Corrigendum to ?Benzo[a]pyrene is associated with dysregulated myelo-lymphoid hematopoiesis in asthmatic children? [Environ. Int. 128 (2019) 218?232]

This study investigated the sorption of phenanthrene (as a representative PAH) by cation-modified montmorillonites (Ca-MMT and Fe-MMT) under the influence of Glomalin-related soil protein (GRSP) fractions (EE-GRSP and T-GRSP). Batch sorption studies were carried out as a function of GRSP concentrations (0?500?mg/L), results suggested that the sorption capacities of Ca-MMT and Fe-MMT for phenanthrene were greatly enhanced. The phenanthrene sorption isotherms were in good agreement with the Linear and Freundlich models (R2?=?0.886?0.999). The Kd values increased from 4.14 to 60.76?L/kg for Ca-MMT and from 15.57 to 153.80?L/kg for Fe-MMT with the GRSP concentrations adding from 0 to 500?mg/L, respectively. Furthermore, the sorption of phenanthrene was higher on Fe-MMT than that on Ca-MMT. It is believed that GRSP developed a higher sorption level on Fe-MMT, resulting in higher phenanthrene sorption. Microscopic and Spectroscopic analyses confirmed that the effects of GRSP on phenanthrene sorption were attributed to the changes in the surface structure and the hydrophobic property of montmorillonites. In the sorption process, GRSP may sorb onto montmorillonites through cation-? interaction when a bridge linkage was formed, and phenanthrene bound with GRSP mainly via ?-? electron donor-accepter interaction. The findings could provide an in-depth understanding of the ecological functions of GRSP and provide new insights into the pathways of PAH transport and fate in the contaminated fields.
