The authors suggest pollutant-induced permeability changes cause chloroplast dehydration and ultrastructural changes.

e0“The increase density of the stroma, formation of fibrils, and general decrease in volume is probably the result of an increase dehydration of the chloroplasts brought on by permeability changes induced by the pollutants.”
