The aim of the work is to assess the contribution of emissions from forest fires to air pollution using the example of the territory of the Pribaikalsky National park. To achieve this goal, calculations of gross emissions were carried out based on forestry data on fires. With the help of the program complex «Ecologist» calculations of concentrations of impurities emitted into the atmosphere during forest fires were carried out. Based on the results of the calculations, maps of the concentrations of pollutants released into the atmosphere from fires were created. The analysis of the received results obtained allowed us to conclude that the established sanitary and hygienic standards were exceeded. Among the considered list of emissions, the maximum concentrations of acrolein, carbon monoxide, acetone, and nitrogen dioxide were revealed. The areas located in the zone of increased atmospheric pollution created by fires on the territory of the forestries of the Pribaikalsky National park were identified.

Respiration requires the free passage of air through the nasopharyngeal duct. The obstruction of the respiratory canal may cause growth and development anomalies in young patients. Atmospheric pollution in urban areas increases respiratory allergies such as allergic rhinitis in the population. This research analyzed the relation between the variation in atmospheric pollution and allergic rhinitis with the incidence of posterior and anterior crossbite in the Metropolitan Area of Monterrey. Patients between 5 to 16 years old were diagnosed with chronic allergic rhinitis. Patients were given dental exams to identify the presence of crossbite in the patients. The geographical location of their homes and concentration variation of ozone, PM2.5, PM10 and sulphur dioxide in three-year periods from 2004-2014 was analyzed using mapping techniques to establish if the increasing pollution concentrations are related to the presence of crossbite in patients with allergic rhinitis. In general, an increase in pollutant concentrations resulted in a significant increase of crossbite in patients. In conclusion, the increasing concentrations of air pollution and respiratory diseases are related to craniofacial growth and development anomalies.

Actively caring for the environment is an issue that prevails in the international debate, and our country takes part on this argument. One aspect of environmental deterioration is, with no doubt, atmospheric pollution; a constant in modern societies, which, in the attempt to find growth and development, impact the natural and urban environment they inhabit. A distinctive feature of commercial and economic exchange are the strategic cities, so-called capitals, in addition to the territories where coastal tourism predominates as an engine of regional human development. In this balance, which is far from being sustainable and fair, an exponential consumer market dominates and generates the progressive increase in the use of fossil fuels. The former being emitted into the atmosphere, in such a way that they alter chemical composition and cause harmful air quality. In addition, the territory is impacted, intoxicating the soil and water, which are the final deposit. The objective of this work is to determine the temporal behavior of atmospheric pollutants in the city of Tepic, Nayarit, Mexico and to identify the dominant pollution indicators considering the international and national context. Through the statistical analysis of the databases of particles smaller than 2.5 micrometers, particles smaller than 10 micrometers and carbon monoxide, the behaviors of these pollutants in the study area were obtained. Among the most significant results, particles smaller than 2.5 micrometers showed maximum levels outside the norm almost all year round, with values ​​reaching 170 micrograms per cubic meter. On the other hand, the particles smaller than 10 micrometers presented satisfactory levels in their average behavior; however, the maximum concentrations remained outside the official Mexican standard. Regarding the analysis of CO, a behavior within the maximum permissible limits of protection for the population was reported; Nevertheless, by favoring the formation of tropospheric ozone, its contribution is significant, especially when the atmosphere is highly photo-reactive. This research can be used as a timely tool for mitigation of climate change, where the results contribute to the review and rethinking of public management of the environment towards sustainable development.
