Identification and quantification of plasticizers, bisphenol
Diethyl phthalate was detected in three medicines: the highest concentration (17.03mgkg -1) was found in capsules. The other plasticizers and bisphenol A levels were below the limits of quantification in the all samples. All tested products were safe for use, except two clay-originated products.
Identification and quantification of plastic additives
To detect, identify and quantify MPs, several approaches have been developed, ranging from the simple visual inspection (by the naked eye or microscopically) to more advanced techniques such as...
Identification and quantification of bisphenol A and
For both plastics, samples are dissolved in tetrahydrofuran followed by a precipitation of the plastic by addition of ethanol. Results obtained point out residual bisphenol A amounts for polycarbonate samples ranging from 0.6 to 0.8% and for polyvinylchloride samples less or equal to 5 ppm. No bisphenol B was detected in the samples tested.
Identification and quantification of bisphenol A and
A gas chromatography with mass spectrometry method has already been developed and published for the identification and quantification of 14 phthalates and five nonphthalate plasticizers in polyvinylchloride medical devices.
- How many phthalates and nonphthalate plasticizers are in polyvinylchloride medical devices?
- A gas chromatography with mass spectrometry method has already been developed and published for the identification and quantification of 14 phthalates and five nonphthalate plasticizers in polyvinylchloride medical devices.
- Does salinity affect the concentration of plasticizers in the Bay of Bengal?
- Wetland: Although the concentration of total plasticizers decreased towards the Bay of Bengal, the percentage contribution of DEP and DnBP increased slightly which could be due to the influence of increasing salinity as observed elsewhere ( Paluselli et al., 2018 ).
- Are plastic additives a potential emerging organic pollutants (EOPS)?
- Plastic additives which are also potential emerging organic pollutants (EOPs) such as plasticizers and additives (bisphenol A (BPA) are used separately or together in products such as textiles, food containers, detergents, personal care products, insecticides, paints and above all in various types of polymers (Schmidt et al., 2019).
- Which dumpsite has the highest concentration of plasticizers?
- Among dumpsites, highest concentration of total plasticizers (442 ng/g), BPA (110 ng/g) and Cu (6212 mg/kg) were observed in Kodangaiyur located in the northern part of Chennai city (CN DS 02). Maximum DEHA level in this study was observed at this site (310 ng/g). Chennai is the capital hub for automobile industry in India ( Zhang et al., 2008 ).
- Are plasticizers and BPA a problem in estuarine waters?
- Similar to HRE, elevated levels of both plasticizers and BPA in estuarine waters when compared with other coastal waters have been associated with extensive shipping traffic at port/harbor sites in Cantrabrian Sea, Spain ( Sánchez-Avila et al., 2013 ).
- Are plasticizers a source of BPA in Hooghly River?
- Geo-mean concentrations of plasticizers were had 2–5 fold higher in riverine region than estuarine region. Plastic debris in tourist spots is a possible source of BPA in Hooghly River. Industrial sludge was identified as a point source for DEHP in Howrah district. Sediment can act as a sink for DEHP and secondary source for BPA, DEP and DnBP.
