Air quality monitoring by using bio-indicator currently being promoted and frequently used in studies due to their advantages compared other scientific approaches. The of as a bio-monitoring air are, it remains the cheapest, most available simplest matrix for reliable atmospheric monitoring. This study was conducted determine moss ability be when expose different environments. Four environmenta...

Air pollution is one of the emerging environmental issues of the western cities of Iran. Daily data (2009-2012) on air pollutants in Sanandaj, Iran, were collected from the Department of Environmental Protection, Kurdistan Province, Iran. Climatic parameters were collected from the Kurdistan Meteorological Bureau. The quality of air was assessed based on the air quality index (AQI). The relatio...

The impact of global air pollution on climate and the environment is a new focus in atmospheric science. Intercontinental transport and hemispheric air pollution by ozone jeopardize agricultural and natural ecosystems worldwide and have a strong effect on climate. Aerosols, which are spread globally but have a strong regional imbalance, change global climate through their direct and indirect ef...

2 Aircraft cabin ventilation In early commercial jet aircraft, passenger cabins were ventilated with 100% outside air. In more recent jet aircraft, approximately 50% of the ventilation air is outside air and the remaining 50% is filtered recirculated cabinair. This development has allowed for fuel savings as well as a supposed improvement in the relative humidity of cabin air. With typical pass...

On November 24, 1993, the US Environmental Protection Agency adopted the transportation conformity rule, pursuant to Section 176(c)(4) of the Clean Air Act. The conformity rule requires that transportation plans, programs and projects funded or approved by the federal government or their agents under Title 23 (Highways) U.S.C. or the Federal Transit Act conform with state or Federal air quality...

In the last few decades, Indoor Air Quality (IAQ) has received increasing attention from the international scientific community, political institutions, and environmental governances for improving the comfort, health, and wellbeing of building occupants.[...].

Introduction Lake Tahoe resides in a high elevation basin separated from the Sacramento Valley by the dominant Sierra Nevada divide along the Crystal Range. Lower ridges of the Carson Range to the east separate the lake from the Great Basin. These physical attributes define atmospheric processes in the Tahoe basin as much as define hydrological processes. The presence of the cold lake at the bo...

Systematic collection of long term mesoto large-scale datasets of ambient air quality provides an indispensible means for air pollution monitoring. However, the quality of these monitoring data depends on the chosen method of measurements and the QA/QC procedures applied. We present a consolidated screening tool for the automatic detection of outliers in large data volume air quality monitoring...
