    Abstract To analyze the pollution levels and health risk assessment of Polycyclic Aromatic Hydrocarbons (PAHs) and their derivatives (SPAHs) in five typical effluents from sewage treatment plants and receiving rivers in Beijing, the concentrations of PAHs and SPAHs in samples were measured by the combined method of solid extraction and gas chromatography-mass spectrometry. The distribution characteristics were also analyzed. At the same time, the probabilistic health risk was assessed using toxic equivalent factors. The results show that the contamination of PAHs and SPAHs in five typical effluents from sewage treatment plants and receiving rivers in Beijing is 75-584 ng·L

    Abstract Like their parent polycyclic aromatic hydrocarbons (PAHs), substituted polycyclic aromatic hydrocarbons (SPAHs), including methyl PAHs (MPAHs), oxygenated PAHs (OPAHs), and chlorinated PAHs (ClPAHs), exist ubiquitously in urban and agricultural rivers. Although laboratory studies have found the biological toxicities of certain SPAHs to be higher than that of their parent PAHs, the ecological risk of SPAHs in rivers has been largely ignored. Here, we studied the distribution, source and transport of PAHs and SPAHs as well as ecological risks in the Chaobai River System, which experiences a high level of anthropogenic activity. The results show that the concentration of ΣOPAHs (321 ± 651 ng/L) was higher than that of ΣPAHs (158 ± 105 ng/L), ΣMPAHs (28 ± 22 ng/L), and ΣClPAHs (30 ± 12 ng/L). We also found that (S)PAHs in Chaobai River mainly originated from Beiyun River (53%–65%), which receives considerable municipal wastewater treatment plant effluent from Beijing. The major transport pathway of (S)PAHs from Chaobai River was likely for irrigation (83%–86%) and transportation into Yongdingxin River (13%–16%), which finally merged into the Bohai Sea. The mixed chronic risk of (S)PAHs (risk quotient = 45 ± 53) was higher than the mixed acute risk (risk quotient = 1.9 ± 1.4), with all sites facing chronic risk and 90% of sites experiencing acute risk. Although the chronic and acute risks of (S)PAHs to plants, invertebrates, and vertebrates were mainly from PAHs (97.5% to chronic risk and 96.5% to acute), SPAHs still posed a chronic risk to invertebrates and vertebrates (risk quotient > 1). Accordingly, the ecological risk of (S)PAHs in Chaobai River should be taken into consideration for ecosystem protection. The transmission of PAHs and SPAHs from Chaobai River may also pose potential risks to farmland through irrigation, as well as to the Bohai Sea via river water discharge.

    Abstract Ecological wastewater treatment plant (EWWTP), a kind of emerging wastewater treatment plant (WWTP) in recent years, combined microbiology with botany which is efficient for the removal of nitrogen and organic matter, as well as deodorization. The occurrence and removal of micro-organic pollutants in EWWTPs were still not well known. Polycyclic aromatic hydrocarbons (PAHs) and their typical derivatives (SPAHs) including the oxygenated PAHs (OPAHs), chlorinated PAHs (ClPAHs), and methyl PAHs (MPAHs) were investigated in an EWWTP in Guangdong Province, China. The concentrations of the Σ6 OPAHs (114–384 ng/L) were higher than the Σ16 PAHs (92–250 ng/L), and much higher than the Σ4 MPAHs (13–64 ng/L) and Σ9 ClPAHs (2–3 ng/L) in the EWWTP and the effluent receiving river. The total removal efficiencies of the PAHs, OPAHs, MPAHs, and ClPAHs in the EWWTP (43 ± 14%, 41 ± 7%, 55 ± 16%, and 18 ± 4%) were lower than the traditional WWTPs, probably due to the lower concentration of the sludge in the ecological treatment. The advanced treatment process (microfiltration and UV disinfection treatment) contributed much less (0–20%) to the whole removal efficiency than the ecological treatment (80–100%). The effluent from the EWWTP slightly reduced the PAHs and SPAHs concentrations in the receiving river. The high concentrations of the PAHs and SPAHs in the receiving river were similar to the influent of the EWWTP, indicating that some untreated wastewater was directly discharged to the river, especially in the upstream.
