Air pollution may possibly harm population in way subtle or show that they have not yet been deleted. For that reason, research is now under way to access the long-time effects of chronic exposure to low levels of air pollution what most people experience as well as to determine how air pollutant interact with one another in the body and with physical factor such as nutrition, stress, alcohol, cigarette smoking, and common medicine. Another subject of investigation is the relation of air pollution of cancer birth defects, and genetic mutations. A recently discovered result of air pollution is seasonal "holes" in the ozone layer in the atmosphere above Antarctica and the Arctic, coupled with growing evidence of global ozone depletion. This can increase the amount of ultraviolet radiation reaching the earth, where it damages crop and plant and can lead to skin cancer and cataracts.
Among new development has been growing problem of air pollution in Phnom Penh, linked mainly to the rapidly increasing volume of traffic. At the moment, Phnom Penh and in other major urban areas is at an early stage and is largely uncontrolled. Cambodia appears to be facing a growing air pollution challenge.
Even everyday levels of air pollution may insidiously affect health and behaviour. Indoor air pollution is a problem in developed countries, where efficient insulation keeps pollutant inside the structure.
