We investigated the issue of noise pollution in the Bidboland gas refineryby noise measurement and surveys. The Bidboland gas refinery has several process units.The sound pressure levels were measured at several places, such as units of 200, 300,400, 500, boiler, powerhouse area, cooling towers pumps, and maintenance area, and thecorresponding noise maps were produced by using sound plan softwa...

In the last years, the attention of the public community on electromagnetic pollution has continuously grown. In this paper we argue that the use of Geographic Information Systems in this domain should be encouraged as a valid support to the monitoring activities related to this phenomenon. In particular, our proposal of a visual environment, the Metaphor GIS Query Language is shown to provide ...

Measurement of the levels of ozone and carbon monoxide (a tracer of anthropogenic pollution) at three surface sites on the Atlantic coast of Canada allow the estimation of the amount of ozone photochemically produced from anthropogenic precursors over North America and transported to the lower troposphere over the temperate North Atlantic Ocean. This amount is greater than that injected from th...

Previously we identified associations between the mother's air pollution exposure and birth weight for births in Connecticut and Massachusetts from 1999-2002. Other studies also found effects, though results are inconsistent. We explored potential uncertainties in earlier work and further explored associations between air pollution and birth weight for PM10, PM2.5, CO, NO2, and SO2. Specificall...

The project’s idea is really simple: using the LabView environment, we have realized a virtual instrument able to get from the prototype data acquisition board for environmental monitoring parameters the information about air pollution factors like CO, H2S, SO2, NO, NO2 etc. In order to get effective information about those factors and the monitoring points, this intelligent measurement system,...

Introduction A critical issue in epidemiological studies of ambient air pollution is the measurement of pollutant exposure in the study population. Accurate characterization of air quality is necessary in any study relating exposure to health effects, and is essential in attempting to quantify risk estimates for specific exposure concentrations. Despite the importance of accurate air quality da...

background : studies have shown that noise pollution has harmful effects on human health. the sound of traffic is the main source of noise pollution in cities. the purpose of this study was to determine noise pollution using a geographical information system (gis) in the main streets of kashan, iran. methods: in this study, 180 noise samples were collected from 20 regions of the main streets in...
