A review of atmospheric mercury emissions,pollution and control in China

Mercury, as a global pollutant, has significant impacts on the environment and human health. The current state of atmospheric mercury emissions, pollution and control in China is comprehensively reviewed in this paper. With about 500-800 t of anthropogenic mercury emissions, China contributes 25%-40% to the global mercury emissions. The dominant mercury emission sources in China are coal combustion, non-ferrous metal smelting, cement production and iron and steel production. The mercury emissions from natural sources in China are equivalent to the anthropogenic mercury emissions. The atmospheric mercury concentration in China is about 2-10 times the background level of North Hemisphere. The mercury deposition fluxes in remote areas in China are usually in the range of 10-50μg·m^-2·yr^-1. To reduce mercury emissions, legislations have been enacted for power plants, non-ferrous metal smelters and waste incinerators. Currently mercury contented in the flue gas is mainly removed through existing air pollution control devices for sulfur dioxide, nitrogen oxides, and particles. Dedicated mercury control technologies are required in the future to further mitigate the mercury emissions in China.     

Engineering application of membrane bioreactor for wastewater treatment in China: Current state and future prospect

China has been the forerunner of large-scale membrane bioreactor （MBR） application. Since the first large-scale MBR （≥ 10 000 m^3·d^-1） was put into operation in 2006, the engineering implementation of MBR in China has attained tremendous development. This paper outlines the commercial application of MBR since 2006 and provides a variety of engineering statistical data, covering the fields of municipal wastewater, industrial wastewater, and polluted surface water treatment. The total treatment capacity of MBRs reached 1× 10^6 m^3·d^-1 in 2010, and has currently exceeded 4.5 × 10^6 m^3·d^-1 with -75% of which pertaining to municipal wastewater treatment. The anaerobic/anoxic/aerobie-MBR and its derivative processes have been the most popular in the large-scale municipal application, with the process features and typical ranges of parameters also presented in this paper. For the treatment of various types of industrial wastewater, the configurations of the MBR-based processes are delineated with representative engineering cases. In view of the significance of the cost issue, statistics of capital and operating costs are also provided, including cost structure and energy composition. With continuous stimulation from the environmental stress, political propulsion, and market demand in China, the total treatment capacity is expected to reach 7.5 × 10^6 m^3·d^-1 by 2015 and a further expansion of the market is foreseeable in the next five years. However, MBR application is facing several challenges, such as the relatively high energy consumption. Judging MBR features and seeking suitable application areas should be of importance for the long-term development of this technology.     

A 14-year measurement of toxic elements in atmospheric particulates in Hong Kong from 1995 to 2008

Toxic elements in the atmosphere can enter and accumulate in the human body, seriously impacting human health. In this study, we analyzed a 14-year （1995-2008） measurement of three toxic elements （As, Cd and Cr） in PMlo in Hong Kong, China. The pollution of these toxic elements in Hong Kong was not serious. The trend analysis showed that As and Cr in PM10 increased at a statistically significant level （p〈0.05） during the 14-year period, while the Cd in PM10 did not change significantly. Typical seasonal variations were observed for all three toxic elements, largely in relation to the Asian monsoon. Hourly 10-day backward trajectories were computed and cate- gorised into four groups. The continental air masses showed much higher concentrations of the three toxic elements than the marine air masses. The abundances of As and Cd in the PM10 were much higher in the continental air masses than those in the marine air masses, while the abundances of Cr showed an opposite pattern. The trends of the three toxic elements in East China＇s air mass were consistent with those in the overall data set ofHong Kong. Examination of the toxic element data recorded at urban sites and a roadside site also indicated a large contribution of external air masses to particulate As and Cd in Hong Kong. These results suggest that the long-range transport from the mainland of China is the dominant contributor to particulate As and Cd, while both local and long-distance sources determine the particulate Cr in Hong Kong.     

Vanadium metabolism investigation using substance flow and scenario analysis

Vanadium is a vital strategic resource, and vanadium metabolism is an important part of the national socio-economic system of China. This study conducts accounting and scenario analysis on the life cycle of vanadium metabolism in China. Based on the character- istics of vanadium life cycle and substance flow analysis （SFA） framework, we present a quantitative evaluation of a static anthropogenic vanadium life cycle for the year 2010. Results show that anthropogenic vanadium consumption, stocks, and new domestic scrap are at 98.2, 21.2, and 4.1 kt, respectively; new scrap is usually discarded. The overall utilization ratio of vanadium is 32.2%. A large amount of vanadium is stockpiled into tailings, debris, slags, and other spent solids. A scenario analysis was conducted to analyze the future developmental trend of vanadium metabolism in China based on the SFA frame- work and the qualitative analysis of technology advance- ment and socio-economic development. The baseline year was set as 2010. Several indicators were proposed to simulate different scenarios from 2010 to 2030. The scenario analysis indicates that the next 20 years is a critical period for the vanadium industry in China. This paper discusses relevant policies that contribute to the improvement of sustainable vanadium utilization in China.     

Recovery of greenhouse gas as cleaner fossil fuel contributes to carbon neutrality

Under the context of carbon neutrality of China, it is urgent to shift our energy supply towards cleaner fuels as well as to reduce the greenhouse gas emission. Currently, coal is the main fossil fuel energy source of China. The country is striving hard to replace it with methane, a cleaner fossil fuel. Although China has rich geological resources of methane as coal bed methane(CBM) reserves, it is quite challenging to utilize them due to low concentration. The CBM is however mainly emitted dire...

Cleaning the energy sources for water heating among Nanjing households: barriers and opportunities for solar and natural gas

Energy for water heating accounts for an increasing part in residential energy demand in China. An extensive survey was conducted to analyze the determinants of household energy choices for water heaters among residents in Nanjing, China. Two sets of variables were examined as potential influences： building features and household socio-economic characteristics. Results suggest that building features such as gas availability and building structures, and household characteristics such as household head＇s education degree and energy-conserving sense are crucial determinants in choosing natural gas as water heater energy. Installation permission for solar water heater, building stories, and residential location serve as determining factors in choosing solar water heaters. Based on these, barriers and opportunities are discussed for transitions toward cleaner water heating energies, and suggestions are given for local governments to promote cleaner energy replacement in China.

全国两栖动物多样性观测网络(China BON-Amphibians)建设进展

两栖动物对环境变化反应敏感,是生物多样性观测的重要指示物种。近年来,欧美国家已制定了生物多样性观测相关标准并实施了一系列观测计划。2011年以来,环境保护部自然生态保护司以环境保护部南京环境科学研究所为牵头单位,联合全国相关科研院所、高等院校、保护机构,构建了全国两栖动物多样性网络,作为全国生物多样性观测网络(China BON)的重要组成部分。该研究介绍了我国两栖动物多样性观测方法,总结了2011年以来全国两栖动物多样性观测工作进展。据115个样区的观测结果显示,观测到的两栖动物共计243种,占我国两栖动物总种数的59.6%。通过观测,发现了破坏两栖动物生境的典型案例。目前我国两栖动物观测网络已初具规模,笔者在介绍观测网络现状的同时也提出了相关建议。

西北干旱区PM_(10)浓度特征及其与水平能见度的关系

利用环保部门的API、PM10数据和气象部门的能见度、相对湿度等相关数据,分析了2011─2013年西北干旱区(包括新疆、甘肃、内蒙古PM监测站点分别19个、5个、13个)PM10浓度的空间分布特征和时间变化特征,并以新疆为例,研究了其PM10浓度特征及其与水平能见度(包括全部天气条件和晴空条件,以及干能见度、干消光系数)的关系,以期了解西北干旱区的PM10浓度状况,为有效控制PM10污染提供科学依据。结果表明,(1)2011─2013年,整个西北干旱区的PM10浓度存在明显的区域差异,新疆的PM10浓度明显高于甘肃、内蒙古,且新疆和甘肃大部分城市的PM10浓度已超过国家二级质量标准。就季节分布而言,整个西北干旱区冬春季PM10浓度相对较高,秋季次之,夏季最低。(2)2011─2013年,西北干旱区绝大多数城市的PM10浓度月变化波动都比较大,波动曲线基本呈现出"M"型、"U"型、"N"型和"n"型4种。(3)PM10浓度与水平能见度呈负相关关系。为了降低分析误差,我们将PM10数值以100μg·m-3为步长进行了分组,分析了PM10浓度距平与水平能见度的关系,得出当PM10浓度为负距平时,能见度距平多为正值,且对应的水平能见度比相应气象条件下的平均值高,而当PM10浓度为正距平时,能见度距平多为负值,且对应的水平能见度比相应气象条件下的平均值低。
