Today, March 31, 2024, Bremen is particularly suffering from fine dust pollution. News.de keeps you informed about the existing danger with the help of daily measurement results.
The air quality index (LQI) is an indicator of how good the air currently is. To do this, the concentrations of five different pollutants (carbon monoxide, nitrogen dioxide, particulate matter PM10 and PM2.5, ozone and sulfur dioxide) in the air are measured. These all have prescribed limit values according to which they are classified into different risk levels. There are five risk levels (green, yellow, orange, red, violet and dark red) that are based on the LQI. The maximum LQI that can be achieved and therefore the most dangerous on the scale is 500. We look at which LQI Bremen today and what that means for your health.
Air pollution in Bremen currently: High levels of fine dust
Die Air quality in parts of Bremen is lying in orange area. At the location Oslebshausen The air quality index recently reached its highest value of 155. Air pollution can be classified as unhealthy, at least for sensitive people. The main pollutant is in the atmosphere particulate matter. Sensitive groups of people can be affected by air pollution. You should take precautionary measures to protect your health.

For sensitive groups of people (e.g. asthmatics), additional stimuli (e.g. pollen count) could have short-term adverse health effects. However, it is unlikely. Reduce physically strenuous outdoor activities.
What is fine dust and how is it created?
Fine dust is a complex collection of small pollutant particles. Depending on the size of the solid and liquid particles, particulate matter is classified as either PM10, PM2.5 or PM1. PM stands for the size of the particles, which is 10 micrometers (µm), 2.5 µm or less than 0.1 µm.
Because of brake and tire wear, combustion engines and the road dust that vehicles throw up, road traffic is one of the main sources of fine dust pollution. The level of pollutants in the air is also increased by emissions from power plants and combustion plants as well as by soot and coal particles from forest fires and volcanic eruptions. Furthermore, agriculture contributes to the secondary formation of fine dust with ammonia emissions from livestock farming.
Effects of fine dust pollution on health
The smaller the particles, they can penetrate deeper into the respiratory tract. PM10 only reaches the nasal cavity, but PM2.5 even reaches the bronchi and the ultrafine particles PM1 penetrate into the alveoli and the bloodstream. Therefore, inhaling fine dust can lead to inflammation of the respiratory tract and irritation of the mucous membranes. Fine dust particles in the blood can lead to or worsen cardiovascular diseases in the long term.

Why is air quality so bad in some areas?
The world’s leading cause of bad air is the burning of fossil fuels.
This happens in various areas: In private households, pollutants and fine dust particles are formed when fuels and wood are burned for cooking, heating and lighting or fireworks are shot into the air. Chemicals used for cleaning and painting can also pose an additional burden because they often contain toxic lead. Furthermore, solvents and chemicals used to extract natural resources in mining pollute the air.
In addition, 40% of the world’s open waste incineration ensures that methane, dioxide and black carbon, among other things, are released into the atmosphere in landfills.
In the manufacturing industry, the combustion of fossil fuels is one of the main triggers for the emission of harmful gases and particles (e.g. carbon monoxide, carbon dioxide, nitrogen dioxide and sulfur). But internal combustion engines that use fossil fuels as fuel (diesel, petroleum, etc.) also contribute to the deterioration of air quality. Ships of all kinds and aircraft, along with cars and trucks, are major pollutant emitters. The whirling up of dust and tire abrasion in road traffic also increases fine dust pollution, which can lead to problems, especially in large cities.
Another reason for air pollution is fertilizers and pesticides from agriculture and livestock farming. This produces ammonia, methane gas and other harmful gases. The particularly bad thing about methane gas is that it contributes to the creation of harmful ground-level ozone, which poses a threat to good air quality, especially in summer.
But although the majority of the causes of air pollution are man-made, there are also natural phenomena that contribute: forest fires produce fine smoke particles that can reach the lungs, and volcanic eruptions release large amounts of sulfur dioxide.
