This presentation will discuss the efforts of the Utah Division of Air Quality (DAQ) and the Utah Automated Geographic Reference Center (AGRC) to provide public "near real time" air quality maps utilizing ArcIMS and ArcSDE. DAQ currently operates approximately 30 air quality monitoring stations in Utah's urban areas that collect data on a variety of air pollutants. Through a U.S. EPA EMPACT Gra...

background: since the industrial revolution, the rate of industrialization and urbanization has increased dramatically. regarding this issue, specific regions mostly located in developing countries have been confronted with serious problems, particularly environmental problems among which air pollution is of high importance. methods: eleven parameters, including co, so 2 , pm 10 , pm 2.5 , o 3 ...

The paper presents a study aimed at investigating the indoor air quality (IAQ) and people’s perception regarding environment of schools public buildings in Timisoara. monitoring was performed during cold season, period January 2020 – February 2021. Six administrative edifices belonging to municipality were subject monitoring. An Andersen microbial sampler used enumerate numbers different kinds ...

Air pollution has become a severe environmental problem due to urbanization and heavy traffic. Monitoring street-level air quality is an important issue, but most official monitoring stations are installed to monitor large-scale air quality conditions, and their limited spatial resolution cannot reflect the detailed variations in air quality that may be induced by traffic jams. By deploying wir...

Crowdsensing of air quality is a useful way to improve public awareness and supplement local air quality monitoring data. However, current air quality monitoring approaches are either too sophisticated, costly or bulky to be used effectively by the mass. In this paper, we describe AirTick, a mobile app that can turn any camera enabled smart mobile device into an air quality sensor, thereby enab...

Indoor air quality is a very important parameter for living environments, which is closely related to people's daily work and health. However, nowadays, the environmental pollution, haze weather and other issues have become increasingly prominent. In this context, it is necessary to design an automatic detection device for monitoring the air quality in buildings. In this paper, an indoor air qu...

Assessment of air quality has been traditionally conducted by ground based monitoring, and more recently by manned aircrafts and satellites. However, performing fast, comprehensive data collection near pollution sources is not always feasible due to the complexity of sites, moving sources or physical barriers. Small Unmanned Aerial Vehicles (UAVs) equipped with different sensors have been intro...

in recent years, increasing population, vehicles and industrial growth have caused air pollution that is initiated many environment problems and damaged public health. to check the air quality in different regions, pollution data that are collected in air pollution stations are required. for better and more realistic monitoring of air pollution, the stations must be distributed exactly and even...

Overall, this is a good example of a case study, with relevance specifically to Colorado air quality and which, more generally, speaks to air quality concerns relevant to the western United States, where wildfires are a substantive air quality issue. In Colorado, there is an active community of regulators at the State and Federal level who have been debating the very issues discussed in this pa...

background : dental unit waterlines (duwls) are ideal nvironment for development of microbial biofilms. microbial contamination of water in duwls is thought to be the result of biofilm formation as it could serves as a haven for pathogens. the aim of this study was to assess microbial quality of water in dental unit waterlines of dental units located at the dental school of isfahan university o...
