This article seems to me to state the Grasshopper Effect as absolute fact and the definitive explanation for e.g. transportation of all pollutants to the poles. However, it's a theory and, like all scientific theories, comes with caveats and qualifications. We sort of touch on this in sentences like "Recent studies conclude that for most pollutants slower degradation in colder temperatures is a more important factor in accounting for their accumulation in cold region than global distillation" - but the point could/should be made clearer? So... we probably need a better evaluation of the scientific evidence... description of different models... some discussion of single hop version multi-hop transport... and some idea of where the theory came from to begin with, mentioning e.g. Rappe, Goldberg (who gave us the phrase "global distillation"), and Ottar.

Key papers include....

Rappe C, 1974. Chemical behavior of pesticides. [Don't have the citation to hand]

Goldberg ED, 1975. Synthetic organo-halides in the sea. Proceedings of the Royal Society, London, Series B 189, 277-289.https://ui.adsabs.harvard.edu/abs/1975RSPSB.189..277G/abstract

Ottar B, 1981. The transfer of airborne pollutants to the Arctic region. Atmospheric Environment 15, 1439-1445 https://www.sciencedirect.com/science/article/abs/pii/0004698181903504
