Migration of plasticizersphthalates, bisphenol A and alkylphenols from plastic containers and evaluation of risk

Food Additives & Contaminants Part A, Journal Year: 2011, Volume and Issue: 28(5), P. 676 - 685

Published: March 13, 2011

This study investigates the potential migration of plasticisers, plastic components and additives from several water bottles. Compounds studied were phthalates (dimethyl phthalate, di-n-butyl benzylbutyl bis(2-ethylhexyl) phthalate), adipate, octylphenol, 4-nonylphenol bisphenol A. Polycarbonate (PC), high-density polyethylene (HDPE), low-density (LDPE), terephthalate (PET) polystyrene (PS) plastics used in bottling sector tested using three kinds total or specific tests: (1) standard method UNE-EN ISO 177; (2) ultrasonic forced extraction; (3) 13130-1. In addition, bottled waters contained different materials analysed to determine target compounds real conditions. all cases, samples solid-phase extracted Oasis HLB 200 mg cartridges GC-MS scan-acquisition mode. Bisphenol A detected incubated samples, indicating that food can occur at experimental conditions tested. The daily intake was calculated according levels assessment consumers' risk evaluated taking into consideration toxicological legislative values.

Occurrence and sources of selected phenolic endocrine disruptors in Ria de Aveiro, Portugal

Environmental Science and Pollution Research, Journal Year: 2009, Volume and Issue: 17(4), P. 834 - 843

Published: Dec. 16, 2009

Ria de Aveiro (Portugal) is a shallow coastal lagoon of high economic and ecological importance. Hardly any data on its chemical pollution by polar organic pollutants are available in literature. This study focused the presence sources series phenolic endocrine-disrupting compounds (EDCs) this area, including parabens, alkylphenolic bisphenol-A (BPA). A number possible present large harbours lagoon, city rivers discharging into area. recently constructed submarine wastewater outfall, located few kilometres from inlet has also been suggested as source to several publications. The aim current field was investigate occurrence main endocrine disruptors Aveiro. An extensive sampling campaign performed, with surface water grab samples taken at over 50 locations, duplicate different days. Samples were treated using solid phase extraction analysed liquid chromatography tandem mass spectrometry. Concentrations generally low: not exceeding 20 ng/L for most analytes. Levels river exceeded those factor 3 500 (o-phenylphenol (PhP) nonylphenoxy ethoxy acetic acids (A9PEC), respectively), concentrations up 700 BPA 7,300 A9PEC. showed EDC levels similar rest but Aveiro, elevated observed alkylphenol ethoxylates (A9PEO), A9PEC, PhP BPA. Wastewater effluents low whilst reached micrograms per litre. discharged ocean via marine near outfall slightly only A9PEO, it does seem be significant these EDCs All studied detected found some itself. all investigated Caster Antuã which discharge lagoon. identified secondary source. As tidal exchange volume much larger than freshwater input rivers, remained

Applications of Nonconventional Green Extraction Technologies in Process Industries: Challenges, Limitations and Perspectives

Sustainability, Journal Year: 2020, Volume and Issue: 12(13), P. 5244 - 5244

Published: June 28, 2020

This study reviewed five different nonconventional technologies which are aligned with green concepts of product recovery from raw materials on industrial scale, minimal energy consumption and chemical use. Namely, this supercritical fluid extraction (SCFE), pressurized liquid (PLE), microwave-assisted (MAE), ultrasound (UAE) pulsed electric fields (PEFE). paper provides an overview relevant innovative work done in process industries plant matrices for functional value-added compounds byproduct production. A comparison the methods showed CO2 (SC-CO2) to be more reliable despite some limitations challenges terms yield solubility bioactive when applied processing industries. However, these can solved by using ionic liquids as a trainer or cosolvent during process. The choice over organic solvents used enhance is based properties such hydrophobicity, polarity selectivity addition safe environment.

Occurrence and distribution of endocrine disrupting chemicals and pharmaceuticals in the river Bouregreg (Rabat, Morocco)

Chemosphere, Journal Year: 2021, Volume and Issue: 287, P. 132202 - 132202

Published: Sept. 8, 2021

In this work, Moroccan surface waters were analysed for 27 endocrine disrupting chemicals and pharmaceutically active compounds. The study area was selected on the grounds of scarcity information about contamination status rivers in Rabat region, which receive micropollutants from municipal industrial wastewater, runoff agricultural fields. fact, animal feed residues, urban water untreated waste discharges into old landfills reach river an with a population ca. 3 752 800 where more than 99% all drinking is obtained water. Samples collected at five different sites upstream downstream Bouregreg target compounds determined by using continuous solid-phase extraction system gas chromatography–mass spectrometry. Unlike pharmaceuticals, most EDCs (specifically, 4-tert-octylphenol, nonylphenol, 4-phenylphenol, 2-phenylphenol, estrone, 17β-estradiol, triclosan bisphenol A) present samples detection frequencies above 68%, highest concentrations (142–368 ng/L) being those mouth. pharmaceuticals found encompassed therapeutic classes their ranged 2.5 to 351 ng/L. Overall, abundant class anti-inflammatory/analgesic drugs high (80%), followed antibiotics anti-epileptics (64%), lipid regulators (56%) β-blockers (12%). Based principal component analysis, distribution emerging contaminants studied among sampling consistent physico–chemical properties water, heavily contaminated close mouth river.
