Luftqualität heute: Wie gefährlich ist die Feinstaubbelastung in Hannover?

On March 3, 2025, the air quality was analyzed at the measuring station on Göttinger Strasse, Linden-Süd, Hanover. The measurement captured the fine dust particles (PM10) per cubic meter of air. Ограничението за PM10 е 50 микрограма на кубичен метър въздух и може да бъде надвишена максимум 35 пъти през годината, като hannoversche allgemeine zeitung докладва.

The air quality is evaluated using three characteristic values: fine dust, nitrogen dioxide and ozone. Ограничените стойности се дефинират по следния начин: за стойности над 200 µg/m³ за азотен диоксид, над 100 µg/m³ за фин прах и над 240 μg/m³ за озон, условията се считат за "много лоши". Стойностите между 101 и 200 µg/m³ за азотен диоксид, 51 и 100 µg/m³ за фин прах, както и 181 и 240 µg/m³ за озон се класифицират като „лоши“. Категорията „умерена“ струва между 41 и 100 µg/m³ за азотен диоксид, 35 и 50 µg/m³ за фин прах и 121 и 180 µg/m³ за озон. The measurement is hour means for nitrogen dioxide and ozone as well as an hourly gliding daily remedy for fine dust.

recommendations in poor air quality

The 240,000 premature deaths registered in the EU annually lead to recommendations for the population. In the case of "very bad" air quality, it is recommended that sensitive people avoid physical exertion outdoors. With “bad” air quality, less sensitive people should be careful and avoid exhausting outdoor activities. With a "moderate" assessment, short -term health effects are rather unlikely, but these can occur in sensitive people. Въпреки че няма здравни ефекти с „добро“ качество на въздуха, най -добрите условия за дейности в чистия въздух са под „много добро“ качество на въздуха.

In addition, it was pointed out that fireworks qualm mostly consists of fine dust harmful to health. Around 2050 tons of fine dust are released annually, with 75% (1500 tons) of which are being created on New Year's Eve.

като Екологичен федерален офис на околната среда Допълнени, фини измервания на прах. The PM10 annual means have dropped to between 15 and 20 µg/m³ in recent years, which corresponds to a decline of 50 µg/m³ in the 1990s. Lower values ​​are recorded for rural areas. A reliable measurement data acquisition in metropolitan areas is crucial because numerous issuers such as traffic and industry are active there. Since 2012, the annual limit values ​​of 40 µg/m³ have been exceeded at no measuring location.
