The relationship between air pollution and exacerbation of respiratory diseases is well established. Nevertheless, its association with hemoptysis has been poorly investigated. This paper describes the relationship of air pollutants with severe hemoptysis.<jats:italic>Methods<\/jats:italic>. All consecutive subjects with severe hemoptysis during a 5-year period were included. The relationship between the contamination measurements and the frequency of embolizations was analyzed using Poisson regressions. In these regressions, the dependent variable was the monthly number of embolizations in a given month and the independent variable was either the concentration of an air contaminant during the same month, the concentration of the air contaminant during the previous month, or the difference between the two.<jats:italic>Results<\/jats:italic>. A higher total number of embolizations per month were observed over the months with increases in the concentration of NO. The number of embolizations was 2.0 in the 33 months with no increases in the concentration of NO, 2.1 in the 12 months with small increases, 2.2 in the 5 months with moderate increases, 2.5 in the 4 months with large increases, and 4.0 in the 5 months with very large increases.<jats:italic>Conclusion<\/jats:italic>. There is association between hemoptysis and increases in the concentration of atmospheric NO in Badalona (Spain).<\/jats:p>","DOI":"10.1155\/2016\/9242185","type":"journal-article","created":{"date-parts":[[2016,3,15]],"date-time":"2016-03-15T04:08:14Z","timestamp":1458014894000},"page":"1-5","source":"Crossref","is-referenced-by-count":5,"title":["Association
