(COL-1117-797910) Plant uptake of organic chemicals - the soil-air-plant pathway.

Finnegan, E¹, Collins, C¹, ¹ Imperial College, London, UK

ABSTRACT- The understanding of plant uptake of organic contaminants has expanded in recent years. Most notably there has been improvements in our understanding of the aerial deposition pathway and the influence of the soil-air-plant pathway. This paper will review and quantify the soil-air-plant pathway of plant contamination from soils polluted with organic chemicals. Relationships to describe the pathways will be presented to help those wishing to model this process. Finally the contribution of this process to the overall contamination of plants from polluted soils using a number of established models, some updated based on our findings, will be presented.

Key words: aerial deposition, plant contamination
