Air pollution from anthropogenic sources has been and continues to be considered a serious environmental problem affecting public health. Its seriousness lies in the fact that it raises the level of pollutants in places where their impact on human health is most likely. Therefore, air pollution is a major threat to public health worldwide. According to the World Health Organization (WHO) more than two million premature deaths per year are attributable to the effects of outdoor and indoor air pollution. More than half of this burden of disease is borne by populations in developing countries....

Gran parte de las actividades humanas, tanto industriales como comerciales, y los productos por ella generados dan origen a una mayor o menor contaminacion del medio ambiente. Una clase de estos contaminantes generados son los compuestos organicos volatiles (COVs). Los COVs son contaminantes primarios, es decir que por su naturaleza tienen efectos toxicos en la salud humana y pueden afectar al medioambiente por si mismos. Pero, al participar en reacciones fotoquimicas atmosfericas, algunos de ellos pueden generar contaminantes secundarios como O3 y PAN (nitrato de peroxoacetilo), productos...

Recent epidemiological studies show as chronic exposure to contaminants related to urban air pollution and industrial such as suspended particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), SO2, NOx and ozone produce adverse development and lung function in addition to increased respiratory morbidity, often expressed as a diagnosis of asthma or chronic obstructive pulmonary disease (COPD), and increased mortality, mainly in children. In particular, volatile organic compounds (VOCs) comprise an important group of air pollutants. Among these we can...
