Revolutionary trapping experiments indicated that SO4- had been the principal radical for TC-HCl removal while OH has also been included. In inclusion, LaFeO3 was shown with excellent security and reusability in degrading TC-HCl particles into the Vis/LaFeO3/PS system. The conclusions with this work disclosed the possibility application of this Vis/LaFeO3/PS system toward degrading natural toxins in wastewater. As a persistent organic pollutant, polycyclic aromatic hydrocarbons (PAHs) may still residually pollute professional sites after moving. This study investigated the contamination status of PAHs into the topsoils of three professional history web sites (the Shougang manufacturing damages, the original Beijing coking plant area, and an abandoned gas section) that relocated significantly more than ten years ago from downtown Beijing. The sources of PAHs when you look at the earth had been qualitatively and quantitatively examined, and health problems had been evaluated for various groups of people. The total focus of 16 PAHs within the research location ranged from 371.1 ng g-1 to 4073.9 ng g-1. The pollution degrees of the three study places had been abandoned gas station > Beijing coking plant > Shougang damages. With regards to composition, low-ring aromatics taken into account most of the detected PAHs, plus in the dry season, low-ring aromatics accounted for a greater percentage into the three places than in the wet season. The comparison of the PAH diagnostic ratio and PMF design verification showed that the resources of PAHs into the Shougang ruins therefore the Beijing coking plant location were mainly those of biomass and coal burning, accounting for 66.3% and 56.1% of the complete detected PAH
