Presentation of a General Algorithm for Effect-Assessment on Secondary Poisoning.II Terrestrial Food Chains

摘要

The concern of the study was whether the simple algorithm presented to be usedfor effect-assessment on secondary poisoning of birds and mammals in aquatic food chains can be applied for effect-assessment on birds and mammals in a terrestrial food chain as well. It was concluded that bioconcentration factors in terrestrial habitats are much lower than in aquatic habitats and are < 1 for many compounds (in standard situations). Based on this, another important difference between secondary poisoning in aquatic food chains and terrestrial food chains was found. Compounds for which secondary poisoning is a critical pathway in terrestrial food chains can not be characterized as being those compounds having a high accumulation potential, as is the case for aquatic food chains.
