Appartenente ad una nobile famiglia fiorentina, l'architetto Francesco Mazzeo Mazzei si formò e lavorò nel fervente clima culturale fiorentino di primo Ottocento. Dopo un apprendistato nel territorio volterrano, sotto la guida di Alessandro Manetti, Mazzei tornò a Firenze ed esercitò la sua professione soprattutto come restauratore. In particolare il restauro del Bargello divenne il modello a cui ispirarsi non soltanto in Toscana, ma anche in altre regioni italiane. Partecipe della vita politica, sociale e culturale di Firenze, Mazzei fu una figura chiave nella trasformazione della città in sede della capitale. ; Born in a noble family, the architect Francesco Mazzeo Mazzei grew up and worked in the Florentine lively cultural circle at the beginning of the 19th century. After having had some experience in Volterra, under the guidance of Alessandro Manetti, Mazzei came back to Florence and worked especially as restorer of historic buildings. In particular, the restoration of the Bargello became the model to reproduce not only in Tuscany, but also in other Italian regions. He took part in the political, social and cultural life of Florence and was one of the key figure in the transformation of the city into a capital.

AbstractDrinking water quality can be compromised at different stages, from raw water to treated one. This research aimed to evaluate the toxicity and genotoxicity of groundwater contaminated by fluorinated compounds treated in a drinking water treatment plant, through several bioassays. Water samples underwent chemical analyses and were assayed on Daphnia magna, Pseudokirchneriella subcapitata, Allium cepa, human leukocytes and Salmonella typhimurium. Physical–chemical parameters were always within the Italian legislation limits. Water after filtration and disinfection caused slight toxicity in D. magna; the sample after filtration inhibited the proliferation of P. subcapitata. None of the water samples exerted toxicity in A. cepa. All the analysed samples had genotoxic effects on A. cepa and human leucocytes, while only disinfected water caused mutations in S. typhimurium. A battery composed of tests on D. magna, P. subcapitata, S. typhimurium and A. cepa could represent a useful tool to verify the toxicity/genotoxicity through the water treatment stages and to improve drinking water quality management.
