Measurements were carried out to determine the PM2.5, PM10 and, CO2 levels in schools located urban areas of Imphal, Manipur. The particulate matters (PM2.5 and PM10) monitored gravimetrically with standardised samplers, while air was measured by gas chromatography. Average PM2.5 concentration classrooms 41.0 ± 9.0 µg/m3 79.4 20.2 µg/m3, respectively, it comparatively higher than outdoor 34.8 8...
background & aims of the study: recent studies indicated that particulate matter can have the lung irritation, chronic lung diseases, lung tissue, etc. the aim objective of this study was to assess the mortality associated with exposure to pm10 concentrations in ilam, iran, during 2013. materials & methods: pm10 data were taken from ilam's local agency of environment (i-lae). the annual mo...
conclusions to reduce the impacts of particulate matter on health status of people in ilam, necessary training by health systems should be conducted for people, especially those with chronic lung and heart diseases, the elderly and children to reduce their activities on the dusty days. methods pm10 data was taken from the ilam environmental protection agency. the annual morbidity including hosp...
The estimation of pollution fields, especially in densely populated areas, is an important application in the field of environmental science due to the significant effects of air pollution on public health. In this paper, we investigate the spatial distribution of three air pollutants in Tehran’s atmosphere: carbon monoxide (CO), nitrogen dioxide (NO2), and atmospheric particulate matters less ...
Numerous studies have shown associations between air pollution and health effects on human. The aims of the present study were to provide quantitative data on variation of atmospheric particulate matter (PM) concentration and the impact of PM on the health of people living in Tabriz city. The approach proposed by the World Health Organization (WHO) was applied using the AirQ 2.2.3 software deve...
since particulate matter (total suspended particles and particulate matter with median aerodynamic diameter less than 10 µm) is one of the important pollutants in the ambient air of tehran, the capital of iran, organic substances, inorganic substances and lead levels in tsp and pm10, correlation between tsp and pm10 concentrations, ratio among the two fractions and relation between tsp and pm10...
BACKGROUND We report on a novel approach to the analysis of suspended particulate data in a rural setting in southern Ontario. Analyses of suspended particulate matter and associated air quality standards have conventionally focussed on 24-hour mean levels of total suspended particulates (TSP) and particulate matter <10 microns, <2.5 microns and <1 micron in diameter (PM10, PM2.5, PM1, respecti...
PM10 (the mass of particles present in the air having a 50% cutoff for particles with an aerodynamic diameter of 10 microm) is the standard measure of particulate air pollution used worldwide. Epidemiological studies suggest that asthma symptoms can be worsened by increases in the levels of PM10. Epidemiological evidence at present indicates that PM10 increases do not raise the chances of initi...
The paper describes a MAS (multi-agent system) simulation approach for controlling PM10 (Particulate Matter) crisis peaks. A dispersion model is used with an Artificial Neural Network (ANN) to predict the PM10 concentration level. The dispersion and ANN models are integrated into a MAS system. PM10 source controllers are modelled as software agents. The MAS is composed of agents that cooperate ...
Evidence for a role of long-term particulate matter exposure on acute respiratory infections is growing. However, which components of particulate matter may be causative remains largely unknown. We assessed associations between eight particulate matter elements and early-life pneumonia in seven birth cohort studies (N total=15,980): BAMSE (Sweden), GASPII (Italy), GINIplus and LISAplus (Germany...
