Thus, although aerosol infiltration efficiency was on average higher at 20 m height than at ground floor, particles more abundantly infiltrated at ground level. On a daily basis, this involved a 2.5-fold higher dose at ground level than at 20 m height. At both levels, such doses were greater than those estimated over the period of activity of some indoor aerosol sources; therefore, they represent an important contribution to the total daily dose.
