| 1 | Health risks associated with heavy metals in the drinking water of Swat,northern Pakistan显示文摘The concentrations of heavy metals such as Cd, Cr, Cu, Mn, Ni, Pb and Zn were investigated in drinking water sources(surface and groundwater) collected from Swat valley, Khyber Pakhtunkhwa, Pakistan. The potential health risks of heavy metals to the local population and their possible source apportionment were also studied. Heavy metal concentrations were analysed using atomic absorption spectrometer and compared with permissible limits set by Pakistan Environmental Protection Agency and World Health Organization. The concentrations of Cd, Cr, Ni and Pb were higher than their respective permissible limits, while Cu, Mn and Zn concentrations were observed within their respective limits. Health risk indicators such as chronic daily intake(CDI) and health risk index(HRI) were calculated for adults and children separately. CDIs and HRIs of heavy metals were found in the order of Cr > Mn >Ni > Zn > Cd > Cu > Pb and Cd > Ni > Mn > Cr > Cu > Pb > Zn, respectively. HRIs of selected heavy metals in the drinking water were less than 1, indicating no health risk to the local people. Multivariate and univariate statistical analyses showed that geologic and anthropogenic activities were the possible sources of water contamination with heavy metals in the study area. | Kifayatullah Khan Yonglong Lu Hizbullah Khan Shahida Zakir Ihsanullah Sardar Khan Akbar Ali Khan Luo Wei Tieyu Wang | 2013 | Journal of Environmental Sciences2013，25，10： | 12 |
| 2 | Combined effects of cadmium and fluoranthene on germination, growth and photosynthesis of soybean seedlings显示文摘The single and combinational effects of cadmium (Cd) and fluoranthene (FLT) on germination, growth and photosynthesis of soybean seedlings were investigated. Exposure to 5, 10, or 15 mg Cd/L or 1, 5, or 10 mg FLT/L individually or in combination significantly decreased germination vigor (3 days) and final germination rate of soybean seeds, except at 1 and 5 mg FLT/L. The results of two-way ANOVA analysis and the Bliss independence model showed that at lower concentrations of FLT (1 mg/L), the interaction between Cd and FLT on germination was antagonistic, whereas the interaction was synergistic when the concentration of FLT was 5 or 10 mg/L and the concentration of Cd was 15 mg/L. Growth, expressed as dry weight, length of shoot and root, leaf area, and photosynthesis, expressed as net photosynthetic rate, intercellular CO2 concentration, chlorophyll contents and fluorescence of soybean seedlings were also reduced by exposure to 5 or 10 mg Cd/L or 1 or 5 mg FLT/L, singly or jointly. Significant antagonistic effects of exposure to 5 or 10 mg Cd/L or 1 or 5 mg FLT/L on shoot growth and photosynthesis were observed, whereas synergy and antagonism of Cd and FLT were both observed for root growth. | Qiushuang Li Yonglong Lu Yajuan Shi Tieyu Wang Kun Ni Li Xu Shijie Liu Lin Wang Qinli Xiong John.P Giesy | 2013 | Journal of Environmental Sciences2013，25，9： | 8 |
| 3 | Urban and rural transport of semivolatile organic compounds at regional scale: A multimedia model approach显示文摘Urban areas are generally regarded as major sources of some semivolatile organic compounds and other persistent organic pollutants(POPs) to the surrounding regions. Huge differences in contaminant emissions between urban and rural areas directly affect their fate in environmental media. Little is known about POPs behavior between urban and rural areas at a regional scale. A spatially resolved Berkeley-Trent-Urban-Rural Fate Model(BETR-UR) was designed by coupling land cover information to simulate the transport of POPs between urban and rural areas, and the Bohai Rim was used as a case study to estimate Polycyclic Aromatic Hydrocarbon(PAH) fate. The processes of contaminant fate including emission, inter-compartmental transfer, advection and degradation in urban and rural areas were simulated in the model. Simulated PAH concentrations in environmental media of urban and rural areas were very close to measured values. The model accuracy was highly improved, with the average absolute relative error for PAH concentrations reduced from 37% to 3% compared with unimproved model results. PAH concentrations in urban soil and air were considerably higher than those in rural areas. Sensitivity analysis showed temperature was the most influential parameter for Phen rather than for Bap, whose fate was more influenced by emission rate, compartment dimension, transport velocity and chemical persistence. Uncertainty analysis indicated modeled results in urban media had higher uncertainty than those in rural areas due to larger variations of emissions in urban areas. The differences in urban and rural areas provided us with valuable guidance on policy setting for urban–rural POP control. | Shuai Song Chao Su Yonglong Lu Tieyu Wang Yueqing Zhang Shijie Liu | 2016 | Journal of Environmental Sciences2016，28，1： | 5 |
| 4 | Perfluoroalkyl substances and organochlorine pesticides in sediments from Huaihe watershed in China显示文摘Twelve perfluoroalkyl substances(PFASs) and nine organochlorine pesticides(OCPs) were quantified in surface sediments from the Huaihe River, China, along which there are intensive industrial and agricultural activities. Concentrations of PFASs ranged from 0.06 to 0.46 ng/g dry weight(dw), and concentrations of OCPs ranged from 1.48 to 32.65 ng/g dw. Compared with other areas in China, concentrations of PFASs were lesser than the national mean value, while concentrations of OCPs were moderate. Concentrations of perfluorooctanoic acid(PFOA) and perfluorooctane sulfonate(PFOS) ranged from n.d.(not detected) to 0.03 and n.d. to 0.10 ng/g dw,respectively. Among the three groups of OCPs, mean concentrations of hexachlorocyclohexane and its isomers(HCHs), dichlorodiphenyltrichloroethane and its metabolites(DDTs) and hexachlorobenzene(HCB) were 5.62 ± 4.35, 2.43 ± 3.12 and 1.55 ± 4.17 ng/g dw, respectively.Concentrations of HCHs and DDTs decreased from upstream to downstream along the mainstream of the Huaihe River. When compared to sediment quality guidelines(SQGs),concentrations of HCHs, DDTs and HCB would pose adverse biological effects. In general,contamination by PFASs in the upstream of the Huaihe River was more severe than that in the downstream, which was mainly caused by interception from dams, locks and industrial emissions. And OCPs from tributaries, especially the Yinghe River and Wohe River, were higher than those from Huaihe mainstream, and primarily came from historical inputs. | Jing Meng Tieyu Wang Pei Wang John P.Giesy Yonglong Lu | 2014 | Journal of Environmental Sciences2014，26，11： | 5 |
| 5 | Factors influencing the contents of metals and As in soils around the watershed of Guanting Reservoir,China显示文摘Topsoil samples from 61 sites around the Guanting Reservoir,China,were measured for Cu,Zn,Cr,Ni,Cd,Pb and As concentrations.The mean concentrations of Cu,Zn,Cr,Ni,Cd,Pb and As were 16.8,59.4,37.8,18.3,0.32,20.1 and 8.67 mg/kg dry weight,respectively.Factors that influence the dynamics of these metals in soils around the watersheds of Beijing reservoirs were examined.The influence of atmospheric deposition,land use,soil texture,soil type and soil chemical parameters on metal contents in soils was investigated.Atmospheric deposition,land use and soil texture were the important factors affecting heavy metal residues.Soil type and soil chemical parameters were also involved in heavy metal retention in soils.The data provided in this study are considered crucial for reservoir remediation,especially since the Guanting Reservoir will serve as one of the main drinking water sources for Beijing in the foreseeable future. | Li Xu Tieyu Wang Wei Luo Kun Ni Shijie Liu Lin Wang Qiushuang Li Yonglong Lu | 2013 | Journal of Environmental Sciences2013，25，3： | 4 |
| 6 | Climate change induced eutrophication of cold-water lake in an ecologically fragile nature reserve显示文摘Aquatic ecosystem sustainability around the globe is facing crucial challenges because of increasing anthropogenic and natural disturbances. In this study, the Tianchi Lake, a typical cold-water lake and a UNESCO/MAB(Man and Biosphere) nature reserve located in high latitude and elevation with the relatively low intensity of human activity was chosen as a system to examine the linkages between climate change and eutrophication. As a part of the UNESCO Bogda Man and Biosphere Reserve, Tianchi Lake has been well preserved for prevention from human intervention, but why has it been infected with eutrophication recent years? Our results show that climate change played a significant role in the eutrophication in the Tianchi Lake. Increased temperature, changed precipitation pattern and wind-induced hydrodynamic fluctuations in the summer season were suggested to make a major contribution to the accelerated eutrophication. The results also showed that the local temperature and precipitation changes were closely linked to the large-scale atmospheric circulation, which opens the door for the method to be applied in other regions without local climatic information. This study suggests that there is an urgent need to take into consideration of climate change adaptation into the conservation and management of cold-water lakes globally. | Xiaotian Lu Yonglong Lu Deliang Chen Chao Su Shuai Song Tieyu Wang Hanqin Tian Ruoyu Liang Meng Zhang Kifayatullah Khan | 2019 | Journal of Environmental Sciences2019，31，1： | 4 |
| 7 | Environmental pollution by persistent toxic substances and health risk in an industrial area of China显示文摘Soil is an important environmental medium that is closely associated with humans and their health.Despite this,very few studies have measured toxicants in soils,and associated them with health risks in humans.An assessment of health effects from exposure to contaminants in soils surrounding industrial areas of chemical production and storage is important.This article aims at determining pollution characteristics of persistent toxic substances (PTS) in an industrial area in China to unravel the relationship between soil pollution by PTS and human health.One hundred and five soil samples were collected and 742 questionnaires were handed out to residents living in and around an industrial area around Bohai Bay,Tianjin in Northern China.Concentrations of organochlorine pesticides and polycyclic aromatic hydrocarbons (PAHs) were determined in soil.Mann-Whitney U and binary multivariate non-conditional logistic regression models were employed to analyze the relationship between health indicators of local residents and contaminant levels.Odds ratio (OR) and a 95% confidence interval (CI) for health incidences were also calculated.The average concentrations of DDT (73.9 ng/g),HCH (654 ng/g) and PAHs (1225 ng/g) were relatively high in the industrial area.Residents living in the chemical industry parks were exposed to a higher levels of PTS than those living outside the chemical industry parks.This exposure was associated with a higher risk of breast cancer (OR 1.87,95% CI 0.12-30.06),stomach cancer (OR 1.87,95% CI 0.26-13.41),dermatitis (OR 1.72,95% CI 1.05-2.80),gastroenteritis (OR 1.59,95% CI 0.94-2.68),and pneumonia (OR 1.05,95% CI 0.58-1.89). | Jing Li Yonglong Lu Yajuan Shi Tieyu Wang Guang Wang Wei Luo Wentao Jiao Chunli Chen Feng Yan | 2011 | Journal of Environmental Sciences2011，23，8： | 3 |
| 8 | Factors influencing polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran (PCDD/F) emissions and control in major industrial sectors: Case evidence from Shandong Province, China显示文摘Analyzing determinants that influence polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran(PCDD/F) emissions is helpful for decision-makers to find effective and efficient ways to mitigate PCDD/F emissions. The PCDD/F emissions and the contributions of the scale effect, structure effect and technology effect to emissions from eight main industrial sectors in2006, 2008 and 2010 in Shandong Province, were calculated in this article. Total PCDD/F emissions in Shandong increased by 52.8% in 2008(614.1 g I-TEQ) and 49.7% in 2010(601.8 g I-TEQ) based on 2006(401.9 g I-TEQ). According to the decomposition method, the largest influencing factor on PCDD/F emission changes was the composition effect(contributed 43.4%in 2008 and 120.6% in 2010 based on 2006), which was also an emission-increasing factor.In this case, the present industrial restructuring policy should be adjusted to control the proportion of production capacities with high emission factors, such as iron ore sintering and steelmaking and the secondary non-ferrous metal sector. The scale effect increased the emissions in 2008(contributed 21.9%) and decreased the emissions in 2010(contributed-28.0%). However, as a source control measure, the excess capacity control policy indeed had a significant role in emission reduction. The main reason for the technology effect(contributed 34.7% in 2008 and 7.4% in 2010 based on 2006) having an emission-increasing role was the weakness in implementing policies for restricting industries with outdated facilities. Some specific suggestions were proposed on PCDD/F reduction for local administrators at the end. | Lin Wang Yonglong Lu Guizhen He Arthur P.J.Mol Tieyu Wang Jorrit Gosens Kun Ni | 2014 | Journal of Environmental Sciences2014，26，7： | 2 |

| 14 | Multi-factors influencing the spatial distribution of polycyclic aromatic hydrocarbons in soils surrounding drinking water protection zone显示文摘We selected the Guanting Reservoir in Beijing, China as a case where an industrial area locates on the upwind corner to study the influence of human activities and natural processes on the distribution of polycyclic aromatic hydrocarbons (PAHs) in soils. Soil PAH concentrations in the study area follow a log-normal probability distribution function, suggesting that distribution of PAH in soils was affected by human activities. Distribution of PAHs in soils was significantly affected by the point source that high PAH concentrations were observed in near industrial area with an obvious declining trend from the northwest to the southeast which was the prevailing wind direction in this area. Away from the influence of point source, distribution of PAHs in soils was found to significantly correlate with total organic carbon content, while the influences of agricultural land uses and type of soil texture on the total soil PAHs contents and ring compositions were quite limited. The results can provide some evidences and data on the pollutant accumulation in drink water protection area influenced by natural processes and human activities. | Wentao Jiao Tieyu Wang Yonglong Lu Andrew Chang Weiping Chen | 2013 | Journal of Environmental Sciences2013，25，8： | 1 |
