This study aimed to determine the cement industry's impact on ambient air quality inside and around a Saudi Arabian cement plant. Air quality has assessed in terms of several indicators: carbon dioxide, carbon monoxide, nitrogen dioxide, sulfur dioxide, PM10, PM2.5, ozone, and volatile organic compounds. AERMOD model was used to predict the concentrations of pollutants in the surrounding area. Results obtained revealed that the concentration of all impurities is within the standard limits for ambient air quality. In comparison with OSHA guidelines, only PM10 concentration exceeded the allowable limit. The higher concentrations of pollutants are recorded at the site closest to the plant site (S1, a housing compound located 0.8km ESE from the plant). Concentrations at the other monitoring sites decreased significantly. Except for PM10, the calculated hazard quotient (HQ) of all pollutants was <1which indicated no health effects are expected. The HQ of emissions can be ranked as: PM10> PM2.5>CO2>O3>CO>VOCs>NOx>SO2>H2S. The hazardous index (HI) was: 3.59, 2.76, 2.18, and 2.67 for S1, S2 (located 17km NNE), S3 (located 10.6km SE), and S4 (located 6.4km SSW), respectively. The affected organs can be ranked based on health risk calculation as respiratory system>cardiovascular system>Eye irritation>Allergy infection>Nervous system>Development>Hematology >Alimentary endocrine. The cancer risk factor was shallow and ranged from 4.04x10-6 for S4 to 1.88x10-5 for S1, which indicated a very low-risk potential. In terms of emissions concentrations, AERMOD predicted higher concentrations than the actual monitoring data for all measured parameters.

Backgrounds: A cement industry is one of anthropogenic sources of air pollution. In polluting the air, the industry creates some dust particles, nitrogen oxide (NO2), sulfur oxide (SO2), and carbon monoxide (CO).Research Purpose: The research aims at finding out the ambient air quality around a cement industry and relating it with the lung capacity of people living around the area.Methodology: This research uses cross sectional studies by measuring the ambient air quality in the morning, noon, and evening in four different settlements within 3 km from the cement industry. The measurement is then correlated with the FEV1 and FVC of lung capacity of people living around the area.Result: Of all four locations, three have ambient air quality (PM2.5 = 109.47 µg/Nm3, TSP = 454.7 µg/Nm3) that surpass the quality standard (PM2.5 = 65 µg/Nm3, TSP = 230 µg/Nm3). Of 241 respondents, the average level of FVC and FEV1 is respectively 1.9352 liter (SD: 0.45578) and 1.7486 liter (SD: 0.43874). Furthermore, the level of PM2.5 in the morning and at noon is respectively p=0.009 and p=0.003; the level of TSP in the morning and at noon is respectively p=0.003 and p=0.01; the level of NO2 in the morning is p=0.006; the level of SO2 in the morning, at noon and in the evening is respectively p=0.000, p=0.022, and p=0.000; and the level of CO in the morning, at noon and in the evening is respectively p=0.003, p=0.015, and p=0.024. Those levels are associated with the level of respondents’ FEV1. Moreover, the level of TSP in the morning is p=0.024; the level of SO2 in the morning and in the evening is p=0.007. These levels relate to the level of respondents’ FVC.Keywords: FVC, FEV1, CO, NO2, SO2, TSP, PM2.5, cement industry.

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.

The first two years of «Clean air» Federal project in Omsk have been completed and preliminary results have been estimated. The present work deals with issues related to implementation of the Complex program aimed at reducing emissions, highlights the sanitary-epidemiologic situation related to air contamination in settlements, and describes activities aimed at optimizing a laboratory network used for monitoring over ambient air quality. It is essential to obtain maximum objective data on population health risks caused by ambient air contamination at the initial stage of the Federal project implementation. Our research goal was to estimate intermediate results in the Federal project implementation taking into account preliminary analysis of sanitary epidemiologic welfare in Omsk related to ambient air contamination. Our research object was ambient air quality in Omsk, potential health risks and population health parameters associated with ambient air contamination over 2009–2019. The examination was performed in accordance with a procedure for health risk assessment under exposure to chemicals (R 2.1.10.1920-04), as well as procedures, approaches, and algorithms stipulated in the normative and methodological documents MR 2.1.6.0158-19, MR 2.1.6.0156-19, with use of geoinformation technologies and statistical procedures. The research allowed substantiating a program for monitoring over ambient air quality taking into account all the existing monitoring systems basing on spatial distribution of total hazard quotient (S) in Omsk residential area and preliminary data obtained via aggregated calculations of ground contaminants concentrations. We suggested a list of control parameters and a procedure for their estimation in order to provide objective and timely monitoring over implementation of the Complex program aimed at reducing emissions into ambient air in Omsk. Implementation of the Complex program was estimated as per results of certain activities accomplished within it in 2019.

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.
