PM10 levels of the mineral components Si, Al, Fe, Ca, Mg and some trace metals were measured at three different sites in the urban area of Vienna (Austria). Observed trace metal concentrations varied between less than 0.1 ngm 3 (Cd) and approximately 200 ngm 3 (Zn), mineral components showed enhanced concentrations ranging from 0.01 mgm 3 (Ca) to 16.3 mgm 3 (Si). The contribution of the respect...

BACKGROUND Ischemic heart disease (IHD) is a major public health concern. Although many epidemiologic studies have reported evidence of adverse effects of particulate matter (PM) mass on IHD, significant knowledge gaps remain regarding the potential impacts of different PM sources. Much the same as PM size, PM sources may influence toxicological characteristics. OBJECTIVES We identified contr...

OBJECTIVES In order to assess if ambient air pollution in urban areas could be related to alterations in male/female ratio this study objectives to evaluate changes in ambient particulate matter (PM10) concentrations after implementation of pollution control programmes in São Paulo city and the secondary sex ratio (SRR). DESIGN AND METHODS A time series study was conducted. São Paulo's distri...

The estimation of ambient particulate matter with diameter less than 10 μm (PM10) at high spatial resolution is currently quite limited in China. In order to make the distribution of PM10 more accessible to relevant departments and scientific research institutions, a semi-physical geographically weighted regression (GWR) model was established in this study to estimate nationwide mass concentrat...

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 ...

BACKGROUND Exposure to air pollution in the form of particulate matter smaller than 10 μm in diameter (PM10) has been associated with increased morbidity and mortality. However, since air pollution is correlated with confounding factors that might otherwise affect health, identifying the causal link has proven challenging. OBJECTIVES To identify the effect of PM10 on hospital admissions due t...

BACKGROUND Asian sand dust (ASD) that originates in the Mongolian Desert in the spring induces serious respiratory health problems throughout East Asia (China, Korea, Japan). PM10 (particulate matter with an aerodynamic diameter <10 μm) is a major air pollutant component in ASD. We studied the effects of PM10 on allergy symptoms in patients with allergic rhinitis during the spring season, when ...

In this study the gap between the two exceedances is analyzed using time series analysis. The time series of PM10 (particulate matter of size less than 10 micron) observed during 2005–2013 in two cities; Nagpur and Chandrapur in central India is considered. Higher PM10 concentration is observed in Chandrapur as compared to Nagpur. Exponential relationship is observed between the average time be...
