“…Therefore industrial and municipal wastewater and landfill leachates have to be considered as point sources of BPA. In recent works the presence of BPA have been documented in different matrices such as: sewage sludge, effluents from wastewater treatment plant, river water and landfill leachate [1][2][3][4]. The results provided by Gibson et al from Mexico City wastewaters showed concentrations of BPA ranged from 0.77 to 2.5 µg/dm 3 [4].…”

Wide use of bisphenol A (BPA) in production of polycarbonates and plastic food packaging cause increase of concentration of BPA in the environment. Both in surface water, underground water and seawater BPA was frequently detected in different concentrations. Emerging problem is adsorption of BPA on sewage, because it could be considered as an additional source of pollution, if it is used as a fertilizer in agricultural sectors. Absorbed BPA on sewage sludge stays persistent in the environment and generates adverse biological effects in endocrine system. Because of ecological safety, exploration of potential techniques to remove BPA to the level, which does not give adverse effect on natural environment is necessary. In this study the adsorption of BPA from simulated water onto commercial activated carbons was investigated. On the basis of experimental data the kinetics and type of sorption were determined.

“…Little is known about the degree of exposure of human and other mammals to octylphenol. Estimated daily intake is up to 300 pg.kg -1 body weight (Lee et al, 2002). Collectively, these studies suggest that octyplhenol induces abnormities in male reproductive system.…”

Octylphenol is biodegradation product of alkylphenolethoxylates frequently used in detergents, paints and other industrial applications. This compound is classified as an endocrine disruptor. Recent studies have hypothesized that occupational exposure to octylphenol poses adverse effects on reproductive system of humans and wildlife species. Enzymes involved in the steroid biosynthesis pathway are really sensitive targets for the action of various endocrine-disrupting chemicals. Aim of in vitro study was determined the effect of 4-octylphenol on basal and human chorionic gonadotropin stimulated testosterone formation of ICR mice Leydig cells. On the other hand, was classified potential impact of mentioned endocrine disruptor on Leydig cell viability after 44 h of cultivation. Cell suspension was cultured with addition of 0.04; 0.2; 1.0; 2.5 and 5.0 µg*mL -1 of 4-octylphenol and compared to the control. Hormone quantification from the medium was performed by enzyme-linked immunosorbent assay. Viability of cell suspension was determined by the metabolic activity assay. Unstimulated testosterone production significantly (P˂0.001) increased with 2.5 and 5.0 µg*mL -1 4-octylphenol. Cell viability was also significantly (P˂0.001; P˂0.05) stimulated by 4-octylphenol. Although human chorionic gonadotropin stimulated testosterone secretion was significantly (P˂0.05) affected by the lowest concentration (0.04 µg*mL -1 ) in the cell viability was recorded significantly (P˂0.001; P˂0.05) higher mitochondrial activity (1.0; 2.5 and 5.0 µg*mL -1 ). Considerably more detailed and systematic research in this area is required for a better understanding of potential risk to humans or animals. , 2016, 17(4), p.1274-1286 DOI: 10.5513/JCEA01/17.4.1844 Keywords: Leydig cells, mice, octylphenol, testosterone1274 Journal of Central European Agriculture, 2016, 17(4), p.1274-1286 1274 Journal of Central European Agriculture AbstraktOctylphenol je biodegradačný produkt alkylphenol-ethoxylátov, ktorý je široko využívaný v detergentoch, farbivách a ďalších industriálnych produktoch. Zároveň je klasifikovaný ako endokrinný disruptor. Nedávne štúdie poukazujú na fakt, že pôsobenie octylphenolu vyvoláva negatívne účinky v reprodukčnom systéme ľudí a zvierat. Enzýmy, ktoré sú zapojené do procesu biosyntézy steroidov sú veľmi citlivé na pôsobenie endokrinných disruptorov. Táto in vitro štúdia bola zameraná na sledovanie účinku 4-octylphenolu na bazálnu a hCG stimulovanú produkciu testosterónu u ICR myších Leydigových buniek. Rovnako bol klasifikovaný účinok spomínaného endokrinného disruptora na viabilitu týchto buniek po 44 hodinovej kultivácií. Bunková suspenzia bola kultivovaná s prídavkom 0,04; 0,2; 1,0; 2,5 a 5.0 µg*mL -1 4-octylphenolu a porovnávaná s kontrolou. Kvantifikácia množstva testosterónu bola vykonávaná priamo z média pomocou imunoanalýzy. Pre stanovenie viability Leydigových buniek bol využitý MTT test. Bazálna produkcia testosterónu bola signifitantne (P˂0.001) zvýšená v koncentráciách 2,5 a 5,0 µg*mL -1 4-octylphenolu....

Consumer-grade polyurethane foam functions as a large and selective absorption sink for bisphenol A in aqueous media

et al. 2015

This study for the first time reports the unusual sorption capabilities of polyurethane foam (PUF) for bisphenol A (BPA)a major industrial plasticizer and endocrine-disrupting chemical ubiquitously detected in environmental waters. The low surface-area material showed not only anomalously high sorption capacities, but also rapid uptake for BPA compared with activated carbon and macroreticular polymeric adsorbents. BPA sorption by PUF was driven by a solid-phase partitioning mechanism assisted by hydrogen bonding on PUF lone-pair donor groups. Using high-resolution electron microscopy, gas pycnometry, and cross-sectional infrared imaging analyses, we present new direct evidence for the partitioning of large organic sorbate into PUF through aqueous sorption: volumetric swelling of PUF fibrils induced by BPA uptake, thorough diffusion of BPA inside PUF fibrils, and hydrogen bonds between BPA and PUF carbonyl and ether oxygen groups. Building on this improved understanding of PUF sorption mechanism, we elucidated the specificity of PUF sorption by examining its sorption behaviors under different water chemistry. Quantitative recovery of BPA was readily achieved by exploiting the reversibility of PUF sorption in alkaline solutions. This work provides the first proof of concept on PUF as a large and selective absorption sink for BPA, and demonstrates the potential use of this inexpensive, easily accessible material as a superior sorbent medium for BPA in aqueous media. † Electronic supplementary information (ESI) available: Energy dispersive X-ray spectra, model tting details, supplementary sorption data, electron microscopy images, infrared spectra, breakdown graphs of sorption selectivity data, BPA ionization prole, reusability and material integrity testing data, material information and physical properties, literature survey data.
