Analysing Air Pollution Exposure in London

<p>Updated in Februrary 2017.</p>
<p>Air quality in London has improved in recent years as a result of policies to reduce emissions, primarily from road transport. However, recently updated maps of pollution concentrations for 2013 (LAEI 2013) still show significant areas of exceedances of the annual mean NO2 EU Limit Values. Improvements are planned to address these, as recently announced in the Mayor&rsquo;s package of air quality measures.</p>

<li>The <a href="/dataset/analysing-air-pollution-exposure-in-london/resource/0925e909-9e44-4de3-ae72-97497d3c8511">Updated Analysis of Air Pollution Exposure in London</a> research provides an update to similar analysis undertaken in 2013 (which looked at pollution exposure in 2010), published recently by City Hall. It examines pollution exposure in London in 2013 and considers how exposure varies by indicators of age, relative deprivation and ethnic groups in London. It also looks at total exposure (broken down by borough) and exposure at schools. <br /> <br /> Through the research described in this report, City Hall is seeking to understand the inequalities in accessing clean air in London and considering how this will be improved by planned air pollution policies.<br /><br /></li>
<li>The spreadsheet lists the schools located in areas where average concentrations of Nitrogen Dioxide (NO2) are over the legal and safe limit as defined by the EU Limit Values; the Limit Value is 40 &mu;g/m3. The modelled NO2 data used in this report is from the 2013 London Atmospheric Emissions Inventory (LAEI), and the list of schools used is from Edubase public portal from the Department of Education. <br /><br /> The list is shown by borough and in descending order with the most polluted first. Further analysis of this data and other indications of the links between air pollution and social gradient in London can be found in the <a href="/dataset/analysing-air-pollution-exposure-in-london/resource/0925e909-9e44-4de3-ae72-97497d3c8511">Updated Analysis of Air Pollution Exposure in London</a>.</li>

本数据集于2017年2月更新。

近年来，得益于以道路交通运输减排为核心的多项政策，伦敦空气质量已显著改善。但2013年污染浓度最新地图（LAEI 2013）仍显示，大片区域的二氧化氮（NO₂）年均浓度超出欧盟法定限值标准。正如伦敦市长近期公布的空气质量治理一揽子计划所言，相关部门已规划针对此类问题的改进措施。

1. 由伦敦市政厅近期发布的《伦敦空气污染暴露状况更新分析》（Updated Analysis of Air Pollution Exposure in London），是对2013年同类分析（该分析聚焦2010年伦敦的污染暴露情况）的更新。本研究考察了2013年伦敦的污染暴露状况，并分析了暴露水平随年龄、相对贫困程度及族群等指标的变化差异；同时还统计了全市各自治市的总污染暴露量，以及学校区域的污染暴露情况。

通过本报告中的研究，伦敦市政厅旨在厘清伦敦民众在获取清洁空气方面存在的不平等问题，并探讨如何通过规划中的空气污染治理政策改善这一现状。

2. 本电子表格列出了二氧化氮（NO₂）平均浓度超出欧盟法定安全限值的区域内的学校，欧盟限值标准为40微克/立方米（μg/m³）。本报告所使用的模拟二氧化氮浓度数据来自2013年伦敦大气排放清单（LAEI 2013），学校名录则取自英国教育部的Edubase公共门户。

该列表按伦敦自治市分类，并以污染程度从高到低排序，污染最严重的学校位列前列。关于此数据集的进一步分析，以及伦敦空气污染与社会分层之间关联的更多研究结果，均可参阅《伦敦空气污染暴露状况更新分析》（Updated Analysis of Air Pollution Exposure in London）。
