Concentration Levels

Air quality monitoring on the territory of AP Vojvodina was initiated in mid 90s. During the last decade of the 20th century the development of the air quality monitoring in Serbia didn?t keep up with the pace of the other countries in the region due to political isolation and severe economic crisis. Monitoring of the particular pollutants was conducted unsystematically and sporadically. Data presented in this paper were obtained on the territory of the city of Zrenjanin, which represents typical agglomeration in the region in regard to its geographical location, population, level of industry development and the presence of natural gas as energy product in the remote and domestic heating system of residential objects. Available data on the concentration levels of PM10 (particulate matter with aerodynamic diameter less than 10 ?m), TSP (total suspended particulates) and BS (black smoke) during the period of 2005-2007 (three cold and three warm seasons) have been used in this work in order to carry out analysis and comparison of the daily concentration levels of PM10, TSP and BS and their seasonal variation.

Abstract. China has been experiencing severe air pollution in recent decades. Although ambient air quality monitoring network for criteria pollutants has been constructed in over 100 cities since 2013 in China, the temporal and spatial characteristics of some important pollutants, such as particulate matter (PM) components, remain unknown, limiting further studies investigating potential air pollution control strategies to improve air quality and associating human health outcomes with air pollution exposure. In this study, a yearlong (2013) air quality simulation using the Weather Research & Forecasting model (WRF) and the Community Multi-scale Air Quality model (CMAQ) was conducted to provide detailed temporal and spatial information of ozone (O3), PM2.5 total and chemical components. Multi-resolution Emission Inventory for China (MEIC) was used for anthropogenic emissions and observation data obtained from the national air quality monitoring network were collected to validate model performance. The model successfully reproduces the O3 and PM2.5 concentrations at most cities for most months, with model performance statistics meeting the performance criteria. However, over-prediction of O3 generally occurs at low concentration range while under-prediction of PM2.5 happens at low concentration range in summer. Spatially, the model has better performance in Southern China than in Northern, Central and Sichuan basin. Strong seasonal variations of PM2.5 exist and wind speed and direction play important roles in high PM2.5 events. Secondary components have more boarder distribution than primary components. Sulfate (SO42−), nitrate (NO3−), ammonium (NH4+), and primary organic aerosol (POA) are the most important PM2.5 components. All components have the highest concentrations in winter except secondary organic aerosol (SOA). This study proves the ability of CMAQ model in reproducing severe air pollution in China, identifies the directions where improvements are needed, and provides information for human exposure to multiple pollutants for assessing health effects.

The concerns related to particulate matter’s health effects alongside the increasing demands from citizens for more participatory, timely, and diffused air quality monitoring actions have resulted in increasing scientific and industrial interest in low-cost particulate matter sensors (LCPMS). In the present paper, we discuss 50 LCPMS models, a number that is particularly meaningful when compared to the much smaller number of models described in other recent reviews on the same topic. After illustrating the basic definitions related to particulate matter (PM) and its measurements according to international regulations, the device’s operating principle is presented, focusing on a discussion of the several characterization methodologies proposed by various research groups, both in the lab and in the field, along with their possible limitations. We present an extensive review of the LCPMS currently available on the market, their electronic characteristics, and their applications in published literature and from specific tests. Most of the reviewed LCPMS can accurately monitor PM changes in the environment and exhibit good performances with accuracy that, in some conditions, can reach R2 values up to 0.99. However, such results strongly depend on whether the device is calibrated or not (using a reference method) in the operative environment; if not, R2 values lower than 0.5 are observed.

The City

The air quality monitoring system in industrial cities is one of the systems for responding to risk factors in the public health system. The purpose of the study is, on the basis of a hygienic assessment of carcinogenic and non-carcinogenic risks from exposure to specific pollutants in the cities of Dnipro, Kamenskoye, Kryvyi Rih, to substantiate a program for regional monitoring of atmospheric air quality. Materials and methods. To achieve this goal, the results of air quality studies in the largest industrial cities of the Dnipropetrovsk region – Dnipro, Kryvyi Rih and Kamenskoe for the period 2005-2019 were analyzed in terms of phenol, formaldehyde, benzene, xylene and toluene, and carcinogenic and non-carcinogenic risks to public health were calculated in these cities. Results and discussion. According to the results of the study, individual carcinogenic risks in all three cities in terms of formaldehyde are medium, and in terms of benzene are high. The population carcinogenic risk ranges from 200-269 additional cases of cancer from exposure to formaldehyde and 3727-4426 additional cases of cancer from chronic inhalation exposure to benzene. The calculation of non-carcinogenic risks identified the priority specific air pollutants in the cities under study, as well as the main target organs. So the main systems that are influenced by the action of the studied chemicals are the central nervous system, the general development of the body and the blood system. Based on the risk assessment, it was established that it is necessary to include the Kamenskoye metro station for regional monitoring. It is necessary to include all pollutants from List A to the minimum list of investigated chemicals, and for the city of Dnipro and Kamenskoye it is additionally necessary to carry out studies of phenol, formaldehyde and toluene and in the city of Kryvyi Rih – formaldehyde and toluene. The mechanism of data processing and interaction between the subjects of monitoring has been substantiated for the timely identification of risks and the development of necessary preventive measures for risk management. Conclusion. It was found that carcinogenic and non-carcinogenic risks in industrial cities of the Dnipropetrovsk region are not acceptable. The existing monitoring system does not fully comply with the current requirements. The minimum program of the regional air quality monitoring system in the Dnipropetrovsk region has been scientifically substantiated
