Phthalates and non-phthalate plasticizers in sediment
Due to regulations on phthalates, non-phthalate plasticizers (NPPs) are now used as an alternative. Limited studies have been conducted on the occurrence and distribution of NPPs. In this study, sediment samples were collected from 50 locations along the Korean coast to assess the occurrence, distribution, sources, and ecological risks of
Diverging trends of plasticizers (phthalates and non
This was accompanied by their substitution with high molecular weight (HMW) phthalates and non-phthalates. 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.
Highly efficient non-phthalate plasticizer for many different
DOA (Dioctyl Adipate) is a non-phthalate, highly efficient plasticizer designed to give excellent low temperature properties to polyvinyl chloride (PVC). Its excellent wetting characteristics make it desirable for plastisol use where low plasticizer content coupled with low viscosity, as well as good fusion characteristics are necessary. DOA is
Research progress of novel bio-based plasticizers and their
Abstract Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing. Owing to the negative impact of petroleum-based plasticizers on human health
Alternative Plasticizers As Emerging Global Environmental and
Plasticizers are synthetic chemicals that are commonly used in polyvinyl chloride (PVC) based products, food packaging, children’s toys, medical devices, and adhesives. There are about 30 000 chemicals can potentially be utilized as plasticizers.
- Are there phthalates and non-phthalate plasticizers in the coastal environment of Korea?
- Conclusions This is the first nation-wide survey of phthalates and non-phthalate plasticizers in the coastal environment of Korea. Phthalates and alternative plasticizers were detected in all sediment samples from the coastal zone of Korea. DEHP and DEHT were the dominant phthalates and NPPs, respectively.
- Are phthalates and non-phthalate plasticizers found in coastal sediment?
- Korea is the world's largest consumer of plastic, with increasing production and consumption ( European Plastics and Rubber Machinery, 2016 ). The present study assesses the occurrence, spatial distribution, and potential contamination sources of phthalates and non-phthalate plasticizers in coastal sediment from Korean coastal waters.
- Do phthalates and non-phthalate plasticizers pose ecological risk to benthic organisms?
- Given the occurrence of phthalates and non-phthalate plasticizers, including DEHP, further studies are required to identify the contamination sources and assess the ecological risk to benthic organisms posed by these contaminants in coastal environments. Fig. 5 Cumulative distribution (%) of DEHP concentrations measured in sediments from.
- What is plasticizer phthalate based?
- Plasticizer is a chemical substance capable of making plastics softer, and phthalate is one of the most common materials to achieve it. However, phthalate-based plasticizer has often been blamed for disrupting the hormone system and thus been restricted from toys and furniture.
- Are phthalate plasticizers contaminating the environment?
- DEHA and DEHT were detected in almost all sediment samples (detection rate: 98%), also suggesting major contamination by non-phthalate plasticizers. The occurrence of phthalates in the environment is related to production and consumption in industrial markets ( Gao and Wen, 2016 ).
- How are phthalates and NPPs distributed along Korea's Coast?
- The spatial distribution of phthalates and NPPs along Korea's coast is governed by harbor-zone activities and sedimentary organic carbon. Significant correlations were observed among the compounds of phthalates and NPPs in sediments, suggesting similar sources and environmental behavior in coastal environments.
