according to A study, the fine dust may contribute to more premature deaths than previously thought. How the ARD-magazine "Monitor" reported on Thursday in advance speaks a Meta-study by the Max-Planck-Institute (MPI) for chemistry of around 120,000 premature deaths due to fine dust in Germany. Agriculture is a major contributor. In the world of fine dust contributes to around nine million premature deaths.
the fine dust with the smoke
The Mainz Max-Planck compared the Institute based its study on 40 international studies from 16 countries, whose data were collected over the decades. The increase in the data Foundation is one of the reasons that the researchers would be well to higher Numbers, said study leader Jos Lelieveld in the report. Thus, the fine dust was for about as many premature deaths as Smoking.
With a share of about 45 percent in agriculture, and especially livestock farming as the main cause for Germany's ruling burden from fine dust is regarded according to the researchers. The reason is that ammonia escapes through the decomposition of manure and fertilizer from crops into the atmosphere and combines with other gases, such as sulphur and nitric acid. It fine dust particles.
mass animal farming leads to more fine dust
"The mass of animal husbandry leads to ammonia, ammonia leads to a fine dust, and fine dust leads to premature deaths," said Lelieveld. In this context, among experts known for years. A previous study by the MPI showed that the reduction of agricultural ammonia emissions can reduce the mortality due to air pollution considerably.
Germany had committed itself in 2001 to limit ammonia emissions from 2010 for a value of 550,000 tons per year. Indeed, but the value is exceeded regularly for years, as it is said in the report.More about

An increased burden of fine dust is associated with respiratory and cardiovascular problems. The smallest particle of mountains, the greatest danger to the health because they can penetrate deep into the lungs. (AFP)
