||Modern manufacturing practices, especially in the automotive industry, often involve resistance welding through adhesives and sealants. During welding, fumes that are possibly harmful to health may be inhaled by workers. Little is known about the concentration or composition of the fumes emitted, making it difficult to assess the risks to health arising from welding activities. In this study, fume composition data were generated for resistance welding through a representative range of epoxy-based adhesives and polybutadiene-based sealants for the purpose of enabling a comprehensive risk assessment. Benzene, 1,3-butadiene and acrylonitrile were the most harmful compounds identified. However, concentrations were low. Concentrations of carcinogenic polyaromatic hydrocarbons were also low, less than 1µg/m3.
