Air measurement values for benzene — annual averages Düsseldorf since 1995

The dataset contains the annual average values for benzene in Düsseldorf since 1995 from the urban measuring stations. The values are expressed in µg/m³. Data on other pollutants are provided in datasets on ozone and soot. In addition to the archive data for fine dust (daily values for fine dust), fine dust data on exceedance days and annual average values are also available. Similarly, the load is treated with nitrogen oxides. Here you will find the time series as archive data, the annual averages and also the most up-to-date measured values. The files with the most up-to-date values are automatically supplemented once per hour by another measured value. The spatial information of the urban measuring stations is available in a separate dataset. The state capital of Düsseldorf carries out air quality measurements and evaluates the results on the basis of the legal basis. It is currently the Federal Immission Protection Act in combination with the 39. Federal Immission Control Regulation. Further information can be found on the ‘Air Quality’ page of the Environmental Agency. Further information sources can be reached via the links of the ‘Online Data’ page. The files contain the following column information: Year: Annual averages Summaries: Values of the measuring station at Ludenberger Allee (measurements discontinued at the end of 2013) Doro: Values of the measuring station on Dorotheenstraße BRINCK: Values of the measuring station at Brinckmannstraße Aaper: Values of the measuring station in the Aaper Forest (measurements discontinued at the end of 2013)本数据集收录了自1995年起，杜塞尔多夫市区各空气质量监测站测得的苯年均浓度值，单位为微克每立方米（µg/m³）。 臭氧及烟尘类污染物的相关数据已收录于其他专项数据集。 除细颗粒物的归档日度数据外，本数据集还涵盖细颗粒物的超标日统计数据与年均值数据。 针对氮氧化物，数据处理逻辑与上述污染物一致，包含归档时序数据集、年均值数据以及最新实测值三类内容。其中存储最新实测值的文件每小时会自动补充一条新的监测数据。 市区监测站的空间位置信息已单独收录于独立数据集。 作为联邦州首府，杜塞尔多夫依据法定框架开展空气质量监测与结果评估工作，现行依据为《联邦排放保护法》（Federal Immission Protection Act）及《第39号联邦排放控制条例》（39. Federal Immission Control Regulation）。 更多相关信息可查阅环境署的「空气质量」专题页面，其他数据源可通过「在线数据」页面的链接获取。 各数据文件包含以下字段信息： - Year：年均值相关数据 - Summaries：卢登贝格大街（Ludenberger Allee）监测站监测数据（该站点监测工作已于2013年底终止） - Doro：多罗特恩大街（Dorotheenstraße）监测站监测数据 - BRINCK：布林克曼大街（Brinckmannstraße）监测站监测数据 - Aaper：阿珀森林（Aaper Forest）监测站监测数据（该站点监测工作已于2013年底终止）
