“…Limited by an appropriate quantification analytical method, few studies have focused on investigating the depuration of mixture CdS/ZnS QDs located on the root epidermis. Inductively coupled plasma-mass spectrometry (ICP-MS) has long been considered as an effective approach to determine trace concentrations of metalbased QDs in environmental samples, including water, soil/sediment and biota [22][23][24]. However, the ICP-MS method does not yet possess the spatial resolution required for completely degraded QDs in environmental samples, which occurs during pretreatment procedures, [25,26] and thus, the method cannot quantify this fraction of metal-based QDs.…”

Background: The depuration fate of mixtures of metal-based quantum dots (QDs) in root epidermis is an important factor that determined their follow-up transportation and transformation processes in plant. However, the related mechanisms are poorly understood due to the lack of appropriate quantitative methods. Results:In our study, a novel method for in situ determination of mixtures of CdS/ZnS QDs with different surface coatings located on root epidermis was developed using an excitation-emission matrix combined with multi-way parallel factor analysis (PARAFAC) and n-way partial least squares (n-PLS). Then, the fates of CdS/ZnS QDs on mangrove and wheat root epidermis were investigated using the established method. During the rapid dissipation stage, intracellular and intercellular degradation of metal ions instead of transportation and rhizophytic bacteria degradation was the predominant reasons for the reduction in the CdS/ZnS QDs mixtures. However, due to vertical migration of CdS/ZnS QDs in the slow depuration stage, negative linear relationships were observed between the K s values of oleic acid-CdS/ZnS QDs and the polarity index of the root epidermis (p < 0.05), which further indicated a difference between the single and mixture QDs. Conclusions:To our knowledge, this study provided a new approach to investigate the fate of QDs located on root epidermis and revealed the related mechanisms. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

The article is basically an attempt to provide a consolidated report on impact assessment and trends in research pertaining to accumulation and curbing the menace of polyaromatic hydrocarbon (PAH) accumulation in leaves. Emphasis is given to understand the consequences of the fact that edible/medicinal plants cultivated in PAH contaminated soil or close to such places which are potential liberators of PAHs can virtually act as transporters for direct PAH entry into biological systems. An attempt has been made to predict the future by digging out golden facts from history. Extensive Scopus-based data mining has been done to dig out research data since last 10 years (2006-2016) pertaining to the said area. Critical analysis of statistical data on research trends highlighting the different aspects of evaluation of PAH accumulation in leaves has been described. The concentrate of all researches for the said period have been presented as few golden principles which shall serve as important facts for researchers and policy makers for curbing the menace of PAH-induced oxidative stress in plants and shall also provide start-up ideas for researchers new to the area. Critical analysis of trends in phytoremediation aspect has also been duly highlighted to measure the intensity of restoration steps taken by researchers and government to safeguard the future generations.
