Concentrations of anthropogenic Pt and Pd in urban roadside soils in Xuzhou, China

WANG Xuesong, SUN Cheng

《环境科学与工程前沿(英文)》 2008年 第2卷 第4期   页码 475-479 doi: 10.1007/s11783-008-0071-3

摘要: The potential accumulation of platinum group elements (PGE) in the environment from automobile catalysts is high in urban areas, with the major sinks being roadside soils. Therefore, this investigation presented the detailed study on characterized concentrations of Pt and Pd and their enrichment ratios in urban roadside soils in Xuzhou, China in March 2003. Data from 21 roadside topsoil samples analyzed by inductively coupled plasma-mass spectrometer (ICP-MS) illustrated that the medians of concentrations of Pt and Pd were 2.9 and 2.8 ng/g, respectively. Hierarchical clustering analysis indicated that Pt and Pd were mainly from traffic emissions. Compared to unpolluted soils, computation of Pt and Pd enrichment ratios suggested that the Xuzhou roadside soils had average enrichment factors of 3.53 for Pt (in range of 1.22–5.73) and of 3.37 for Pd (in range of 1.35–4.46). Lower Pt/Pd ratios (in range of 0.35–2.86) in relation to similar studies in other countries were observed, which might be due to the different Pt/Pd ratios in Chinese automobile catalytic converters. Moreover, fine fraction (<250 ?m) contained higher concentrations of Pt and Pd compared to the coarse fraction (250–500 ?m).

Chemical speciation and anthropogenic sources of ambient volatile organic compounds (VOCs) during summer

LU Sihua, LIU Ying, SHAO Min, HUANG Shan

《环境科学与工程前沿(英文)》 2007年 第1卷 第2期   页码 147-152 doi: 10.1007/s11783-007-0026-0

摘要: Volatile organic compounds (VOCs) were measured at six sites in Beijing in August, 2004. Up to 148 VOC species, including C to C alkanes, C to C alkenes, C to C aromatics, and halogenated hydrocarbons, were quantified. Although the concentrations differed at the sites, the chemical compositions were similar, except for the Tongzhou site where aromatics were significantly high in the air. Based on the source profiles measured from previous studies, the source apportionment of ambient VOCs was preformed by deploying the chemical mass balance (CMB) model. The results show that urban VOCs are predominant from mobile source emissions, which contribute more than 50% of the VOCs (in mass concentrations) to ambient air at most sites. Other important sources are gasoline evaporation, painting, and solvents. The exception is at the Tongzhou site where vehicle exhaust, painting, and solvents have about equal contribution, around 35% of the ambient VOC concentration. As the receptor model is not valid for deriving the sources of reactive species, such as isoprene and 1,3-butadiene, other methodologies need to be further explored.

Trends of chemical speciation profiles of anthropogenic volatile organic compounds emissions in China

Wei WEI, Shuxiao WANG, Jiming HAO, Shuiyuan CHENG

《环境科学与工程前沿(英文)》 2014年 第8卷 第1期   页码 27-41 doi: 10.1007/s11783-012-0461-4

摘要: This study estimates the detailed chemical profiles of China’s anthropogenic volatile organic compounds (VOCs) emissions for the period of 2005–2020. The chemical profiles of VOCs for seven activity sectors are calculated, based on which the Photochemical Ozone Creation Potential (POCP) of VOCs for these sectors is evaluated. At the national level, the VOCs species emitted in 2005 include alkanes, alkenes and alkynes, aromatic compounds, alcohols, ketones, aldehydes, esters, ethers and halocarbons, accounting for 26.4 wt.%, 29.2 wt.%, 21.3 wt.%, 4.7 wt.%, 5.4 wt.%, 1.7 wt.%, 2.1 wt.%, 0.7 wt.% and 2.2 wt.% of total emissions, respectively. And during 2005-2020, their mass proportions would respectively grow or decrease by -6.9%, -32.7%, 7.3%, 65.3%, 34.7%, -48.6%, 108.5%, 100.5%, and 55.4%. This change would bring about a 13% reduction of POCP for national VOCs emissions in the future. Thus, although the national VOCs emissions are expected to increase by 33% over the whole period, its ozone formation potential is estimated to rise only by 14%. Large discrepancies are found in VOCs speciation emissions among provinces. Compared to western provinces, the eastern provinces with a more developed economy would emit unsaturated hydrocarbons and benzene with lower mix ratios, and aromatic compounds except benzene, oxidized hydrocarbons and halocarbons with higher mix ratios. Such differences lead to lower POCP of VOCs emitted in eastern provinces, and higher POCP of VOCs emitted in western provinces. However, due to the large VOCs emissions from Chinese eastern region, the ozone formation potential of VOCs emission in eastern provinces would be much higher than those in western provinces by about 156%–235%.

Air pollution affects food security in China: taking ozone as an example

Zhaozhong FENG,Xuejun LIU,Fusuo ZHANG

《农业科学与工程前沿(英文)》 2015年 第2卷 第2期   页码 152-158 doi: 10.15302/J-FASE-2015067

摘要: Air pollution is becoming an increasingly important environmental concern due to its visible negative impact on human health. However, air pollution also affects agricultural crops or food security directly or indirectly, which has not so far received sufficient attention. In this overview, we take ozone (O ) as an example to analyze the principles and extent of the impact of air pollution on food security in China based on a review of the literature. Current O pollution shows a clear negative impact on food security, causing around a 10% yield decrease for major cereal crops according to a large number of field studies around the world. The mean yield decrease of winter wheat is predicted to be up to 20% in China, based on the projection of future ground-level O concentration in 2020, if no pollution control measures are implemented. Strict mitigation of NO and VOC (two major precursors of O ) emissions is crucial for reducing the negative impacts of ground-level O on food security. Breeding new crop cultivars with tolerance to high ground-level O should receive serious consideration in future research programs. In addition, integrated soil-crop system management will be an important option to mitigate the negative effects of elevated ground-level O on cereal crop production and food quality.

摘要: CO2 is one of the most important greenhouse gases (GHGs) in the earth’s atmosphere. Since the industrial era, anthropogenic activities have emitted excessive quantities of GHGs into the atmosphere, resulting in climate warming since the 1950s and leading to an increased frequency of extreme weather and climate events. In 2020, China committed to striving for carbon neutrality by 2060. This commitment and China’s consequent actions will result in significant changes in global and regional anthropogenic carbon emissions and therefore require timely, comprehensive, and objective monitoring and verification support (MVS) systems. The MVS approach relies on the top-down assimilation and inversion of atmospheric CO2 concentrations, as recommended by the Intergovernmental Panel on Climate Change (IPCC) Inventory Guidelines in 2019. However, the regional high-resolution assimilation and inversion method is still in its initial stage of development. Here, we have constructed an inverse system for carbon sources and sinks at the kilometer level by coupling proper orthogonal decomposition (POD) with four-dimensional variational (4DVar) data assimilation based on the weather research and forecasting–greenhouse gas (WRF–GHG) model. Our China Carbon Monitoring and Verification Support at the Regional level (CCMVS-R) system can continuously assimilate information on atmospheric CO2 and other related information and realize the inversion of regional and local anthropogenic carbon emissions and natural terrestrial ecosystem carbon exchange. Atmospheric CO2 data were collected from six ground-based monitoring sites in Shanxi to verify the inversion effect of regional anthropogenic carbon emissions by setting ideal and real experiments using a two-layer nesting method (at 27 km and 9 km). The uncertainty of the simulated atmospheric CO2 decreased significantly, with a root-mean-square error of CO2 concentration values between the ideal value and the simulated after assimilation was close to 0. The total anthropogenic carbon emissions in Shanxi Province in 2019 from the assimilated inversions were approximately 28.6% (17%–38%) higher than the mean of five emission inventories using the bottom-up method, showing that the top-down CCMVS-R system can obtain more comprehensive information on anthropogenic carbon emissions.

摘要:

汞(Hg)及其衍生物作为危险的环境污染物,其生物毒性、生物累积和放大作用对水生生态系统和人类健康造成潜在风险。沉积物柱芯可为湖泊历史污染过程提供重要信息,追溯人类活动或自然条件变化的影响。本研究以浅水富营养化湖泊——巢湖为例,解析巢湖沉积物中汞的百年历史变化及其受人类活动和气候变化的影响。结果表明,巢湖汞的沉积经历了3个阶段(20世纪60年代前、20世纪60—80年代和20世纪80年代后)。20世纪60年代前,沉积物柱芯汞含量的变化趋势不显著,且东、西湖区无空间差异;20世纪60—80年代,沉积物汞的浓度逐渐升高,西湖区的汞浓度高于东湖区,主要与西湖区受人为污染较重有关;通过分析沉积物汞与重金属(铁、钴、铬、铜、锰、铅、锌)、碳氮稳定同位素(δ13C 和 δ15N)、营养物质、粒度和气象因子的关系,揭示了人类活动、水动力条件和气候变化对巢湖汞沉积的影响,发现20 世纪60年代以后沉积物剖面的汞浓度明显升高,主要是由于水动力条件变化和流域经济快速发展导致了人为源汞输入的增长。此外,温度、风速和蒸发量对汞的环境行为和归趋产生交互复杂影响。

摘要:
气候变化导致海平面上升是河口三角洲城市发展面临的主要威胁,位处长江河口三角洲的特大型城市上海面临同样的问题。就气候变化适应性决策者而言,其困难在于海平面上升的原因、幅度和出现时间的不确定性。本文在年代际尺度上就海平面上升原因、幅度的甄别做了尝试。即在分析上海沿岸11 个潮位站1921 年以来潮位记录及其相邻水域水下地形基础上,发现该地区海平面上升除了众所周知的理论海平面上升、构造沉降和城市地面沉降外,还有三种新的、人为地形改变所致的海平面上升行为。其一为围垦和深水航道整治导致的局域海平面上升;其二是流域沉积物源减少引起河槽冲刷导致的局域海平面下降;其三为局域深度基准面抬升。上海沿岸2011—2030年间海平面上升幅度预测值为10~16 cm。这一海平面上升行为的甄别结果为当地决策者制定河口三角洲系统适应气候变化和海平面上升的工程和非工程措施提供科学依据,以期减少日益加剧的洪灾损失。此项工作未来充满挑战。
