Applicazione e Monitoraggio di miscele biocide per pulitura di superfici attaccate da patina biologica

Abstract

Abstract: The aim of the present study is to identify and characterise the best biocidal formulation for controlling biodeterioration phenomena. Given the requirements which define a good biocide, i.e. being environmentally sustainable, negligible interference with stone materials, being safe from a toxicological point of view, being easy to apply, having long-lasting effect, and being cost effective, the overall objective is to minimise environmental impact by ensuring an efficient use of resources. The attainments of our approach have been:protection of operators' and end users' health, sustainability, reversibility, compatibility and minimal intervention criterion. The specific objectives of this work are articulated in 4 points: 1. Recording of metabolic activity of the active patinas present upon the artefact surface, grown in spontaneous environmental conditions 2. Registration of the data on effectiveness of commercial biocidal mixtures, applied to real case studies, by Bioluminescence analyses 3. Create a connection system to collect all the recorded data in order to compare mixtures applied on different materials with objective values. 4. Monitoring over time of the mixtures applied, aiming to recording biocidal efficiency andpossible chromatic alterations.
