Jean-Paul Hettelingh, Coordination Centre for Effects (CCE), Workshop to promote the ratification of the protocol on heavy metals across the entire UNECE Region, Yerevan, May 2008 Definition of critical loads and objectives In general : –a quantitative estimate of an exposure to one or more pollutants below which significant harmful effects on specified sensitive elements of the environment do not occur according to present knowledge For heavy metals : –The critical load of a heavy metal is the highest total metal input rate (g ha-1 a-1) below which harmful effects on human health and ecosystems will not occur in an infinite time perspective, according to present knowledge Objective of the “critical load approach” in integrated environmental assessment : Deposition should not exceed critical loads to avoid harmful effects to a sustainable natural environment. Sustainable biodiversity is needed for Human Well-being.

Collaborative projects between National Focal Centres in EECCA countries and other institutions such as EMEP MSC-E, MSC-W and the EMEP Centre for Integrated Environmental Assessment Modelling (CIAM) is recommended.
