Diisononyl 1,2-cyclohexanedicarboxylic acid (DINCH) and Di(2
Gas chromatography (GC) in connection with standard mass spectrometry (MS) is the favourite method to analyse plasticizers. Concerning volatility and molecular weight of the analytes the GC/MS method covers compounds ranging from short-chain phthalates like Dimethylphthalat (DMP) up to Di (2-ethylhexyl)phthalate (DEHP) ( Heise and Litz, 2004 ).
LC/MS method to determine plasticizers in indoor dust
Plasticizer, LC/MS method, Indoor dust INTRODUCTION Plasticizers are being used on a large scale worldwide (Bizzari et al, 2000). Their occurrence in indoor dust has been demonstrated, with a content of up to 12 g/kg (Phner et al, 1998; Butte et al, 2001). The concern about elevated indoor concentrations and toxicological
Occurrence of legacy and alternative plasticizers in indoor
In the present study, an analytical method has been developed for the quantification of plasticizers (7 legacy phthalate esters (LPEs) and 14 alternative plasticizers (APs)) in indoor floor dust based on ultrasonic and vortex extraction, Florisil fractionation and GC-(EI)-MS analysis. Dust samples (n = 54) were collected from homes, offices
Simultaneous determination of legacy and emerging
The aims of our study were (i) to develop and validate a method for the simultaneous quantification of the targeted analytes by LC-MS/MS, and (ii) to test its applicability to the analysis of PFRs and plasticizers in household dust ( n = 10) sampled in Guangzhou, China.

Identifying Citric Acid Esters, a Class of Phthalate
Zhang et al. (2025) found that ATEC, BTHC, trimethyl citrate (TMC), and trioctyl citrate (TOC) were present in indoor dust samples from different indoor microenvironments, such as electronic...
- Which method is used to analyze plasticizers?
- Gas chromatography (GC) in connection with standard mass spectrometry (MS) is the favourite method to analyse plasticizers. Concerning volatility and molecular weight of the analytes the GC/MS method covers compounds ranging from short-chain phthalates like Dimethylphthalat (DMP) up to Di (2-ethylhexyl)phthalate (DEHP) (Heise and Litz, 2004).
- Are microplastics present in dust?
- Microplastics (MPs) have been observed in dust in previous studies. However, the mass concentrations of dominant MPs in dust and the exposure risk to human remain unclear. In this study, indoor and outdoor dust samples were collected from 39 major cities of China.
- How many phosphorus flame retardants and plasticizers can be detected simultaneously?
- In the present study, an analytical method has been developed and validated for the simultaneous detection and quantification of 19 PFRs (14 legacy organophosphorus flame retardants (PFRs) and 5 emerging PFRs (ePFRs)) and 20 plasticizers (7 legacy plasticizers (LPs) and 13 alternative plasticizers (APs)).
- How to identify a polymer in dust?
- To chemically identify the polymer in dust, μ-FTIR (Thermo Scientific, Nicolet iN10, Madison, WI, USA) with a mercury cadmium telluride (MCT) detector was used in transmission mode. The samples were prepared and observed on the pressure pool including a diamond window.
- Are PET & PC microplastics common in dust?
- PET and PC microplastics (MPs) are widespread in dust. PET MPs ranged from 1550 to 120,000 mg/kg in indoor dust. μ-FTIR analysis indicated that polyester was an important type of MPs in dust. Positive correlation was found between fiber abundance and PET concentrations in dust. High daily intake of MPs through indoor dust was estimated.
- Are microplastics in dust a risk factor for human exposure?
- Dust is a fate of many contaminants and may be an important medium for the human exposure to these contaminants. Microplastics (MPs) have been observed in dust in previous studies. However, the mass concentrations of dominant MPs in dust and the exposure risk to human remain unclear.
