Pharmaceuticals and personal care products (PPCPs) can reach soil and aquatic environments through land application of wastewater effluent and agricultural runoff. The objective of this research was to assess the fate of PPCPs at field scale. PPCPs were measured systematically in a wastewater treatment plant (WWTP), and in soil and groundwater receiving treated effluent from the WWTP. A land application site in West Texas was used as the study site; it has received treated wastewater effluent from the WWTP for more than 70 years in order to remove additional nutrients and irrigate non-edible crops. Target compounds (estrone, 17??-estradiol, estriol, 17??-ethynylestradiol, triclosan, caffeine, ibuprofen, and ciprofloxacin) in wastewater, sewage sludge, soil, and groundwater were determined using HPLC/UV with qualitative confirmatory analyses using GC/MS. Samples were collected quarterly over 12 months for wastewater and sludge samples and over 9 months for soil and groundwater samples. Results indicated that concentrations of PPCPs in wastewater influent, effluent, sludge solid phase, and sludge liquid phase were in the range of non-detected (ND)-183 ??g/L, ND-83 ??g/L, ND-19 ??g/g, and ND-50 ??g/L, respectively. Concentrations in soil and groundwater samples were in the range of ND-319 ng/g and ND-1,745 ??g/L, respectively. GC/MS confirmation data were consistent with the results of HPLC/UV analyses. Overall, data indicate that PPCPs in the wastewater effluent from the WWTP transport both vertically and horizontally in the soil, and eventually reach groundwater following land application of the effluent.  相似文献

The effect of different Cr and Zn concentrations in the soil on the development of Albares wheat and Pedrezuela barley plants at the physiological, biochemical, and structural levels was evaluated during the crop cycle in a greenhouse assay, as well as their potential use in phytoremediation strategies. The accumulation of Cr and Zn in plants was dose-dependent for both cultivars. The highest contents were found in root and the lowest in grain. In the Cr treatments, the decrease with respect to the control in the biomass, relative water content (RWC), chlorophyll content (Chl), and chlorophyll fluorescence values (Fv/Fm) was more pronounced in wheat than in barley. For the Zn treatments, the behavior was the opposite. Barley showed less tolerance to Zn concentrations although its higher translocation factor (TF) and greater biomass make this plant adequate to use in phytoremediation process in soil contaminated with Zn. The electron microscopy studies showed evidence that treatment with both Cr and Zn produced alterations in the cellular ultrastructure of the plant leaves. Cr and Zn induced the production of malondialdehyde (MDA) in both cultivars; the highest concentrations were observed in barley leaves. In general, the ascorbate peroxidase activity (APX) was higher in the plants exposed to metal treatments. The catalase activity (CAT) showed a different behavior depending on the metal studied. These results highlight the potential capacity of Albares wheat for use in the phytoremediation of soils contaminated by Zn and of Pedrezuela barley for use in Cr- and Zn-contaminated soils.

Purpose  

Recently, pharmaceuticals and personal care products (PPCPs) have been identified in the environment. Concerns on the occurrence and fate of these compounds in soil and sediment have significantly increased. It is believed that these PPCPs sorb to soil and sediment; however, information on sorption of PPCPs is still limited. In this study, the sorption of estrone (E1), 17β-estradiol (E2), estriol (E3), 17α-ethynylestradiol (EE2), triclosan, and caffeine to two loam soils and Ottawa sand was assessed.  相似文献
