Particulate matter (PM10) Itzehoe 1-hour average 2023

In order to protect people’s health and vegetation from the influences of excessive air pollution, air quality is continuously examined and assessed according to legal regulations. For this purpose, the State Office for the Environment (LfU) in Schleswig-Holstein operates a network of measuring stations at which air pollutants are measured using different methods. The measurement data from Schleswig-Holstein and many additional information on the measurements are forwarded to the Federal Environment Agency and reported to the European Commission together with the data of all federal states. All currently published data must be classified as ***provisional***, as they are first checked for validity for your quick information. Before the final assessment and assessment of air quality, a multi-stage inspection according to legal requirements will take place later. In the CSV files, on the day of the change from normal time (CET) to daylight saving time (CEST) the 3 o‘clock measurement is missing, but on the day of the conversion from summer to normal time, there are two 3 o’clock measurements. The JSON files are not affected by this problem, here normal time is used throughout. [Information on the measuring station](https://www.schleswig-holstein.de/DE/Fachinhalte/L/luftqualitaet/Messstationen/ItzehoeOelixdorfer.html)为保护民众健康与植被免受过度空气污染的不利影响，各国需依据法律法规持续开展空气质量监测与评估工作。 为此，石勒苏益格-荷尔斯泰因州环境局（State Office for the Environment，LfU）搭建了监测站网络，采用多种方法对空气污染物进行测定。 来自石勒苏益格-荷尔斯泰因州的监测数据，以及诸多与本次监测相关的补充信息，将被报送至德国联邦环境署，并与全联邦各州的监测数据一同上报至欧洲委员会。 目前所有已发布的数据均归类为**临时数据**，因它们仅为供快速参考而完成了初步有效性核验。在最终开展空气质量评定与评估工作前，后续还将依据法定要求开展多阶段核查。 在CSV文件中，当从标准时间（CET，Central European Time）切换至夏令时（CEST，Central European Summer Time）的当日，3时的监测数据会缺失；而在夏令时切换回标准时间的当日，则会存在两条3时的监测数据。JSON文件不受此问题影响，全程采用标准时间。 [监测站信息](https://www.schleswig-holstein.de/DE/Fachinhalte/L/luftqualitaet/Messstationen/ItzehoeOelixdorfer.html)
