Some spectral lines are much more prominent, some elements/molecules will stay there longer, it can't be compared only by weight. Also, if Starship is successful as planned, means on average several tons launched per day, most of which mass to be deorbited just few years later. Starlink plans to deorbit thousands of satellites per year, V2 are 800kg already, likely getting heavier if launching gets cheaper.
