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...
