VARIATION OF VOLATILE ORGANIC COMPOUND CONCENTRATIONS EMISSION IN THE ATMOSPHERE CORRELATED WITH TECHNOLOGICAL OPERATIONS AT THE PAINTING OPERATION
Abstract
Following the vehicle painting process, residual gases containing volatile organic compounds (VOCs) are released into the atmosphere through exhaust pipes. Entrepreneurs are legally obliged to report to the Environmental Protection Agency, which, in turn, reports to the European Union to reduce greenhouse gas emissions and achieve climate neutrality by 2050. The current paper investigates the temporal variation of VOC concentrations correlated with technological processes carried out in vehicle painting shops. Three sets of one-hour measurements were taken for each technological operation (sample preparation, painting, sample drying). Currently, atmospheric emission monitoring from paint shops is conducted only under maximum operating conditions of the painting installation, with a measurement period of at least half an hour. In this case, the reported results indicate higher emission values for a day or a calendar year. The objective of the paper is to measure VOC concentrations from a vehicle paint shop and correlate which painting processes release the highest amounts of VOCs into the atmosphere, aiming to identify possible measures to reduce environmental pollution. Research results indicate that the highest recorded concentrations occur during the painting operation, followed by the drying of parts and then the cleaning of parts through degreasing.
