摘要
Over the past few years, research on the quality of air and microorganisms presen</span><span style="font-family:Verdana;">t in the atmosphere and spore composition of the environment has increased significantly, due to concerns over health risks for humans, plants, and animals. This study shows the abundance and diversity of microorganisms </span></span><span style="font-family:Verdana;">and </span><span style="font-family:Verdana;">the</span><span style="font-family:""><span style="font-family:Verdana;"> atmosphere of an urban nucleus, that is, the city of Valladolid (Spain). We considered the conditions of precipitation, humidity </span><span style="font-family:Verdana;">and</span><span style="font-family:Verdana;"> wind, and the presence of some atmospheric pollutants such as nitrogen dioxide and nitrogen monoxide (NO</span><sub><span style="font-family:Verdana;">2</span></sub><span style="font-family:Verdana;">/NO), carbon monoxide (CO), sulfur dioxide, and particulate matter (</span></span><span style="font-family:Verdana;"><i></span><i><span style="font-family:Verdana;">PM</span></i><i><span style="font-family:Verdana;"></i></span></i><span style="font-family:Verdana;">10 and </span><span style="font-family:Verdana;"><i></span><i><span style="font-family:Verdana;">PM</span></i><i><span style="font-family:Verdana;"></i></span></i><span style="font-family:""><span style="font-family:Verdana;">2.5).

Gram-positive bacteria were present at a low rate.
