Research ArticleOpen accessIn the keywordsPotential Contribution of Traffic to Air Pollution in the State of KuwaitN. Al-Mutairi, P. KoushkiProblem statement: The reduction in ambient air pollution is a universal goal-particularly in urban areas, the lack of resources often necessitates identification and prioritization of sources of air pollutants. Efficient planning and effective management of environmental pollutants is thus important for optimum utilization of limited resources. Approach: This study examined seven years of data from three air pollution monitoring stations … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation Between Particulate Matter (PM10) Exposure and Cardiorespiratory Hospital Admissions: A Time Series AnalysisNur Nabila Abd Rahim, Abqariyah Yahya, Wan Rozita Wan MahiyuddinThis study aimed to evaluate the association between particulate matter (PM10) exposure and cardiorespiratory hospital admissions and develop a time series model for cardiorespiratory hospital admissions in Johor, Malaysia. Retrospective time series analysis was utilised to study cardiorespiratory hospital admissions for the study period 2015-2016. Over-dispersed Poisson generalized linear models with parametric smoothing functions were used to examine the association … …American Journal of Environmental Sciences, Vol. 17, Issue 2 · 27 May 2021 · 6,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatus of Air Quality with Potential Linkage to the Metrological Conditions in Three Major Cities of PakistanNaima Hamid, Muhammad Junaid, Syeda Maria Ali et al.Environmental pollution being fatal for all living organisms is growing adversely due to excessive industrialization and urbanization. Vehicular emissions have aggravated the situation and pose detrimental effects on human health. In this study, the trend of ambient air quality was analyzed in the three metropolitan cities of Pakistan, including Karachi, Lahore and Islamabad for a period of three years (2008-2010). … …American Journal of Environmental Sciences, Vol. 15, Issue 2 · 11 Mar 2019 · 8,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting Ozone Concentrations Using Box-Jenkins ARIMA Modeling in MalaysiaWan Rozita Wan Mahiyuddin, Nur Izzah Jamil, Zamtira Seman et al.Time series analysis and forecasting has become a major tool in many applications in air pollution and environmental management fields. Among the most effective approaches for analyzing time series data is the model introduced by Box and Jenkins. In this study, we used Box-Jenkins methodology to build Autoregressive Integrated Moving Average (ARIMA) model on the average of monthly ozone data … …American Journal of Environmental Sciences, Vol. 14, Issue 3 · 25 May 2018 · 8,943 accessesView PDFCite
Research ArticleOpen accessIn the abstractAIR POLLUTION AND CLIMATE CHANGE IN LAGOS, NIGERIA: NEEDS FOR PROACTIVE APPROACHES TO RISK MANAGEMENT AND ADAPTATIONAkinola A. Komolafe, Suleiman Abdul-Azeez Adegboyega, Adeleye Y.B. Anifowose et al.The significance of air pollution as one of the contemporary issues and accelerating factors that propel climate change in both developed and developing countries cannot be overemphasized. The problem of air pollution has seemingly become intractable with the incessant failure of both global and local environmental policies purportedly emplaced to address its devastating trend, particularly in growing megacities of the … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 12 Jul 2014 · 10,232 accessesView PDFCite
Research ArticleOpen accessIn the abstractHealth Impacts Estimation of Mineralogical and Chemical Characterization of Suspended Atmospheric Particles over the East DesertU. Ali Rahoma, Elsayed EmaraProblem statement: The small size fraction of aerosols, measured as PM10 and PM2.5, rather than the larger particles, is considered to be responsible for most of the health effects. Such particles have a relatively long residence time in the atmosphere and can therefore travel over long distances. Hence, a large portion of ambient concentrations of PM10 and in particular of … …American Journal of Infectious Diseases, Vol. 6, Issue 3 · 30 Sep 2010 · 10,772 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting and Time Series Analysis of Air Pollutants in Several Area of MalaysiaMohd Zamri Ibrahim, Roziah Zailan, Marzuki Ismail, Muhd Safiih LolaProblem statement: In keeping abreast with Malaysia’s rapid economic development and to meet the nation's aspiration for an improved quality of life, clean-air legislation limiting industrial and automobile emissions was adopted in 1978. Approach: Yet, to this day, air pollution from both sources still poses a problem for the nation. In order to predict the status of future air quality … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Assessment of Ambient Air Quality in Rabia Area for Years 2001 and 2004 in the State of KuwaitBader N. Al-Azmi, V. Nassehi, A. R. KhanThe hourly air pollutants concentrations were measured continuously by fixed ambient air stations located over the polyclinics in Rabia area in Capital Governorate in the State of Kuwait. The focus of this investigation is to determine the pollution levels of SO2, NO2 and O3 in year 2001 and 2004 to assess the pollution trends. The recorded data are used in … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview of Photochemical Smog Pollution in Jakarta Metropolitan, IndonesiaDollaris R. Suhadi, M. Awang, M. N. Hassan et al.An analysis of photochemical smog pollution in Jakarta was attempted using data from the existing air quality monitoring stations. Ground-level ozone potential is high in Jakarta due to the high traffic emissions of ozone precursors and the favorable surface meteorological conditions. Despite the frequent missing data during the 1996-1999 monitoring, which resulted in lower ozone values, ozone episodes were significantly … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,247 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordParsimonious Var Models For Air Pollution Dynamic AnalysisFontanella lara, Granturco mariagraziaWe discuss a framework to obtain temporal predictions for an evolving spatial field regularly sampled in time at arbitrary spatial locations. Difficulties caused by large data sets and the modelling of complicated spatio-temporal interactions limit the effectiveness of traditional space-time statistical models. In this study, we propose the use of a flexible approach to deal with large and small time-scale … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,181 accessesView PDFCite
