The paper provides a concise review of key publications on particulate matter of aerodynamic diameter below 1 μm (PM1) having been published in Poland in the years 2007–2022. Data and conclusions related to the study of concentrations, chemical composition, and content of selected toxic and carcinogenic compounds in PM1 as well as methods and conclusions on the assessment of the origin of PM1 in various regions of Poland have been tabulated. The conclusions of this review attempt to outline the directions of further research that could prove crucial in obtaining information and filling the identified gaps in knowledge about PM1 in Poland. While this work may be theoretical, it can serve as a valuable and compact source material for research groups, organizations supervising and financing research, as well as those responsible for assessing air quality and mitigating negative health effects related to air quality.

The circulation of heavy metals in nature is characterized by high toxicity. However, the effects depend on the amount of toxic, the form of exposure to toxicity, the types of species exposed, age, sex, genetics and nutritional status, and on the consequences in ecosystems. With the onset of the COVID-19 pandemic, the environmental situation in some regions has deteriorated even more due to poor monitoring by state institutions. The challenges that await us in the future are complex and hence we risk not knowing how to meet the future challenges. The situation with toxicity and pollution is complicated by the COVID-19 pandemic, which for the first time in this century has turned into a global pandemic. Although we were not prepared to cope with this pandemic, still we succeeded to manage it better than the previous pandemics. High concentrations of heavy metals such as arsenic, cadmium, lead, and nickel are among the metals that are dangerous for the public health of citizens. Metallic elements are characterized by toxic effects, especially with the consumption of food products. High concentrations cause great damage to human and animal organs but sometimes even small concentrations of it can have harmful effects. The increase in toxic concentration has affected industrial development, poor waste management, the release of toxic gases from industrial activities, as well as use of pesticides and herbicides in agriculture. High toxicity causes health damage, e.g. resulting from human exposure to metal toxicity and the use of contaminated foods. The heavy metals present in the environment such as Cu, Fe, Mg, Mn, Ni, Se, Zn, Co, Cr, are essential nutrients required for various biochemical and physiological functions.

Air pollution is a global problem. In Europe, ambient air quality remains poor in many areas, particularly in urban ones. Air pollutants have a significantly adverse effect on human health and ecosystems. They are the main cause of many serious illnesses and thus contribute to increased mortality. This paper analyzes the air pollutant emissions in the last four years (2018–2021) in the Upper Silesian Region, which has one of the worst air qualities in Poland and in Europe in general, and the emissions in the Lublin Region in eastern Poland, which is considered as a clean region. In each of the above-mentioned regions, the areas with the highest air pollutant emissions were specified i.e. the Upper Silesian Agglomeration and the Lublin Agglomeration. The emission data for the following pollutants: particulate matter (PM10, PM2.5), benzo(a)pyrene (BaP), sulfur oxides (SOx) and nitrogen oxides (NOx) have been compared. The obtained results were also compared with the estimated average emissions in Poland. It was indicated that in both agglomerations the exposure to air pollutants was on similar levels, which were several times higher than in the remaining parts of the considered regions and the average values for Poland in general. In the Silesian Agglomeration, the exposure to PM10 was over 5 times higher than the average national exposure. The exposure to PM2.5 was almost 6 times higher, the exposure to BaP was about 5 times higher, while the exposure to SOx and NOx was 16 and 10 times higher than the national average, respectively. This is reflected in the increased number of premature deaths and the number of years of life lost due to the exposure to air pollution. Therefore, the actions aimed at limiting air pollutant emissions are urgent in the above-indicated areas.

W wielu krajach rozwiniętych, także i w Polsce, zaburzenia zdrowia spowodowane niewłaściwym sposobem odżywiania występują bardzo często. Zjawisko to związane jest głównie z nadmiernym spożyciem tłuszczów oraz ich niekorzystnym żywieniowo składem. Jednym ze wskaźników jakości zdrowotnej diety jest poziom spożycia wielonienasyconych kwasów tłuszczowych grupy omega-3 i jego proporcja do kwasów grupy omega-6. W tzw. diecie typu zachodniego proporcja ta znacznie odbiega od prawidłowej w wyniku zbyt wysokiego poziomu spożycia kwasów omega-6 wraz z tłuszczami roślin-nymi i zbyt niskiego - omega-3. Przyczynia się to do zwiększenia ryzyka rozwoju wielu schorzeń, dlatego obecnie zaleca się m.in. znaczne zwiększenie udziału kwasów omega-3 w diecie.
