Air quality, like weather, can affect everyone, but responses differ depending on the sensitivity and health condition of a given individual. To help protect exposed populations, many countries have put in place real-time air quality nowcasting and forecasting capabilities. We present in this paper an optimal combination of air quality measurements and model outputs and show that it leads to si...

The Air Quality Index (AQI) is an evaluating indicator for the atmospheric environment released by various environmental monitoring centers to communicate the present air quality status to the public, which is calculated by the aid of the monitored concentrations of six common air pollutants and relevant computational formulae. Considering that the historical data of daily overall AQI illustrat...

Bioaerosols are a major source of pollution in indoor environments, where people spend approximately 90% their time, and the microorganisms adhered to PM2.5 adversely affect human health. However, most research has focused on concentration these aerosols factors that influence it rather than correlation between microbial activity air quality. Thus, this study used modified technique fluorescein...

ABSTRACT: Smoke haze related to biomass burning is a recurring environmental problem in Southeast Asia which has affected air quality not only in the source regions, but also in the surrounding areas. Air quality monitoring stations and meteorological stations in the region provide valuable information on the concentrations of criteria pollutants such as sulphur dioxide, nitrogen oxide, carbon ...

The growing concern about Indoor Air-Quality has accelerated the development of small, low-cost air-quality monitoring systems. These systems are capable of monitoring various indoor air pollutants in real time, notifying users about the current air-quality status and gathering the information to the central server. However, most Internet of Things (IoT)-based air-quality monitoring systems num...

BACKGROUND The air quality index (AQI) is widely used to characterize the quality of ambient air. Chinese cities officially report the AQI on a daily basis. To assess the possible effects of air pollution on daily outpatient visits, we examined the association between AQI and the daily outpatient count. METHODS Daily data on outpatient visits to each clinical department were collected from th...

The Bureau of Labor Statistics (BLS) is developing a Computer-Assisted Data Collection (CADC) instrument for the Commodities and Services (C&S) survey for the Consumer Price Index (CPI). The instrument must be flexible enough to handle a variety of procedures and situations, but it must also be logical and useful for the data collectors and provide tools to help to ensure data quality. Therefor...

OBJECTIVE To inform family physicians about the health effects of air pollution and to provide an approach to counseling vulnerable patients in order to reduce exposure. SOURCES OF INFORMATION MEDLINE was searched using terms relevant to air pollution and its adverse effects. We reviewed English-language articles published from January 2008 to December 2009. Most studies provided level II evi...

Background: Despite improvements, air pollution still remains a major public health issue. Numerous epidemiological studies have demonstrated the adverse health effects of air pollution exposure based on modeled measures, but only a few have considered the health impact of perceived air quality. Improving our knowledge of individual perceptions is crucial to defining targeted actions and promot...
