In this study, 130 surface soil samples were collected at an industrial pollution site in Beijing and the contents of As, Be, Cd, Cu, Cr, Hg, Ni, Pb, Sb, Ti, Zn, and 16 PAHs were determined. The positive matrix factorization (PMF) model was used to analyze the sources of heavy metals and PAHs, and the contributions of these sources to carcinogenic risk and hazard index in the study area were calculated. The results showed that the contents of Cd, Cu, Pb, Hg, As, Zn, and Cr in the soil exceeded the background values in different degrees; C

KGaA, Weinheim.Compared to silica and alumina, graphene has received little attention as catalyst support, although it may represent a good candidate in view of its inertness, its good mechanical and thermal properties and its extended π conjugated system. While lanthanide catalysts grafted on silica have been synthetized and theoretically investigated, the grafting mode of La complexes onto graphene surfaces remains unknown. To shed light on this reaction, we report here a computational density functional theory study on the graftin
