Air quality along roads 2014 (monitoring round 2015)

The National Air Quality Cooperation Programme, which has been in force since 1 August 2009, contains a package of measures to ensure timely compliance with European limit values throughout the Netherlands. In doing so, account has been taken of the effects of spatial developments on which a decision is taken within the duration of the NSL. From 2010 onwards, an annual monitoring of the NSL takes place. It monitors the development of air quality and keeps track of the implementation of the measures and projects included in the NSL. For the purpose of this monitoring, calculations are carried out with the Monitoring Tool. If the monitoring shows that the objectives of the NSL are not being met, additional measures may be taken. The limit value for NO2 (nitrogen dioxide) is 40 ug/m³, and it must be reached at NSL test points in 2015. The limit values for PM10 are 40 ug/m³ annual average and a daily average of 50 ug/m³, which however corresponds to 31.2 ug/m³ annual average. The fine dust limit value should be reached in 2011.自2009年8月1日起施行的《国家空气质量合作计划》（National Air Quality Cooperation Programme）包含一系列政策措施，旨在确保荷兰全境及时符合欧盟空气质量限值标准。制定本计划时，已充分考量在计划实施周期内作出决策的空间开发活动带来的影响。自2010年起，该计划（NSL）每年开展一次监测工作：监测空气质量变化情况，并跟踪计划内各项措施与项目的落实进展。本次监测依托监测工具（Monitoring Tool）开展相关计算。若监测结果显示未达成计划设定目标，则可采取额外补充管控措施。二氧化氮（nitrogen dioxide，NO2）的限值标准为40微克/立方米，需在2015年于NSL监测点位达标。可吸入颗粒物（PM10）的限值标准为年平均40微克/立方米、日平均50微克/立方米，但其日平均限值对应的等效年平均限值为31.2微克/立方米，该细颗粒物限值需在2011年达标。
