Temperature extremes and air pollution pose a significant threat to human health. A specific concern applies to heat events and elevated ground-level ozone concentrations, due to the physical relationships between these variables, the single and combined effects of both variables on human health and the anticipated substantial changes in the scope of climate change.The present contribution addresses relationships between air temperature and ground-level ozone, the association of these variables with atmospheric circulation patterns, the anticipated changes under future climate change as well as their association with human morbidity (i.e. myocardial infarction frequencies, Hertig et al. 2019) and mortality. The focus is on two climatically different regions in Europe, i.e., Bavaria (Central Europe) and Portugal (South Europe).In general, a strong relationship between air temperature and ozone formation became evident. Due to the non-linear nature of the relationship, higher temperatures usually led to substantially enhanced ozone concentrations. In the scope of climate change, considerable increases of maximum temperatures were assessed for Bavaria until the end of the century. Also, future ozone concentrations were projected to rise (Hertig 2020). With respect to spell-length related extremes (heat waves and/ or ozone pollution waves), heat waves were identified as the most frequent wave type for the two European regions under investigation. Waves were associated with in-situ built-up as well as with advection of air masses. Despite different climate settings, a comparable exposure to heat and ozone waves was found in Central and South Europe. In view of excess mortality, the most severe impacts were always associated with compound heat-ozone waves (Hertig et al. 2020).Research was supported by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under project number 408057478.Hertig, E., Russo, A., Trigo, R.

Earth's atmosphere is made of two gases Nitrogen and Oxygen. Five major air pollutants are Ground level Ozone, Airborne particles or aerosols, Carbon monoxide, Sulfur dioxide, Nitrogen dioxide. Air pollutants risky to human health are Ground level Ozone and Aerosols. They are the main ingredients of Smog . The ground level ozone is formed when sunlight reacts with certain chemical emissions like nitrogen dioxide, carbon monoxide or methane These chemicals are emitted from industrial waste, car exhaust, gasoline vapors etc. Air quality is measured with the Air Quality Index. An AQI under 50 is considered as good air quality however as the AQI number increases , it becomes a concern for human health . Researcher measured the PM level (PM 2.5 and PM 10), temperature, Humidity and other related parameters continuously on different woods in different times in a fixed size room and constrained environment to establish that Yagya is a reliable source to reduce environment pollution .

Temperature extremes like hot days or prolonged episodes of high air temperature like heat waves can cause adverse human health effects. Heat-related mortality only represents the extreme end of a variety of possible health outcomes like heat exhaustion or heat stroke.Exposure to ground-level ozone provokes negative impacts on human health primarily affecting the cardio-pulmonary system causing respiratory or cardiovascular diseases. These diseases include, but are not limited to, lung inflammation and tissue damage, asthma, heart attacks or heart failure.High levels of ozone and temperature often coincide due to the underlying ozone formation characteristics. As synergistic effects lead to a risk beyond the sum of their individual effects, the co-occurrence of elevated levels of air temperature and ground-level ozone concentrations represents an even intensified human health risk.The current contribution deals with statistical models and analysis of the interplay between large-scale meteorological and synoptic conditions, prevailing air pollution levels and combined ozone and temperature events under present and future climatic conditions. In this context, meteorological mechanisms representing main drivers of these concurrent ozone and temperature events were identified. Large-scale atmospheric circulation dynamics and their relationships with ground-level ozone and temperature conditions were evaluated.The methodological focus was primary on statistical modeling approaches and different machine learning methods. Self-Organizing Maps, an artificial neural network algorithm based on unsupervised machine learning, were used to classify synoptic types based on daily mean sea level pressure reanalysis data. The resulting synoptic types were evaluated with regard to the European ozone and temperature characteristics in order to identify types associated with high ozone and temperature. Regression analyses with e.g. shrinking methods were used to identify main predictors for concurrent ozone and temperature events. Due to data availability and research foci, two varying time windows from 1993 to 2012 as well as from 2004 to 2018 were used within the study. The European area built the regional focus.Anthropogenic-induced global climate change affects not only mean but also extreme temperatures as well as associated ground-level ozone concentrations due to changing synoptic circulation and chemical environment conditions. Future frequency changes of concurrent ozone and temperature events were evaluated exemplarily for Central Europe. Statistical downscaling projections until the end of the twenty-first century were assessed by using the output of seven models of the Coupled Model Intercomparison Project Phase 5 (CMIP5). A sharp increase was projected under RCP4.5 and RCP8.5 scenario assumptions. Respective multi-model mean changes amounted to 8.94% and 16.84% as well as 13.33% and 37.52% for mid- (2031&#8211;2050) and late-century (2081&#8211;2100) European climate, respectively (Jahn and Hertig 2020). Hotspot regions with more frequent occurrences of these combined events in Central Europe were identified for which, due to their associated individual and combined health effects, a higher future vulnerability can be expected.

Earth's atmosphere is mainly made up of two gases, nitrogen and oxygen, which together comprise 99% of gases therein. The other gases include the remaining 1% of the atmosphere. Amongst these are the five major air pollutants (e.g., ground-level ozone, airborne particles or aerosols, carbon monoxide, sulfur dioxide, nitrogen dioxide). Excess of these pollutants in the atmosphere is risky to human health. They are the main ingredients of smog. Air quality is measured with the air quality index. An AQI under 50 is considered as good air quality; however, as the AQI number increases, it becomes a concern for human health. To find a non-conventional solution to air pollution problem, it has been proposed to do Yagya, a fire process with three different samidhas, namely mango wood, bargad wood, and dry cow dung sticks and study their relative emissions and ability to reduce the aerosols PM 2.5 and PM 10. In this paper, the researcher has measured the PM levels (PM 2.5 and PM 10) and carbon dioxide CO2 along with AQI, temperature, and humidity.
