Horsham District Council Air Quality Areas

Horsham District Council Air Quality Management Areas. The Council's Environmental Health Section undertakes monitoring for Nitrogen Dioxide (NO2) at sites throughout the district. Nitrogen dioxide is a colourless gas produced by combustion processes and is emitted from vehicle exhausts. It can have an adverse health impact at high levels. To protect the public a level is set by legislation that is sufficiently low that the concentration of nitrogen dioxide normally found is unlikely to have any health effects. Where levels exceed the permitted limits the Council can designate an Air Quality Management Area. The locations of the current area/s are shown by this data. Polygon data captured against Ordnance Survey Mastermap from boundary alignments marked on official designation maps. Attribute fields included:
1. FID = Area reference;
2. NAME = Location of designated area.

霍舍姆区议会空气质量管理区域。区议会环境卫生部门负责对整个区域内的氮氧化物（NO2）进行监测。氮氧化物是一种无色气体，由燃烧过程产生，并来自汽车尾气排放。在高浓度下，它可能对健康产生不利影响。为保护公众健康，立法设定了足够低的水平，使得通常发现的氮氧化物浓度不太可能产生健康效应。当水平超过允许的限度时，区议会可指定空气质量管理区域。当前区域的地理位置由本数据展示。该数据基于官方指定图上的边界对齐线，从地形测量局主图捕获的多边形数据。包含的属性字段如下：
1. FID = 区域参考编号；
2. NAME = 指定区域的位置。
