University of Southern California study finds aluminum oxides in Earth 's atmosphere could increase 650% in coming decades due to number of defunct satellites burning up during reentry.
Spacecraft bodies are made of aluminum, which gives rise to aluminum-oxides when incinerated.
The study is the first to model the generation of these pollutants in the atmosphere and estimate the evolution of their concentrations based on forecasted proliferation of satellites.
The ozone hole above Antarctica has grown to three times the size of Brazil .
The chemistry and physics of these reentry byproducts as they cool down and settle in the atmosphere are not the subject of this study.
The study was published in the journal Geophysical Research Letters on June 12 .
