Urban BTEX Spatiotemporal Exposure Assessment by Chemometric Expertise
Normative regulations on benzene in fuels and urban management strategies are expected to improve air quality. The present study deals with the application of self-organizing maps (SOMs) in order to explore the spatiotemporal variations of benzene, toluene, ethylbenzene, and xylene levels in an urban atmosphere. Temperature, wind speed, and concentration values of these four volatile organic co...
متن کاملAssessment of the BTEX concentrations and health risk in urban nursery schools in Gliwice, Poland
Indoor air quality (IAQ) in nursery school is believed to be different from elementary school. Moreover, younger children are more vulnerable to air pollution than higher grade children because they spend more time indoors, and their immune systems and bodies are less mature. The purpose of this study was to compare the concentrations of the monoaromatic volatile benzene, toluene, ethylbenzene ...
متن کاملOccupational exposure of petroleum depot workers to BTEX compounds.
BACKGROUND Benzene, toluene, ethylbenzene and xylene (BTEX) are the most important toxic volatile compounds in the air and could be easily absorbed through the respiratory tract. In recent years, the risk of exposure to BTEX compounds, especially benzene as a carcinogen, has been considered in petroleum depot stations. OBJECTIVE To assess the occupational exposure of petroleum depot workers i...
متن کاملSpatiotemporal Monitoring of Urban Vegetation
Monitoring spatiotemporal changes in urban agglomorations will become increasingly important as the number and proportion of urban residents continue to increase. Intra-urban variations in vegetation abundance influence environmental conditions and energy fluxes by selective reflection and absorbtion of solar radiation, by modulation of evapotranspiration and by sequestration of pollutants. The...
متن کاملUrban Air Pollution Exposure – Measurement, Modeling and Assessment
Exposure to air pollution in city centers is of major concern because of its health-risks to urban dwellers, trafficcorridor users and even to in-transit commuters. The steady growth in traffic is the major source of toxic air pollutants in urban centers these days. Therefore, studying exposure to air pollutants in urban centers is of special interests to environmental health scientists. This s...
