Abstract: | The measures undertaken for reducing the impact of POPs on the environment are discussed in international conventions concerned with these substances and are related to the reporting of obligations which should ensure the control of their implementation and verify the effects of these measures on the environment. An essential element of this reporting involves the data concerning the emissions and environmental impact of these substances in emission inventories. A summary of the current status of emission inventories for POPs with a special focus on atmospheric emissions under EMEP is also presented. There are considerable uncertainties of reported emission data by the individual countries and in expert evaluations regarding marine and atmospheric impacts. Harmonized instruments for emission evaluation are required and under development in the form of guidance documents for the marine environment in ‘Harmonized Quantification and Reporting Procedures for Hazardous Substances (HARP-HAZ)’ and under EMEP in the ‘Atmospheric Emission Inventory Guidebook for UNECE/LRTAP’. The problems and the reasons for uncertainties in the quantification of environmental impacts are presented using the example of lindanes (hexachlorocyclohexane, HCH), polychlorinated biphenyls (PCB), polycyclic aromatic hydrocarbons (PAH) und hexachlorobenzene (HCB). |
