Non-conventional sorption materials for the removal of legacy and emerging PFAS from water:A review

Per-and polyfluoroalkyl substances(PFAS)are a class of ubiquitous,persistent,and hazardous pollutants that raise concerns for human health and the ***,PFAS removal from water relies on adsorption techniques using conventional sorption materials like activated carbons(ACs)and ion exchange resins(IERs).However,there is a continuous search for more efficient and performing adsorbent materials to better address the wide range of chemical structures of PFAS in the environment,to increase their selectivity,and to achieve an overall high adsorption capacity and faster uptake *** this context,results from the application of non-conventional sorption materials(i.e.,readily available biological-based materials like proteins and advanced materials like nanocomposites and cyclodextrins)are reported and discussed in consideration of the following criteria:i)removal efficiency and kinetics of legacy PFAS(e.g.,PFOA,PFBA)as well as newly-introduced and emerging PFAS(e.g.,GenX),ii)representativity of environmental conditions in the experimental setup(e.g.,use of environmentally relevant experimental concentrations),iii)regenerability,reusability and applicability of the materials,and iv)role of the material modifications on PFAS *** this review,it emerged that organic frameworks,nano(ligno)cellulosic-based materials,and layered double hydroxides are among the most promising materials herein investigated for PFAS adsorption,and it was also observed that the presence of fluorine-and amine-moieties in the material structure improve both the selectivity and PFAS ***,the lack of data on their applicability in real environments and the costs involved means that this research is still in its infancy and need further investigation.

Genetic diversity in old populations of sessile oak from Calabria assessed by nuclear and chloroplast SSR

引用

Journal of Mountain Science 2019年第5期16卷 1111-1120页

作者： antonio LUPINI Meriem Miyassa ACI antonio MAUCERI Giuseppe LUZZI Silvio BAGNATO Giuliano MENGUZZATO francesco MERCATI francesco SUNSERI Department of AGRARIA Mediterranea University of Reggio Calabria Sila National Park Via Nazionale snc National Research Council of Italy Institute of Biosciences and Bioresources (CNR-IBBR)

In the framework of forest resources conservation, this study aims to understand the dynamic and the genetic structure of sessile oak forests in Calabria, Italy. Two old populations of sessile oak(Quercus petraea(Mattuschka) Liebl.) from two areas of Sila and Aspromonte massifs in Calabria were analyzed for genetic diversity and population structure based on 6 nuclear simple sequence repeat(nSSR) and 4 chloroplastic SSR(cpSSR) loci. The populations displayed high amount of genetic diversity, which was toughly structured according to their geographical origins. Number of alleles at SSR loci ranged from 11 to 20 with an average of 13.5 per locus. Gene diversity(expected heterozygosity, He) estimates ranged from 0.575 to 0.834 with a mean of 0.749. The observed heterozygosity(Ho) was on average 0.458 ranging from 0.150 to 0.682. Polymorphism information content(PIC) values ranged from 0.625 to 0.865 with an average of 0.787. The analysis of molecular variance(AMOVA) highlighted a significant higher estimated variance within populations compared to among populations. Finally, the analysis of haplotypes by using cpSSR suggested a higher diversification in the population from Sila. Hierarchical clustering analysis grouped the genotypes into two major clusters, which agreed with the geographic origin of populations, and was confirmed by the Discriminant Analysis of Principal Components(DAPC). The first cluster included plants/population from Sila massif, while the second encompassed mostly plants/population sampled in Aspromonte massif. Finally, model-based clustering by STRUCTURE analysis also supported the presence of clear genetic structuring in the collection with two major populations(K=2) supported to PCoA analysis as well. Finally, our data indicated the Aspromonte population as a marginal forest with fragmented distribution suggesting different strategies of preservation than in Sila massif.
