Beyond DEHP: high-molecular-weight phthalateand non-phthalate plasticizers in German rivers
Regine Nagorka and Jan Koschorreck, German Environment Agency
Results
• In 2014, total levels for plasticizers ranged between 0,5 -11 µg/g dw SPM
• At some sites the levels of plastizisers were higher in 2014 than in
2005/06.
• DEHP levels decreased by 20 to 70% from 2005 to 2014 and the high-
molecular-weight phthalate DINP became the dominant plasticizer.
• Concentrations for the DEHP-substitute DPHP (EU CoRAP list, evaluation
2019) increased at all sites.
• The new non-phthalate plasticizer DINCH – marketed in the EU since
2002 - is present in SPM samples from all sites.
OutlookAs a next step we will elaborate temporal trend series with additional ESB
samples.

Objective The global demand for plasticizers is expected to rise to 10 million tons per year by 2020. High-molecular-weight phthalates and non-phthalates are replacing the former
blockbuster DEHP on the market. Some of the substitutes are under scrutiny, e.g. DPHP that has been added to the EU REACH CoRAP list. Data are needed on the spatial
and temporal trends of these substances in the environment.
MethodsSuspended particulate matter (SPM) was collected monthly at 16 sampling sites from major rivers in Germany. SPM was sieved to < 2mm and stored above LN2 in the German Environmental Specimen Bank (ESB). Sample treatment involved solvent extraction (ultra sonic) and Florisil Clean-up. Samples were analysed with APCI-LC-MS/MS.
