Emission load of car service interiors

Abstract

Car service centres are specific in terms of production of pollutants. The aim of the paper is to assess the quality of indoor environment of car service interiors with respect to the safe range of oxocarbon emission limits, concentration of gaseous and solid aerosols of selected chemical pollutants and occupational noise exposure. Measurements of concentration and exposure time indicated that the permitted limits were kept. CO concentration reached values in the range from 0 to 10 ppm, CO2 concentration was observed in the range from 493 to 967 ppm. Concentration of solid aerosol of polyester bitumen reached the maximum value of 0.37 mg/m3, while for gaseous aerosol (e.g. toluene) it equalled 8.114 mg/m3. Measurements of chemical factors were carried out and evaluated by companies with appropriate accreditation. Occupational Exposure Limits (OELs) were higher in case of all selected substances. OEL was not demonstrably exceeded at any chemical factor. Noise emissions approached the limit values; therefore, hearing protection is required.
