Purpose. Environmental pollution by toxic metals arises from industrial, agricultural effluents and waste disposal from various sources. Many industries such as metal plating facilities, mining operations and tanneries discharge waste containing heavy metal ions .Heavy metals are not biodegradable and can lead to accumulation in living organisms, causing various diseases and disorders. It is well known that some metals are harmful to life, such as antimony, chromium, copper, lead, manganese, mercury, cadmium, etc.; they are significantly toxic to human beings and ecological environments.

Methods. The main components of receipt of harmful substances into the atmosphere are emissions from high-temperature combustion products (exhaust gas vehicles, aircraft, industrial emissions and thermal power plants). Knowing the quantities of certain substances released into the atmosphere is a necessary and fundamental step in any environmental protection policy, which deals with current problems such as acidification, degradation of air quality, global warming and climate change, stratospheric ozone depletion, etc. This quantification, which is usually called "emission inventory", is carried out using specific rules that may vary from one inventory to another. On an international scale, harmonization work has been underway for several years between various international bodies (European Commission, United Nations Economic Commission for Europe, Intergovernmental Panel on Climate Change [IPCC, IPCC], EUROSTAT, International Energy Agency, etc.). This work is continuing together with the improvement of methodologies for estimating releases from various types of emitters.
