Plasticizers and bisphenol A: Emerging organic pollutants along the
Concentration of 7 plasticizers and bisphenol A in riverine and estuarine region along urban, suburban, rural, port and wetland transect from Hooghly River. In terms of concentration of the EOPs, RR was found to be significantly different ( p< 0.05) than ER.
Plasticizers and bisphenol A in Adyar and Cooum riverine
7plasticizers came from bis(2-ethylhexyl) phthalate (DEHP), in accordance with the high production and usage of this compound. BPA varied between 10.70–2026 and 7.58–1398 ng/g in ARS and CRS, respectively. Average concentrations of plasticizers and BPA were four times higher in electronic waste (e-waste) recy-
Identification and quantification of plasticizers, bisphenol, and
Di-methyladipate was also present in only one sample. 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.
Molecular Toxicity Mechanism of Plasticizers in the Reservoir
They are not permanently covalently bound to the plastics. Therefore, they can slowly diffuse into the reservoir environment and cause environmental pollution. Plasticizers are ubiquitous existence, and their metabolites were found in the air, soil, water, and biota [ 1, 2, 3 ]. Bisphenol A (BPA) and phthalates (PAEs) are the most essential
Baseline investigation on plasticizers, bisphenol A, polycyclic
Highest concentration of plasticizers (624 ng/g) and BaP (100 ng/g) in Chennai was found in a core e-waste recycling workshop at Pudupet (CN EWR 02). While most of the EWR sites showed elevated DEHP and BBP, DEHA was high in the shredding and dismantling sites located within the industrial corridor of northern Chennai possibly due to its usage as hydraulic fluid.
- What is a plastic stabilizer?
- Stabilizers are additives that mitigate the degradation of plastic products by protecting the polymer chain or avoiding the formation of peroxides. Common stabilizers include bisphenol A, benzophenones, triazoles, cadmium and lead compounds, nonylphenol compounds, and octylphenol (Hahladakis et al., 2018).
- Which plasticizers are not based on phthalates?
- Non-phthalates are commonly used as phthalate substitutes, and plasticizers not based on phthalates include trimellitic esters, phosphoric esters, benzoates, and adipates (Carmen, 2021). The latter are the most widely used non-phthalate plasticizers and are commonly used in the production of polyvinyl chloride.
- Can plastic additives be used in food and pharmaceuticals?
- Plastic products are used in large amounts in daily life, such as plastic packaging used in the food industry, the pharmaceutical industry, and the courier industry, which leads to the possibility of migration of plastic additives into food and pharmaceuticals (Luo et al., 2022).
- Can plasticisers migrate from plastic water bottles?
- This study investigates the potential migration of plasticisers, plastic components and additives from several plastic water bottles. Compounds studied were phthalates (dimethyl phthalate, di-n-butyl phthalate, benzylbutyl phthalate, bis (2-ethylhexyl) phthalate), bis (2-ethylhexyl) adipate, octylphen …
- 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 ).
- Which stabilizer is used in polyethylene & polyvinyl chloride?
- As one of the most widely produced stabilizers with an annual production of more than 8 million tons (Sharma et al., 2022), bisphenol A (BPA) is used as both a stabilizer and plasticizer in the production of polyethylene, polypropylene and polyvinyl chloride (Rani et al., 2015).
