Baseline investigation on plasticizers, bisphenol A
Baseline investigation on plasticizers, bisphenol A, polycyclic aromatic hydrocarbons and heavy metals in the surface soil of the informal electronic waste recycling workshops and nearby open dumpsites in Indian metropolitan cities Environ Pollut. 2025 May;248:1036-1045. doi: 10.1016/j.envpol.2018.11.010.

Baseline investigation on plasticizers, bisphenol A
The method detection limit (MDL) ranged between 0.09 and 0.24 ng/g for plasticizers, 0.07–0.61 ng/g for PAHs and 0.06 ng/g for BPA. With each set of five samples, one spiked procedural and solvent blank were run to check for background contamination, peak identification and quantification.
Baseline investigation on plasticizers, bisphenol A
In Indian cities the end product of various e-waste activities are dumped in the dumpsites along with domestic waste. MSW contains 15% by volume of various polymeric materials. Certain soil parameters (pH, moisture) might aid the release of relatively high amount of toxicants called plasticizers with toxicological potential (Vieceli et al., 2011).
Quantification of Plasticizers in Poly(vinyl chloride
Quantification of Plasticizers for the determination of DMP, DEP, DBP, and DEHP in packag-ing foils on silica gel plates [19]. Therefore, the aim of the present study was to apply high-per-formance thin-layer chromatography (HPTLC) for a rapid and cost-effective determination of different types of plasticizers in different PVC materials.

- Should bio-based plasticizers be valorized in industrial processes?
- Valorization of bio-based plasticizers in several industrial processes is presented. The current industrial revolution emphasized the necessity to use environmentally friendlier sources and strategies to meet the bio-based economy challenges of the modern world.
- What factors influence the design of efficient plasticizers?
- Numerous parameters such as solubility, polarity, and structural compatibility are considered important and can influence the designing of efficient plasticizers. In this context, a plethora of research has given their structural attributes along with their compatibility with different elastomers and plastics.
- Should petroleum-based plasticizers be replaced with bioplasticizers?
- The substitution of petroleum-based plasticizers with bioplasticizers offers noteworthy advantages, such as recyclability, biodegradability, high lubricant power, low diffusion coefficients in the polymeric matrix and very low volatility.
- What are bio-based plasticizers based on epoxidized oils?
- Bio-based plasticizers based on epoxidized oils from different sources such as cottonseed oil, coconut oil, sunflower oil, castor oil, linseed oil and soybean oil have been reported as environmental plasticizer (Bouchoul et al., 2014; Ferri et al., 2017; Jia et al., 2017; Fu et al., 2019; Cheng et al., 2019; Gama et al., 2019; Ye et al., 2019).
- How to predict plasticizer/polymer compatibility?
- Plasticizers, which are involved in secondary interactions with the polymer matrix, developed various extents of compatibility with it. One of the recommended methods to predict the plasticizer/polymer compatibility was based on their chemical structures and functionalities such as ester, epoxide, aromatic groups, etc.
- Why are plasticizers called processing additives?
- Plasticizers are also named as processing additives because they have a deep influence on the processing of the polymer by improving filler dispersion, reducing the elastic modulus, lower power demand and better flow properties.
