Introduction. Norilsk is annually both included into the Priority list of RF cities with the highest ambient air contamination and considered also among 12 large industrial centers where “Pure air” Federal project, an integral part of “Ecology” National project, is implemented. It is possible to assess whether targets fixed in a Federal project have been achieved only provided that there is a relevant system for assessing changes in ambient air quality parameters. To achieve that, experts created an information system for analyzing ambient air quality; among other data, the system used those obtained via social hygienic monitoring activities. Determining a list of chemicals that are priority factors causing inhalation risks is an integral part in finding solutions to this task.Material and methods. To solve tasks formulated in the research, we calculated comparative hazard indices for contaminants emitted by industrial enterprises in Norilsk; we also assessed sufficiency of programs for monitoring over ambient air quality taking into account results of dispersion calculations, results obtained via field observations performed by Federal Service for Hydrometeorology and Environmental Monitoring (Rosgidromet) and Federal Service for Oversight of Consumer Protection and Welfare (Rospotrebnadzor), and health risk assessments.Results. The assessment comparative hazard indices allowed creating a preliminary list of priority contaminants that included 18 substances. The list was specified and there were supplemented results obtained by analyzing data on aggregated dispersion calculations. Hygienic analysis of results obtained by field observations revealed substances that were priority ones as per their concentrations exceeding MPC and acceptable health risk levels. The final list included 19 chemicals that were recommended for monitoring over ambient air quality in Norilsk, including particulate matter PM10 and PM2.5.Conclusion. Further development of programs for monitoring the ambient air quality is among the most significant activities aimed at solving project tasks within “Pure air” Federal project and assessing achievements of project targets. Application of the methodology of health risk assessment allowed spotting out priority chemicals that were the most hazardous for people living in Norilsk; those chemicals were subject to obligatory control. The list included nitrogen oxide, nitrogen dioxide, benzene, particulate matter, PM10, PM2.5, phenol, hydrogen sulfide, cobalt oxide, copper (II) oxide (recalculated as per copper), nickel oxide (recalculated as per nickel), sulfur dioxide, and formaldehyde.

The present study examines the variation of ambient aerosol (PM10) concentrations in Karachi, city. Samples were collected from ten different locations, representative of urban background, residential, traffic and industrial areas from 2007 to 2011. At each location, PM10 was measured continuously from 08:00 am to 06:00 pm at local time. The maximum 10 h average particulate matter (PM10) mass concentrations were found at Tibet Centre (440.1mg/m3) and minimum at PCSIR Campus (21.7mg/m3) during 2008. A rising trend during 2008 may be due to the civil works for bridges and extension of roads at different locations in Karachi. The results also suggest that urban traffic and industrial areas appeared to have higher PM10 concentration than residential and background areas.

Air pollutant gas that has a real impact on the respiratory system is NO2 and SO2. Kalianak Surabaya is one of the areas with high traffic density more than 1.500 vehicles every hour. The most affected communities are the people living along the Kalianak highway. This study aims to analyze the ambient air (NO2 and SO2) in Kalianak and the risk of respiratory distress in the surrounding community. This research is descriptive, with cross sectional approach. The sample of this research is 19 respondents was done by purposive sampling. Spirometers were used to determine the status of lung function. The variables studied were age, length of stay, smoking habit, and Body Mass Index. The collected data were analized with environmental health risk assessment. Environmental Health Risk Assessment showed that the people living in this area unsafe with concentration of NO2 as measured. The results showed that more than 50% of respondents have respiratory problems (68,4%) with the mayority of respondenst aged 46-55 years old (31,6%), leght of stay >20 years (47,4%), non smokers (47,4%), and normal Body Mass Index (36,8%). The conclusion from this research is ambient air quality (NO2 and SO2) in Kalianak Surabaya still meet the quality standard, and the RQ>1 for NO2, it means that the risk level is unsafe. It is recommended that there is an efforts to control air pollution caused by motor vehicle activity by planting planst that can reduce ambient air pollutants.

Background: We aimed to provide information for health practitioners and other related people about the association between ambient air quality and adverse health outcomes in the general population of Nigde, a central Turkish city, within the context of current health data epidemiological evidence. Methods: The present study highlights the connection between health problems and time series of particulate matter (PM10) and sulphur dioxide (SO2) in Nigde, Turkey between 2011 and 2017. Significant morbidity is linked to ambient air pollution, resulting in a significant economic cost to society. Results: We found that the required funds to treat cancers and chronic obstructive pulmonary disease triggered by ambient air pollution in Nigde, exceed 9 million US dollars per year, even when only the city center is taken into account. Conclusion: As Turkish cities grow and urban population density increases, air pollution issues need to be given priority in order to protect the health of the public and support sustainable development for future generations. It is recommended that particulate matter concentration in this urban center should be significantly reduced to minimize health problems.

SARS-CoV-2 was discovered in Wuhan (Hubei) in late 2019 and covered the globe by March 2020. To prevent the spread of the SARS-CoV-2 outbreak, China imposed a countrywide lockdown that significantly improved the air quality. To investigate the collective effect of SARS-CoV-2 on air quality, we analyzed the ambient air quality in five provinces of northwest China (NWC): Shaanxi (SN), Xinjiang (XJ), Gansu (GS), Ningxia (NX) and Qinghai (QH), from January 2019 to December 2020. For this purpose, fine particulate matter (PM2.5), coarse particulate matter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), carbon monoxide (CO), and ozone (O3) were obtained from the China National Environmental Monitoring Center (CNEMC). In 2020, PM2.5, PM10, SO2, NO2, CO, and O3 improved by 2.72%, 5.31%, 7.93%, 8.40%, 8.47%, and 2.15%, respectively, as compared with 2019. The PM2.5 failed to comply in SN and XJ; PM10 failed to comply in SN, XJ, and NX with CAAQS Grade II standards (35 µg/m3, 70 µg/m3, annual mean). In a seasonal variation, all the pollutants experienced significant spatial and temporal distribution, e.g., highest in winter and lowest in summer, except O3. Moreover, the average air quality index (AQI) improved by 4.70%, with the highest improvement in SN followed by QH, GS, XJ, and NX. AQI improved in all seasons; significant improvement occurred in winter (December to February) and spring (March to May) when lockdowns, industrial closure etc. were at their peak. The proportion of air quality Class I improved by 32.14%, and the number of days with PM2.5, SO2, and NO2 as primary pollutants decreased while they increased for PM10, CO, and O3 in 2020. This study indicates a significant association between air quality improvement and the prevalence of SARS-CoV-2 in 2020.
