Sources of Air Pollution In general, the air pollution sources are categorized into mobile sources and stationary sources. Stationary sources are mostly industrial complexes such as factories and electric generating plants. Mobile sources are vehicles, on- road, off-road. The quality of the indoor air also plays a significant role as far as health is concerned. However, the awareness among the public in this aspect is increasing, and they have started realizing the issues that arise with poor indoor air quality (IAQ). This is applicable both to workplace and homes. AIR Toxins and Health Effects 1- All the heating appliances and gas fuelled appliances release NO2. However, the results for the studies conducted with people with adverse respiratory issues and inhalation of NO2 are inconclusive. The effects of NO2 exposure have on adult women, children with respiratory problems, asthma or atopic issues are high. Further, results showed that NO2 inhaled by people with asthmatic issues show enhanced reactions to the inhaled allergens. The NO2 levels are reported to be high in the lower income households as the size of the apartments are small, ventilation is poor. As the nitrous oxide is acidic in nature, it easily causes respiratory damages in people who have asthmatic issues at a concentration level of 650 ppb for over 3 hours easily (Weisel, 2002). 2- Sulfur dioxide is associated with the high amount of adverse health issues which include short-term respiratory morbidity and even fatality. As it is a combustion product, which is a product of fossil fuels, it can be combined along with aerosols, and other particles in the air to form a very complex group, which could be very complicated pollutants and allergen.

This is applicable to home as well as any other non-industrial occupational settings (Reisen & Meyer, 2011; Walsh, 2011). Conclusion In conclusion both outdoor and indoor air quality play a significant role as far as health is concerned. NOx, SO2, VOCs and some organic compounds are real threat for human health. However few studies and researches have being conducted specially in Australia. In order to overcome the health effect raised as a result of air toxic more awareness among the public in this aspect has to be increased.

According to research, World Health Organizations reported that Asian air pollution, “is responsible for an estimated 537,000 premature deaths annually with indoor air pollution being responsible for over double this number of deaths” (Schwela).

The levels reached during this crisis called for civilians to stay inside where they were advised to wear masks both indoors and outdoors. There is a growing need for intervention as researchers look to identify the most effective measures to protect human health and the environment. To identify the most effective measures, scientists look at the causation of the pollution. Although there is no direct single cause for the air pollution, all factors combined contribute to this issue. Asian air pollution threatens the environment and public health; it is a direct result of industrial pollution, biomass pollution, and forest fire pollution.

    Air pollution is the insertion of harmful particles into the Earth's atmosphere, which is a complex system essential to support life on Earth. One type of air pollution is known as indoor pollution. There are many causes of indoor air pollution, but the leading ones include overuse of pesticides, household products, tobacco, and any other products that release toxic gases or particles. “Indoor air pollution from biomass and coal fuels affects one half of the world population, and about 80% in low-income countries of Africa and South Asia” (CHERG). In fact, more than 2.9 billion people burn wood and charcoal to perform daily routines. According to The World Health Organization (WHO), 4.3 million people in 2012 have lost their lives due to indoor air pollution. When comparing this to other major issues such as global warming, studies “suggest that between 30 and 150 times more people are killed due to indoor air pollution than global warming” (Lomborg).

    In conclusion, air pollution affects the immune system, making it weak and vulnerable to certain bacteria, illnesses, viruses and foreign invaders. Common diseases that are affected the most include asthma and allergies. Air pollution in general has been seen to modify the immune system's handling of particular allergens. The exposure to toxins like dioxin can cause serious health problems for people. Having long-term exposure to this toxin is connected to weakening of the immune system, as well as the nervous system, endocrine system and certain reproductive functions. Hence, everyone has a particular level and exposure of dioxins in the body.

Pollutants within the air are measured in terms of particulate matter (PM); or the number of particles of potentially hazardous substances as a percentage of air. Outdoor air pollutants can create acid rain, which affects the environment and depletion of the ozone layer by chlorofluorocarbons (CFC's), which increases the risk of skin cancer and cataracts in human individuals.

    The polluted air we breathe everyday can cause serious health problems to us or even death. The short term effects of breathing polluted air are headaches, nausea, and allergic reactions. Short term effects can also aggravate the medical conditions of individuals with asthma and emphysema. The long term effects, which are more serious and deadly are, lung cancer, chronic respiratory disease, heart disease, and damage to the brain, nerves, liver, and kidneys. Air pollution also has a bad effect on women who are pregnant. Research has shown that women who come in contact with high levels of pollution, are more likely to have a premature or early baby (David Anderson). Now, women who protect themselves more from all the pollution are more likely to have a healthier baby. Another research also shows that air pollution kills about 3.3 million people every year. The study also proves that if we continue to pollute our air the way we 're doing it right now, the yearly deaths will double to 6.6 million people in 2050 (David Anderson). About 6 percent of global deaths each year are caused by air pollution. Scientists also say that air pollution kills more than both HIV and malaria each year, which I find pretty
