Abstract/OtherAbstract:
This study investigated the occurrence of dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate (DiBP), di-n-butyl phthalate (DnBP), benzylbutyl phthalate (BBP), di(2- ethylhexyl) phthalate (DEHP), dicyclohexyl phthalate (DCHP) and di-n-octyl phthalate (DnOP) in raw cow's milk and feed from Belgian farms in order to determine their most relevant contamination pathways in milk. Measurable levels of DMP, DEP, DnBP, DCHP and DnOP were found in various feed samples, although they were not observed in milk. A plausible explanation for this is that they are rapidly metabolised in cows. DEHP and in a smaller degree also DiBP and BBP levels in milk seemed to vary across seasons and farms. DiBP and BBP levels were lower in summer than in winter milk, which was in contrast with what was observed for DEHP. This is possibly due to another feed composition during summer and winter. Comparing BBP and DEHP concentrations in manually with those in mechanically obtained milk revealed that, besides environmental contamination via feed ingestion, contact materials used during the mechanical milking process is another important contamination pathway. Concentrations observed in this study confirm the decreasing trend of DEHP in European cow's milk owing to the substitution of DEHP by other plasticisers.
