Ground level (tropospheric) ozone, an air pollutant and key ingredient of urban smog, has a negative impact on human health worldwide. Many studies have reported increases in emergency-room visits, hospital admissions, and mortality for patients with these conditions, associated with days of increased ozone. Short-term exposures to ozone irritate the respiratory system and may cause health problems by damaging lung tissue, reducing lung function, increased airway inflammation and making the lungs more sensitive to other irritants. It not only affects people with existing breathing problems, but also can affect healthy children and adults. Persons especially sensitive to ozone exposure are the elderly, infants, children, persons with existing respiratory issues such as diabetes mellitus, asthma or allergies, asthmatics, chronic respiratory patients, pregnant women, smokers, and persons with lung cancer, cardiovascular disease or immune system deficiency. Furthermore, recent research studies suggest that long-term exposure to ozone may be associated with lung cancer. This possibility is expected to be further explored.

Objectives: Ambient ozone (O₃) exposure is associated with a variety of health conditions. The objective of this study was to examine the effect of increased daily concentrations of ozone on emergency department (ED) visits due to lower respiratory diseases (LRD), such as acute or chronic bronchitis, in Edmonton, Canada. Materials and Methods: Data concerning 10 years (1992-2002) were obtained from 5 Edmonton hospital Emergency Departments. Odds ratios (ORs) for ED visits associated with the increased ozone levels were calculated employing a case-crossover technique with a time-stratified strategy to define controls. In the constructed conditional logistic regression models, adjustments were made for daily number of influenza ED visits and weather variables using natural splines. ORs and their 95% confidence intervals (95% CI) were reported in relation to an increase in the interquartile range (IQR = 17.9 ppb) of the ground-level ozone. Results: Overall, 48 252 ED visits due to LRD were identified, of which 53% were made by males. The presentations peaked in December (12%) and February (11.7%) and were the lowest in August (5.6%). Positive and statistically significant results were obtained for acute bronchitis: for same day (OR = 1.09, 95% CI: 1.05-1.13, lag 0) and for lag 2, lag 3-7 and 9 days; for chronic bronchitis: for lag 6, 7, and lag 9 days (OR = 1.11, 95% CI: 1.05-1.18, lag 9). For all ED visits for LRD, lag 0, lag 1, and lag 3-9 days showed positive and statistically significant associations (OR = 1.06, 95% CI: 1.03-1.09, lag 0). Conclusions: These findings support the hypothesis concerning positive associations between ozone and the ED visits due to LRD.

The COVID-19 pandemic is currently one of the major global health and economic challenges. An efficient method for reducing the transmission of the virus is a still unmet medical need. Existing experimental data have shown that coronavirus survival is negatively impacted by ozone, high temperature, and low humidity. Therefore, it is feasible to use area ozonation in pharmacies – the front line of the healthcare system. Nevertheless, further work is needed to evaluate the effectiveness of ozone disinfection to reduce the transmission of this virus in pharmacies, hospitals, and other public environments.

Objectives Ambient air pollution, as many publications indicate, may have associations with skin condition. The aim of this study has been to examine such common relations for cellulitis and pharyngitis. The hypothesis is that ambient ground-level ozone may help bacteria to penetrate skin or throat. Material and Methods We used the emergency department (ED) visits data in Edmonton, Canada for the period from 1992 (April) to 2002 (March). We retrieved all the diagnosed ED visits for cellulitis and pharyngitis. Case-crossover design was used to study potential association between ozone and those visits. Conditional logistic regression was used to estimate odds ratios (OR) and their 95% confidence intervals (95% CI). Results The results are reported for the interquartile range (IQR = 17.9 ppb) for 8 h maximum ozone. Positive and statistical significant results were obtained as follows: for lags from 0 to 3 (OR = 1.07, 95% CI: 1.03–1.12, lag 2); for lags from 0 to 6 days (OR = 1.08, 95% CI: 1.03–1.12, lag 3); for lags from 0 to 4 (OR = 1.06, 95% CI: 1.03–1.09, for lag 2 and 3). Conclusions The findings suggest the response to exposure to ambient ground-level ozone for skin and pharyngitis considered separately and jointly.

According to the World Health Organization (WHO), health is a state of complete phy-sical, psychological, social, and spiritual well-being that depends on a variety of factors. The biggest influence on maintaining the homeostasis of the human body has lifestyle (in 53%) and, next, the living environment (in 21%). Undoubtedly, factors such as air, water, soil, and living organisms in man's surroundings are equally important. The 19th and in particular the 20th century witnessed an intensive growth of in-dustry and transportation, crop intensification, and urbanization. These developments contributed to the unprecedented pollutant emissions. They have a detrimental influence on people's health and life. It is also estimated that air pollution alone is the cause of 1.4% of the total number of deaths. Furthermore, it leads to cardiovascular and respiratory diseases as well as nervous system disorders. According to the WHO, pollution is respon-sible for 30% of all cases of cancer. One othe most serious environemental problems in the contemporary world is smog over industrialized urban agglomerations. Accordingly, in the article, the authors present various factors detrimental to the environment and thus to human health.

Według Światowej Organizacji Zdrowia (WHO), zdrowie to stan pełnego, dobrego samopoczucia fizycznego, psychicznego, społecznego i duchowego. Zależy ono od bardzo wielu czynników. Największy wpływ na utrzymywanie homeostazy organizmu człowieka ma styl życia (53%), a następnie środowiska życia (21%). Niezwykle istotne są także czynniki środowiska naturalnego, takie jak: powietrze, woda, gleba oraz organizmy żywe otaczające człowieka. Wiek XIX, a szczególnie XX to czas bardzo intensywnego rozwoju przemysłu, transportu, intensyfikacji upraw rolnych, urbanizacji itp. Działania te doprowadziły do emisji do środowiska niespotykanych nigdy dotąd ilości zanieczyszczeń. Wpływają one negatywnie na zdrowie i życie ludzi. Szacuje się, że samo zanieczyszczenie powietrza jest przyczyną 1,4% całkowitej liczby zgonów. Ponadto, powoduje choroby układu krążenia, oddechowego, dolegliwości ze strony układu nerwowego. Według WHO zanieczyszczenia powodują 30% zapadalności na choroby nowotworowe. Ogromnym problemem dzisiejszego świata jest smog, który zalega nad uprzemysłowionymi aglomeracjami miejskimi. W artykule przedstawione zostały różnorodne czynniki, mające niekorzystny wpływ na środowisko, a przez nie na zdrowie człowieka.

The article presents the results of research aimed at determining the extent to which ozone used for disinfecting rooms affects the possibility of developing fingerprints on paper using the DFO method. A sudden increase in COVID-19 cases has placed the focus on disinfection techniques for user safety. It is also becoming important to ensure the safety of parcels addressed to various recipients by inactivating pathogens, while maintaining the possibility of examination that can identify the sender, which is important from the point of view of forensics. Ozonation is a disinfection technique that has been used for many years, in particular for water treatment or in the food industry. The experiments were carried out in rooms with a cubature of approx. 20 m3 using an ozone generator available on the market. The obtained ozone gas concentration did not exceed 10 ppm. The conducted research confirmed that the traces of fingerprints left on xerographic paper placed in a room subjected to ozonation in a concentration not exceeding 10 ppm are not damaged and can be successfully developed with the DFO method.

Obserwowany od początku 2020 r. gwałtowny wzrost zachorowań na COVID-19 wywołanych zakażeniem koronawirusem SARS-CoV-2 (ang. Severe acute respiratory syndrome coronavirus 2) oraz ogłoszenie w marcu ubiegłego roku przez WHO stanu pandemii spowodowały zwiększenie zainteresowania technikami dezynfekcji niszczącymi przede wszystkim wirusy. Jedną z takich metod jest ozonowanie. Niebezpieczeństwo zakażenia może wynikać z kontaktu materiału, np. przesyłki pocztowej, z nosicielem wirusa, szczególnie asymptomatycznym. Możliwe jest także intencjonalne skierowanie skażonego listu w celu wywołania zagrożenia. Wymusza to wypracowanie skutecznej metody dezynfekcji, która zapewni względne bezpieczeństwo odbiorcom. Jednocześnie aby umożliwić ewentualną identyfikację nadawcy, w tym m.in. na podstawie śladów daktyloskopijnych, niezwykle istotne jest stosowanie takich technik dezynfekcji, które nie zniszczą śladów kryminalistycznych. Ponadto, z punktu widzenia czynności wykrywczych, jest ważne ustalenie, czy ślady daktyloskopijne pozostawione na podłożu papierowym (np. list, koperta, dokument) poddanym ozonowaniu nie ulegają zniszczeniu.
