This volume of the IARC Monographs provides evaluations of the carcinogenicity of isobutyl nitrite,β-picoline,   methyl acrylateEthyl acrylate2-ethylhexyl acrylate, and trimethylolpropane triacrylate

The four acrylates evaluated are chemicals with a high production volume that are produced worldwide. Methyl acrylate is used in the production of acrylic fibres and fire-retardant fabrics. Ethyl acrylate is one of the principal monomers used worldwide in the production of styrene-based polymers, which can be used for medical and dental items. Ethyl acrylate is also used in surface coatings for textiles, paper, leather, and food contact materials, and as a food flavouring agent. 2-Ethylhexyl acrylate is used as a plasticizing co-monomer in the production of resins for pressure-sensitive adhesives, latex paints, reactive diluent/cross-linking agents, textile and leather finishes, and coatings for paper. Trimethylolpropane triacrylate, available as a technical-grade product that also contains incomplete reaction products, is used primarily in production of ultraviolet-curable inks, paint additives, coatings, and adhesives.

β-Picoline, a methyl pyridine, is widely used as a starting material for pesticides (e.g. chlorpyrifos) and pharmaceuticals (e.g. vitamin B3). It is also used as a flavouring substance in foods and beverages. Isobutyl nitrite is used an intermediate in the syntheses of solvents and fuels, and exposures also occur through its use as a recreational drug.

Exposure to all six agents considered may occur in the general population as well as in various occupational settings.
