Despite a wealth of information on the accumulation of MPs in aquatic species, there is no information on the uptake and accumulation of MPs by higher plants. Terrestrial edible plants are directly exposed to MPs when agricultural soil was applied with organic manure, sewage sludge as fertilizer or plastic mulching. In this paper, the uptake of two sizes of polystyrene (PS) microbeads (0.2 and 1.0 mum) and then their distribution and migration in an edible plant lettuce were firstly investigated based on laboratory experiments. We used fluorescent markers to track PS microbeads in plant tissues and found fluorescence to be a sensitive and reliable detection method. Sections from untreated control lettuce showed no autofluorescence. When roots were treated with fluorescently labeled PS microbeads, the microbeads could be identified by its fluorescence. Our main study investigated the uptake of 0.2 mum beads, as few luminescence signals were observed in lettuce roots for 1.0 mum beads in our experiment. We observed that 0.2 mum fluorescent microbeads were extracellularly trapped in the root cap mucilage (which is a highly hydrated polysaccharide) and a dark green tip (which was typical of lettuce roots exposed to label PS beads) was usually visible to the naked eye. Confocal images revealed that the PS luminescence signals were mainly located in the vascular system and on the cell walls of the cortex tissue of the roots, indicated that the beads passed through the intercellular space via the apoplastic transport system. Once inside the central cylinder, the 0.2 mum PS beads were transferred from the roots to the stems and leaves via the vascular system following the transpiration stream. We also observed that the PS beads adhered to one another and self-assembled systematically into grape-like and (chain) string-like clusters in the intercellular space of the root and stem vascular tissue of lettuce plant. In contrast to the root and stem, PS beads were dispersed in the leaf tissue. Here, for the first time we provide evidence of the adherence, uptake, accumulation, and translocation of submicrometer MPs within an edible plant. Our findings highlight the previously underappreciated human exposure pathway to MPs through the consumption of contaminated crops and emphasize the need for new management strategies to control the release of MPs waste products into the terrestrial environment. Ultimately, the potential impacts of low range sized MPs on food safety of crop plants and human health need to be urgently considered.   Comparative effects of biochar-nanosheets and conventional organic-amendments on health risks abatement of potentially toxic elements via consumption of wheat grown on industrially contaminated-soil 期刊论文  OAI收割 CHEMOSPHERE, 2018, 卷号: 192, 期号: 2018, 页码: 161-170 作者:  Ullah, Habib;  Yousaf, Balal;  Liu, Guijian;  Abbas, Qumber;  Wang, Ruwei   |  收藏  |  浏览/下载：114/0  |  提交时间：2018/09/25 Biochar Nanosheets  Soil  Pte-contamination  Bioavailability  Wheat Consumption  Human Health Risks   Addition of biochar nanosheets to soil alleviate health risks of potentially toxic elements via consumption of wheat grown in an industrially contaminated soil 期刊论文  OAI收割 ACCEPTED MANUSCRIPT, 2017, 期号: 2017 作者:  Yousaf,B(Yousaf,Balal);  Liu,GJ(Liu,Guijian);  Abbas,Q(Abbas,Qumber);  Ullah,H(Ullah,Habib);  Wang,RW(Wang,Ruwei)   |  收藏  |  浏览/下载：118/0  |  提交时间：2018/10/26 Biochar Nanosheets  Soil  Pte-contamination  Bioavailability  Wheat Consumption  Human Health Risks   Sustainability assessment of one industrial region: A combined method of emergy analysis and IPAT (Human Impact Population Affluence Technology) 期刊论文  OAI收割 ENERGY, 2016, 页码: 818-830 作者:  Yu, Xiaoman;  Geng, Yong;  Dong, Huijuan;  Ulgiati, Sergio;  Liu, Zhe 收藏  |  浏览/下载：54/0  |  提交时间：2016/12/06 Resource consumption  Driving forces  Emergy  IPAT (Human Impact Population Affluence Technology)  Liaoning province   Urbanization and Sustainability: Comparison of the Processes in "BIC" Countries SCI/SSCI论文  OAI收割 2016 作者:  Zeng C.;  Deng, X.
