Pollution survey of carbonyl compounds in train air

The train is an important vehicle in China, but its air quality has important impacts on passengers’ health. In this work, pollution from carbonyl compounds was measured in the air of six trains. The objectives of this work were to investigate carbonyl compound levels in selected air from trains, identify their emission sources, and assess the intake of carbonyl compounds for passengers. The methods for sampling and analyzing 10 carbonyl compounds such as formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, butyraldehyde, benzaldehyde, cyclohexanone, and valeraldehyde in indoor air were proposed with the sampling efficiency, recovery, and detection limit being 92%–100%, 91%–104%, and 0.26–0.82 ng/m³, respectively. It was indicated that the total concentrations of carbonyl compounds were 0.159–0.2828 mg/m³ with the average concentration of 0.2330 mg/m³. The average concentrations of form aldehyde, acetaldehyde and acetone were 0.0922, 0.0499, and 0.0580 mg/m³, accounting for 42.6%, 21.4%, and 24.9% of the total concentrations of carbonyl compounds, respectively. The carbonyl compounds probably came from woodwork and cigarette smoking. The intake of carbonyl compounds for the passengers was approximately 0.043–0.076 mg/h. The carbonyl compounds in train air could be harmful to human health. Translated from Environmental Science, 2006, 27(1) 91–94 [译自: 环境科学]     

Transboundary air pollution balance in the new integrated European environment

Ten out of the 12 new EU members, used to belong to the so-called “former eastern block”, with a post WWII environmental policy radically different from the tendencies followed in Western Europe. The lack of conservation regulations has resulted in a rather harmful industrialization, regarding natural resources and environmental quality. While air pollution transfer is a phenomenon of transboundary level, there is a particular interest in examining the contribution of the new EU member states to the environmental pressure faced by the older member states and vice versa. The current study utilises the official data for almost 20 years published by the European Monitoring and Evaluation Program concerning the transboundary transfer of NO_x and SO₂ in order to analyse the situation and discuss the present and future environmental policy regarding air pollution.     

呼和浩特市不同粒径空气颗粒物中汞的分布规律

采用分级采样装置 ,于冬夏两季采集呼市三个不同功能区不同粒径空气颗粒物中的汞进行分析 ,结果表明 :呼市空气颗粒物中的汞含量冬季明显高于夏季 ;冬季空气颗粒物中的汞含量为居民区 >交通区 >对照区 ,夏季为交通区 >居民区 >对照区 ;空气中汞主要富集在可吸入粒子中。     

滇池流域农田氮、磷肥施用现状与评价

2001年6月至9月分别对流域内晋宁，呈贡，西山，官渡和嵩明调查了365家农户有关化肥施用情况，调查分析和计算表明，每年从种植业流失的化肥中纯氮（N）达2575t，纯磷（P）达218t，蔬菜和花卉地的单位面积氮流失量是水田和旱地的7-20倍。菜地年每公顷流失氮204kg，水田的氮流失量最低，平均每公顷每年流失10kg。磷的流失也以蔬菜，花卉地为最高，蔬菜和花卉地的单位面积磷流失量是水田和旱地的9-10倍。研究结果证明，大量的氮，磷化肥施用，通过地表径流和地下水流入滇池是造成其水体富营养化的重要原因之一^[6]，随着农业和农村经济的发展，蔬菜，花卉等经济作物在滇池流域的种植面积将会逐年扩大，因氮，磷化肥的施用面造成的氮，磷流失量将会不断加大，为了实现减少氮，磷化肥对滇池的污染，应积极推广精确施肥，平衡施肥等科学施肥技术，提高化肥利用率，减少化肥流失。增施有机肥，降低化肥用量，同时提高农村居民的环境意识，加强环境管理，依法保护农村环境，控制农业面源污染。
