In particular, two important archeological places in the old part of the city of Salerno, Italy, were analyzed Fruscione Palace and S. Pietro a Corte. The work focused on the influence of tourists on environmental pollution correlated to indoor air quality during some social and cultural events. Moreover, we focused on the possible use of the carbon isotopic composition of CO2 as a tool for environmental studies in the field of cultural heritage. The results showed a good relationship between the isotopic composition of CO2 and the variation of pollutants concentration in the air, demonstrating that it is a valid tool and non-invasive marker to monitor environmental pollution of museums and cultural heritage sites.In this study, Mg-modified sludge biochar (MB) and Mg-Fe double oxides/sludge biochar composites (MFB) were synthesized for enhanced removal of phosphate from aqueous solution. The phosphate adsorption followed the Langmuir-Freundlich isotherm model, and the maximum capacity was 142.31 mg P/g and 35.41 mg P/g for MB and MFB, respectively. MB exhibited the higher adsorption capacity at pH 8-9 and performed well under the influences of coexisting anions and temperature (4-45 °C). Adsorption kinetics was well described by the pseudo-second-order kinetic model, indicating the chemical bonding between phosphate and adsorption sites. The adsorption capacity of phosphate decreased by less then 15% after three successive recycles. Based on FTIR, XRD, and XPS analysis, the main mechanisms for phosphate removal by MB included electrostatic attraction, surface complexation, and precipitation. Hydroxides/oxides particles of Mg on the surface of MB with positive charge coul
