The objective of this study is to build a regression model of air quality by using the support vector machine (SVM) technique in the Avilés urban area (Spain) at local scale. Hazardous air pollutants or toxic air contaminants refer to any substance that may cause or contribute to an increase in mortality or serious illness, or that may pose a present or potential hazard to human health. To acco...

The concentrations of five hazardous air pollutants were simulated using the community multi-scale air quality (CMAQ) modeling system. Annual simulations were performed over the continental United States for the entire year of 2001 to support human exposure estimates. Results are shown for formaldehyde, acetaldehyde, benzene, 1,3-butadiene and acrolein. Photochemical production in the atmospher...

Approximately 100 billion aluminum cans are produced annually, mainly for the beverage industry. Early technologies for decorating the cans often used solvent-based coatings containing solvents at concentrations of -70% to 75% by volume (Randall 1992). The solvent composition was typically a mixture of aliphatic hydrocarbons, aromatics, ethers, cellosolves, and acetates. Unfortunately, this met...

Although researchers have begun making significant inroads into understanding the genetic and biological basis for autism spectrum disorders (ASDs) and other neurodevelopmental disorders, it's been estimated that environmental factors could account for just over half the risk of developing ASDs. 1 In this issue of EHP, researchers have used data from 1,767 women in the Nurses' Health Study (NHS...

Received: October 06, 2017 Revised: January 03, 2018 Accepted: February 02, 2018 Abstract: Introduction: Due to release of pollutants, chemical or hazardous materials into the environment from manmade or artificial sources, human being as well as animal populations are affected directly or indirectly through inhalation of air, intake of water, intake of food, dermal contact, etc. Then, human be...

Perchloroethylene, also known as tetrachloroethylene or perc, has been used safely in industry for over 50 years. It is an effective, nonfl ammable solvent that does not contribute to the formation of smog (ground-level ozone) or to the depletion of stratospheric ozone. The US Environmental Protection Agency (EPA) has approved the use of perchloroethylene as a replacement for stratospheric ozon...

Industrial air pollution is of major concern to upcoming Indian cities like Trivandrum and Pune in terms of industrialization and urbanization. Even the urban population is exposed to ambient air pollutants; on the other hand the sub-rurals contribute to the cigarette smoke and kitchen cooking fuels. A quantitative analysis on the mean concentration of SO2, NOX, and SPM in four different indust...

Asthma is one of the most common diseases in childhood, which has been increased during last decade because of epidemiological pattern changes with climate and industrialization of the communities. There are some controversies on the relationship between air pollution and asthma. Tehran, as the capital of Iran, is one of the densest populations and is one of the most polluted cities in the worl...
