Abstract Air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment.

Keywords: Air pollution, cardiovascular diseases, environment, human health, respiratory tract diseases, toxicology. Environmental damages Ecologically, air pollution can cause serious environmental damages to the groundwater, soil, and air. Air pollutants and their toxicities Every material in the air which could affect human health or have a profound impact on the environment is defined as air pollutants.

The Different Types And Effects Of Pollution

Particle pollutants Particle pollutants are major parts of air pollutants. Ground-level ozone O 3 with the chemical formula of O 3 is a colorless gas which is the major constituent of the atmosphere.

Carbon monoxide CO is a colorless and odorless gas, which is produced by fossil fuel, particularly when combustion is not appropriate, as in burning coal and wood. Sulfur dioxide SO 2 is a colorless, highly reactive gas, which is considered as an important air pollutant.

Nitrogen oxide Nitrogen oxides are important ambient air pollutants which may increase the risk of respiratory infections. Lead Pb or plumb is a toxic heavy metal that is widely used in different industries. Other air pollutants Other major air pollutants that are classified as carcinogen and mutagen compounds and are thought to be responsible for incidence and progression of cancer in human include VOCs such as benzene, toluene, ethylbenzene, and xylene, PAHs such as acenaphthene, acenaphthylene, anthracene, and benzopyrene, and other organic pollutants such as dioxins, which are unwanted chemical pollutants that almost totally produced by industrial processes and human activity.

Health hazards In terms of health hazards, every unusual suspended material in the air, which causes difficulties in normal function of the human organs, is defined as air toxicants.

Respiratory disorders Because most of the pollutants enter the body through the airways, the respiratory system is in the first line of battle in the onset and progression of diseases resulted from air pollutants. Cardiovascular dysfunctions Many experimental and epidemiologic studies have shown the direct association of air pollutant exposure and cardiac-related illnesses. Neuropsychiatric complications The relationship between exposure to air suspended toxic materials and nerve system has always been argued.

Other long-term complications Skin is the body's first line of defense against a foreign pathogen or infectious agent and it is the first organ that may be contaminated by a pollutant.

Air pollution in Iran Air pollution in Iran as a developing country has recently caused several health and environmental problem. Practical measures to reduce air pollution in Iran The industrialization of societies is necessary to develop, but a long-term health problem and ecological impacts of such growth should always be considered prior to imposing a large financial burden on the societies. Some recommended strategies to reduce the air pollution in Iran are summarized as the followings: Standardization of vehicle's fuel as much as possible and also finding a new source of energy for motor engines has attracted great attention.

They should be implemented soon in big cities of Iran Increasing the cost of fuel in Iran can be considered as an effective solution to reduce the proportion of air contaminants. According to the report by Barnett and Knibbs, higher fuel price is associated with lower air pollution level[ ] Imposing penalties for polluting industries and implementing low tax policy for clean technologies. These plans may contain discount on taxes or other financial supports for customers and producers Since the phenomenon of air pollution was a global issue over the centuries since the industrial revolution, it is proposed to establish an interdisciplinary academic field on air pollution.

It is also suggested that more communication and collaboration between specialists in different sciences including toxicology, environmental health, analytical chemistry, mechanics, and applied physics will be performed Continuous monitoring of air quality, designing and developing tools to identify the pollutants, finding the origin of the particles, and the use of particulate filter for diesel engines and other nonroad cars are other suggested practical approaches to reduce air pollution Extensive media campaign to increase public awareness about air quality, environmental, and public health issues.
