A critical analysis of Chile's National Air Quality Information System(NAQIS) is presented, focusing on particulate matter (PM) measurement. This paper examines the complexity, availability and reliability ofmonitoring ...

The mass concentration of atmospheric particulate matter (PM) has been systematically used in epidemiological studies as an indicator of exposure to air pollutants, connecting PM concentrations with a wide variety of human ...

High concentration of fine airborne particulates is considered one of the major environmental pollutants in Santiago, the Chilean Capital city, which in 1997 was declared a PM10 saturated zone. To date there is no control ...

Air pollution problems can be large, complex, and ill-structured. They can vary from location to location and combine many complex components: urban expansion, increasing vehicles and industrial emissions, biomass burning, ...

This study analyzed air quality in terms of the concentrations of sub-10 mu m (PM10) and sub-2.5 mu m particulate matter (PM2.5) recorded at 23 automated public monitoring stations located in 16 cities in south-central ...

South America is one of the most vulnerable areas to stratospheric ozone depletion; consequently, an increased amount of UV radiation reaches the Earth's surface in this region. In this study, we analyzed the long-term ...

To improve the current understanding of the ammonia distribution in the major urban area of Chile, measurements of atmospheric NH3 were collected in Santiago during three sampling periods (25 April to 27 May, 11 to 26 ...
