Modelling of Long-Range Transport Potential of Persistent Transformation Products... 

To better quantify the mobility of substances, indicators that can be calculated from the model results have been developed. Indicators for long-range transport potential are the spatial range [26,27], the characteristic travel distance (CTD) [33], the Great Lakes Transport Efficiency (GLTE) [34], and the Arctic contamination potential [35]. In the following two sections, we describe how such indicators have been adapted for transformation products. 

All the three groups of SVOCs concerned in this paper, namely PCBs, PBDEs and PAHs, are persistent and semi-volatile and subject to atmospheric transport to remote locations, through a series of deposition/volatilization hops, known as the grasshopper effect. As a result, these compounds have been detected in the Arctic and Antarctic samples in numerous studies. The major factors determining the long-range transport potential (LRTP) are the volatihty and the degradation rate, or half life of the SVOCs in the atmosphere.
