Legacy and Emerging Plasticizers and Stabilizers in PVC Floorings: Impacts of an Industrial Transition and Recycling
AI summary Read the abstract
Researchers tested 151 new PVC floor products on the Swiss market and found that 16% still contained regulated toxic chemicals — mostly lead and the plasticizer DEHP — likely introduced through the use of recycled PVC content. The findings reveal that poorly regulated recycling can actually perpetuate hazardous chemical exposure in homes, undermining the safety goals of circular economy efforts.
Hazardous chemicals in building and construction plastics can lead to significant indoor exposure, health risks, and contamination of recycled materials. We systematically sample new PVC floor-ings on the Swiss market (n=151). We conduct elemental analysis using XRF, targeted and sus-pect GC MS analysis of ortho phthalates and alternative plasticizers, and bioassay tests for cyto-toxicity, oxidative stress, and endocrine, mutagenic, and genotoxic activities (for selected sam-ples). Surprisingly, 16% of the samples contain regulated chemicals above 0.1 weight%, mainly lead and bis(2-ethylhexyl) phthalate (DEHP). Their presence is likely linked with the use of recy-cled PVC in new floorings, highlighting that uncontrolled recycling can delay the phase-out of hazardous chemicals. Furthermore, 29% of the samples contain ortho-phthalates besides DEHP (mainly diisononyl and diisodecyl phthalates, DiNP and DiDP) above 0.1 weight%, and 17% of the 85 tested samples cause certain adverse biological effects. Together, they make up an addi-tional 35% of samples of potential concern. Moreover, both suspect screening and bioassay results indicate the presence of additional (potentially) hazardous substances, including emerging alterna-tive plasticizers. Overall, our study highlights the urgent need for accelerating the phase-out of hazardous substances and enhancing transparency of chemical compositions in plastics to protect human and ecosystem health and enable the transition to a safe and sustainable circular economy.

Legacy and Emerging Plasticizers and Stabilizers in PVC Floorings: Impacts of an Industrial Transition and Recycling
AI summary Read the abstract
This study systematically analysed 151 new PVC floor coverings on the Swiss market, finding that 16% still contained regulated hazardous chemicals — mainly lead and DEHP — above legal thresholds, likely introduced via recycled PVC. A further 29% contained alternative plasticizers not yet subject to the same scrutiny but detected in bioassays for cytotoxicity and endocrine disruption. The findings reveal that recycling of PVC can inadvertently reintroduce banned chemicals into new products, posing indoor exposure and health risks, and that some replacement plasticizers may themselves warrant toxicological concern.
Legacy and Emerging Plasticizers and Stabilizers in PVC Floorings and Implications for Recycling
AI summary Read the abstract
Researchers tested 151 new PVC floor products sold in Switzerland and found that 16% contained hazardous chemicals above regulatory limits, including lead and a banned plasticizer called DEHP. The likely source was recycled PVC mixed into new products, showing how recycling without proper quality control can keep toxic chemicals circulating. These floor materials can release harmful additives into indoor air, creating ongoing exposure risks for people living and working in these spaces.
Legacy additives in a circular economy of plastics: Current dilemma, policy analysis, and emerging countermeasures
AI summary Read the abstract
This review examines the problem of 'legacy additives' in plastic waste — formerly used substances such as certain flame retardants, stabilizers, and plasticizers now classified as substances of very high concern or persistent organic pollutants — and analyzes the policy and practical challenges they pose for circular economy recycling and reuse systems. The authors evaluate emerging countermeasures to prevent legacy additive contamination from re-entering product supply chains.
Legacy additives in a circular economy of plastics: Current dilemma, policy analysis, and emerging countermeasures
AI summary Read the abstract
This review analyzed the challenges posed by legacy chemical additives such as flame retardants and plasticizers in achieving a circular economy for plastics. Researchers found that recycling plastics containing these now-restricted or banned substances creates a dilemma, as hazardous additives can be reintroduced into new products, and the study discussed emerging countermeasures to address this problem.
Lead in plastics – Recycling of legacy material and appropriateness of current regulations
AI summary Read the abstract
Researchers measured lead (Pb) concentrations in a wide range of consumer and environmental plastics using X-ray fluorescence, finding that historical products like old toys and construction plastics still contain dangerously high lead levels that can spread into newer products when recycled. The findings show that plastic recycling can unintentionally redistribute toxic heavy metals into everyday consumer goods.
