Flächennutzungsplan der Stadtgemeinde Bremen: Gemäß Baugesetzbuch (BauGB) ist der Flächennutzungsplan der vorbereitende und damit der übergeordnete Bauleitplan einer Gemeinde. Das Verfahren zur Aufstellung des Flächennutzungsplanes ist im Baugesetzbuch (BauGB) geregelt. Der Flächennutzungsplan stellt die gegenwärtige und die geplante Bodennutzung, nach den voraussehbaren Bedürfnissen der Gemeinde, für das gesamte Gemeindegebiet in den Grundzügen dar. Die Darstellungen des Flächennutzungsplans bilden die Grundlage für die detaillierten Festsetzungen der Nutzung der Grundstücke, da die für Teilgebiete der Gemeinde aufzustellenden Bebauungspläne (verbindlichen Bauleitplanung) aus dem Flächennutzungsplan zu entwickeln sind. Der Flächennutzungsplan ist nur für die Gemeinde und die öffentliche Planungsträger verbindlich.

This dataset provides data from various air quality sensors at a floating platform of the Federal Institute of Hydrology at the river bank of the Rhine in Koblenz, Germany. The data was collected as part of the mFUND project "REIN" which investigated the suitability of low-cost sensors for the determination of ship emissions with high spatial and temporal resolution. Measurement data involves various pollutants, including nitrogen oxides (NO, NO2), carbon dioxde (CO2) and particulate matter (particle number concentration, mass concentration, size distribution, ultrafine particles, black carbon concentration). Averaged data is provided at 1 minute and 1 hour temporal resolution and covers both low-cost and standard instruments. The dataset is related to the publication "Applicability of compact low- and mid-cost sensors to monitor air pollutant emissions from in-land ships".
Als ultrafeine Partikel werden Teilchen mit Durchmessern kleiner als 100 nm bezeichnet. Die ultrafeinen Partikel entstehen in Verbrennungsprozessen, die unter Sauerstoffmangel stattfinden. Hierbei sind u.a. der Straßenverkehr mit seinen unzähligen instationären Verbrennungen, Industrieprozesse und Hausbrand zu nennen. Partikel dieses Größenbereichs können sehr spezielle chemische oder physikalische Wechselbeziehungen mit der Umgebung eingehen. Man beobachtet bei ultrafeinen Partikeln vorwiegend Diffusion, wogegen sich größere Teilchen eher durch Anlagerung bzw. Sedimentation auszeichnen (Limbach, 2005). In der Europäischen Union gilt seit Januar 2005 ein Grenzwert für Feinstaub, d.h. für Partikel kleiner als 10ìm (PM10), vorgeschrieben. Für ultrafeine Partikel gibt es in Europa bisher keine eigenen Grenzwerte. In einem bis dahin einmaligen Projekt wurde die Entwicklung der Belastung mit ultrafeinen Partikeln in Erfurt über zehn Jahre quantitativ bestimmt. Dabei wurde ein deutlicher Anstieg festgestellt (Krug, 2005). Die Korngrößen des Ultrafeinstaubs können das menschliche Respirationssystem erreichen. Man spricht daher vom inhalierbaren Anteil des Feinstaubs. Partikel kleiner als 100 nm werden als noch gefährlicher eingestuft, da sie lungengängig sind. Wegen ihrer geringen Größe können einzelne ultrafeine Partikel ein Lungenepithel durchqueren. Ein Weitertransport zu Leber, Knochenmark oder Herz ist möglich. Die Ultrafeinpartikel können sich in der Lunge bis zu mehreren Monaten ablagern bzw. verbleiben (WHO,1997). Es sind einige Verfahren entwickelt worden, um die PAK-Belastung auf Menschen zu erfassen und ihre Auswirkungen zu beschreiben. Dabei wurde Benzo(a)Pyren oft als Indikator für die Präsenz von karzinogenen PAK in der Umwelt genutzt. Verbreitet ist zum Beispiel die Bestimmung von PAK in Blut oder Urin und die Untersuchung der Auswirkungen von PAK auf den Metabolismus in Organen wie Niere und Leber (Larsen, 1995). Die Exposition durch NPAK erfolgt hauptsächlich über die Luft. Es gibt bislang wenige Studien, welche die Langzeitwirkung der inhalativen Aufnahme untersuchen. Darüber hinaus gelten auch die Metaboliten der NPAK als kanzerogen (Uhl, 2007). Laut WHO gibt es erheblichen Forschungsbedarf hinsichtlich der Exposition der Menschen und der Wirkungen von NPAK auf die menschliche Gesundheit (IPCS 2003). Obwohl die NPAK nur einen Bruchteil (1 bis 10Prozent) der PAK ausmachen (Nielsen, 1984), ist spezielle Aufmerksamkeit wegen ihrer hohen biologischen Aktivität notwendig. Zahlreiche NPAK wirkten in Tierversuchen deutlich mutagen und kanzerogen (Fiedler et.al, 1990). Über ihr Verhalten und ihre Anreicherung in Boden und Staub ist bis jetzt noch sehr wenig bekannt. Ebenso wenig wie über deren Metabolismus und Akkumulation in biologischem Gewebe (Fiedler et al., 1991, Fieder und Mücke 1990). (...)
Exposure to ultrafine aerosol particles (UFPs) can cause adverse effects on human health, local environment and climate. Air traffic is associated with the emission of high numbers of UFPs, which results in increased UFP number concentrations close to airports. So far, the spatial distribution and variability of UFPs is poorly understood in the atmospheric boundary layer. The uncrewed aerial system (UAS) ALADINA (Application of Lightweight Aircraft for Detecting In-situ Aerosols, e.g. Altstädter et al., 2015) was operated close to the largest airport in Germany at Frankfurt airport (FRA) between 11 and 19 October 2024. The dataset provides airborne in-situ observations of the spatial distribution of aerosol particle number concentration with different sizes and meteorological parameters of temperature, humidity, wind, surface temperature and short-wave irradiance, as well as accurate position and orientation of ALADINA. Data are available from 26 measurement flights, comprising a number of 122 vertical profiles between ground and a maximum altitude of 750 m above mean sea level (ASL) and about 70 horizontal legs at different but constant altitude, e.g. in 100 m altitude intervals. Details about the ALADINA measurements will be provided in a publication (Harm-Altstädter et al., in prep.) soon.
This dataset provides air quality data from parallel on-board and onshore measurements of ship exhaust emissions as well as data from a simulation (with the large-eddy model PALM) at the Dortmund-Ems canal in Germany. Measurement data involves various pollutants, including nitrogen oxides (NO, NO2), carbon dioxde (CO2) and particulate matter (particle number concentration, mass concentration, size distribution, ultrafine particles, black carbon concentration). The dataset is related to the publication "Connecting inland ship emissions from on-board sampling, onshore measurements and large-eddy simulations".
