Chemical Air Pollution And Male Fertility In The Province Of Lublin In Poland In The Years 2011-2016

Air pollution is the world's single biggest environmental health risk.Poland and Bulgaria have the dirtiest sky in Europe. Air pollution can adversely affect male fertility. In thestudies investigating the effects of air pollution on male infertility there are no clear references to changes in men's semen parameters in recent years in Poland.Studies from Western Europe is an issue of concern because of clearly observed decline in the major exponents of male fertility. The aim of the present study was to evaluate the effect of sulfur dioxide (SO2), ozone (O3), nitrogen dioxide (NO2) and dust particulate matter (PM 2,5) on sperm quality .We analyzed spermiograms of patients making a first-time appointment to treat infertility in the Lublin province, and the database of the Chief Inspectorate of Environmental Protection concerning the monitoring of selected chemical elements of air pollution (2011-2016).Analyses covered thespermiograms of 6000 men living in the examined regions for at least 3 years. The results of the studies obtained were subjected to statistical analysis. It has been shown that the concentration of NO2, SO2, PM 2.5 and O3 contributes to a decrease in the percentage of morphologically normal spermatozoa, without affecting other semenparameters.The results of this study give rise to the need for action to reduce the emission of air pollution as well individual protection of the individual from their effects. Key words - Semen, particulate matter, sulfur dioxide, nitrogen dioxide, ozone
