Barely any in a grand scheme of things.

As of today it's claimed some parts fell in Indian ocean the where the rest fell is so far unknown but could apparently be seen over Malaysia.

Is that a trick question?
"This thing is a massive 21t hulk of metal"
Probably less than the total accumulation from meteorites. OTOH 21t is only a fraction of the original mass of the rocket and much of that (fuel and more) gets burned up during the launch and the reentry of the first, second, (and third? and fourth?) stages. Any spacecraft that uses retrorockets will add even more "pollution" to the "atmosphere".
I have seen numerous complaints based on people speculating about effects on the ocean and the atmosphere of huge quantities of the ammonium perchlorate used in the solid rocket boosters used on the space shuttle and other rockets. I don't know if their concerns are valid or not.
