We present a mathematical model and simulation of a film biofilter for the treatment of gaseous effluents, using the MathCad Plus 6.0 program. The contaminant mixture included aromatic hydrocarbons such as benzene, toluene, ethyl benzene and xylene, dissolved in air. We applied the model through ...
After the episode that occurred in London in December
of 1952 in which more than four thousand people
died as a result of acute exposure to atmospheric
contaminants (particulate matter and sulfur dioxide,
principally), there are no doubts that air quality has
an important effect on the health of ...
A follow-up in 2013 of the indicators of pollution (temperature, hydrogen potential, salinity, dissolved oxygen, ammonium, nitrites, nitrates, orthophosphates, ortho silicates, biological oxygen demand, chemical oxygen demand, suspended solids) in surface water was performed, in order to estimate...
Toxic air pollutants, also known as hazardous air pollutants, are those that are known or suspected to cause cancer or other serious health effects, such as birth defects or adverse environmental outcomes. The aim of this research was to predict air toxics related health risks due to different em...

Emission Scenarios and the Health Risks Posed by Priority Mobile Air Toxics in an Urban to Regional Area: An Application in Nashville, Tennessee
Box-Jenkins Time Series (ARIMA) and the multivariate linear models (MLM) have been important and popular linear tools in air quality forecasting during the past decade for urban areas. On the other hand, artificial neural networks (ANN) recently have been used successfully as a nonlinear tool in ...

A hybrid ARIMA and artificial neural networks model to forecast particulate matter in urban areas: The case of Temuco, Chile
Air toxics concentrations and health effects that come from different sources emission scenarios by linking Models-3/CMAQ and cancer risk assessment were predicted. The year 1999 was used to emissions inventory and the year 2003 for meteorological data and modeling performance. To demonstrate the...

Health risk assessment posed by primary diesel particulate matter and vapor air toxics in Southeastern US
Temuco is a mid-size city representative of severe wood smoke pollution in southern Chile; however, little is known about the indoor air quality in this region. A field measurement campaign at 63 households in the Temuco urban area was conducted in winter 2014 and is reported here. In this study,...

Particulate air pollution and health effects for cardiovascular and respiratory causes over an industrial neighborhood; Linking epidemiological time series studies and the power of a health perception survey
The particulate matter pollution, induced mainly by the domiciliary wood heating, vehicular traffic, and industrial activity, has become the main source of concern of urban air quality in cities of colder climates. The city of Temuco, 800 km to the south of Santiago, Chile, suffers from severe wo...

Particulate air pollution and health effects for cardiovascular and respiratory causes in Temuco City, Chile
Air quality time series consists of complex linear and non-linear patterns and are difficult to forecast. Box-Jenkins Time Series (ARIMA) and multilinear regression (MLR) models have been applied to air quality forecasting in urban areas, but they have limited accuracy owing to their inability to...
