Heavy metal (HM) emissions (APE 005) - Assessment published Dec 2011
-
Across the EEA-32 countries, emissions of lead have decreased by 91%, mercury by 68% and cadmium by 70% between 1990 and 2009. For each substance, the most significant sources in 2009 are from energy-related sources associated with fuel combustion, particularly from public power and heat generating facilities, and from industrial facilities.
Much progress has been made since the early 1990s in reducing point source emissions of cadmium and lead (e.g. emissions from industrial facilities). This has been achieved through improvements in for example abatement technologies for wastewater treatment, incinerators and in metal refining and smelting industries, and in some countries by the closure of older industrial facilities as a consequence of economic re-structuring.
In the case of mercury, the observed decrease in emissions may be largely attributed to improved controls on mercury cells used in industrial processes (e.g. in the chlor-alkali process) including the replacement of old mercury cells by diaphragm or membrane cells, and the general decline of coal use across Europe as a result of fuel switching.
The promotion of unleaded petrol within the EU and in other EEA member countries through a combination of fiscal and regulatory measures has been a particular success story. EU Member States have for example completely phased out the use of leaded petrol, a goal that was regulated by Directive 98/70/EC. From being the largest source of lead in 1990 when it contributed around 73% of total emissions, emissions from the road transport sector decreased since then by nearly 99%. Nevertheless, the road transport sector still remains an important source of lead, contributing around 10% of total lead emission in the EEA-32 region. However since 2002 little progress has been made in reducing emissions further; 98% of the total reduction from 1990 emissions of lead had been achieved by 2002.
Environmental context: Heavy metals (such as cadmium, lead and mercury) are recognised as being toxic to biota. All have the quality of being progressively accumulated higher up the food chain, such that chronic exposure of lower organisms to much lower concentrations can expose predatory organisms, including humans, to potentially harmful concentrations. In humans they are also of direct concern because of their toxicity, their potential to cause cancer and their potential ability to cause harmful effects at low concentrations. The relative toxic/carcinogenic potencies of heavy metals are compound specific. Specifically, exposure to heavy metals has been linked with developmental retardation, various cancers and kidney damage. Metals are persistent throughout the environment, and cadmium, lead and mercury are among those heavy metals that are already a focus of international and EU action. These substances tend not just to be confined to a given geographical region, and thus are not always open to effective local control. For example, in the case of cadmium, much is found in fine particles which do not readily dry deposit, rather having long residence times in the atmosphere and hence are subject to long-range transport processes.
