| 1 | 特种污染物排放源强反演及可视化分析工具研发及Hg^2+分析示例显示文摘研发了特种污染物排放源强反演及可视化分析工具,集成利用了WRF气象预报结果及HYSPLIT前向轨迹规划外场监测点,调用CALPUFF模型基于监测数据和对应气象条件快速反算源强并模拟得到排放影响范围,并使用开源GIS平台进行可视化分析.同时,选取大气背景浓度极低的活性气态汞(Hg^(2+))为目标,以李坑垃圾焚烧厂不稳定Hg^(2+)排放为监测主体.结果表明,基于下风向监测数据反演的源强与实测的烟气Hg^(2+)含量有着较好的一致性(R^2=0.801).该工具可作为特种大气污染事故应急辅助决策新手段,提供包含非稳态排放源强、污染扩散影响范围等信息在内的关键依据. | 危浩 朱云 许嘉钰 余斌 王书肖 付学吾 Lin Chejen 张磊 杨文尉 杨再东 | 2017 | 环境科学学报2017，37，2： | 3 |
| 2 | Decreasing mercury levels in consumer fish over the three decades of increasing mercury emissions in China显示文摘Fish consumption is the primary dietary route of human exposure to methylmercury.It has been well documented that elevated mercury concentration in fish in North America and Europe is linked to anthropogenic mercury emissions.China is the world’s largest producer,consumer,and emitter of mercury,as well as the world’s largest commercial fish producer and consumer.Although mercury pollution in fish in China is currently receiving much attention worldwide,its status remains largely unknown.Here,we conducted a meta-analysis on total mercury concentrations in marine and freshwater fish samples,covering 35,464 samples collected in China over the past 30 years.It is found that,opposite to the increasing emission and documented mercury contamination events,mercury levels in fish have gradually decreased in China over the past 30 years.The results were in sharp contrast to those found in North America and Europe.The mercury concentrations in fish were significantly anticorrelated with the fish catch and fish aquaculture and were inverse to trophic levels.Overfishing and the short lifecycle of aquaculture fish,both reducing the trophic level and the duration of mercury accumulation,were the most likely causes leading to the decline of mercury concentrations found in fish in China. | Hua Zhang Wenxiong Wang Chejen Lin Xinbin Feng Jianbo Shi Guibin Jiang Thorjørn Larssen | 2022 | Eco-Environment & Health2022，1，1： | 2 |
