  • Which plasticizer has the highest DEHP concentration in Rehlingen/Saar?
  • By 2017, the DEHP concentration in Rehlingen had dropped to 2080 ng/g dw. Currently, Diisononyl phthalate (DINP) is the plasticizer with the highest levels in the SPM samples (maximum value 4150 ng/g dw in Rehlingen/Saar).
  • What percentage of plasticizer load is derived from DEHP?
  • In the early samples from the Elbe, DEHP contributed with 50–59% of the total plasticizer load. The share of DEHP was comparatively lower in SPM samples from Rhine and Saar (34–45%), where instead the shares of DINP and DIDP increased. By 2017, the profile patterns had changed significantly and at the same time aligned between the river basins.
  • Can DEHP be substituted for plasticizers in freshwater environments?
  • In contrast to the indoor environment, the substitution of DEHP in freshwater environments is accompanied by a noticeable shift towards potentially critical plasticizers. The percentage of plasticizers classified as a potential concern in the investigated riverine systems is now 16%, compared to only 2% in house dust.
  • How effective are LMW plasticizers in reducing phthalates in the EU?
  • As a result, the total EU market share of DEHP and other LMW phthalates in 2017 had dropped to 11% ( ). However, the effectiveness of the restriction of LMW plasticizers is only partially reflected in our findings: in 2017, the average DEHP content in SPM samples was still 24%.
  • Which phthalates dominate the plasticizer market?
  • Chemical management varies considerably between regions and on a global scale. DEHP still dominates the plasticizer market . Therefore, target analytes were often restricted to DEHP and other LMW phthalates. House dust samples in China, for example, were strongly dominated by DEHP and DBP .
  • Which phthalate is the dominant plasticizer in house dust?
  • HMW phthalates increased from 19% of the ∑plasticizer concentration to 46% between the mid-2000s and the late 2010s in house dust, and from 50% to 63% in SPM samples. Diisononyl phthalate (DINP) replaced DEHP as the dominant plasticizer in both compartments.
