Air pollution in cities is a severe and worrying problem because it causes threats to economic development health. Furthermore, with the of industry technology, rapid population growth, massive expansion cities, total amount emissions continue increase. Hence, observing predicting air quality index (AQI), which measures fatal pollutants humans, has become more critical recent years. However, th...
Sensor networks are currently an active research area mainly due to the potential of their applications. In this paper we investigate the use of Wireless Sensor Networks (WSN) for air pollution monitoring in Mauritius. With the fast growing industrial activities on the island, the problem of air pollution is becoming a major concern for the health of the population. We proposed an innovative sy...
Air pollution is found to have significant association with living health all over global world. Environment Protection Department of Punjab, Pakistan provides the monthly air quality index (AQI) data on concentrated particulates like PM2.5, PM10, NO2, SO2 and O3. concentrations may vary season, regional geography climate. We performed blood sampling 45 dogs from different breeds (Labrador retr...
Identifying the particulate matter (PM) sources is an essential step to assess PM effects on human health and understand PM’s behavior in a specific environment. Information about composition of organic or/and inorganic fraction usually used for source apportionment studies. In this study that took place Dakar, Senegal, identification two fractions was performed by utilizing data elemental carb...
Background: Risk factors of non-communicable disease (NCD) origin from early life, and exposure to environmental pollutant may be a predisposing factor. This study aimed to investigate the association of air quality index (AQI) and fine particulate matter (PM2.5) with some NCD risk factors in a sample of Iranian children and adolescents. Materials and Methods: This cross-sectional study was con...
مقدمه: یکی از مهمترین مسائل زیست محیطی در جهان از جمله ایران، بویژه در کلان شهرها، مشکل آلودگی هوا است. آلودگی هوا یک ریسک فاکتور مهم محیطی در مقابل سلامت عمومی محسوب میشود. هدف کلی از مطالعه حاضرتعیین ارتباط بین کیفیت هوا و میزان وقوع انفارکتوس حاد قلبی در شهر تهران میباشد. روش کار: در این مطالعه از نوع مورد- متقاطع است، ارتباط بین ) AQI: Air Quality Index ( با انفارکتوس حاد قلبی از نوع ST...
Crop residue burning produces a lot of polluting gases and fine particles, endangering human health, damaging soil structure, causing fire accidents. In addition to the impact on local environment, pollutants can spread with wind more distant areas their air quality. Nevertheless, comparative analysis two common parameters, number points, burned area urban quality indicators has not been report...
Purpose Air quality and its assessment in urban areas has become a necessity. This is attributed to the increasing air pollution landscape from anthropogenic activities necessary for economic growth development. study investigates potential health risk posed nitrogen dioxide (NO 2 ) residents of low town Mohammedia city, Morocco. Design/methodology/approach The NO concentration was measured on ...
Forest fires lead to severe damage the environment and human health. Monitoring can be applied using remotely sensed data in combination with Geographical Information Systems (GIS) based spatial analysis. Lately, Iraq subjected many forest fires. In this study, aim was monitor detect burned areas Mosul Park during latest period which happened June 2022. The hypothesis of study on Sentinel-2 ima...
Previous studies have estimated the influence of control measures on air quality in ecological environment during COVID-19 pandemic. However, few attached importance to comparative study several different periods and evaluated health benefits PM 2.5 decrease caused by COVID-19. Therefore, we aimed estimate measures' impact pollutants 16 urban areas Beijing conducted a across three establishing ...
