        abstract = {Poor health in Poland makes Poland an interesting case for mortality research, Poland has one of the highest lung cancer rates in Europe and also a high prevalence of cardiovascular mortality. The same time Poland is the most polluted country in Europe with regard to air quality. So it is likely that air pollution is a significant factor on mortality in Poland.
This research is done through regional mortality differences, with multiple regression analyses. Looking at the results, no significant outcomes are found between air pollution and mortality. Only for smoking are significant outcomes found, neither for alcohol, overweight and income. So at the end can only be concluded that smoking is a significant factor on mortality. This means that only smoking could explain some of the regional mortality differences. This makes it likely that smoking disrupted the outcomes for the air pollution research, as it leads to the same diseases.}
