Species and characteristics of volatile organic compounds emitted from an auto-repair painting workshop

Abstract

Volatile organic compounds (VOCs) are secondary pollutant precursors having adverse impacts on the environment and human health. Although VOC emissions, their sources, and impacts have been investigated, the focus has been on large-scale industrial sources or indoor environments; studies on relatively small-scale enterprises (e.g., auto-repair workshops) are lacking. Here, we performed field VOC measurements for an auto-repair painting facility in Korea and analyzed the characteristics of VOCs emitted from the main painting workshop (top coat). The total VOC concentration was 5069–8058 ppb, and 24–35 species were detected. The VOCs were mainly identified as butyl acetate, toluene, ethylbenzene, and xylene compounds. VOC characteristics differed depending on the paint type. Butyl acetate had the highest concentration in both water- and oil-based paints; however, its concentration and proportion were higher in the former (3256 ppb, 65.5%) than in the latter (2449 ppb, 31.1%). Comparing VOC concentration before and after passing through adsorption systems, concentrations of most VOCs were lower at the outlets than the inlets of the adsorption systems, but were found to be high at the outlets in some workshops. These results provide a theoretical basis for developing effective VOC control systems and managing VOC emissions from auto-repair painting workshops.

A Decomposition-Based Multi-Objective Evolutionary Algorithm for Solving Low-Carbon Scheduling of Ship Segment Painting

“…Ship painting is a crucial process in ship construction and is also the most important source of pollution, emitting volatile organic compounds (VOCs), which not only harm the environment but also affect human health. According to statistics, the manufacturing industry accounts for about half of the global energy use and 38% of the global carbon dioxide emissions, while VOC pollution control will cause the rise of energy consumption of equipment operation, which is one of the important sources of carbon emissions in the ship manufacturing industry [3,4]. Therefore, reducing carbon emissions from ship painting has become a top priority.…”

High-solution emission patterns and health risks of volatile organic compounds from automobile repair industries in Beijing

“…Hence, the daily inhalation EC was collected in this study. During coating operation, the average daily inhalation EC of VOCs in each workshops ranged from 11.24 to 1460.70 μg•m -3 (Fig 3), which was higher compared with surrounding environments(Song and Chun 2021). The average daily ECi and EC of operators showed a similar pattern in solvent spraying workshops.…”

“…[64] The most commonly encountered VOCs in smoke are benzene, isoprene, xylene, and toluene. [65][66][67] The VOCs may irritate the eyes, watering, nose, and throat irritation, nausea/vomiting, asthma headache, and dizziness. [68] The continuous presence of human beings in an environment having VOCs for a prolonged period may cause cancer, especially lung cancer, liver and kidney damage, and central nervous system-related problems.…”
