Hulst, A.G. (author), Verstappen, D.R.W. (author), van der Riet-van Oeveren, D. (author), Vermeulen, N.P.E. (author), Noort, D. (author)In the current paper we show that exposure of human callus to isocyanates leads to covalent modifications within keratin proteins. Mass spectrometric analyses of pronase digests of keratin isolated from exposed callus show that both mono- and di-adducts (for di-isocyanates) are predominantly formed on the ε-amino group of lysine. In addition,...article 2015

(author), TNO Kwaliteit van Leven (author)An adapted method for the quantitative determination of isocyanates in air was implemented and validated in-house. The method was based on air sampling using an impinger flask containing di-n-butylamine (DBA) in toluene and a glass fibre filter in series. The DBA derivatives were determined using liquid chromatography and tandem mass...article 2008
