CONCENTRATIONS AND FLUXES OF DISSOLVED NUTRIENTS IN THE YANGTZE RIVER: LONG-TERM TRENDS AND ECOLOGICAL

《农业科学与工程前沿（英文）》 2021年 第8卷 第4期   页码 559-567 doi: 10.15302/J-FASE -2020344

摘要：

Intensifying human activity in the Yangtze River basin has substantially increased nutrient concentrations in the Yangtze River Estuary, leading to degradation of the coastal environment. Analysis of nutrient determinations published over the past 50 years reveals a gradual decreasing trend in the concentrations and fluxes of dissolved silicate (DSi). However, both dissolved inorganic nitrogen (DIN) and dissolved inorganic phosphate (DIP) concentrations have increased significantly since the 1970s. The frequency of and area covered by red tide outbreaks have increased greatly during this period, mainly due to changes in nutrient supply ratios [i.e., N/P (DIN/DIP), N/Si (DIN/DSi), P/Si (DIP/DSi)]. A strong correlation was found between the riverine DIN fluxes and the estimated DIN inputs from the major N sources, particularly fertilizers and atmospheric deposition. The data provide a comprehensive assessment of nutrients in the Yangtze River basin and their ecological impacts and indicate a potentially significant influence of atmospheric deposition on DIN loadings and fluxes.

《中国工程科学》 2022年 第24卷 第5期   页码 19-25 doi: 10.15302/J-SSCAE-2022.05.003

摘要：

饮用水安全关系国计民生，我国政府一直高度重视饮用水安全保障工作。改革开放以来，在经济发展活跃、人口高度密集的长三角地区，水体环境污染给饮用水安全保障带来了巨大挑战；经过十余年的发展，长三角饮用水安全保障水平整体显著提升，有力促进了区域协调可持续发展，然而人民群众对水质安全和健康的要求也在逐渐提高，长三角超大城市群饮用水安全保障工作依然面临诸多挑战。由此，本文以长三角典型水源水质特征为切入点，总结了城市饮用水安全保障工作实施成效，从管理和技术两个维度，以及水源、水厂、管网（二次供水）三个方面剖析了饮用水水质进一步提升的现状问题，提出了健全生态补偿机制、协同修订水质标准、发展绿色高效净化技术、创新供水管理模式等措施建议，以期为长三角超大城市群和其他重点区域的饮用水安全保障和区域一体化发展提供参考与借鉴。

摘要：

长江三角洲地区（简称长三角地区）是我国重要的工农业生产基地，关注该地区农用地土壤重金属污染状况对促进地区经济社会良性发展、保障生态环境安全具有重要意义。本文根据近 20 年发表的长三角地区农用地土壤重金属相关文献中的重金属含量数据，全面分析长三角不同区域农用地土壤典型重金属累积情况与污染状况，系统探究导致长三角地区农用地土壤重金属累积与污染的主要原因。分析发现，工业“三废”排放、交通运输、化肥、农药、农膜等的大量施用（使用），使得长三角地区农用地土壤中重金属 Cd 累积与污染情况最为严重，其次是 Cu、 Hg 和 Pb，而浙江台州和安徽铜陵分别存在Cd、 Hg 和 Cu， Cd、 Pb 和 Cu 多种重金属复合污染问题。针对长三角地区农用地土壤重金属污染防治的迫切需求和主要污染成因，在农用地土壤重金属污染源头控制、农用地土壤重金属快速动态监测、农用地土壤分级管理、重金属污染农用地土壤修复新技术研发、农用地土壤污染防治立法等方面提出了相关防治建议，以期为改善长三角地区农用地土壤生态环境、促进优质高效农业的可持续发展提供参考。

《环境科学与工程前沿（英文）》 2016年 第10卷 第1期   页码 53-62 doi: 10.1007/s11783-014-0728-z

摘要： Understanding the trends in PM levels is essential for formulating clean air plans. This paper analyzes PM data from various published sources for the years 2000 to 2010 in the Pearl River Delta Economic Zone (PRDEZ). The long-term variation in PM mass concentration is analyzed. Results show that PM , organic carbon (OC), elemental carbon (EC), and show a similar trend, increasing before 2005 and then decreasing slightly. The annual average PM concentration ranges from 49.1 μg·m in 2000 to 64.3 μg·m in 2010, with a peak of 84.1 μg·m in 2004. None of these 11 years meets the new National Ambient Air Quality standard (NAAQS) for PM (35 μg·m ). Overall average concentrations of OC, EC, and are 13.0, 6.5, and 11.8 μg·m , respectively. and respectively have concentrations of 1.5 μg·m and 2.9 μg·m in 2000 and 6.4 μg·m and 5.3 μg·m in 2010, with a statistically significant average annual trend of+ 0.2 μg·m ·yr and+ 0.1 μg·m ·yr . In certain geographic regions, OC and EC contribute most of the PM , while in other regions secondary water-soluble ions are more important. In general, OC and are the dominant components of PM , contributing 20.6% and 18.6%, respectively. These results provide, for the first time, a better understanding of the long-term PM characteristics and trends, on a species-by-species basis, in the PRDEZ. The results indicate that PM abatement needs to prioritize secondary species.

Estimated anthropogenic Hg emission was 11.9 tons in Pearl River Delta for 2014.

Quantifying contributions of emission sources helps to provide control strategies.

More attentions should be paid to Hg deposition around the large point sources.

Power plant, industrial source and waste incinerator were priorities for control.

A coordinated regional Hg emission control was important for controlling pollution.

摘要： Spatial and temporal trends of the typical pollutants in PRD viewed from space. Comparisons of the satellite retrievals with the collocated in situ data are given. Among different MCs, the control measures applied in PRD are the most effective. The unique HCHO trends imply significant contribution from the biogenic origins. The Pearl River Delta (PRD) is one of the most industrialized, urbanized and populated regions in China, and thus has been long suffering from severe air pollutions. Space data provide a unique perspective for investigating the atmospheric environment at a regional scale. By utilizing multiple satellite retrievals from 2005 to 2013, this study presented, for the first time, the spatial patterns and temporal trends of typical air pollutants over PRD and its vicinity. As viewed from space, aerosol optical depth (AOD), NO2 and SO2 all had their higher values at the central part of PRD, and showed clear descending gradients as moving to the outskirt of this region. As to the inter-annual variation, all these pollutants had decreasing trends in PRD during the study period, which generally agreed with the relevant in situ measurements. However, the satellite retrievals differed from ground measurements when addressing NO2 and SO2 in the vicinity of PRD. This work also provides the inter-comparison among PRD and three other metropolitan clusters in China: PRD had relatively high AOD, moderate NO2 and low SO2 levels, and it was the only region achieving the effective reduction of NO2 and SO2 during last decade. Unlike the previous three pollutants, HCHO observed by satellite showed very special patterns: it had a relatively homogeneous spatial distribution over both of PRD and its vicinity, and presented an opposite increasing trend from 2005 to 2010. Moreover, PRD had the highest HCHO level among all the metropolitan clusters, hinting a considerable contribution of biogenic origins of HCHO in PRD.

Photochemical indicators of ozone sensitivity: application in the Pearl River Delta, China

《环境科学与工程前沿（英文）》 2016年 第10卷 第6期 doi: 10.1007/s11783-016-0887-1

摘要： The distribution of NO - and VOC-sensitive regimes in the PRD are identified. The effectiveness of six popular chemical indicators for discriminating O sensitivity regimes is evaluated. Threshold levels for HCHO/NO , H O /HNO , O /NO , O /NO , O /HNO were derived and verified. The indicators H O /HNO and H O /NO performed best and maintained relatively stable threshold levels. Surface O production has a highly nonlinear relationship with its precursors. The spatial and temporal heterogeneity of O -NO -VOC-sensitivity regimes complicates the control- decision making. In this paper, the indicator method was used to establish the relationship between O sensitivity and assessment indicators. Six popular ratios indicating ozone-precursor sensitivity, HCHO/NO , H O /HNO , O /NO , O /NO , O /HNO , and H O /NO , were evaluated based on the distribution of NO - and VOC-sensitive regimes. WRF-Chem was used to study a serious ozone episode in fall over the Pearl River Delta (PRD). It was found that the south-west of the PRD is characterized by a VOC-sensitive regime, while its north-east is NO -sensitive, with a sharp transition area between the two regimes. All indicators produced good representations of the elevated ozone hours in the episode on 6 November 2009, with H O /HNO being the best indicator. The threshold sensitivity levels for HCHO/NO , H O /HNO , O /NO , O /NO , O /HNO , and H O /NO were estimated to be 0.41, 0.55, 10.2, 14.0, 19.1, and 0.38, respectively. Threshold intervals for the indicators H O /HNO , O /NO , O /NO , O /HNO , and H O /NO were able to identify more than 95% of VOC- and NO -sensitive grids. The ozone episode on 16 November 16 2008 was used to independently verify the results, and it was found that only H O /HNO and H O /NO were able to differentiate the ozone sensitivity regime well. Hence, these two ratios are suggested as the most appropriate indicators for identifying fall ozone sensitivity in the PRD. Since the species used for indicators have seasonal variation, the utility of those indicators for other seasons should be investigated in the future work.
