poly(vinyl chloride) (pvc) is one of the most widely used plastics. however, a major challenge in recycling pvc is that there is no economical method to separate and remove its toxic phthalate plasticizers. this research made a breakthrough by extracting pvc with liquefied dimethyl ether (dme) and s.

recent attempts in the design of efficient pvc plasticizers,traditionally, the most common pvc plasticizers are phthalates. unfortunately, in the last few years, serious environmental protection and society health hazard issues have been raised, mainly because phthalate plasticizers have been found in soils, sea water and sediments, in leaving organisms and even in human breast milk [3,4,5,6,7]. under.

phthalates are a family of reprotoxicant compounds, predominantly used as a plasticizer to improve the flexibility and longevity of consumable plastic goods. after their use these plastic products find their way to the waste disposal sites where they leach out the hazardous phthalates present within them, into the surrounding environment, contaminating soil, groundwater resources, and the.

paes accumulate in aquatic environments worldwide and pose significant threats to organisms [9]. staple et al. (1997) [10]reviewed the literature on the acute and chronic aquatic toxicity of 18 phthalate esters, revealing that six esters, dimethyl phthalate (dmp), diethyl phthalate (dep), diallyl phthalate (dap), dibutyl phthalate (dbp), diisobutyl phthalate (dibp), and benzyl butyl phthalate.
impacts of phthalate plasticisers an emerging,researchgate,flexibility and durability of plastic products including polyvinyl chloride (pvc). based on the molecular weight, phthalates are grouped into low and high phthalates that shows diverse
- What are the most commonly used plasticizers in the world?
- Phthalates as the most commonly used plasticizers in the world are widely used in hundreds of products such as flexible polyvinyl chloride (PVC) products, perfumes, hair sprays, adhesives and glues, floor and wall coverings, cable jacketing, automotive products, toys, medical tubing and blood storage bags, food packaging materials, etc.
- Which phthalates have the most health and environmental concerns?
- Analytical methods The six phthalates with the most health and environmental concerns, including DEHP, BBP, DBP, diethyl phthalate (DEP), dimethyl phthalate (DMP), and DNOP were selected to be monitored in drinking water and water resources.
- Who is Pak & Pishro Chemical Company?
- Pak and Pishro Chemical Company is one of the main producer of stearates, PVC stabilizers & polymer additives in Iran. Our goal is to provide high quality products with the most competitive price.
- What is the contribution of DMP and DEHP to total phthalate levels?
- In general, DMP and DEHP exhibited high shares in the total phthalate levels for all the water sources, so that the sum of DMP and DEHP contributions to the total phthalate levels in the water distribution system, bottled water, surface water resources, and ground water resources were determined to be 69, 64, 74, and 68%, respectively.
- What are the ecological and human health effects of phthalates?
- The ecological and human health effects of phthalates are mainly related to interference with the endocrine systems of living beings. As endocrine disturbers (EDs), most of phthalates can cause adverse developmental, metabolic, neurological, immune, and reproductive effects.
- What are the CDIs and HQs of phthalates?
- The CDIs and HQs of the phthalates were consistent with the results of Domínguez-Morueco et al. (2014) reporting that the highest total CDIs of the phthalates via drinking water in adults and children were 9.09 × 10 −5 and 2.60 × 10 −5 mg/kg·d, respectively, and all the HQs of the phthalates were much lower one.
