Health Effects of Air Pollution

چکیده
An air pollutant is known as a substance in the air that can cause harm to humans and the environment. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. Pollutants can be classified as either primary or secondary. Air pollution, both indoors and outdoors, is a major environmental health problem affecting everyone in developed and developing countries alike. Air pollution has both acute and chronic effects on human health. Even relatively low concentrations of air pollutants have been related to a range of adverse health effects. Health impact of air pollution depends on the pollutant type, its concentration in the air, length of exposure, other pollutants in the air, and individual susceptibility. Air pollution can affect our health in many ways with both short-term and long-term effects. Different people are affected by air pollution in different ways. Some individuals are much more sensitive to pollutants than are others. Young children and elderly people often suffer more from the effects of air pollution. People with health problems such as asthma, heart and lung disease may also suffer more when the air is polluted. There are various air pollution control technologies and land use planning strategies available to reduce air pollution. The World Health Organization (WHO) Air quality guidelines (AQGs) are designed to offer global guidance on reducing the health impacts of air pollution.
