It offers me a lot excitement to introduce this paintings of Prof. Dr. Ing. Fumagalli, a piece that covers either the advance and current cutting-edge of structural version recommendations. in my opinion, during this context, just a lack of expertise of the probabilities provided through experiments on types and infrequently an unjustified suspicion of them have during the past limited the advance that those equipment deserve.

2011a, b; Barro et al. 2009). Pegas et al. (2011a) measured indoor and outdoor concentrations of formaldehyde and other carbonyls at 14 elementary schools in Lisbon, Portugal. In all environments, indoor aldehyde levels were higher than those observed outdoors, particularly for formaldehyde. In another study (Pegas et al. 2011b), conducted in the same schools, the indoor and outdoor levels of carbonyls were evaluated during spring, autumn and winter. Most of the assessed carbonyls occurred at I/O ratios above unity in all seasons, thus showing the importance of indoor sources and building conditions in indoor air quality.

Mi et al. (2006) investigated 10 naturally ventilated schools in Shanghai finding that mean weekly indoor O3 level was 1–9 μg/m3 in spite of 17–28 μg/m3 outdoors. Gold et al. (1996) conducted a comparison of outdoor and classroom ozone exposures for school children in Mexico City, evaluating the effect of three distinct classroom conditions: (a) windows/doors open, air cleaner off; (b) windows/doors closed, air cleaner off; (c) windows/doors closed, air cleaner on. They found that, when outdoor O3 concentrations increased, indoor concentrations increased more rapidly when windows/doors were open.
