“…The plant uptake of persistent organic pollutants (POPs) from environmental matrices has attracted research interest because plants are the primary point of entry for pollutants into the food chain. , In particular, the root–soil boundary region, generally referred to as the rhizosphere, represents the most important biotic–abiotic mass-transfer interface and plays an important role in the dissipation of pollutants in soil and plant uptake of soil pollutants . Plants can enhance the removal of organic pollutants through adsorption or uptake by roots or through biodegradation or rhizoremediation .…”

The distribution and composition of polychlorinated biphenyls (PCBs) within soil–plant systems around a notorious e-waste recycling site were investigated. The average total PCB concentrations in rhizospheric soils (RSs) and nonrhizospheric soils (NRSs) were 2160 and 1270 pg g–1 dry weight (DW), respectively. PCBs were more enriched in RS than NRS for most vegetable species. PCB accumulation in plant tissues varied greatly among plant cultivars, ranging from 4020 to 14 500 pg g–1 DW in shoots and from 471 to 24 400 pg g–1 DW in roots. The compositions of PCBs in soil and plants showed that hexa- and hepta-chlorinated PCBs were preferentially accumulated in soils, while tri- and tetra-PCBs were abundant in plant tissues. These results indicated that low-chlorinated PCBs might be prone to accumulation and transfer within plants, which was confirmed by the relationship between the root concentration factor and octanol–water coefficient. The first eluting enantiomers of PCB 84 and PCB 95 were preferentially transferred between the soil and plants, while the stereoselectivity of PCB 136 varied among plant species. A significant difference in enantiomeric fractionation of PCB 84 between the soil and roots indicated that enantiomeric enhancement of PCB 84 occurred during its translocation from soil to root, whereas no such difference was observed in these chiral PCBs during their translocation from the root to the shoot.

“…In a tree bark study near an active electronics recycling facility in Luqiao, China, Wen et al 9 found a mean ∑PCB (194 triCB through decaCB congeners) value of 6 500 000 pg g −1 lipid, about nine times greater than our mean value in Sauget (717 000 pg g −1 lipid). Odabasi et al 39 report industrial average ∑PCB (41 congeners) concentrations at Aliaga, Turkey, of 808 000 pg g −1 lipid, while the "background" amount averaged 53 400 pg g −1 lipid. The industrial average is consistent with the average at Sauget, while the lowest concentration at Sauget is ∼3.6 times greater than the "background" value at Aliaga.…”

“…Some recent investigations regarding organic contaminants in tree bark do not report values normalized to lipid content, claiming that contaminant amount and lipid content are not well correlated. 39 This correlation is based on an assumption that all trees sampled have had the same level of exposure to the given contaminant. In our earlier work on PCDD/PCDF from Sauget, 1 we show that contaminant amounts are variable by a factor of 5 over distances as short as 150 m, showing that this assumption is not valid for our application.…”

We collected 27 tree bark samples near Sauget, IL, where 373 000 mt of polychlorinated biphenyls (PCB) was produced between 1936 and 1977 and 10 245 mt was incinerated from 1971 to 1977. Our goal was observe PCB distribution and apparent movement to residential sites, where 24 of 27 samples were collected. Only one of several waste sites was accessible for sampling. We analyzed for 209 PCB congeners, and 85 peaks are reported (other congeners either coeluted or were near or less than the detection limit). Concentrations of ∑PCB ranged from 190 952 to 2 383 988 pg g lipid(-1); 24 of 27 samples had less than 50% of the maximum concentration. Two samples with the highest ∑PCB concentrations were downwind from the plant site in residential areas, but both were among the farthest away from the production facility. One high-concentration sample was near the waste site. The three highest concentrations were in trees that were less than 20 years old, showing recent atmospheric PCB mobility. The percentage of ∑PCB distributions showed a consistent but variable pattern of diCB to nonaCB congeners. DecaCB was inconsistent, because PCB-209, which was manufactured at the site in Aroclor 1270 and 1271, was the most abundant congener in 10 of the samples but lower in others.

Industria eta teknologiaren garapenak ezaugarri fisiko-kimiko bereziak dituzten material berriak sortzea eragin du, hauen artean, nanomaterialak (NMak), mikroplastikoak (MPak) eta nanoplastikoak (NPak) gero eta ugariagoak dira. NMak gutxienez nanoeskaladun (<100 nm) dimentsio bat duten materialak dira; MPak, 5 mm baino txikiagoak diren plastikozko materialak dira eta NPak, 100 nm baino txikiagoak direnak. Gaur egun, Europako legedian ez dago NMentzako araudi berezirik, nahiz eta beraien homologo makroskopikoekin alderatuta, ezaugarri fisiko-kimiko ezberdinak agertu. NMak, MPak eta NPak iturri desberdinetatik itsasora iristen dira eta beraz, itsas organismoetan eragin ditzaketen kalteen inguruko kezka zabaldu da. Gainera, NMek, MPek eta NPek duten azalera-bolumen erlazio handia eta hidrofobizitatea dela eta, arrisku gehigarri bat dute: kutsatzaile organiko iraunkorren (ingelesetik POP) garraiatzaile gisa joka dezakete itsasoan. Hau da, NMek, MPek eta NPek itsasoan dauden POPak adsorbatu ditzakete eta hauen eskuragarritasuna emendatu organismo itsastarrentzat. Gure ikerketen xedea, karbonoan oinarritutako NMek (grafenoa eta karbono-nanohodiak), MPek eta NPek hainbat espezie itsastarretan eragindako kalte fisiologikoak, zein zelula eta molekula mailako kalteak aztertzea da. Kalte horiek, POPdun NM, MP eta NPek eragindako kalteekin alderatu nahi dira ere. Orain arte burututako esperimentuetan, MPdun janariarekin elikatutako muskuiluek, urdailaren argian, liseri epitelioan eta ehun konektiboan agertu dituzte MPak. Gainera, benzo(a)pirenoa (BaP) moduko POPa adsorbatuta duten MPdun mikroalgekin elikatutako muskuiluek, BaPa metatzen dute ehunetan. Bai MPek bakarrik zein POPdun MPek immunotoxizitatea, kalte fisiologikoak eta DNA mailako kalteak eragin dizkiete muskuiluei. Itsasoa bezalako ingurune konplexu batean, kutsatzaileak ez dira modu isolatuan agertzen eta beraz, ezagutza hau kontuan hartu beharko litzateke, itsas ekosistemen osasuna eta segurtasuna bermatzeko.
