Polluted air shortens life by two years

Every German dies on average two years earlier by polluted air. That was the result of a study. Fine dust in particular is causing immense damage in the lungs.

In spite of stricter regulations, the emission of harmful particulate matter from private wood stoves is increasing. In contrast to diesel cars, however, there is no filter obligation. In addition, there is a reason why exactly these particles are so dangerous.

D ie German Environmental Aid (DUH) Calls for a faster reduction of particulate matter emissions Stoves . " We call for a mandatory installation of particle separators for new equipment in the short term. An obligation to retrofit existing devices must follow as soon as possible, " said Patrick Huth, DUH project manager for traffic and air pollution control, to WELT AM SONNTAG.

According to environmental assessments, the emission of soot and fine dust particles from so-called single-room combustion plants will not go back, despite stricter regulations, but will even take place. This is also due to the fact that even new devices do not have a filter requirement. "It is incomprehensible to us that a particulate filter is prescribed for diesel cars, but not in the case of ovens," says DUH expert Huth.

According to WELT AM SONNTAG, there is also criticism of the fine-dust measurement method. "The fine dust emissions are measured mainly in the big cities-where there is a lot of traffic," said Axel Friedrich, retired environmental official and expert on transport and air pollution control, the newspaper. Wood stoves but especially in more rural areas or on the outskirts of the city. "In this respect, we measure in the wrong places," Friedrich said.

In addition, the wrong particles would be registered. In transport and industry, it is mainly particles with a size of up to ten micrometers (PM10). Wood fire, on the other hand, produced many particles with a maximum size of 2.5 micrometers. "The problem is that these PM 2.5 shares will not be measured," Friedrich said. "We have to change the measurement methods," the expert asks.

The German Environmental Aid (Deutsche Umwelthilfe) estimates the proportion of micro-particles that are harmful to health from single-room fireplaces as particularly high: " About 90 percent of the particles that are produced in wood burning are smaller than one micrometer. These penetrate particularly deeply into the lungs and the bloodstream, " the website of the Association of Interests states. In addition, larger particles of soot, according to DUH, would be CO2 as the second-largest polluter of the greenhouse effect.

According to information provided by the Federal Environment Agency, there are around eleven million fireplaces and fireplaces in German households. About four to five million of these do not yet meet the current requirements of the Federal Immission Control Regulation and have to be replaced gradually.

For example, by the end of 2020, stoves with a date of manufacture between January 1985 and December 1994 (according to the nameplate) must be replaced or retrofitted to comply with the applicable emission levels. For furnaces from the years 1995 to March 2010, consumers have until the end of 2024 to have time for replacement or retrofitting.
