Inhalation of air pollutants causes distress to the respiratory system, which lead to development of chronic respiratory infections, and aggravation of ailments affecting the system. The air pollutants cause respiratory problems in various ways including blocking the air pathways after being deposited in the lungs, irritation and inflammation of the respiratory tract resulting to production of mucus and coughing. These effects increase the vulnerability of the affected person to developing infections of the respiratory system.
Numerous medical research studies on the effect of air pollution on children indicate that their health is more prone to the emissions than adults are (WHO, 2005). Polluted air causes adverse effects to the growth and development of both unborn and born children. Several factors contribute to the increased vulnerability of children’s health to air pollution. These include the continuing growth and development process of the lungs, incomplete metabolic systems and undeveloped immune systems that makes them susceptible to respiratory infections (WHO, 2005). These factors could lead to higher exposure of the children to air pollutants and increase the toxicity of the substances once they enter into the respiratory system. According to WHO (2005, p18) the effectiveness of the detoxification system in children improves with time, during prenatal and postnatal period. Hence, children at prenatal stage are most susceptible to air pollution because the lungs and the respiratory system are at critical stage of growth and development. When the developing lungs are exposed to air pollution, their optimal functional ability reduces and the abnormality continues to adulthood, causing reduced functional reserve of the lungs (WHO, 2005). Reduced functional reserve in adulthood increases the vulnerability of infections due to ageing and exposure to other pollutants, such as smoking and work related exposures (WHO, 2005,

These substances change the characteristics of the environment thereby posing a threat to the existence of humans, animals and other organisms. These pollutants can be primary or secondary in nature. Primary pollutants includes those which are directly released into the atmosphere such as from power generating plants while secondary pollutants are those which result from the chemical reactions that occur between the primary pollutants and the other elements present in the atmosphere resulting in their transformation to secondary type pollutants (Air pollutants General Overview).
(Wijetilleke & Karunaratne, 1995, p.10) There are many types of air pollution. The common types are acid rain, smog, greenhouse effect and damage in ozone layer. All these types can cause serious damage to human health (What is Air Pollution, n.d.). There are two main air pollutants that cause most damage to human beings and environment.
This is of particular concern to those that are children, as their small body weight and long-term lung development are at significant risk. Even before birth, exposure to air pollution has the potential to affect growth, development, and health of children; as they grow to maturity, health issues such as decreased lung function, cardiovascular disease, and even obesity and diabetes can occur.
Since air pollution has serious effects to the human health as well as other living organisms, there have been increasing concerns on how to prevent it or at least mitigate its effects in the world (Liu 11). National governments, international organizations, and individuals have developed policies and approaches of addressing the challenge of environmental degradation, which air pollution is a main contributory factor (Agarwal 17).
This essay refers to Beijing Municipal Environmental Monitoring Center, that reports current quality of air is above 300, which is considered hazardous by the World Health Organization. The researcher also discusses causes of air pollution, such as dense smog in the atmosphere and impacts on the people of Beijing.
Exposures to biologic, chemical and physical agents from the home environment can be linked to health-related factors. Death is by far the most serious among potential harms from air pollution, and this happens when one is exposed to excessive levels of air pollution (Schwartz, 2006).
Air pollution is dangerous to our health and long term exposure to air pollution can shorten our life. Early exposure to air pollutants can slow down development and growth of the lungs in children. In London, air pollution is decreasing over the years due to several steps taken by the government to minimize air pollution.
ths in the world today making it conceivably the largest single cause of death today With this possibility in mind, one can no longer view the innumerable industries disgorging toxic waste into the atmosphere as simply nuisances but latent killers. Additionally the simple
Therefore, the authors carried out a review to determine whether there was an association between particulate matter air pollution and human diseases. Their article sought to highlight the effects of ambient airborne particulate matter on the prevalence of human morbidity as
