HYDROGENATED TERPHENYL CONTAMINANTS IN RECYCLED PAPER

Cardboard packages, made from recycled material containing carbonless copy paper (CLCP), may produce food contamination by migration of some water-insoluble chemicals used as solvents in CLCP. The identificatio n and quantification of partially hydrogenated terphenyls (HTP) in mat rices as food, food packages and CLCP are reported. Results are discus sed in relation to the simultaneous presence in many samples of diisop ropylnaphthalene mixture (DIPN) and HTP.
