Abstract

A short study of the SO2, NOx, CO2 influence on cultural heritage, as in the case of Sf. Michael’s Church Masonry in Cluj-Napoca, Romania is presented; special attention is given to the black crust formation. The composition of the black crust was determined; the black crust was then cleaned with the laser-based chemical method and with the physical method of cellulose plaster soaked in ammonium hydrogen carbonates [NH4 (HCO3)].

Key Words   
Air pollution, SO2, NOx, CO2, Black crust, St. Michael’s Church, Cluj-Napoca, Romania
