| 2 | Size distribution and diffuse pollution impacts of PAHs in street dust in urban streams in the Yangtze River Delta显示文摘Particles of dust washed off streets by stormwater are an important pathway of polyaromatic hydrocarbons(PAHs) into urban streams.This article presented a comprehensive assessment of the size distribution of PAHs in street dust particles,the potential risks of the particles in urban streams,and the sources and sinks of PAHs in the stream network.This assessment was based on measurements of 16 PAHs from the USEPA priority list in street dust particles and river sediments in Xincheng,China.The content of total PAHs ranged from 1629 to 8986 μg/kg in street dust particles,where smaller particles have a higher concentrations.Approximately 55% of the total PAHs were associated with particles less than 250 μm which accounted for 40% of the total mass of street dust.The PAH quantities increased from 2.41 to 46.86 μg/m2 in the sequence of new residential,rising through main roads,old town residential,commercial and industrial areas.The sediments in stream reaches in town were found to be sinks for street dust particle PAHs.The research findings suggested that particle size,land use and the hydrological conditions in the stream network were the factors which most influenced the total loads of PAH in the receiving water bodies. | ZHAO Hongtao YIN Chengqing CHEN Meixue WANG Weidong Jefferies Chris SHAN Baoqing | 2009 | Journal of Environmental Sciences2009，21，2： | 17 |
| 3 | Performance of pond–wetland complexes as a preliminary processor of drinking water sources显示文摘Shijiuyang Constructed Wetland(110 hm^2) is a drinking water source treatment wetland with primary structural units of ponds and plant-bed/ditch systems. The wetland can process about 250,000 tonnes of source water in the Xincheng River every day and supplies raw water for Shijiuyang Drinking Water Plant. Daily data for 28 months indicated that the major water quality indexes of source water had been improved by one grade. The percentage increase for dissolved oxygen and the removal rates of ammonia nitrogen, iron and manganese were 73.63%, 38.86%, 35.64%, and 22.14% respectively. The treatment performance weight of ponds and plant-bed/ditch systems was roughly equal but they treated different pollutants preferentially. Most water quality indexes had better treatment efficacy with increasing temperature and inlet concentrations. These results revealed that the pond–wetland complexes exhibited strong buffering capacity for source water quality improvement. The treatment cost of Shijiuyang Drinking Water Plant was reduced by about 30.3%. Regional rainfall significantly determined the external river water levels and adversely deteriorated the inlet water quality, thus suggesting that the 'hidden' diffuse pollution in the multitudinous stream branches as well as their catchments should be the controlling emphases for river source water protection in the future. The combination of pond and plant-bed/ditch systems provides a successful paradigm for drinking water source pretreatment. Three other drinking water source treatment wetlands with ponds and plant-bed/ditch systems are in operation or construction in the stream networks of the Yangtze River Delta and more people will be benefited. | Weidong Wang Jun Zheng Zhongqiong Wang Rongbin Zhang Qinghua Chen Xinfeng Yu Chengqing Yin | 2016 | Journal of Environmental Sciences2016，28，1： | 10 |
| 4 | Nitrous oxide reductase gene (nosZ) and N_2O reduction along the littoral gradient of a eutrophic freshwater lake显示文摘Lake littoral zones are characterized by heterogeneity in the biogeochemistry of nutrient elements. This study aimed to explore the relationship between the nitrous oxide reductase gene (nosZ)-encoding denitrifier community composition/abundance and N2O reduction. Five samples (deep sediment, near-transition sediment, transition site, near-transition land and land soil) were collected along a littoral gradient of eutrophic Baiyangdian Lake, North China. To investigate the relationship between the nosZ-encoding denitrifier community structure and N2O reduction, the nosZ-encoding denitrifier community composition/abundance, potential denitrification rate (DNR) and potential N2O production rate (pN2O) were investigated using molecular biological technologies and laboratory incubation experiments. The results showed that the average DNR of sediments was about 25 times higher than that of land soils, reaching 282.5 nmol N/(g dry weight (dw)·hr) and that the average pN2O of sediments was about 3.5 times higher than that of land soils, reaching 15.7 nmol N/(g dw·hr). In the land area, the nosZ gene abundance showed a negative correlation with the N2O/(N2O+N2) ratio, indicating that nosZ gene abundance dominated N2O reduction both in the surface soils of the land area and in the soil core of the transition site.Phylogenetic analysis showed that all the nosZ sequences recovered from sediment clustered closely with the isolates Azospirillum largimobile and Azospirillum irakense affiliated to Rhodospirillaceae in alpha-Proteobacteria, while about 92.3% (12/13) of the nosZ sequences recovered from land soil affiliated to Rhizobiaceae and Bradyrhizobiaceae in α-Proteobacteria. The community composition of nosZ gene-encoding denitrifiers appeared to be coupled with N2O reduction along the littoral gradient. | Chaoxu Wang Guibing Zhu Yu Wang Shanyun Wang Chengqing Yin | 2013 | Journal of Environmental Sciences2013，25，1： | 8 |

| 6 | Shallow groundwater nitrogen responses to different land use managements in the riparian zone of Yuqiao Reservoir in North China显示文摘This field study investigated the nitrogen concentrations in the shallow groundwater from an ephemeral stream and four land uses: cropland, two-year restored (2yr) and five-years restored (5yr) woodlands, fishponds, and the nitrogen flux in the riparian zone of Yuqiao Reservoir. The groundwater nitrate-N concentrations in cropland were the highest among the four land uses. Total dissolved nitrogen (TDN) and nitrate-N concentrations in the 2yr woodland were significantly (p < 0.05) higher than in 5yr woodland. The lowest nitrogen concentrations were detected in fishponds. Nitrate-N was the main form in cropland and 2yr woodland, whereas both nitrate-N and dissolved organic nitrogen (DON) were the main species in 5yr woodland and fishponds. But, ammonium-N was the main form in the ephemeral stream. During the rainy season, the groundwater flow with dissolved nitrogen drains from upland into the reservoir along the hydraulic gradient. The woodland between the cropland and reservoir could act as a buffer to retain shallow groundwater nitrogen. The dominant form of ammonium-N in the groundwater TDN pool in ephemeral stream indicated that nitrogen from the village and orchard in upland flowed into the reservoir via subsurface flow. The fishpond was not an important pollution source for nitrogen transfer via shallow groundwater. | LU Haiming YIN Chengqing | 2008 | Journal of Environmental Sciences2008，20，6： | 3 |

| 19 | Ecological wetland paradigm drives water source improvement in the stream network of Yangtze River Delta显示文摘Jiaxing created a precedent using bypass riparian marshes to purify micro-polluted water sources in China.Pond-wetland complex with constructed root channel technology becomes a paradigm which can be analogized as'human-body wetland model'based on bionics or biomimetics.Heterogeneous plant-bed/ditch system with highly active land/water ecotone interfaces,especially meandering boundaries,breeds many biochemical reactions'living areas'.Optimization of hydraulic regulation promotes redox environment alternations and wetland treatment efficiency.Here we reported a series of upgrades and performances in Guanjinggang wetland after the Shijiuyang prototype.Morphological reform of plant-bed/ditch system played a vital role.Spatially root channel zone was main force of wetland purification,and temporally the treatment effect was higher in low-temperature seasons indicating non-temperature dependent mechanisms worked.Water pollution comprehensive index improved steadily from IV to III,and comprehensive pollution load was reduced by ca.40%–60%.Comprehensive evaluation function value further showed the gradients purification effect of the upgraded wetland.Ecological wetlands ameliorated source water quality,and reduced drinking water treatment reagents,thereby bringing about economic benefits.Through wetlands operation,people can see how the micro-polluted surface water becomes clear and clean,so promoting a significant social benefit.As a viable component of urban green space,wetlands could beautify regional eco-environment,freshen the air,increase urban ecological taste,and enhance the eco-environmental protection publicity.Thus,the multifunctional service values and indirect benefits are substantial.Jiaxing ecological wetlands provide a typical paradigm for water pollution remediation in developing countries and plays a leading role in technology engineering radiation effect. | Weidong Wang Ting Yang Weibing Guan Weixi Peng Ping Wu Bin Zhong Chundong Zhou Qinghua Chen Rongbin Zhang Kewen Xu Chengqing Yin | 2021 | Journal of Environmental Sciences2021，33，12： | 1 |
