| 1 | Polycyclic aromatic hydrocarbons in soils of Beijing and Tianjin region: Vertical distribution, correlation with TOC and transport mechanism显示文摘The contents and distribution of 20 polycyclic aromatic hydrocarbons (PAHs) and heterocyclic aromatic hydrocarbons (HAHs) were investigated in 16 soil profiles of Beijing and Tianjin region. Transport of high molecular weight PAHs (HMWPAHs) and the correlation between total organic carbon (TOC) and their concentrations were also discussed. The results indicated that highly contaminated sites were located at urban or wastewater irrigation areas and pollutants mainly accumulated in topsoil (< 40 cm), with a sharp content decrease at the vertical boundary of 30-40 cm. Total PAHs/HAHs concentrations in soils from Tianjin were markedly greater than those from Beijing. Even the contents at bottoms of soil profiles in Tianjin were higher than those in topsoils of Beijing soil profile. HMWPAHs dominated the PAH profiles, exhibiting a uniform distribution of pyrogenic origin between topsoils and deep layers. Furthermore, the percentages of HMWPAHs remained relative constant with the depth of soil profiles, which were consistent with the distribution of particulate matter-associated PAHs in the local atmospheric environments. Therefore, HMWPAHs transport with particulates might be the predominant source found in soil profiles. | HE Fengpeng ZHANG Zhihuan WAN Yunyang LU Song WANG Liang BU Qingwei | 2009 | Journal of Environmental Sciences2009，21，5： | 34 |

| 3 | Emerging Organic Contaminants in Chinese Surface Water:Identification of Priority Pollutants显示文摘The occurrence and impacts of emerging organic contaminants(EOCs)in the aquatic environment have gained widespread attention over the past two decades.Due to large number of potential contaminants,monitoring campaigns,treatment plants,and proposed regulations should preferentially focus on specific pollutants with the highest potential for ecological and human health effects.In the present study,a multi-criteria screening approach based on hazard and exposure potentials was developed for prioritization of 405 unregulated EOCs already present in Chinese surface water.Hazard potential,exposure potential,and risk quotients for ecological and human health effects were quantitatively analyzed and used to screen contaminants.The hazard potential was defined by contaminant persistence,bioaccumulation,ecotoxicity,and human health effects;similarly,the exposure potential was a function of contaminant concentration and detection frequency.In total,123 compounds passed the preselection process,which involved a priority index equal to the normalized hazard potential multiplied by the normalized exposure potential.Based on the prioritization scheme,11 compounds were identified as top-priority,and 37 chemicals were defined as high-priority.The results obtained by the priority index were compared with four other prioritization schemes based on exposure potential,hazard potential,or risk quotients for ecological effects or human health.The priority index effectively captured and integrated the results from the more simplistic prioritization schemes.Based on identified data gaps,four uncertainty categories were classified to recommend:①regular monitoring,derivation of environmental quality standards,and development of control strategies;②increased monitoring;③fortified hazard assessment;and④increased efforts to collect occurrence and toxicity data.Overall,20 pollutants were recommended as priority EOCs.The prioritized list of contaminants provides the necessary information for authoritative regulations to monitor,control,evaluate,and manage the risks of environmentally-relevant EOCs in Chinese surface water. | Mengmeng Zhong Tielong Wang Wenxing Zhao Jun Huang Bin Wang Lee Blaney Qingwei Bu Gang Yu | 2022 | Engineering2022，8，4： | 3 |

| 6 | Assessing the persistence of pharmaceuticals in the aquatic environment:Challenges and needs显示文摘Chemical’s persistence is known to be an important parameter applied for decades to identify persistent organic pollutants in hazard and/or risk assessments.Nevertheless it is greatly challenged in the case of emerging contaminants such as pharmaceuticals because the persistence of these chemicals could be more affected by environmental conditions.This fact brings more challenges to the current system for evaluating the persistence of chemical contaminants.In this paper,challenges in assessing the persistence of pharmaceuticals were identified,and more importantly research needs were addressed based on the existing data and knowledge. | Qingwei Bu Xiao Shi Gang Yu Jun Huang Bin Wang | 2016 | Emerging Contaminants2016，2，3： | 0 |
| 7 | Assessment of solar-assisted electrooxidation of bisphenol AF and bisphenol A on boron-doped diamond electrodes显示文摘Bisphenol(BP)analogues in wastewater effluent and groundwater pose a potential threat to human health due to their ability to disrupt steroidogenesis.A new solar-assisted electrochemical process(SECP)was developed and evaluated for the degradation of BP analogues.The effects of quenchers,current density,initial pH,supporting electrolyte,and aqueous matrix on the removal kinetics of bisphenol AF(BPAF)and bisphenol A(BPA)were investigated.The kinetic constants of BPAF,BPA,and bisphenol S(BPS)in the SECP with irradiation intensity of 500 mW cm^(-2) were 0.017±0.002 min^(-1),0.022±0.002 min^(-1),and 0.012±0.001 min^(-1),respectively.The changes in the degradation rates of BPAF,BPA,and BPS in the presence of quenchers indicated the relative contribution of hydroxyl radical(·OH)oxidation,anodic electrolysis,and singlet(^(1)O_(2))oxygenation in the degradation of BPs in the SECP.The enhanced rate of generation of ·OH and ^(1)O_(2) was observed in the SECP compared with those in the conventional electrochemical system.The identification of the transformation products(TPs)of BPAF demonstrated that hydroxylation,ring cleavage,b-scission,and defluorination were the major processes during the oxidation in the SECP.The conversion to fluoride ions(76%)and mineralization of total organic carbon(72%)in the SECP indicated further degradation of TPs.The results from this study improved our understanding of the degradation of BP analogues in the electrooxidation irradiated by solar light and help to establish the application potential of the SECP for the effective degradation of emerging contaminants in wastewater. | Jing Ding Lingjun Bu Bingxin Cui Guanshu Zhao Qingwei Gao Liangliang Wei Qingliang Zhao Dionysios D.Dionysiou | 2020 | Environmental Science and Ecotechnology2020，，3： | 0 |
