Environmental and human health problems have been described as cancer of the last century by various international organizations. People who strive for development and living standards have created this problem themselves and are also affected by it themselves. No resource on earth is unlimited. This includes renewable resources. Pollution of the air, which is thought to never run out, reveals how scarce the resources are and how it affects people's future.

Air pollution is increasing with increasing urbanization, rapid industrialization and under-regulation of environmental protection, causing health and environmental problems in many countries.

According to the results of the research, there is air pollution in many cities which exceed the guideline values ​​announced by the World Health Organization. Given the fact that more than half of the world's population lives in cities, the magnitude of the problem is more clearly understood.

Many organizations draw attention to environmental problems in cities, state urgent action, point out the importance of air pollution, and endeavor to make a sustainable action plan for the near future and to obtain reliable data on air pollution sources, concentrations and effects.

Among the air pollutants, heavy metals are also noteworthy. Heavy metals are elements with metallic properties. In fact, living things need varying amounts of heavy metals, such as iron, copper, cobalt, manganese and zinc. Excessive amounts of these are harmful to the body. Apart from these, some heavy metals such as mercury and lead are not beneficial to living things, and they cause serious discomfort if they accumulate in the body.

Heavy metal measurements in ambient air are performed by accredited laboratories within the scope of imitation measurements. When making these measurements, the laboratories compare the results with the limit values ​​described in the legal regulations and published national and international standards.
